Kamchatka Leaf Warbler in Shanghai

Seen at Pudong’s Cape Nanhui on Sun. 4 June 2017: Kamchatka Leaf Warbler Phylloscopus examinandus. Veteran British birder Michael Grunwell and I found our 4 Kamchatkas in Microforest 4 (30.953225, 121.959083), the largest of the tree plantations on the landward side of the sea wall. The species is an all-time first for the Shanghai eBird list.

Just after sunrise, Michael and I, as is our wont, were doing “drive-by birding”creeping along the edge of the road, listening out for birds. Suddenly, I heard an unfamiliar sound.

My gut said, “Hard, loudTaiga Flycatcher?”

Taiga was not even close, of course. Note, however, what my gut was not saying: “Arctic Warbler,” a bird whose call I know well. This call was decidedly not an Arctic’s, though it soon dawned on us that we were hearing some type of leaf warbler.

To see why my gut did not say Arctic, compare my recordings of the tight “tzit” call of Arctic Warbler with the looser call of Kamchatka Leaf Warbler:

Arctic Warbler Phylloscopus borealis, Yangkou-Rudong, Jiangsu (32.560095, 121.041956), 16 May 2015 (00:09; 1.9 MB)

Kamchatka Leaf Warbler P. examinandus, Microforest 4 (30.953225, 121.959083), Cape Nanhui, 4 June 2017 (00:25; 4.9 MB)

Michael and I skidded to a stop and poked our heads into the green tangle of locust trees. The call was being followed by a song. Only upon hearing the song did I think of Arctic Warbler. But here too, the song, though similar, was distinctive—wavier than the straight trill of Arctic. Look at the spectrograms below.

Spectrogram

The spectrogram above is of my recording 4 June 2017 of Kamchatka Leaf Warbler. Note the pattern: downward sweeps followed by an upward sweep. No one would liken that song to an insect’s. Below, the spectrogram of my 2015 recording of the song of Arctic Warbler. Note the straight, cricket-like trill.

Spectrogram

Here are the recordings whose spectrograms are shown above:

Arctic Warbler, Yikesama National Forest, Hulunbeier, Inner Mongolia (52.150833, 121.465639), 16 July 2015 (01:00; 3.2 MB)

Kamchatka Leaf Warbler, Microforest 4, 4 June 2017 (00:48; 9.3 MB)

After hearing several song-call cycles, Michael, my more experienced partner, first said the words “Kamchatka Leaf Warbler.”

Michael has birded the Indonesian islands of Flores and Komodo, where Kamchatka Leaf Warbler winters. Michael said that, last winter, walking through the forests there, he heard dozens of times the call of P. examinandus.

“I know that call,” Michael said.

I whipped out my Olympus DM-650 voice recorder and recorded the calling and singing warbler. Meanwhile, we caught our first glimpse of the individual. It was clearly an “Arctic-type” leaf warbler.

What is an “Arctic-type” leaf warbler? An Arctic-type leaf warbler is a member of one of four closely related taxa divided among three species: Japanese Leaf Warbler Phylloscopus xanthodryas, Kamchatka Leaf Warbler P. examinandus, and Arctic Warbler P. borealis borealis and P. b. kennicotti.

Leaf-warbler expert and Shanghai Birding member Per Alström is the person most responsible for our current understanding of Arctic-type leaf warblers. Alström’s PDF, from which this page is taken, is a handy introduction to leaf warblers in China and is downloadable through shanghaibirding.com.

Arctic Warbler is by far the most widespread breeder in the complex. P. b. borealis breeds across northern Eurasia, from Scandinavia to northeast China and the Russian Far East. P. b. kennicotti breeds in western Alaska.

As their names suggest, Japanese Leaf Warbler breeds mainly in Japan (Honshu, Shikoku, Kyushu), Kamchatka Leaf Warbler mainly in the southern Kamchatka Peninsula (as well as on Hokkaido and Sakhalin and in the Kuril Islands).

In 2010 Shanghai Birding member Per Alström et al. proposed the current way of viewing the Arctic-type warblers. Previously, the taxon examinandus was putative, not even reaching the subspecies level; Alström and his team showed that examinandus, with its distinctive song and call, merits recognition not as a subspecies of Arctic Warbler but as a species in its own right.

Of the three Arctic-type species, Japanese Leaf Warbler most stands out, being on average yellower than the two others. Arctic and Kamchatka look much more alike.

There are, however, some slight differences. Kamchatka is said to have a “marginally longer bill, tarsi and tail” than Arctic (del Hoyo & Collar). Sure enough, the Kamchatka I photographed is long-billed. Take a look below.

Arctic Warbler (top) and Kamchatka Leaf Warbler. Both birds show the classic features of Arctic-type warblers, among them a long supercilium that does not reach bill base, a dark smudge on the lower mandible, and mottled ear coverts. Kamchatka is said to be slightly greener on average than Arctic, a description that these photos do not contradict. The bill of Kamchatka is also marginally longer than Arctic’s, and in these profile shots one notes the longer bill of the Kamchatka and the stouter bill of the Arctic. I would not suggest basing an Arctic-Kamchatka ID on plumage and bare parts. Plumage and bare parts can, however, enhance the quality of a song- or call-based ID.

Michael and I heard our loudest song and calls during that first, early morning encounter. However, we heard Kamchatka calling throughout the day.

Our new Shanghai record, combined with late-May and early-June records from nearby Zhejiang, suggests that in this region, once the wave of Arctics passes through around 15 May, Kamchatka Leaf Warbler may be the Arctic-type to look out for.

‘One of My All-time Ornithological Highlights’

“I have thought a lot about yesterday and can honestly say, it must be one of my all-time ornithological highlights.”

— Dr. Mike May, message to Craig Brelsford, 14 May 2017

Those are the words not of a new birder, but of a highly experienced visiting birder with thousands of birds on his life list who resides in bird-rich Extremadura, Spain.

Birding Pudong’s Cape Nanhui at the height of the spring migration left Mike May open-mouthed. Should anyone be surprised? The most southeasterly point of Shanghai is a world-class birding site.

Mike’s 92-species day, Sat. 13 May 2017, with Beijing-based Swedish birder Jan-Erik Nilsén and me included ultra-rarities such as Orange-headed Thrush as well as Pallas’s Grasshopper Warbler and Lanceolated Warbler. A pair of sub-adult Black-faced Spoonbill were getting by on the ever-shrinking pools at the beleaguered site.

These records brought the all-time list for Cape Nanhui to 288 species, according to eBird—making Cape Nanhui the second-hottest birding hot spot in China.

Let me say that again: Of the thousands of birding spots in this vast, mega-diverse nation, the cape 60 km southeast of People’s Square is second only to Baihualing in Yunnan in species noted.

Sound unbelievable? Let me say something even more unbelievable: Not only is this rich spot completely unprotected, with not even a square meter preserved in any legal way; but it is, to the contrary, being actively destroyed, even as I tap out these words.

The backdrop to the work of Mike, Jan-Erik, and me was fleets of bulldozers and backhoes, busy throughout the weekend. They clattered and clanged, and the pumps transferring water into the newly dug canals whirred and chugged.

The pace of transformation is faster than ever now.

“Nanhui is gone,” my partners and I said.

A major ecological area, a place combining ease of access to millions of residents of Earth’s largest city and a favorable position on Earth’s greatest migratory flyway, is being utterly transformed.

While the Cape Nanhui that I have long known falls, huge tracts of adjacent tidal mudflat are being reclaimed, adding dozens of square kilometers to the land area of Cape Nanhui. Birding there in theory could have a future. A Cape Nanhui Nature Reserve could be set up in the new area.

Where Black-faced Spoonbill once foraged, digging machines now crawl. Where once one savored the sound of Marsh Grassbird and Reed Parrotbill, now one cringes at the clanging of machines. No place in mainland Shanghai matches Cape Nanhui as a magnet to migrating birds. Cape Nanhui is one of the best birding hot spots in China, and it is not only completely unprotected, but it is also being actively destroyed. (Craig Brelsford)

But even as the Cape Nanhui we know falls, no one, to my knowledge, has hastened to reassure conservationists that areas in the newly reclaimed land will be set aside for birds.

In the city-province of Shanghai, which is the size of the U.S. state of Delaware, a few places have indeed been set aside, among them Chongming Dongtan. But those reserves are small, on remote islands far from mainland Shanghai, and practically unreachable by the millions of middle-class Shanghainese who lack a car.

Cape Nanhui, by contrast, is easily reachable from the city. And it is the one place where masses of bird lovers can conveniently get a taste of the grand spectacle that is spring migration along the east coast of the Eurasian supercontinent.

That opportunity is being taken away, not only from the birders alive today, but also from the birders of the future.

THE THRILL OF NANHUI IN MAY

Our agony over the fate of Nanhui was tempered by the joy of birding. Orange-headed Thrush showed up Saturday at the Magic Parking Lot (30.884898, 121.968229). With the two vertical bars on its face, our specimen was either of race melli (breeds Guangdong, etc.) or courtoisi (Anhui).

On Sunday the Magic Parking Lot delivered singing Grey-crowned Warbler Seicercus tephrocephalus, and in Microforest 2 (30.926013, 121.970705) an appearance was made by Alström’s Warbler S. soror. Neither breeds in the region; both are very rare vagrants to Shanghai.

Iron Track (31.003613, 121.907883) gave us singing Yellow-breasted Bunting in full breeding finery and singing Pallas’s Grasshopper Warbler. I captured the latter’s song, rarely heard in Shanghai.

The Marshy Agricultural Land (30.850707, 121.863662) near Eiffel Tower was highly productive, yielding Lanceolated Warbler, Forest Wagtail, and Striated Heron.

A DISCUSSION ABOUT SEICERCUS

Per's PDF
Some of the more challenging Seicercus warblers. This graphic was created by Shanghai Birding member Per Alström for a presentation he made to the Beijing Birdwatching Society in 2012. The PDF is downloadable through shanghaibirding.com.

Shanghai Birding is the WeChat companion to this Web site. Our members include everyone from persons brand-new to birding to some of the most knowledgeable birders in China. We discuss everything from the most common species to the most arcane.

Here is an edited transcript of a recent conversation on Shanghai Birding about the Seicercus warblers at Cape Nanhui:

Join Shanghai Birding for the very latest bird sightings in Shanghai.

Paul Holt: Can you post your recording of yesterday’s [14 May 2017] Alström’s Warbler as well please, Craig?

Craig Brelsford: Will post after I get home. Meanwhile, have you assessed the recording I posted yesterday morning? Do you agree it’s Grey-crowned Warbler? Jonathan Martinez, I’d like your view, too!

Craig Brelsford had earlier posted these sound recordings:

Grey-crowned Warbler Seicercus tephrocephalus 1/3, 14 May 2017, Magic Parking Lot (30.884898, 121.968229), Nanhui (00:36; 3 MB)

Grey-crowned Warbler 2/3 (00:49; 3.6 MB)

Grey-crowned Warbler 3/3 (01:08; 4.3 MB)

PH: Yes, Grey-crowned Warbler!

PH: For what it’s worth, while there are probably 30+ records of “golden-spectacled warblers” from coastal Hebei, very, very few have been as well documented as Craig’s and team’s recent Grey-crowned. Many have been photographed but far fewer sound-recorded. Alström’s is so far the only one so far known to breed north of the Qinling Shan (it’s a scarce and very local breeder at two, possibly three, sites in Beijing). Personally I’ve never seen soror in coastal Hebei (nor am I aware of any being sound-recorded there), but I have noted (and sound-recorded) 2 Bianchi’s S. valentini and 1 Martens’s S. omeiensis in coastal Hebei. I understand that the only (?) three coastal Hebei birds that have been captured and had their DNA compared have all been omeiensis. We’re very, very far from ascertaining the true statuses of these Seicercus in our area, but you perhaps should/might see more in Shanghai and coastal Zhejiang. As many of you already know, there are some excellent sound recordings of these on Per’s site.

CB: Great analysis, Paul, and great that you point out the resources on Per’s site. Jan-Erik and I got good sound recordings of the purported soror yesterday, and Charles Wu and I got some good shots, among them images of the outer tail feathers, which definitely had some white in them.

CB: Grey-crowned Warbler appeared in the microforests almost exactly a year ago: https://www.shanghaibirding.com/2016/05/20/great-records/

PH: Excellent, Craig. As you know they’ve all got white in their outer tails. Alström’s (aka Plain-tailed) doesn’t have much …

CB: Right, Paul; thanks. The discussion yesterday was one of comparison and degree. How little must the white be in the tail, we were asking ourselves, for a Seicercus to “qualify” as Alström’s/Plain-tailed? Was the white in our photos a little or a lot? We ended up thinking a little, and that and the song we recorded led us to a determination of soror. I’ll post my photos and recordings as soon as I’m home.

PH: Personally, Craig, I find it very difficult to judge the amount and distribution of white on the tails of these Seicercus in the field and think that a good photo with the tail splayed would really be necessary. Even then, the differences are small and subtle. Tricky group!

Jonathan Martinez: Regarding the ID of these Seicercus, I have found that call is by far the easiest way to ID them. They all have a characteristic call. Some of them, like Alström’s or Bianchi’s, are usually quite vocal; others not as much. It requires much more experience or use of sonogram to ID them by song, but a few of them (Alström’s especially) include their call in their song, and some of them (Grey-crowned, Martens’s) include a trill in their song. Others do not (Alström, Bianchi’s). ID-ing them on plumage is, of course, a level up.

John MacKinnon in Shanghai

On Sat. 8 April 2017 I birded Cape Nanhui with John MacKinnon. John is co-author of A Field Guide to the Birds of China, the most influential book ever written about China’s birds. On John’s first visit to the tip of the Shanghai Peninsula, we noted 84 species. John and I were joined by veteran birders Michael Grunwell and Russell Boyman and the outstanding high-school birder Larry Chen.

We gave John the Grand Nanhui Tour, starting at Luchao to the south and ending 30 km north at Binhai. Heading back to the city, we made a brief stop at the sod farm just south of Pudong Airport, where we found a single Oriental Plover.

Russell Boyman (L) examines Oriental Plover 8 April 2017 at the sod farm south of Pudong Airport (31.112586, 121.824742). Conditions at the sod farm were decidedly not favorable to a plover. The jets were noisy, the farmers were busy, and there was a whiff of pesticide in the air. Why would the plover choose such a subpar area? Because the sod farm roughly approximates the steppe habitat required by the East Asian specialty. Oriental Plover are long-distance athletes, marathon runners between Australia and Mongolia, and incredibly tough. Despite the poor habitat, our bird likely will survive its brief visit to Shanghai and muscle its way up to the breeding grounds. For more on Oriental Plover in Shanghai, see my post Rites of Spring. (Craig Brelsford)

Nanhui yielded 23 Marsh Grassbird performing the song flight at three locations, and we saw 10 Endangered Great Knot and 1 Near Threatened Curlew Sandpiper. We had a pair of Rufous-faced Warbler and a Common Starling.

Also: Garganey 57, Greater Scaup 1 (Dishui Lake), Little Curlew 31 (flock), Sharp-tailed Sandpiper 11 (first of season), Red-necked Stint 1 (first of season), Wood Sandpiper 1 (first of season), Peregrine Falcon 1, Dusky Warbler 1 at Magic Parking Lot (possibly wintered there), and Reed Parrotbill 18.

GETTING TO KNOW JOHN MACKINNON

John MacKinnon wrote the most influential field guide ever published about China's birds.
John MacKinnon co-authored the most influential field guide ever published about China’s birds.

Our partner, John MacKinnon, co-authored A Field Guide to the Birds of China. Published in 2000, the book has sold more than 50,000 copies and remains the only bird guide in English covering all China. John also wrote the first and second guest posts in the history of shanghaibirding.com.

John is witty and a fine storyteller. He had us roaring with tales drawn from his six decades as a researcher in Asia. The funniest story was about the doctor back home in Britain. Every time John straggled in, the doc would call in his students, so that they could study the strange new tropical disease John had contracted.

“I never cared about my health, because I never expected to live this long!” John said.

John also talked about his masterpiece, A Field Guide to the Birds of China.

It is difficult to overestimate the importance of the Field Guide. Had it merely been a window for Westerners to the birds of the world’s most populous country, then John’s work would have been important enough. The Field Guide, however, in translated form has introduced tens of thousands of Chinese to the birds of their own country. John’s Chinese name, Mǎjìngnéng (马敬能), is known by every birder in China.

John faced obstacles unknown to field-guide writers in North America and Western Europe, where birding has been practiced for 200 years. His sources were often thin, he said.

“For range maps, I had nearly nothing from Russia,” John said. “A Chinese book had ranges stopping at the Chinese border. Another book had no paintings, only descriptions.”

To critics who unfairly compare John’s Field Guide to field guides covering more developed parts of the world, John had this to say:

“You’ve got to finish something. We finished the book. We could have waited and said, ‘Oh, another species has been split, we must revise,’ but at a certain point you have to say, ‘We must go with what we’ve got.’”

To this day, no Westerner has repeated John’s feat. Others talked; John acted. One can imagine the feeling of accomplishment in John’s heart.

John is a handy photographer and got off some good shots, three of which are displayed in the Day List at the bottom of this post. Here are some photos I took of the pioneer birder and naturalist.

MARSH GRASSBIRD ON THE BRINK

Marsh Grassbird were singing in the large reed beds at Nanhui. They were most conspicuous at the reed bed south of the Holiday Inn (30.870711, 121.942976). The species, listed as Near Threatened by IUCN, was also noted in the pristine reed bed (30.931790, 121.949169) associated with the defunct wetland reserve.

Marsh Grassbird
Helopsaltes pryeri sinensis at the large reed bed (30.870711, 121.942976), Cape Nanhui, Shanghai, 8 April 2017. Marsh Grassbird is among the least-known members of Helopsaltes. The populations at Cape Nanhui went unmentioned by Kennerley and Pearson in their landmark book Reed and Bush Warblers (Christopher Helm 2010). Kennerley and Pearson were aware of the breeding population on Shanghai’s Chongming Island but even there could not say for certain whether the grassbirds were residents or summer visitors. Part of the reason for the lack of knowledge is the extreme shyness of the bird. Outside breeding season, when it undertakes song flights, Marsh Grassbird remains hidden deep within the Phragmites reed beds that are its preferred habitat. The other reason is the extremely fast rate at which its reed-bed home is being destroyed. At Cape Nanhui and other places in China, this Near Threatened species could disappear before researchers get a chance to study it. (Craig Brelsford)

The reed beds at Cape Nanhui may be the last stronghold of Helopsaltes pryeri sinensis on the Shanghai Peninsula. The species is highly dependent on large reed beds. In areas where only strips of reeds remain, the song of Marsh Grassbird is never heard. Its partner species, Reed Parrotbill, a candidate for official bird of the city-province of Shanghai, is only slightly less dependent on large reed beds.

One of the areas where last year my partners and I noted Marsh Grassbird performing its song flight has been flattened. No song of Marsh Grassbird was heard there Saturday. A few Reed Parrotbill were calling in one of the strips of reeds left standing.

Much needs to be learned about Marsh Grassbird in Earth’s largest city. Birders, look for the fluttering song flight, and listen for this song:

Comparing Blyth’s Pipit & Richard’s Pipit

With more and more birders operating in Shanghai, more and more vagrant birds are bound to be discovered. One possibility is Blyth’s Pipit Anthus godlewskii (photo above, L), a species similar to our familiar Richard’s Pipit A. richardi (R). Blyth’s breeds mainly in Mongolia, occurs on passage in central China, and winters mainly in India, so any records here would be of extralimitals. Let’s examine here how to separate the two pipits.

Comparison of pipits
Comparison of adult-type Richard’s Pipit Anthus richardisinensis‘ (1) and adult Blyth’s Pipit A. godlewskii (4). The population group A. r. ‘sinensis’ occurs in southeast China south of the Yangtze River. Structurally, ‘sinensis‘ is the smallest group in Richard’s, with proportions recalling Blyth’s. Note however the blackish centers to the median coverts (2, 3). In adult-type Richard’s (2), the centers are triangular and tinged rufous at the edges. In adult Blyth’s (3), the centers are squarish, less rufous-tinged, and more clear-cut. 1, 2: Cape Nanhui, December. 3, 4: Hulunbeier, Inner Mongolia, July. (Craig Brelsford)

The key to getting a Blyth’s in Shanghai is paying attention to the many Richard’s Pipit that we see in the area. Anthus richardi is more or less a passage migrant in the Shanghai area and is recorded here regularly in spring and autumn. Some are present in winter; Elaine Du and I had a “sinensis” last week, the ID’ing of which led to this post.

flight song
More views of Blyth’s Pipit performing flight song, Inner Mongolia, July. In Pipits and Wagtails, Shanghai Birding member Per Alström et al. write that in flight, Blyth’s Pipit ‘often recalls one of the smaller pipits rather than Richard’s’ (237). Note however that Anthus richardi ‘sinensis,’ a population group within Richard’s Pipit often found in Shanghai, is structurally similar to Blyth’s. (Craig Brelsford)

Richard’s “sinensis” is very similar to Blyth’s, being best told by song, which is rarely heard in the Shanghai area. According to Per Alström et al., whose book Pipits and Wagtails is the authority on Palearctic and Nearctic pipits, the song of Blyth’s is “very characteristic and completely different from [that] of Richard’s” (242). During a trip in July 2015 to the Inner Mongolian prefecture of Hulunbeier, one of the few places in China where Blyth’s breeds, I recorded the song.

Blyth’s Pipit, flight song, recorded 22 July 2015 at a point (48.767866, 116.834183) near Hulun Lake, Inner Mongolia (2.1 MB; 00:32)

The calls of the two species also differ, but less markedly. The flight call of Richard’s is a common bird sound in Shanghai during migration season. The call of Blyth’s is similar enough to “cause problems even for some veteran observers” (Alström et al. 244). For Shanghai birders, even those unfamiliar with Blyth’s, a “Richard’s” with a strange flight call is worth your attention. Listen for what Alström et al. describe as a call “less harsh, softer and more nasal” than Richard’s (244). For reference, review the flight call of Richard’s:

Richard’s Pipit, flight call, Dishui Lake, Shanghai, February (00:01; 852 KB)

Regarding plumage, the most reliable differentiator of Richard’s and Blyth’s is the pattern of the median coverts. In Blyth’s, a typical adult-type median covert will show well-defined, squarish black centers. In Richard’s, the adult-type median coverts are less clear-cut, rufous-tinged, and triangular. Note that the fresher the plumage, the more reliable this differentiator is.

Another less reliable criterion is structure. Shanghai birders will agree that the first impression a non-“sinensis” Richard’s usually gives is “large pipit.” Other pipits, such as Buff-bellied Pipit, Red-throated Pipit, and Olive-backed Pipit, give a “small pipit” impression.

Richard's Pipit
Richard’s Pipit, Jiangsu, September. Alström et al. urge care in ID’ing Blyth’s and Richard’s. Here, the median coverts of this Richard’s appear squarish, like Blyth’s (bottom R, inset). But note the date of the photo: September, a time of year when most Richard’s show worn plumage. ‘In worn plumage,’ the authors write, ‘the shape of the dark centres to the secondary coverts is generally less obviously different, and the pale tips can be much the same colour in both species’ (237). The ID of this Richard’s was derived from its call, a more constant characteristic, and not from the appearance of its median coverts, a more variable characteristic. (Craig Brelsford)

Alström et al. say, and I having seen Blyth’s can concur, that a birder viewing Blyth’s will get a “small pipit” impression: “The smaller size, lighter build and shorter tail,” the authors write, “are often most apparent in flight, when [Blyth’s] often recalls one of the smaller pipits rather than Richard’s.” Note also that the smaller size and shorter bill, tail, and hind claw of Blyth’s give that species a “better proportioned” look than the larger and heavier Richard’s (237).

The directions above should be seen as guidelines; individual Richard’s and Blyth’s may defy easy categorization, “sinensis” Richard’s even more so. Alström et al. caution against jumping the gun with your ID: “It is crucial to realise that in both species (especially Richard’s) appearance can vary considerably in one and the same individual depending on mood, weather, etc.,” they write. “Also, some Richard’s are structurally very like Blyth’s; this is especially true of southern Chinese Richard’s (‘sinensis’)” (237).

A record of Blyth’s Pipit in Shanghai would shoot to the top of the “Year’s Best” list. The stakes are high, so look diligently, and use caution. Good luck!

The Case for Conserving Cape Nanhui

Editor’s note: This tranquil scene is from Iron Track (31.003613, 121.907883), home of Reed Parrotbill and dozens of other species, and part of the large reed beds on the Dazhi River at Cape Nanhui. In the face of manic development, and in spite of being under no protection, Cape Nanhui conserves the best reed beds on the Shanghai Peninsula as well as mudflats critical to tens of thousands of migrating shorebirds. To save these treasures, Shanghai people must act now.

Who will save Cape Nanhui? Not foreigners like me, but the people of Shanghai. We foreigners are numerous in Shanghai and are disproportionately represented among the birders here. We can offer valuable perspectives. But if the people of Shanghai themselves do not wish to ensure a bright natural future for Cape Nanhui, then there is little that anyone can do.

I think that the people of Shanghai are ready for real conservation on the Shanghai mainland. Basic conservationist ideas have broad appeal, and an easily accessible, world-class, “people’s wetland reserve” at Cape Nanhui is a basic conservationist idea.

If I were Chinese and were arguing for a people’s wetland reserve for Cape Nanhui, then I would bring to light the following points.

SHANGHAI IS NOT A CITY IN THE CONVENTIONAL SENSE

Shanghai Peninsula
The largest component of the city-province of Shanghai is the Shanghai Peninsula, a projection of land between the Yangtze River and Hangzhou Bay. Cape Nanhui is the tip of the peninsula, is a critically important stop for migrating birds, and is completely unprotected. A nature reserve at Cape Nanhui would form a third ‘stepping stone’ for birds crossing the mouth of the Yangtze, joining the reserves at Chongming Dongtan and Jiuduansha. (NASA/Craig Brelsford)

Shanghai “市” isn’t really a city or a “municipality,” as 市 is often translated. It is a city-province, accountable to no government but the national government. The city-province is vast, covering an area greater than the U.S. states of Delaware and Rhode Island. Shanghai is twice as big as Luxembourg, half as large as Northern Ireland, and a third the size of Wales.

From a conservationist’s perspective, it is important to view Shanghai as a province and not a city, because cities are not usually thought of as being responsible for maintaining large nature reserves within their borders. Provinces, by contrast, are large enough to accommodate nature reserves.

I propose that, where workable, we stop referring to Shanghai as a city or municipality and start applying to it the more accurate label of city-province.

SHANGHAI OCCUPIES LAND UNUSUALLY IMPORTANT TO CONSERVATION

Reed Parrotbill
Reed Parrotbill is a a symbol of Shanghai and candidate for Shanghai Provincial Bird. Nowhere do the people of Shanghai have a better chance of seeing this Near Threatened species than in the reed beds at Cape Nanhui. Protection of the reed beds at Cape Nanhui would send a message to the world that Shanghai takes conservation seriously. (Craig Brelsford)

Any jurisdiction covering an area the size of a small country would be expected to conserve substantial amounts of its area. In the case of Shanghai, the call to conserve is even louder, because the area it occupies is unusually important for conservation. The Shanghai Peninsula is situated between the mouth of Asia’s greatest river and Hangzhou Bay. It is on the East Asian-Australasian Flyway and attracts tens of thousands of passage migrants representing a few hundred species.

Cape Nanhui is the tip of the Shanghai Peninsula and attracts passage migrants and winter visitors such as the Endangered Black-faced Spoonbill. Its large reed beds are the final stronghold on the Shanghai Peninsula of Near Threatened Reed Parrotbill, a candidate for Shanghai Provincial Bird, as well as Near Threatened Marsh Grassbird.

sign

Cape Nanhui is completely unprotected; indeed, an attempt at a small wetland reserve has been shut down. The boardwalks and signs of the defunct reserve are crumbling, and the backhoes are standing by, waiting for the green light to smash what remains.

SHANGHAI, AN ENVIRONMENTAL UNDER-PERFORMER

No one is saying that Shanghai, a city-province of 26 million people, needs to create a Yellowstone. Any reasonable person understands the pressures the huge population of Shanghai puts on its natural resources.

Also, it must be pointed out that in the far-flung areas of the city-province, Shanghai has made an attempt at conservation. Chongming Dongtan preserves the eastern nub of Chongming Island, and Jiuduansha covers intertidal shoals near Pudong Airport.

Marsh Grassbird performing song flight at Cape Nanhui, 10 April 2016. The reed bed over which this grassbird was displaying is the largest at Cape Nanhui. It measures 1.4 sq. km and has its center at 30.876060, 121.945305. This reed bed is one of the last places on the Shanghai Peninsula where the song flight of Marsh Grassbird can be seen. (Craig Brelsford)

But Shanghai under-performs overall. Nowhere is the poor conservation performance more evident than in Pudong, the coastal city-within-a-city. Pudong is nearly double the size of Singapore and is half the size of Hong Kong. Yet the district contains zero wetland reserves on its mainland. Both Singapore and Hong Kong manage to hold in reserve significant portions of their territory.

The southeastern tip of Pudong is Cape Nanhui, a place that despite being under no protection still brims with natural treasures. No place on the Shanghai Peninsula has as many reed beds. The projection of land attracts birds making the long journey across Hangzhou Bay and the wide mouth of the Yangtze.

Moreover, Cape Nanhui is easily accessible to common people. It would be the perfect place for a world-class wetland reserve on the model of Sungei Buloh in Singapore and Yeyahu National Wetland Park in Beijing.

On shanghaibirding.com I have addressed the issue of conserving Nanhui:

Save the Nanhui Wetland Reserve! (cri de coeur plus call to action)
Remnants (preparation for probable demise of Cape Nanhui)
Reed Parrotbill, Symbol of Shanghai (naming Reed Parrotbill Provincial Bird of Shanghai will send a message about the importance of the reed beds such as those at Cape Nanhui)
Spoon-billed Sandpiper at Nanhui (proof of yet another endangered species using the defunct wetland reserve at Nanhui)
Will the Spoon Survive? (Nanhui is not the only area under threat. You ought to see the mess at Yangkou, Jiangsu. Conserving Nanhui will offset the losses elsewhere on the Chinese coast and will put a conservationist feather in Shanghai’s cap)
Meet Kai Pflug, Nanhui’s Mr. Clean (tribute to a birder doing his small part)

NEXT STEPS

We foreigners have had much to say about the future of Nanhui. I would like to hear more from Chinese. Is the case for a world-class wetland reserve at Nanhui convincing to you? If so, then what do you propose to do to bring it about?

First Mainland Shanghai Record of Hooded Crane

Editor’s note: The photo above shows Hooded Crane flying above fields at Nanhui on 12 Nov. 2016. Before our sighting, Grus monacha had never been recorded on the Shanghai Peninsula. Each year, about 100 Hooded Crane overwinter on eastern Chongming Island, 60 km north of Nanhui at the mouth of the Yangtze River.

Elaine Du and I birded three of the four days between Sat. 12 Nov. and Tues. 15 Nov. 2016. We noted 105 species. On Saturday we had the first-ever record in Nanhui of Hooded Crane. We also found Baikal Teal on Saturday as well as Greater White-fronted Goose, Tundra Swan, and Jack Snipe. Sunday was also spent at the coastal site in Pudong and gave us calling Brown-cheeked Rail as well as Hair-crested Drongo and late Rufous-tailed Robin. Other weekend Nanhui records were endangered Black-faced Spoonbill holding steady at the defunct nature reserve (30.920500, 121.973167), Amur Falcon feasting on gnats small enough for leaf warblers, an uncommon Shanghai record of Water Pipit, and two more sightings of endangered Yellow-breasted Bunting at its increasingly reliable site (30.850707, 121.863662). On Tuesday at Shanghai’s Zhongshan Park (31.221888, 121.420066) we had a very late Narcissus Flycatcher.

The flyby sighting of Hooded Crane was Elaine’s finest hour. Michael Grunwell was in the back seat and, blinded by the roof, would have never seen the crane. I was busy driving along a very uncertain dirt track. We see so many Grey Heron at Nanhui, and it is so easy to disregard them, and sure enough two of the three birds flying together were Grey Heron. But one was not, and Elaine caught it.

Elaine got her first pair of binoculars in 2013 and is now making big discoveries. “You’ve come a long way, baby!”

Thanks to Shanghai birder Xiao Cao for his knowledge of species histories in Shanghai. It was he who told us that our Hooded Crane was a first record for mainland Shanghai.

The area provides excellent habitat for Reed Parrotbill and wintering Chestnut-eared Bunting and Jack Snipe. The latter species was found 12 Nov. 2016 by our group. (Craig Brelsford)

The experience with Jack Snipe occurred Saturday near dark at Iron Track (31.003613, 121.907883). Our partner Michael Grunwell, Elaine, and I were looking for Brown-cheeked Rail. The snipe sneezed when flushed, flew to a towering height in a tighter formation than is typical in Common Snipe, and after all the fuss ended up landing only 150 m from where they had started.

When the snipe began their flight, I figured they were Common and continued looking for rails. Then I heard Michael cry out, “Possible Jack!” The snipe flew directly over us. The bill was noticeably shorter than the bill of the Common I have come to know. Elaine too saw the short bill.

The three of us feel confident in our record of Jack Snipe and urge others to be on the lookout for this species. Get pictures if you can.

Another look at Iron Track area, looking back toward the road.

Iron Track is part of the extensive reed-bed habitat lining the Dazhi River (大治河). It provides excellent habitat for Chinese Pond Heron, White-breasted Waterhen, Brown-cheeked Rail (and possibly Water Rail), wintering Bluethroat, and wintering Jack Snipe. Reed Parrotbill is resident.

The beds are on either side of the river, are unlikely to be developed, and are in good condition. They are a remnant of the habitat that used to cover the entire area.

ID’ING BROWN-CHEEKED RAIL ON CALL

On Sunday at Nanhui we positively identified 2 Brown-cheeked Rail on call. Here is the recording I made (00:28; 2.7 MB):

The pitch matches closely the pitch in the recordings by Anon Torimi of rails assigned to Rallus indicus. I downloaded Torimi’s recordings from xeno-canto.org. I invite Shanghai birders to do the same. Get to know the sounds of both R. indicus and the extralimital R. aquaticus and start adding these species to your own Shanghai lists.

AMUR FALCON CATCHING GNATS

On Saturday we were amazed to see Amur Falcon catching flies with their talons. We had five near Big Bend (31.000321, 121.938074). In top left of the three-panel photo above, the falcon has spotted its prey and is accelerating toward it. In bottom left, the gnat is visible as the falcon zeroes in. At right, the falcon raises its talons for its tiny prey.

The instinct to use its talons is inefficient in this case and shows that Amur Falcon has evolved to hunt larger game. Smaller aerialists such as swifts, nightjars, swallows, and flycatchers snatch up their prey directly with the mouth.

A NOTE FROM TOMMY PEDERSEN

Tommy Pedersen is a pilot with Emirates. He is Norwegian and has been based in Dubai for many years. An accomplished birder, Tommy created uaebirding.com. This outstanding site is the best introduction to birding in the United Arab Emirates and the Arabian Peninsula.

Tommy recently sent a message to shanghaibirding.com:

I had a work flight to Shanghai 9-11 November 2016, and following Craig’s excellent site, I decided to visit Nanhui.

I booked a room at Holiday Inn Express (no English spoken, cold and drafty rooms), close to the Magic Parking Lot and Nanhui Nature Reserve. Two targets: Saunders’s Gull and Reed Parrotbill.

On Day 1, 9 November, I was extremely lucky and bumped into Craig and Elaine with Erica, who took me to the nature reserve. We had a jolly good time (at least I was), and Saunders’s Gulls were soon spotted (http://ebird.org/ebird/view/checklist/S32503941).

Day 2 saw me walking 16 km in total, enjoying a near windless morning with massive migration overhead. It was magic: http://ebird.org/ebird/view/checklist/S32503940

Hope to be back soon

Coining the Term ‘Cape’ Nanhui

‘Cape Nanhui’ is the southeastern-most point of Pudong (red) and the city-province of Shanghai (yellow). The Shanghai Peninsula could be construed to be the mainland areas of Shanghai. (Wikipedia/Craig Brelsford)

Did you know that the birding area at Nanhui is a cape? This is an aspect of Nanhui that perhaps requires more discussion. The 30-km stretch of coastline is the southeastern-most point of Pudong as well as of the entire city-province of Shanghai.

Cape Nanhui (I like the ring of that) juts out between the mouth of the Yangtze River and Hangzhou Bay. The cape aspect of Nanhui makes it even more valuable to migrating birds than regular coastline. Nanhui is a stepping stone, catching birds that have just made a non-stop crossing of the mouth of the Yangtze River (in fall) or a non-stop crossing of Hangzhou Bay (in spring).

I also find it interesting that one never hears of the “Shanghai Peninsula.” It’s a term with explanatory power. Although rather nubby, the Shanghai Peninsula is clearly a promontory between the mouth of the Yangtze River and Hangzhou Bay. Cape Nanhui is the tip of the promontory.

If conservationists talk about a nature reserve for “Cape Nanhui,” the tip of the “Shanghai Peninsula,” then maybe they will have a stronger case.

Speaking of making a case: I saw the car with lettering saying “Pudong TV” and waved the journalists over. I told them I had something they might want to hear. Echoing my recent post Save Nanhui, I told the pair that Shanghai can have it all. Shanghai can be a world financial hub and China’s greatest metropolis and be a green city. It can follow Hong Kong and Singapore and develop a world-class urban wetland reserve easily accessible to nature lovers without their own car. Nanhui’s old wetland, I said, pointing to the defunct reserve behind us, could be the site of such a reserve.

As I talked, a small crowd gathered. Most seemed supportive of my ideas. I was not surprised. A world-class wetland at Nanhui is a basic conservationist idea, and basic conservationist ideas have broad appeal.

Yellow-breasted Bunting Leads Parade of Endangered Migrants at Cape Nanhui

Our partner Mike May got this image of a Yellow-breasted Bunting feeding on rice near Luchao. The endangered buntings were found at the spot we call the Marshy Agricultural Land (). On 5 Nov. 2016 we first found Yellow-breasted Bunting there. We returned on 8 Nov., when Mike got this shot, as well as 9 Nov., finding the species there each time.

Since last we posted, Elaine Du and I birded three days: Sat. 5 Nov., Tues. 8 Nov., and Wed. 9 Nov. 2016. We noted 115 species. At Cape Nanhui’s defunct nature reserve (30.920507, 121.973159) we had Long-billed Dowitcher and endangered Great Knot, and we noted the continued presence there of endangered Black-faced Spoonbill. Dishui Lake (30.908702, 121.945124) yielded Smew, Greater Scaup, Black-necked Grebe, and an uncommon Shanghai record of Black Kite. We had Reed Parrotbill and Brown-cheeked Rail at a new site called the Iron Track (31.003613, 121.907883), and we went three-for-three with endangered Yellow-breasted Bunting at a point (30.850707, 121.863662) north of Luchao, where we also attained an autumn record of Black-browed Reed Warbler. Drives along the sea-wall road gave us Amur Falcon and Peregrine Falcon, and Japanese Sparrowhawk dove for cover into Microforest 7.

We found Tundra Swan (bewickii) on all three days, with a high count of 11 on 9 Nov. on the mudflats near Big Bend (31.000321, 121.938074). The previous evening near Big Bend we had a rare Shanghai record of Greater White-fronted Goose. In the mudflats north of South Lock (30.860073, 121.909997) we had Eurasian Curlew and a rare Shanghai record of Mew Gull Larus canus.

Among shorebirds, Dunlin and Kentish Plover not surprisingly were the most numerous. Careful scanning allowed us to sift out more southerly winterers such as the Great Knot as well as small numbers of Black-tailed Godwit, Broad-billed Sandpiper, Red-necked Stint, and Sanderling. Vulnerable Saunders’s Gull were at the defunct nature reserve.

Microforest 4 yielded Japanese Robin on 7 Nov., seen and photographed by Shanghai birder kaca. A careful search by us the following two days failed to turn up the rare passage migrant. On 5 Nov. we had a late record of Arctic Warbler. Other interesting passerines were Hair-crested Drongo and Naumann’s Thrush. Scaly-breasted Munia was at the Iron Track, we had season’s first Rustic Bunting, and the skies gave us Red-rumped Swallow and Asian House Martin.

On 5 Nov. Elaine and I were joined by Michael Grunwell, the Shanghai-based veteran British birder. On 8 Nov. we welcomed U.K. birder Mike May, and on 9 Nov. we partnered with U.S. birder Erica Locke.

On 8 Nov. we found a bird photographer with a cage baited with mealworms. We asked him politely but firmly to put the cage away, and he complied.
