Walking or driving at Cape Nanhui these days, you may hear an interesting sound coming from the reeds. HBW describes it as “a low-pitched, repeated djuk-djuk-djuk,” but I do not think that description does the sound justice. To me, the sound is reminiscent of some of the more obscure Cure songs, in particular, “Like Cockatoos”—the same swirling sound. This is the sound of Marsh Grassbird.

It is much more difficult to see than hear Marsh Grassbird. It took me a few days before I was successful (with the help of 吴世嘉 and David—thanks!). The bird usually hides deep in the reeds. Occasionally, and in particular this time of year, it flies up a few meters while singing before dropping quickly back into the reeds.

What does Helopsaltes pryeri look like? Just look at the photos below, and consider the Chinese name, Banbei Daweiying (斑背大尾莺, “striped-back long-tailed warbler”). The mainland Asian breeder, sinensis, is 14 cm long and weighs 10 g. It feeds mainly on insects and breeds in wet, reedy swamps.

Its most remarkable feature is its song display. The grassbird begins singing on a reed, flies, still singing, in a high arc, then drops back quickly into the reeds (usually too quick to get a decent photo, at least for me).

The species is still a mystery to ornithologists, with uncertainties regarding its migration patterns, for example. Living a life hidden in the reeds does not facilitate ornithological studies.

The conservation status of Marsh Grassbird is Near Threatened. It is suffering from habitat loss as the reed beds it needs for breeding are being destroyed. At Cape Nanhui alone, my guess is that in the past year around a third of the habitat suitable for the species has been destroyed. With an estimated (declining) global population of 10,000 to 15,000 individuals, the last thing the species needs is further destruction of the reeds at Nanhui.

Is Marsh Grassbird a spectacular-looking bird? Perhaps not, but human standards of beauty are not a criterion for conservation. If however you need a reason to protect this bird, then just listen to its song:

Here are some of my recent photos of the threatened bird, all taken at Cape Nanhui:

‘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.

The eBird list for Pudong Nanhui Dongtan Wetland. Submit your records! It’s fun!

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 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.
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.

Helopsaltes ocustella 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:

The plight of Marsh Grassbird brings to mind the series of posts I wrote last year on the precarious environmental situation at Cape Nanhui.

Where the World’s Greatest Flyway Meets the World’s Greatest City

Finally, it is ready: Elaine’s and my report on the doings of this past spring in Shanghai. We’re calling it “Shanghai-area Springtime Birding, 2016.”

The report is the latest in a growing list of resources available on shanghaibirding.com. Everything we do here is geared toward showing you what birding is like at the point on the Earth where the world’s greatest migratory flyway meets the world’s greatest city.

The report covers 7 March to 24 May 2016. Elaine and I birded 38 of those 79 days and noted 240 species. We partnered with members of our network of subscribers and contributors to shanghaibirding.com. Special thanks to Michael Grunwell and Jan-Erik Nilsén as well as to Xueping Popp, Stephan Popp, Kai Pflug, and Ian Davies.

Why should you read “Shanghai-area Springtime Birding, 2016”? Read it to plan your own explorations and to get an idea of what birds you can expect to see in this city in March, April, and May. You’ll find no more complete a report on that subject, anywhere.

From the intro:

“We deepened our knowledge of the birds of the East Asian–Australasian Flyway and increased our understanding of the pressures these birds face in the Shanghai region. One of the most densely populated areas in the world and an economic dynamo, the Shanghai tri-province area encompasses Shanghai, Jiangsu, and Zhejiang, is the size of the U.S. state of Kansas, and has a population of 160 million–half that of the United States.”

From the highlights:

“ — We continued to monitor species under threat by the uncontrolled coastal development afflicting the region, among them the endangered Black-faced Spoonbill, Great Knot, and Yellow-breasted Bunting; near-threatened Eurasian Oystercatcher, Asian Dowitcher, Black-tailed Godwit, Bar-tailed Godwit, Eurasian Curlew, Grey-tailed Tattler, Red Knot, Curlew Sandpiper, Japanese Paradise Flycatcher, Marsh Grassbird, and Reed Parrotbill; and vulnerable Chinese Egret, Saunders’s Gull, and Yellow Bunting. We led a group one of whose members found the critically endangered Spoon-billed Sandpiper.

“ — We recorded the first Blue Whistling Thrush in Shanghai since 1987. Other interesting finds were Horned Grebe on Chongming, Oriental Plover on Hengsha Island, Ruddy Kingfisher at Yangkou, Red-throated Thrush at Century Park, singing Sakhalin Leaf Warbler at Zhongshan Park, Grey-crowned Warbler, Two-barred Warbler, Pechora Pipit, and Citrine Wagtail at Nanhui, White-shouldered Starling on Lesser Yangshan, Rufous-faced Warbler at Nanhui and on Lesser Yangshan, and Bluethroat at Nanhui and on Chongming.”

Asian Dowitcher Leads Shanghai Spring-Mig Birding Pageant!

On 21-24 April 2016, teaming up with Jan-Erik Nilsén and Michael Grunwell, Elaine Du and I noted 110 species. Our birding ranged from the inner city of Shanghai (Zhongshan Park, Century Park) to the coast at Cape Nanhui. The highlight of this spring-mig bird pageant was Asian Dowitcher at Nanhui. The dowitcher was in a pool that also held 11 Chinese Egret. Nanhui also gave us endangered Black-faced Spoonbill, Far Eastern Curlew, and Great Knot and near-threatened Red Knot and Curlew Sandpiper. Among the other uncommon to scarce passage migrants were 4 Greater Sand Plover, 2 Pechora Pipit, 4 Brown-headed Thrush, 2 Siberian Blue Robin, 3 Siberian Rubythroat, and Citrine Wagtail. Joining them were 5 Terek Sandpiper, 3 Temminck’s Stint, 12 Long-toed Stint, 3 Eurasian Wryneck, 2 Eastern Crowned Warbler, 4 Japanese Thrush, 2 Eyebrowed Thrush, Mugimaki Flycatcher, 2 Blue-and-white Flycatcher, macronyx Eastern Yellow Wagtail, and 3 Tristram’s Bunting. We had impressive numbers (ca. 3180) of Barn Swallow, and picking through the clouds of hirundines we coaxed out 3 Pale/Sand Martin and 4 Red-rumped Swallow. Near-threatened Marsh Grassbird were singing in the reed bed at 30.866006, 121.939614. Near the grassbirds were Brown Crake, Reed Parrotbill, and Oriental Reed Warbler. A quick trip to Zhongshan Park on Thursday netted Narcissus Flycatcher and Yellow-rumped Flycatcher, and at Century Park on Friday we had Indian Cuckoo.

A Swede based in Beijing, Jan-Erik is an experienced birder and a friend. I have partnered with Jan-Erik in Qinghai (2014) and in Hulunbeier, Inner Mongolia (2015). Last year he introduced me to the Beijing-area birding hot spots.

Among Jan-Erik’s many strengths is his ear. When the rain finally let up on Sunday, Jan-Erik and I were walking between microforests on the Nanhui sea wall. “Pechora Pipit!” Jan-Erik cried. On a windy day, Jan-Erik’s sensitive ear had detected the hard, clicking call of a distant Pechora. I missed this one, but my adrenaline was running, and I ran back to our rented Buick, driven by Elaine. I put together my 600 mm lens and Nikon D3S, which had lain dormant throughout the rainy Saturday and Sunday morning. “Record-shot time!” I said to my wife. Almost as soon as I had set up my camera, I found another Pechora atop a tree. I had not seen Pechora Pipit since 2010. Jan-Erik’s strong hearing skills made the rare view possible.

The teamwork continued later that day. At the dowitcher spot (30.877779, 121.955465), Elaine, using the spotting scope and scanning the pond below us, cried out, “Dowitcher! Maybe Asian!” Elaine had never seen Asian Dowitcher, but Michael Grunwell’s fascination with this bird had prepared Elaine for the possibility of encountering the species. Jan-Erik and I ran back, and I enjoyed my first-ever views of the near-threatened species. Great spot, Elaine!

Jan-Erik arrived late Thursday night. On Friday we did light birding at Century, noting 29 species. On Saturday and Sunday I had the pleasure of introducing Jan-Erik to Nanhui. We noted 99 species over the weekend, and we had the added pleasure of having Michael Grunwell join us Saturday. Despite the rain, I have rarely been happier birding than I was Saturday, for on that day the two birders who have taught me the most were finally in the same car together. Michael is a British birder who has been living in Shanghai since last year.

The bad weather kept us off Lesser Yangshan Island and dashed our hopes of visiting Hengsha Island. As darkness fell Saturday, we drove Michael to the Dishui Lake Metro Station. Jan-Erik, Elaine, and I spent the night at the Holiday Inn at Nanhui. This proved to be a good move, for staying at Nanhui saved me a 90-km drive back to the city after an exhausting day and put us in position for an early start Sunday. A sea-view room cost 500 yuan, money we considered well-invested.

Oriental Plover Highlight 103-Species Weekend

On Sat. 9 April and Sun. 10 April 2016, Elaine Du and I noted 103 species at three Shanghai-area birding hot spots. We had Oriental Plover and Black-faced Spoonbill on Hengsha, the latter present also at Cape Nanhui, where we found in addition Brown Crake, Greater Sand Plover, Black-tailed Godwit, Marsh Grassbird, Bluethroat, and Citrine Wagtail. Lesser Yangshan yielded out-of-range Rufous-faced Warbler and our season’s first flycatcher, Asian Brown Flycatcher. Other season’s firsts were Eurasian Wryneck and Oriental Reed Warbler on Hengsha, Oriental Pratincole, Japanese Thrush, Tristram’s Bunting, and Meadow Bunting on Lesser Yangshan, and Broad-billed Sandpiper at Nanhui. Garganey and singing Brown-flanked Bush Warbler were on Hengsha and Temminck’s Stint and Grey-backed Thrush were noted at Nanhui. Red-throated Pipit were on Hengsha and Nanhui, as were Intermediate Egret, “SwintailSnipe, Reed Parrotbill, and Chestnut-eared Bunting.

On Sat. 9 April Elaine and I birded Hengsha, the alluvial island at the mouth of the Yangtze. Our target was Oriental Plover Charadrius veredus, which we found after a short search. Oriental Plover breeds in deserts and steppes mainly in Mongolia, and in China in Hulunbeier, Inner Mongolia. For Elaine, Ori Pluv was a virtual lifer, as her only previous experience with the species was our quick, long-distance look at an individual near Hulun Lake last July.

It is spring and Meadow Bunting are staking out territories on Lesser Yangshan. This aggressive little fellow had attracted the attention of a female, which kept to the undergrowth while he roared. Common on Lesser Yangshan, Emberiza cioides is almost never recorded on the nearby coast.

On Sun. 10 April Elaine and I were joined by Shanghai-based British birder Michael Grunwell. We noted 90 species on Lesser Yangshan Island and at Nanhui.

The three of us found 30 singing Marsh Grassbird in the large reed bed at 30.866006, 121.939614, a point 2.8 km south of the lock at Nanhui and 4.1 km south of the Magic Parking Lot/Holiday Inn (30.882784, 121.972782). An unpaved road leads into the marsh. The grassbirds were noted only in that reed bed and not in other seemingly suitable reed beds elsewhere at Nanhui. The grassbirds were using only those parts of the reed bed far from the road. They were making their curving display flight.

Marsh Grassbird is also known as Japanese Swamp Warbler and Japanese Marsh Warbler. It is listed as Near Threatened by the IUCN. The IUCN notes that Marsh Grassbird is “very sensitive to habitat structure and does not tolerate vegetation that is too short or too tall.” It is threatened mainly by the conversion of its wetland habitat to other uses.

Speaking of conversions, new construction is changing all three of the birding spots we visited last weekend. The transformation at Nanhui has been noted by me here and here. Lesser Yangshan Island is being converted from an island to an even bigger megaport, and Garbage Dump Coastal Plain (30.638860, 122.060089) is steadily growing unbirdable. A bright spot on Lesser Yangshan is the new wetland (30.611902, 122.114873) on reclaimed land between Lesser Yangshan and Dazhitou Island.

Will this 100-hectare plantation of trees add a new dimension to birding on Hengsha?
Will this 100-hectare plantation of trees add a new dimension to birding on Hengsha? (Craig Brelsford)

In the reclaimed area on Hengsha, a 100-hectare area at 31.299495, 121.893845 is being converted from savanna to forest. That is an area about two-thirds the size of Century Park in Pudong. This may be good news, as the tree plantation may attract forest species such as flycatchers and leaf warblers, families that on the formerly treeless reclaimed area at Hengsha have always been scarce.

The springtime birding season in Shanghai is really picking up steam. On the Web site of the Shanghai Wild Bird Society, shwbs.org, birders have recently reported Long-billed Dowitcher, Asian Dowitcher, and Ruff on Chongming and Spoon-billed Sandpiper and Black Redstart on Hengsha.
