Black-throated Loon and Red-throated Loon have been found at a little-birded recreational area in Pudong, and Slaty-backed Gull has appeared on the Huangpu River across from the Bund. All three species are rare in Earth’s Greatest City, with Black-throated Loon the scarcest. All three were brought to light by Shanghai birders using social media.
The loons had been sighted numerous times before my partner Michael Grunwell and I arrived on Sat. 18 March 2017 at Sanjiagang Seaside Park (31.217928, 121.768172). The dilapidated recreation area is on the coast of the East China Sea, near the mouth of the Yangtze River, 9 km north of Pudong Airport. Chinese birders discovered the loons, and birder Larry Chen, his partners Komatsu Yasuhiko and Archie Jiang, and bird photographer Kai Pflug followed up, reporting back to our chat group, Shanghai Birding.
On Sun. 19 March, the Red-throated Loon was discovered dead at the park by local birder Suōyǔ Hè (蓑羽鹤). It is not clear what killed the bird, but it may have slowly poisoned itself by ingesting oil that had collected on its feathers. Larry said that during his encounters with the individual “The loon was constantly attempting to preen itself” and that he clearly saw oil on one of its flanks. Can you detect anything amiss in the video below?
Red-throated Loon breeds at latitudes above 50 degrees in Eurasia and North America. Wintering Gavia stellata is more common in Shanghai than Black-throated Loon, being recorded annually here. Michael, my wife Elaine Du, and I found Red-throated Loon at Cape Nanhui in January 2016.
Black-throated Loon is also known as Black-throated Diver and Arctic Loon. Gavia arctica breeds across northern Eurasia and into Alaska. It is an uncommon winter visitor all along the coast of China and is very rarely noted in Shanghai, with the last previous record in 2012. Before the encounter Saturday, I had seen Black-throated Loon only once, on 18 Sept. 2013 at Laotieshan (38.730483, 121.134018) in the northeastern province of Liaoning.
Here is video of Black-throated Loon at Sanjiagang Seaside Park.
“I think we’ve found Slaty-backed!” Michael cried.
With my iPhone I took photos of the gull through my scope and uploaded the photos to Shanghai Birding, the chat group I manage on the instant-messaging application WeChat. Within minutes the experts in my pocket started weighing in. Shenzhen birder Jonathan Martinez and Larry Chen, both strong gullers, confirmed Michael’s ID. Michael and I had a life bird!
Slaty-backed Gull Larus schistisagus breeds on islands and cliffs on the coast of the Russian Far East (particularly the Kamchatka Peninsula) as well as Hokkaido. Wintering Slaty-backed are common in Japan, less common in northern coastal China, and rare in Shanghai.

On 18 Dec. 2016, a quartet of teenage birders found an acrocephalid in the Magic Parking Lot at Cape Nanhui, the nubby promontory in Pudong and Shanghai’s best birding hotspot. The consensus is that the bird is either Paddyfield WarblerAcrocephalus agricola or Manchurian Reed WarblerA. tangorum.
In the images below, note the supercilium, which extends behind the eye; dark eye-line; bright white chin and throat; peach breast band and flanks; bill with black upper mandible and pink lower mandible; and peaked head. Those criteria most closely indicate Manchurian Reed Warbler and Paddyfield Warbler.
Paddyfield Warbler winters mainly in India and would be extralimital here; Manchurian Reed Warbler breeds in northeastern China, is listed as Vulnerable and is therefore scarce, and probably passes through Shanghai.
Congratulations to Andy Lee, Komatsu Yasuhiko, Larry Chen, and Archie Jiang for this great Shanghai record.
On Thurs. 15 Dec. 2016 at Cape Nanhui, my wife Elaine Du and I did an interview with Pudong TV in Chinese. The segment will last five minutes and be aired later this month. In the interview I lamented the losses at Nanhui and spoke glowingly of the possibilities.
Meanwhile, John MacKinnon, co-author of the most famous bird guide in the history of China and author of a recent post for shanghaibirding.com, has expressed interest in the establishment of an easily accessible, world-class wetland reserve at Cape Nanhui.
MacKinnon asked me for the reasoning behind a wetland reserve at Cape Nanhui. I wrote the following:
THE CASE FOR AN EASILY ACCESSIBLE, WORLD-CLASS WETLAND RESERVE AT CAPE NANHUI, PUDONG, SHANGHAI
(1) Cape Nanhui is of extraordinary environmental importance. The tip of the Shanghai Peninsula between the Yangtze River and Hangzhou Bay, Cape Nanhui is a stepping stone for birds migrating across those bodies of water. Cape Nanhui also holds large reed beds, habitat critical to Reed Parrotbill, Marsh Grassbird, and other species at risk.
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.
The 2 Red-crowned Crane seen on Sat. 10 Dec. 2016 were the latest in a parade of endangered birds that I and other birders have noted at the Cape over the years. Critically Endangered Spoon-billed Sandpiper uses Cape Nanhui, as does Endangered Nordmann’s Greenshank. Around 2 percent of the world’s Endangered Black-faced Spoonbill are dependent on Cape Nanhui for several months each year. Large reed beds remain at Cape Nanhui and are the final strongholds on the Shanghai Peninsula of Near Threatened Marsh Grassbird and Near Threatened Reed Parrotbill. The latter species, a candidate for Shanghai Provincial Bird, will virtually disappear from mainland Shanghai if the reed beds at Nanhui are destroyed.
(2) Shanghai is clearly under-performing on the conservationist front. More must be done, and a good place to begin is Cape Nanhui.
Nature reserves have been established only on the extreme fringes of the city-province (which is a third the size of Wales). There are no reserves in mainland Pudong, a giant coastal district nearly twice the size of Singapore. Nowhere in this megalopolis can residents without a car enjoy the natural side of Shanghai, a city with an extraordinarily rich natural heritage. There is no known plan to conserve any of the dozens of square kilometers of reclaimed land on Hengsha.
(3) Because it is in the back yard of Shanghai, a city-province of more than 25 million people, a well-run, easily accessible wetland reserve at Cape Nanhui could be the match to light the fire of conservation across all China.
Hundreds of thousands of middle-class children could visit the reserve with their parents using nothing more than the Metro and a quick taxi ride and be sleeping in their own bed that night, dreaming about the wild birds they had seen that day. For millions of parents and their kids, the weekend could be “Saturday, Disney; Sunday, Cape Nanhui Wetland.” A day at a Cape Nanhui Wetland would be an early introduction to the glories of natural Shanghai and would foster an appreciation of the natural world.
If Shanghai can be a world economic center and have world-class airports and a world-class skyline and world-class entertainment such as Disney, then it can and must have an easily accessible, world-class reserve protecting its priceless coastline, reed beds, and migratory birds.
A world-class, easily accessible, wetland nature reserve at Cape Nanhui would become a mecca for birders and achieve world renown, as has been the case with similar reserves such as Mai Po at Hong Kong and Sungei Buloh in Singapore.
A male Narcissus Flycatcher made a rare late-autumn Shanghai appearance in Zhongshan Park (31.221888, 121.420066). On Tues. 15 Nov. 2016, the spectacle attracted 30 photographers.
The flycatcher was attracted by mealworms speared by photographers onto a soft steel wire. The wire was hung from a branch, enticing the flycatcher to hover to snatch the bait. The bird was appearing every 10 minutes.
I expressed concern but did not feel the need to be critical or intervene. The photographers obviously liked the flycatcher, did not think that they were harming it, and were enjoying themselves immensely.
I watched the flycatcher attack the mealworms. I think it unlikely that the wire would harm the bird. The bigger problem may be that the free protein will keep the bird here an unnaturally long time. A passage migrant through Earth’s largest city, Narcissus Flycatcher should be in Borneo by now.
Found at Cape Nanhui on Wed. 19 Oct. 2016: Pomarine Skua (called Pomarine Jaeger in North America). This first record for Shanghai was discovered by local birder Hé Xīn (何鑫) in the defunct nature reserve 1.4 km inland from the East China Sea. Kai Pflug was also on hand. Hé Xīn and Kai spread the news through our Shanghai Birding WeChat group, and the next day Elaine Du and I found the skua at the same spot (30.921625, 121.958940). The skua stayed four days, until Sat. 22 Oct.
The seabird appeared healthy, alternately feeding, preening, and roosting. Its plumage was shiny, and I saw no evidence of injury. It was a healthy refugee blown west by Typhoon Haima.
As sightings of skuas on the Chinese coast are rare, and because skuas have a bewildering array of plumages, at first there was some confusion about the species of our bird. It soon became clear that the vagrant was either Pomarine Skua Stercorarius pomarinus or Arctic Skua (IOC: Parasitic Jaeger) S. parasiticus. But which?
POMARINE ID BASICS
To answer that question, we needed photos, and so on Thurs. 20 Oct. Elaine and I drove to Cape Nanhui, the coastal birding site in Pudong.
We quickly found and photographed the bird. After examining our images, talking to other birders, and studying the books, we determined that it is a pale-morph adult pomarinus in non-breeding plumage. Here’s why:
— S. pomarinus is larger and bulkier than the other jaegers (small skuas), in particular the jaeger that it most resembles, S. parasiticus. The jaeger we found was large and bulky.
National Geographic describes pomarinus as a “bulky brute with a commanding presence [and a] thick bull-neck—a Rottweiler among the jaegers.” S. pomarinus, Geographic adds, “is the bulkiest [jaeger] and appears pot-bellied and very deep at the chest. … Often it appears there is more body before the wing than behind the wing.”
The image above is in line with that description. Below, another image illustrating the bulky shape and barrel chest.
— In adult pale-morph pomarinus, the black helmet reaches below the gape, and black plumage surrounds the base of the bill. Most pale-morph parasiticus show a white spot at the base of the upper mandible and a less-extensive helmet that does not reach below the gape.
Below, another close-up of the head. Note here and above that, unusually for pomarinus, the bill appears almost all-black.
— Adult pale-morph pomarinus is more heavily barred than parasiticus. Most adult pale-morph pomarinus show a coarse breast band and dark barring on the flanks. Most adult pale-morph parasiticus show a diffuse greyish-brown breast band and lack barring on the flanks.
There are several other ID points, some of them, such as tail streamers, not visible in The Shanghai Skua. The points discussed above, however, are enough, we think, to clinch the ID.
Enjoy these other photos of the rarity.
The skua was very tame and performed various functions in its unaccustomed surroundings. It scratched itself (below), bathed, scavenged dead fish, and occasionally took short flights.
Its most common activity was roosting on the mud bank.
Kai Pflug got the photo below of the skua with wings upraised. Note the unbarred underwing and pale flash at the base of the primaries, further evidence that the skua is an adult.
Hé Xīn (below) found The Shanghai Skua on Wed. 19 Oct. 2016, a historic first record for Shanghai. The next day I met Hé Xīn at the site.
RARE AUTUMN RECORD OF NARCISSUS FLYCATCHER
On Thurs. 20 Oct. and Sun. 23 Oct. 2016, Elaine Du and I birded Nanhui and the sod farm south of Pudong Airport (31.112586, 121.824742). On 23 Oct. Elaine and I were joined by British birder Michael Grunwell. The two days yielded 92 species. After the Pomarine Jaeger, the big news was rare autumn sightings of Narcissus Flycatcher, another record of Nordmann’s Greenshank, and still more evidence that the highly threatened Nanhui wetland is much depended on by Black-faced Spoonbill.
On 20 Oct. in the canal at the base of the sea wall at Nanhui, Elaine and I had 18 Mandarin Duck and 2 season’s first Greater Scaup. On 23 Oct., the Nanhui microforests yielded Eurasian Woodcock, Ashy Minivet, Siberian Thrush, Red-throated Thrush, and season’s first Pale Thrush. A male Siberian Rubythroat popped out of the undergrowth and a Northern Boobook dozed before a crowd of photographers. At the line of trees (30.859995, 121.910061) near South Lock, 6 km south of the Magic Parking Lot (30.882688, 121.972489), we had season’s first Tristram’s Bunting. Dishui Lake (30.908702, 121.945124) is attracting ducks again, the most notable Sunday being season’s first Tufted Duck and Common Pochard.
The sod farm, which we visited Sunday morning, and which lies just off the S32 freeway, was worth the small investment of time required to get there. The grassy area gave us an unusually large (80) group of Red-throated Pipit. In Nanhui, we have been experiencing this species only in fly-by mode, but at the farm dozens of them were feeding on the ground. Michael and I studied the pipits carefully and concluded the group was pure Red-throated; we saw not a single Buff-bellied Pipit.
Ducks are once again gracing the canals and ponds of Nanhui. The most numerous were, as expected, Eastern Spot-billed Duck (285 over the two days) and Eurasian Teal (270 on 23 Oct.). Less numerous was Eurasian Wigeon, and there were sprinklings of Gadwall, Mallard, Northern Shoveler, Northern Pintail, and Garganey.
— Uniquely among the Shanghai region’s passage-migrant flycatchers, most of which appear in roughly equal numbers on both the spring and autumn migrations, Narcissus Flycatcher appears almost exclusively on the spring migration. We were therefore pleasantly surprised Sunday to see the three males and three females. Did Typhoon Haima send them our way? What are the migration patterns of this beautiful flycatcher?
— The importance of the Nanhui wetlands—as well as the dangers they face—can hardly be overstated. On 20 Oct. at the skua site, Hé Xīn told me that the defunct wetland in which we were standing would already have been utterly transformed by now had it not been for the intervention of Chinese birders, who secured a one-year delay. Within a radius of a few hundred meters of the skua site stood 24 endangered Black-faced Spoonbill and an endangered Nordmann’s Greenshank. The dependence of Black-faced Spoonbill on the defunct wetland reserve is obvious and could be demonstrated by a group of high-schoolers doing a science project. Shanghai lies at the mouth of one of Earth’s greatest waterways (the Yangtze River) and is a major point on Earth’s greatest migratory flyway—yet this wealthy city, a world financial center with a rich natural heritage, entirely lacks an easily accessible wetland reserve on its mainland. The one, weak attempt—the defunct Nanhui reserve, with its crumbling buildings, torn-up boardwalk, and rotting signs—stands near the gallows, in the nick of time being given a stay of execution. And yet, even now, the defunct reserve, mismanaged, unloved, and undervalued, even now the place still attracts Class A birds! When, oh when, will the Shanghai government and Shanghai people learn to value at their true worth their spoonbills, greenshanks, and vagrant skuas? When, I ask, will they see as an asset to be cherished, and not a burden to be cast away, the thousands of birds that migrate through Earth’s greatest city? When will the Shanghai people apply their renowned cleverness and skill to protecting, rather than dredging up the home of, the symbol of their city, Reed Parrotbill? When will Shanghai take a cue from Hong Kong and build its own Mai Po? When will it follow the example of Singapore and create its own Sungei Buloh?
Note: Nearly every major field guide covers skuas, a cosmopolitan family. This is a partial list showing the main works I consulted as I researched Stercorariidae.

Editor’s note: Our featured image above, which shows a Spoon-billed Sandpiper and question mark, sets the theme for this post, in which we raise this question: In the face of manic coastal development in China, what will become of Spoon-billed Sandpiper, among the most highly endangered shorebirds in the world? The unique “spoon,” or spatulate bill—will future generations look on in wonder at it?
In Yangkou, the famous birding location in Rudong County, Jiangsu, my partners and I on Mon. 3 Oct. 2016 found a roost of 10,300 waders. We encountered this stunning spectacle on a reclaimed parcel of mudflat that will soon be transformed into a kite-flying ground for the tourists. Have you ever wondered why species such as Spoon-billed Sandpiper and Nordmann’s Greenshank are on the brink? This picture will help answer your question:
If other nearby areas are suitable, then why would so many shorebirds choose to roost literally in the shadow of the clanging backhoes and roaring dump trucks?
Simple. Because there are no better areas.
Spoon-billed Sandpiper, Nordmann’s Greenshank, Far Eastern Curlew, Great Knot, and dozens of other shorebird species are being squeezed by coastal development, precisely of the sort shown in the photo above.
Surveying the strange scene, my partner Jan-Erik Nilsén said, “I feel the way I felt with the Spoon-billed Sandpiper yesterday—that I’m saying goodbye.”
Jan-Erik was referring to the events of Sun. 2 Oct. 2016 on the coast of Dongtai County, 35 km (22 miles) north of Yangkou. There we found 13 Spoon-billed Sandpiper foraging at the base of the sea wall at low tide. We watched as the sandpipers casually made their way to within 20 meters of our front-row seat on the wall.
Tempering our delight was this dark thought: Every last square inch of the area on which those endangered birds were foraging is slated for yet more reclamation. The disaster unfolding now at Yangkou may well strike Dongtai.
For now, Dongtai is still magical, with unbroken vistas from sea wall to horizon. For this reason, Dongtai has replaced Yangkou as the world’s best place to observe Spoon-billed Sandpiper and Nordmann’s Greenshank.
But if Dongtai goes the way of Rudong County, then yet another step will have been taken in locking up the Chinese coast—and throwing away the key.
Our long look at Spoon-billed Sandpiper highlighted a three-day birding trip over Chinese National Day. My wife Elaine Du and I birded with Shanghai-based British birder Michael Grunwell and Jan-Erik, a Swede working in Beijing. The big roost at Yangkou plus a day and a half at Dongtai helped take our three-day coastal-birding total to 125 species. We had 29 Nordmann’s Greenshank and 35 Black-faced Spoonbill on Sunday at Dongtai, 6 Chinese Egret at the big roost at Yangkou and at Dongtai, and Little Curlew at the big roost.
Also notable were 230 Eurasian Oystercatcher at Dongtai; 19 Whimbrel at Dongtai as well as at our third site, Chongming Island in Shanghai; just 34 endangered Far Eastern Curlew at Dongtai; 573 Eurasian Curlew at Dongtai, including a big count of 570 on Sunday; plus 71 Great Knot, 144 Red Knot, an unusual view of Temminck’s Stint on the mudflats, Grey-tailed Tattler, and Lesser Black-backed Gull.
Finally, passerines: at Dongtai, Chinese Grey Shrike, Hair-crested Drongo, Red-rumped Swallow and Asian House Martin as well as a lone Yellow-bellied Tit migrating south along the sea wall. Also season’s first Pallas’s Leaf Warbler, Mugimaki Flycatcher, Taiga Flycatcher, White-throated Rock Thrush, Red-throated Pipit, and Little Bunting. We found Siberian Thrush and many other passerines at a wooded area around a sluice gate (32.722313, 120.942883). Still missing from our autumn 2016 Shanghai-area list: Bull-headed Shrike, Red-flanked Bluetail, Daurian Redstart, and all Turdus thrushes except Chinese Blackbird.
The big wader roost at Yangkou was made up mainly of Kentish Plover (6500) and Dunlin (2800). Inland we found Chinese Bamboo Partridge (a new Yangkou record for me) and Black-winged Kite.
At Yangkou, in our van we followed 3 Lesser Cuckoo along a line of trees paralleling the road. The sustained view plus photos clearly indicated Cuculus cuckoos of a thrush’s size, not a falcon’s size. Credit goes to Michael for quickly noting the small size of the cuckoo and encouraging me to take the leap beyond “Cuculus sp.” Jan-Erik supported Michael, and after viewing the dozens of photos we took, it was obvious they were right.
— The “Temple Forest” (32.560253, 121.039793), the famous migrant trap at Haiyin Temple in Yangkou, has lost much of its value to birders. The Temple Forest was unparalleled as a migrant trap, routinely offering up a stunning array of species drawn to the cover of the leaves. A mini-zoo set up earlier this year in the unwooded areas has since expanded into the wood itself, with cages, mini-cottages, and fences throughout. As the trees are still standing, flycatchers and leaf warblers may continue to use the area.
— One bright note is the small wood next to the lighthouse at Haiyin Temple (32.561881, 121.040619). Fishermen who had been squatting there have moved out, and the area has been cleaned up. A sidewalk now runs past the wood. It is probably too small an area to be developed, and as it has the very best location right at the tip of the headland, it will continue to attract migrating birds.
The autumn migration season here in Shanghai has kicked off in style. Leading the parade of migrants is Fairy Pitta, seen in Microforest 2 at Cape Nanhui on Sat. 3 Sept. 2016 and still there as of Sunday afternoon. Another notable sighting on Saturday was Common Ringed Plover at the sod farm south of Pudong International Airport.
Partnering yet again with Shanghai-based British birder Michael Grunwell, Elaine Du and I were out Sat. 27 Aug. and again the following Saturday, 3 Sept. On both days we found Asian Dowitcher and endangered Great Knot. On 3 Sept. a group of 135 Great Knot and 3 Asian Dowitcher were part of a wader roost of ca. 400 individuals in the canal between microforests 1 and 2. The roost also contained a single endangered Nordmann’s Greenshank, 30 Red Knot, and 3 Curlew Sandpiper. On the mudflats nearby, we had a flyby of 3 endangered Far Eastern Curlew. On 27 Aug. a smaller roost at the same location had some of the species noted above as well as Grey-tailed Tattler. 27 Aug. also yielded a single Red-necked Phalarope.
Other highlights from 3 Sept.:
26 Pin-tailed/Swinhoe’s Snipe at sod farm near Pudong Airport
ca. 200 near-threatened Black-tailed Godwit in that wader roost at Nanhui
516 Eastern Yellow Wagtail, most of this impressive number from Pudong Airport sod farm and the Nanhui sod farm on Ganlan Road (30.890865, 121.902011)
— On Sat. 27 Aug. we added to our trio special guest Mikkel Thorup, a mathematician from Denmark. This was not Mikkel’s first birding trip in China, but he is still fresh enough that he was picking off lifers left and right. Later, we were joined by the international high-school birding team of Komatsu Yasuhiko (Japan), Larry Chen (Canada), and Chi Shu (Shanghai).
— The decline of Lesser Yangshan as a birding spot is accelerating. Garbage Dump Coastal Plain has been lost to birding, with earth-moving machines all around and new buildings going up. Garbage Dump Gully is intact, but the increased activity on the coastal plain means that security, already tight now, may be even tighter in the future, and it may soon prove impossible to reach the gully. A migrant trap par excellence, Garbage Dump Gully is crucial to Shanghai birders. Over the years the gully has given birders Japanese Robin, Verditer Flycatcher, Varied Tit, White-bellied Green Pigeon, and scores of other good records. Garbage Dump Gully must be preserved; access to it must be sustained.
— On 27 Aug. we found a banded Black-tailed Godwit. As is my habit, I filled out and submitted the Leg Flag Report Form on the Web site of the Australasian Wader Studies Group. Our godwit, it turns out, received its bands on 19 June 2016 on the Kamchatka Peninsula in Russia (at 57.08, 156.64), 4000 km from Shanghai. UPDATE: On 9 Sept. 2016 a godwit with the E7 band was found by Chinese photographer kaca at virtually the same location as the 27 Aug. sighting.
— The task of ID-ing the Nordmann’s was clear-cut and was helped along by a Common Greenshank that appeared next to the Nordmann’s. The head of the Nordmann’s was proportionally larger than that of the Common, and it had a higher knee with shorter legs—an obviously stockier bird, a rugby player compared to a ballerina. The Nordmann’s stretched out its wing, revealing clean white plumage underneath. Common has a greyer underwing.

The past 10 days have seen a parade of migrants passing through Shanghai. Grey-crowned Warbler and Blue Whistling Thrush shocked birders at Cape Nanhui. The birding site in southeast Pudong also yielded Pheasant-tailed Jacana, Pacific Golden Plover, Red Knot, Grey-tailed Tattler, Amur Paradise Flycatcher, singing Arctic Warbler, calling Two-barred Warbler, Radde’s Warbler, White-throated Rock Thrush, and still more Pechora Pipit. Tiger Shrike and Black Bulbul have been noted at Nanhui and on Lesser Yangshan, with the latter location yielding Peregrine Falcon and Rufous-tailed Robin singing from deep cover. Other interesting records were Red Turtle Dove, Black-winged Cuckooshrike, Hair-crested Drongo, Ashy Drongo, day counts as high as 21 of Black Drongo, a trio of Siberians (Siberian Thrush, Siberian Blue Robin, Siberian Rubythroat), plus Chestnut Bunting and endangered Yellow-breasted Bunting. Zhongshan Park yielded our season’s first singing Black-naped Oriole. My friend Kai Pflug was one of a group of birders who found Fujian Niltava at Nanhui, a first for Shanghai.
At this time of year, considering the richness of the Shanghai coast and the lack of birder coverage over the years, I go out not hoping, but expecting to get interesting records. Recently, I have rarely been disappointed.
GREY-CROWNED WARBLER, RARE IN SHANGHAI
Though I missed Kai’s niltava, the German birder brought me good luck in another way. On a spectacular Tues. morning 17 May at Nanhui, exploring the lush microforests, he and I found Grey-crowned Warbler Seicercus tephrocephalus.
The bird was singing, an amazing incongruity, the bright, sharp south-Chinese Seicercus sound here in a tiny wood on the muddy Chinese coast. The golden warbler alighted on a branch for several seconds. I got photos and a sound recording. Grey-crowned Warbler is rarely seen this far east and is not covered in Mark Brazil’s Birds of East Asia. However the very good Handbook of the Birds of the World Vol. 11, which I can’t recommend enough to lovers of leaf warblers and golden spectacled warblers, has the info we need.
A monotypic species, S. tephrocephalus is said by HBW 11 to breed closest to us in Hubei. It is very simliar in plumage and song to Martens’s Warbler S. omeiensis but unlike Martens’s has eye-ring broken at rear. S. tephrocephalus is common to abundant in its normal range of south China and Southeast Asia, but it has rarely if ever been recorded in Shanghai. The lack of records is owing not only to its scarcity but also to its difficulty in identification, particularly for birders unfamiliar with HBW 11.
Much of the wealth of info on Seicercus warblers in HBW 11 is the fruit of the research of Swedish ornithologist Per Alström, who wrote nearly all the Seicercus entries. Guangdong-based French birder Jonathan Martinez has also researched S. tephrocephalus and helped me with the ID of the Grey-crowned Warbler. Both are members of the Shanghai Birding WeChat group and are readers of shanghaibirding.com. Thanks to both of you for your contributions.
Here are the sound-recordings I made of Grey-crowned Warbler. The recordings and photos are of the same individual.
After viewing the photos and listening to the recordings, Per wrote the following to the Shanghai Birding chat group:
“Hi Craig. … I agree with your id of Grey-crowned Warbler, mainly based on the song recording (songs and calls are by far the best ways to id Seicercus warblers). The photos look a bit off (e.g., eye-ring broken in front, which isn’t normally the case in any Seicercus, seemingly poorly marked lateral crown-stripes, no clear grey on crown [though that could be a photo effect], and dark-tipped lower mandible [only in Grey-cheeked W]). Simple id tips, paintings and a few photos can be found on my research web page. In a PDF on leaf warblers from a talk for Beijing Birdwatching Society, there are also sound recordings of … Seicercus warblers on the same page.” (That very useful PDF is now available for download through shanghaibirding.com [13 MB]: Phylloscopidae-Beijing-Birdwatching-Society-nov-2012 English)
To sum up:
My research indicates, and Per Alström concurs: Grey-crowned Warbler (Seicercus tephrocephalus)
Grey-crowned has eye-ring broken at rear; my photos show eye-ring broken at rear. The songs I recorded most closely match the song of S. tephrocephalus.
Next-closest possibility: Martens’s Warbler (S. omeiensis)
Very similar to Grey-crowned Warbler but doesn’t have eye-ring broken at rear.
Also: Alström’s Warbler (S. soror); my recording has trills; distinctive song of Alström’s lacks trills. Bianchi’s Warbler (S. valentini) does not trill. White-spectacled Warbler (S. affinis intermedius) has eye-ring broken above eye, not behind.
BLUE WHISTLING THRUSH, ANOTHER RARITY IN SHANGHAI
A coastal record of Blue Whistling Thrush is rare; the species had not been recorded in Shanghai since 1987. The places closest to Shanghai where I’ve seen the species are Tianmu Mountains in Zhejiang and in Nanjing Zhongshan Botanical Garden. When on Sun. 15 May we first saw the glossy blue-black bird, my partners Jan-Erik Nilsén and Elaine Du and I were flummoxed. We lingered around microforests 3-8 at Nanhui, waiting to get another look. We finally got a second look and realized it was whistler.
Birders tend to think of Blue Whistling Thrush as the ultimate resident, a fixture along fast-flowing mountain streams. The bird is however at least partly migratory, as our record and observations of other birders prove. In a text message to the Shanghai Birding WeChat group, Jonathan Martinez wrote: “BWT are migrants; I used to have them annually in northern Hunan at a site not suitable for breeding.”
CUCKOOS ARE CALLING IN SHANGHAI!
One of the many reasons I love spring is that during this time cuckoos call and are easier to identify. On Tues. 17 May at Nanhui Kai Pflug and I had two calling cuckoos: Common and Indian. I got photos of both. Can you see differences in the appearance of Common and Indian? One is eye color. See four-panel photo for comparison. The other is the thickness of the barring on the underparts. Indian also is smaller than Common, but the size difference is harder to see.
Here is one of the best-known bird calls in the world, that of Common Cuckoo, recorded by me at Nanhui on 17 May (00:31; 2 MB):
— More Nanhui notes from Tues. 17 May: 0 ducks, 0 raptors, and Dishui Lake contained a grand total of 3 birds, all Great Crested Grebe. Also, on a weekday, even though weather superb, tourists were few; Kai Pflug and I enjoyed blessed peace and quiet. It was as quiet as a rainy Saturday or Sunday. We were lovin’ that!
— On Tues. 17 May Kai and I found bird netting at “Dowitcher Pond” (30.877779, 121.955465) in Nanhui. Area is fenced in and netting was tied to posts in deep water, so removing it will be a challenge.
— Here is a recording I made of Arctic Warbler at Nanhui.
— Here is the sound of Rufous-tailed Robin singing on Lesser Yangshan. The robins were singing unseen on the thickly vegetated hillside above the tunnel entrance at Xiǎoyánglíng Cove (30.642243, 122.066940).

— Thanks to our birding partners Michael Grunwell, Jan-Erik Nilsén, and Kai Pflug.
Featured image: Here’s a handy rule for bird photographers: When you have light conditions as good as those we had Tues. morning 17 May 2016, then shoot anything, even a sparrow. It’ll look good. Luckily I had this more interesting Common CuckooCuculus canorus. I was at Cape Nanhui in Shanghai. Nikon D3S, 600 mm, F6.3, 1/5000, ISO 6400.
