GUEST POST: Well-spotted in the Bamboo, by John MacKinnon

Editor’s note: John MacKinnon is co-author of A Field Guide to the Birds of China, the most influential book ever written about the birds of China. John also authored the first and second guest posts in the history of shanghaibirding.com, and he visited Shanghai’s Cape Nanhui with me in April 2017. Herewith we present “Well-spotted in the Bamboo,” John’s third guest post for our site. In it, John introduces the bird community of Jinfoshan, the highest peak in the Dalou Mountains in the city-province of Chongqing. John’s bird of the trip was Spotted Laughingthrush (above), a “quiet, gentle bird” of mountain forests and one of seven species of laughingthrush at Jinfoshan. — Craig Brelsford

I recently was invited to join a workshop of the China Bird Watching Association to review three years’ monitoring of wintering data on Scaly-sided Merganser. The attraction was that the meeting was to be held in Jinfoshan National Nature Reserve in Nanchuan District, Chongqing. So I added a day to my trip for birdwatching and ended up on the top of this spectacular mountain for three days. Whilst floods were raging in Hubei and Anhui, we 40 birdwatchers enjoyed beautiful weather–blue skies and only occasional quick showers of rain to liven up the bird life.

At an elevation of 2251 m (7,385 ft.), Jinfoshan is the highest peak in the Dalou Mountains. The reserve was recently added to the South China Karst World Heritage Site. It is also listed as an important bird area on account of its having Reeves’s Pheasant. Jinfoshan combines ease of access with great birding trails and pristine habitats. It deserves much more attention, but it is not well-known to most birders.

Jinfoshan offers a great chance to view vertical stratification of flora and fauna, since you rise quickly–at first by shuttle bus and then by cable car through the subtropical evergreen valleys, temperate mixed forests, and finally subalpine forest and meadows.

I did not have time to explore the lower levels, but even whilst waiting for the shuttle bus we could see Red-billed Blue Magpie, Hair-crested Drongo, Blue Whistling Thrush, Russet Sparrow, and Plumbeous Water Redstart. Overhead circled Crested Honey Buzzard.

Our meetings were in a fancy five-star hotel. My own room had a bath big enough to swim in! But the real attraction was to get out into the surrounding forest whenever the meeting schedule gave us a chance.

Not that the meeting was not interesting in itself! I was impressed to see so many motivated and very professional presentations by the various monitoring teams. More rivers and reservoirs get monitored each year, and more than 1,000 wintering Scaly-sided Merganser were recorded in the winter of 2016-17. The Association has also done a magnificent job in developing the species as a lovable and charismatic emblem of conservation in China.

Even from the hotel windows and gardens there were plenty of birds to see. Olive-backed Pipit and White Wagtail were nesting on the grassy flat roof, and Verditer Flycatcher perched temptingly on prominent perches (though proved skittish for photography). The woods echoed to the calls of Large-billed Leaf Warbler and Bianchi’s Warbler. Green-backed Tit were in full breeding plumage; White-collared Yuhina was the most visible bird. The most beautiful of the common birds was certainly Vinaceous Rosefinch, the males of which were gorgeous in their deep purple plumage.

The cable-car ride offered amazing views of the deep gorges and lush forests. Great flocks of swifts circled their nesting sites on the sheer limestone cliff faces. In fact, these were mixed flocks, with Pacific Swift, House Swift, Himalayan Swiftlet, and Asian House Martin all visible.

Enter the woods and you meet a different complex of birds. The undergrowth is thick with bamboo, and indeed this site was historically within the range of Giant Panda and may again be considered as a site for reintroduction.

A rustling in the trees revealed feeding White-bellied Green Pigeon. Busily collecting moths and other insects were Red-tailed Minla, whilst the Blue-winged Minla were more leisurely preening each other after a morning bath. Black-headed Sibia sneaked in and out to collect small fruits. Flocks of Grey-hooded Fulvetta rattled alarm in the bamboo in mixed flocks with Rufous-capped Babbler and some very pretty Black-throated Parrotbill.

Whilst colleagues at the merganser meeting swarmed the site with an array of expensive cameras and optics, I stayed deep in the forests, looking for laughingthrushes. I was jealous of the others getting nice photos of Slaty Bunting and White-bellied Redstart, but I had my own rewards in the damp bamboo.

One of the most extraordinary bird calls consists of many dozens of high-pitched notes merging together into a prolonged whistle. The entire call lasts almost a minute, but the caller is elusive. Finally I nailed it down and photographed the caller in the act–an elusive Yellow-bellied Bush Warbler.

Another bird making loud and rather melodious calls was Red-billed Leiothrix working their way among the undergrowth collecting food for their nearby nestlings. Chinese Babax sneaked about on the forest floor.

Jinfoshan boasts seven species of laughingthrush. The lower sectors are home to White-browed Laughingthrush, Moustached Laughingthrush, and White-throated Laughingthrush. Near the reserve summit in open scrub and in the forested limestone forests, the common Elliot’s Laughingthrush creeps about, making low, quiet glides and gentle calls.

For me the highlight of the trip was meeting flocks of rather approachable Spotted Laughingthrush–a species with a much more restricted China distribution, being a Himalayan species extending in mountain forests as far as Jinfoshan and Shennongjia. This is a quiet, gentle bird, hopping about on the forest floor searching under leaves and through the moss.

‘Whilst colleagues … swarmed the site with an array of expensive cameras and optics,’ MacKinnon writes, ‘I stayed deep in the forests, looking for laughingthrushes. … I had my own rewards in the damp bamboo.’ Here is MacKinnon’s biggest reward: close views of the gorgeously patterned Spotted Laughingthrush. (John MacKinnon)

I sat among fluffy rock squirrels and watched their antics. They took me back to my favoured sites with warm memories of being among the Giant Panda of Wolong in Sichuan and the hilly forests of Bhutan.

GUEST POST: Let the Birding Gen Flow, by Michael Grunwell

Editor’s note: Michael Grunwell (above) is a British birder who last month moved from Shanghai to Penang, Malaysia. Michael spent four years in China, two in Nanchang and two in Shanghai. During that time, amid a full-time career and while providing for his wife and three children, Michael noted more than 700 species of bird in the Middle Kingdom. As if his personal commitments were not challenging enough, Michael faced another obstacle: a lack of “gen,” or basic birding information. In this essay, Michael contends that in China, getting gen is too difficult. Among “people in the know,” writes Michael, a “cheery, clubbable atmosphere” stifles the free flow of information. “China needs a great deal more published articles on sites and species,” he maintains, and he looks forward to a day when birding info in China will be “logged by and accessible to all.” — Craig Brelsford

Let the Birding Gen Flow
© 2017 by Michael Grunwell
for shanghaibirding.com

Exactly 33 years ago, I went on an independent birding trip to Peru. We faced Maoist insurrection and genuine danger–and we had better gen on where to find birds than China has in 2017.

China needs a great deal more published articles on sites and species. It is not right that most of the birding days in various bird-rich parts of China are unpublished and unavailable.

There seems to be a cheery, clubbable atmosphere which stifles real gen.

Take Sichuan, for example. Most Western birders on a trip to that province are taken to major sites such as Labahe and Balangshan. Very little precise gen is ever published about where species are seen.

Glowing accounts of yet another glorious China trip are written up by the tour companies and uploaded to Cloudbirders. These so-called “reports” are devoid of precise gen and should be seen for what they really are, which is infomercials.

With the growing popularity of bird-observation sites such as eBird, it has never been easier to make records that are timely, accurate, and most important, public. I note that the vast majority of the eBird hotspots in Sichuan have lists posted by independent birders–and almost no tour companies.

I do not agree that freedom of information damages commercial guiding. Take Turkey, for example. Although the main birding sites in that country are well-known, birders still pay big money for tours, because most people who go on tours are not list-obsessed but just normal people who want a hassle-free trip. I published a report on sites around Istanbul 13 years ago; a few years ago, I saw an advert for a bird tour going to the same places for a handsome price.

Another example is Sri Lanka. All the sites for the endemics are well-known. I recorded all the endemics in only five and a half days in 2011, and I wrote a full report that did wonders for my guide’s business.

Other examples are Florida, Arizona, The GambiaMajorca, and even my home country, the United Kingdom. In all these cases, there is more than enough accurate, precise gen amid a thriving bird-tour industry.

In stark contrast to the foregoing stands China. It still astonishes me that, time and time again during my four years in China, I had to rely on a handful of trip reports for basic gen. China has a population of 1.4 billion, and there is no simple, clear Web site giving basic information on the Top 10 birding sites in western China!

I want every day’s birding in China to be logged by and accessible to all. Am I idealistic? Indeed I am. Knowledge about Chinese birds needs to grow, and fast. We must escape the current sclerotic situation, in which keen birders are waiting for crumbs to be thrown from the table of those in the know.

If you want an example of what the future could be like, then look no further than this Web site, shanghaibirding.com. Craig Brelsford is committed to cooperative birding, providing complete and precise details of bird sightings and birding locations. On Shanghai Birding, the companion WeChat group, Craig and other users regularly post news of and directions to sightings within minutes of discovery.

That’s the way it should be–a birding culture dedicated not to the profits of the commercial birder but to the enjoyment of the common birder. A healthy birding community is run by common birders and for common birders.

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, loud–Taiga 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 of Craig Brelsford's recording of Kamchatka Leaf Warbler Phylloscopus examinandus.

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.

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 and the man who has taught me more than anyone about birding, 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.

Per's map of Arctic-type warblers.
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 by Craig Brelsford.
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 Cape Nanhui at the height of the spring migration left Mike May open-mouthed. Should anyone be surprised? The southeastern-most 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, transforming critical reed-bed and marshland habitat into an artificial forest. Looming in the background is the brand-new satellite city, Lingang. Nanhui, Shanghai, 26 March 2015.
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 being actively destroyed.

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.

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.

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 126 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.

You can join Shanghai Birding. Just friend me on WeChat (WeChat ID: craigbrelsford). Let me know that you want to join Shanghai Birding. I will add you.

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.
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.

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.
