The Cuckoos of Shanghai

Editor’s note: The image above shows three cuckoos of the Shanghai region. Clockwise from L: Rufous Hawk-Cuckoo, Chestnut-winged Cuckoo, and Large Hawk-Cuckoo. Join us as we study the rich array of cuckoos that passes through Earth’s greatest city.

It is spring, and one of the most thrilling moments of the bird migration in Shanghai is upon us–the passage of the Cuculinae, the Old World brood-parasitic cuckoos. Nowhere in the world is the diversity of this group greater than in eastern Eurasia, and here in Shanghai we get an enviable selection. Let us examine our Shanghai-area parasitic cuckoos and learn how to tell them apart.

We can divide the Shanghai-area brood-parasitic cuckoos into two categories: the mainly grey, slender-bodied Cuculus cuckoos and the non-Cuculus cuckoos. We will look at the non-Cuculus cuckoos first.

MASTER MIMICS: THE HAWK-CUCKOOS

The non-Cuculus parasitic cuckoo that one is most likely to see in Shanghai is Large Hawk-Cuckoo Hierococcyx sparverioides. In the microforests at Cape Nanhui and once, to my surprise, in inner-city Zhongshan Park, I have heard the scream of “Brain fever!” The species breeds in nearby Jiangsu and Zhejiang.

The hawk-cuckoos mimic sparrowhawks, an amazing feat of evolution. The resemblance serves, scientists say, not to increase stealth but to decrease it. Passerines, mistaking the intruder for a sparrowhawk, mob it, thereby giving away the location of their nest. After the tumult dies down, the hawk-cuckoo quietly swoops in and lays her egg.

Hawk-cuckoos have bills quite unlike those of the sparrowhawks that they mimic. L: Japanese Sparrowhawk. R: Large Hawk-Cuckoo. (Craig Brelsford, Kai Pflug)

When it comes to the business of eating, however, the masquerade ends. The hooked bill of a sparrowhawk is a butcher’s tool, made for stripping the flesh of vertebrates from bone. The bill of a hawk-cuckoo is blunt, the utensil of a caterpillar-eater. Need a quick differentiator between “sprock” and hawk-cuckoo? Look to the bill.

Another separation we Shanghai birders need to make is that between Large Hawk-Cuckoo and Rufous Hawk-Cuckoo Hierococcyx hyperythrus. If seen clearly, adult Large Hawk-Cuckoo and Rufous Hawk-Cuckoo are readily separable. Rufous Hawk-Cuckoo shows a belly washed rufous with faint streaks. Large Hawk-Cuckoo is heavily barred and streaked and has the rufous coloring confined to the upper breast.

L: Rufous Hawk-Cuckoo (Craig Brelsford). R: Large Hawk-Cuckoo (Kai Pflug)
Adult Rufous Hawk-Cuckoo (L) shows (1) white neck-sides and nape patch, (2) white scapular crescents, and (3) a rufous border to the black subterminal band on the tail. Large Hawk-Cuckoo (R) shows none of these. L: Original Magic Forest (32.567487, 120.996980), Yangkou (Rudong), Jiangsu, 15 Sept. 2012 (Craig Brelsford). R: Cape Nanhui, Shanghai, April 2017 (Kai Pflug).

Adult Rufous Hawk-Cuckoo shows a white spot on the nape, white neck-sides, and white scapular crescents. These features may also be visible in sub-adult Rufous Hawk-Cuckoo. Large Hawk-Cuckoo shows none of these in any plumage.

Rufous Hawk-Cuckoo Hierococcyx hyperythrus. The lack of rufous wash on the breast and belly suggests that this is a juvenile. The grey streaking of the adult plumage has appeared. Also visible are the white nape patch and scapular crescents as well as the rufous bands on the tail. Original Magic Forest (32.567487, 120.996980), Yangkou (Rudong), Jiangsu, 6 Oct. 2010. (Craig Brelsford)

Size differences may be appreciable. An average Large Hawk-Cuckoo is 15 percent larger than Rufous Hawk-Cuckoo. The tails differ, with the black subterminal band of Rufous Hawk-Cuckoo being bordered by a rufous line above and by the rufous tail-tip below. These rufous areas may be visible in immature cuckoos.

ASIAN KOEL AND CHESTNUT-WINGED CUCKOO

L: Asian Koel, female, 2 June 2016, Nanhui, Shanghai (Kai Pflug). R: Asian Koel, male, 17 May 2015, Dongtai, Jiangsu (Craig Brelsford).

Eudynamys scolopaceus chinensis is the northernmost-breeding race among the koels, a small, mainly tropical group.

The other non-Cuculus parasitic cuckoos of the Shanghai region are Asian Koel Eudynamys scolopaceus and Chestnut-winged Cuckoo Clamator coromandus. Neither offers great ID challenges.

In China, Asian Koel ssp. chinensis breeds mainly south of the Yangtze River. With its familiar “koh-EL” song, Asian Koel is as easy to hear as it is hard to see in the dense forests where it is almost invariably found. It shows strong sexual dimorphism, with the male entirely glossy bluish-black and the female brown with whitish streaks, bars, and spots.

The parasitic cuckoos are secretive and most conspicuous by sound. A poor, fleeting glimpse is all that one is likely to get. That was the case in the Tianmu Mountains with this Chestnut-winged Cuckoo. (Craig Brelsford)

In the Tianmu Mountains (30.344148, 119.440201) on 10 May 2015, this poor, fleeting glimpse was all I could manage of this Chestnut-winged Cuckoo. Its presence was more than made known, however, by its piercing whistle and harsh cries. (Craig Brelsford)

I have yet to see Chestnut-winged Cuckoo in Shanghai. It has been noted at Tongshan Forest Park (32.348637, 119.106915) in Yangzhou, Jiangsu, and I have noted it at Laoshan (32.071265, 118.560699) in Nanjing as well as in Zhejiang in the Tianmu Mountains (30.344148, 119.440201). With its glossy-black erectile crest, rufous wings, and long, black tail, the species is unmistakable–if you can manage to see it.

SHANGHAI-AREA CUCULUS CUCKOOS

Five Cuculus cuckoos have been claimed for Shanghai: Lesser Cuckoo Cuculus poliocephalus, Indian Cuckoo C. micropterus, Himalayan Cuckoo C. saturatus, Oriental Cuckoo C. optatus, and Common Cuckoo C. canorus.

The latter breeds in the area, parasitizing the nests of Oriental Reed Warbler in the reed beds at Cape Nanhui. Its famous song, perhaps the best-known bird sound in the world, is hard to miss at Nanhui in May.

Lesser Cuckoo and Indian Cuckoo breed in the region and are recorded on passage in Shanghai. Himalayan Cuckoo and Oriental Cuckoo may pass through Shanghai, but inasmuch as in size, plumage, and bare parts they are nearly identical to each other and very close to Common Cuckoo, and because they rarely (if ever) sing in our region, it is impossible to know how common they are.

Common Cuckoo (L) is the size of a sparrowhawk and is appreciably larger than the thrush-sized Lesser Cuckoo (R). Himalayan Cuckoo is on average smaller than Common, but the size difference is more difficult to appreciate. L: Nanhui. M: Foping, Shaanxi. R: Old Erlang Road, Sichuan. (Craig Brelsford)

Hear the song of any of these Cuculus, and you will have your ID; even the similar songs of Himalayan and Oriental are readily separable. If your cuckoo is silent, however, then you will need a closer look. Lesser Cuckoo and Indian Cuckoo have a brown iris, Common a bright-yellow iris. Lesser Cuckoo is the size of a thrush; Indian Cuckoo is a third larger; Common Cuckoo is larger still, approaching the size of a female Eurasian Sparrowhawk.

Juvenile <em>Cuculus</em> cuckoos are very difficult to ID to species. This is especially true in Shanghai, where almost all <em>Cuculus</em> cuckoos are passage migrants. If however you are on the breeding grounds and know a little about the host species, then you may be able to attempt an ID. In this photo, taken 22 July 2010 at Balangshan (<a href="https://www.google.com/maps/place/30%C2%B057'39.5%22N+102%C2%B052'42.2%22E/@30.960977,102.7383223,11z/data=!4m5!3m4!1s0x0:0x0!8m2!3d30.960977!4d102.878398" target="_blank">30.960977, 102.878398</a>) in <a href="https://www.google.com/maps/place/Sichuan,+China/@30.1028528,93.9726458,5z/data=!4m5!3m4!1s0x36e4e73368bdcdb3:0xde8f7ccf8f99feb9!8m2!3d30.651226!4d104.075881" target="_blank">Sichuan</a>, the juvenile cuckoo that the Rosy Pipit is feeding is most likely Common Cuckoo. The hugeness of the cuckoo is a clue, but the strongest indicator may be the foster parent. Common Cuckoo is known to parasitize the nests of pipits, while Himalayan Cuckoo and Lesser Cuckoo favor small warblers and Indian Cuckoo favors drongos and shrikes. (Craig Brelsford)

In autumn, juveniles pass through Shanghai. They are silent and nearly impossible to identify to species. If one gets a close look at juvenile Lesser Cuckoo, however, one may appreciate its thrush-like size. If you happen to be on the breeding grounds, then you can attempt an ID according to the species of the foster parent.

NON-CUCULINAE CUCKOOS

Lesser Coucal Centropus bengalensis is the good guy of the Shanghai cuckoo world. Unlike all the other cuckoos recorded in Shanghai, but like most of the cuckoos in the world, the coucals are not brood parasites. Lesser Coucal, resident in Shanghai, builds a dome nest on the ground.

Lesser Coucal may be the only non-Cuculinae cuckoo in Shanghai, but it shares at least one trait with the brood parasites: It is very unobtrusive. Look for Lesser Coucal in areas of thick vegetation near water, such as the strips of reed bed along the canals at Cape Nanhui. If you find one, count yourself lucky.

Greater Coucal Centropus sinensis occurs south of our region. It is nearly half again as large as Lesser Coucal and has a cleaner and glossier mantle, a thicker bill, and a redder iris.

EASTERN CROWNED WARBLER SINGING IN SHANGHAI

Eastern Crowned Warbler, 30 Sept. 2014, Yangkou (Rudong), Jiangsu. One of the Big 5 Leaf Warblers of ShanghaiPhylloscopus coronatus is a common autumn and spring passage migrant in Shanghai. It is usually silent in Shanghai, but on 15 April 2017, I heard one sing in Century Park. Migrating birds often sing snatches of song far from their breeding grounds. On 7 April 2016, also at Century Park, I heard White’s Thrush sing. (Craig Brelsford)

In Shanghai, the best birding occurs on the coast, 80 km from the city center. Getting there can be a chore. Birding Pudong’s Century Park, by contrast, only requires a ride on Metro Line 2. Your day list from Century will only be about a third as long as a list from Cape Nanhui, but good birding can occur there, and at little cost.

On Sat. 15 April 2017, my partners Larry Chen, Komatsu Yasuhiko (“Hiko”), Hiko’s biology teacher Zeng Qiongyu, and I had a bout of good birding at Century Park.

I had never heard Eastern Crowned Warbler sing in Shanghai. I am however very familiar with the song, because in my wife Elaine Du’s hometown of Boli, Heilongjiang, the song of Eastern Crowned Warbler is one of the most common sounds in the remnant Manchurian forest. Elaine and I have birded Boli on three occasions, most recently in May-June 2016.

We were in the heavily wooded area near Gate 7 when I heard the wheezy song. It sounded just like this recording I made in Heilongjiang:

It was just a snatch of song, and it occurred but once. I knew immediately that it was Eastern Crowned Warbler. The song was coming from the surprisingly high canopy of the wood.

All four of us strained to find the bird. The sun shone brightly through the canopy and into our eyes. Finally, Hiko saw movement. Through the glare we focused in and got a clear view of Eastern Crowned.

It was a shot of birding as good and satisfying as I get anywhere. And it just goes to show–good birding can occur anywhere, even in a busy city park.

Rites of Spring

For birders in Earth’s greatest city, finding Oriental Plover is one of the rites of spring. Last Sun. 26 March 2017 on Shanghai’s Hengsha Island, our three-man birding team tracked down 25 of these passage migrants. The encounter was the latest in a series of interesting experiences I have had with the East Asian specialty.

Along with Shanghai birders Michael Grunwell and Komatsu Yasuhiko, I drove on Saturday night 25 March to Changxing Island, crossing to Hengsha on the ferry. We set up for the night at my accustomed bed and breakfast, Héngshā Bànrìxián Mínsù (横沙半日闲民宿, +86 150-2164-5467, no English).

For Shanghai birders, seizing the brief opportunity to view this East Asian specialty is an annual rite of spring. (Craig Brelsford)

At 05:40 the next morning we zipped through the gate (31.297333, 121.859434) to the vast reclaimed area of Hengsha Island. Formerly intertidal shoals at the mouth of the Yangtze River, the area, now walled in, offers some of the best birding in Shanghai.

Michael and Hiko had no experience with Oriental Plover. I have seen the species various times. One of the highlights of my early birding career occurred on 29 March 2010. On a cool, early-spring afternoon, I lay on my belly in the presence of 30 Oriental Plover at the old sod farm (31.205847, 121.777368) at Sanjiagang in Pudong. What an unforgettable experience that was.

The sod farm has long since been destroyed, but memories of those times, as well as my observations of the species on its breeding grounds near Hulun Lake in Inner Mongolia, still live in me, and they told me where to look for the bird. One needs to find habitat reminiscent of the dry, stony steppe on which it breeds.

On Hengsha, such habitat is abundant, and we scoured all the likely spots, among them the place where my wife Elaine Du and I found 3 Oriental Plover last April 9.

We were driving along the coastal road that skirts the southern edge of the reclaimed area. The morning was hazy, with air pollution giving me the sniffles, but even with the reduced visibility one could appreciate the power of the Yangtze looming behind.

Here, the longest river in Asia releases into the East China Sea the water collected along its course of 6,300 km (3,915 mi.). On clear days, one can see the famous skyline of Pudong, 38 km (24 mi.) away. At Hengsha Island, one stands on the eastern edge of Eurasia at the mouth of China’s greatest river in the shadow of Earth’s greatest city.

As we drove, the reed beds and marshy areas began to recede, and there opened up before us drier, grassier habitat, perfect for Oriental Plover. Stopping the car, I intoned, in a voice recalling Brigham Young, “This is the place.” (The coordinates are 31.301475, 121.917442.)

We broke out a forest of tripods and set upon them our spotting scopes. Michael, the seasoned veteran, saw the plovers first. Continuing our Wild West theme, Michael shouted, “Eureka!” His head was motionless, glued to the scope, but his arms were waving, and he was dancing a jig. The 49er had just struck gold.

Michael and Hiko moved in for a closer look. I stayed above, scanning the scene through my Swarovski ATX-95. Males and females were in partial breeding plumage. They were running fast across the turf, picking off invertebrates. Twice they flew, and I appreciated their powerful, erratic flight and long wings.

We found 16 Oriental Plover there. We found another 9 on the north shore of the reclaimed area, on the mudflats.

NOTES ON ORIENTAL PLOVER

Oriental Plover breeds mainly in Mongolia. The breeding range extends into China in Hulunbeier, the northernmost portion of Inner Mongolia. In Shanghai, Charadrius veredus is an uncommon springtime passage migrant.
Oriental Plover breeds mainly in Mongolia. The range extends into China in Hulunbeier, the northernmost prefecture of Inner Mongolia. In Shanghai and at various places along the Chinese coast, Charadrius veredus is an uncommon springtime passage migrant. Autumn records are scanty, and the migration route of Oriental Plover south through China is not entirely clear. Map by Wikipedia/Craig Brelsford.

Oriental Plover Charadrius veredus is listed as a species of Least Concern by the IUCN. A survey in 2010 came up with an estimated world population of 160,000, an encouraging number. The species is helped by the sparse human population both in the area where it breeds (mainly Mongolia) and where it winters (mainly Australia).

The species may be helped as well by its migration patterns. There is evidence that migrating Oriental Plover overfly much of Southeast Asia and possibly even China, areas where the hand of man is much heavier than in Mongolia and Australia.

In the entry for Oriental Plover in Handbook of the Birds of the World, T. Piersma mentions a “scarcity of records between China and the non-breeding grounds,” suggesting that migrating Oriental Plover make a “non-stop flight between these two zones.” Robson, in Birds of Southeast Asia, describes Oriental Plover as a “vagrant/rare passage migrant.”

Oriental Plover doze just meters away from the photographer at Sanjiagang, 29 March 2010. It is probable that these plovers had just completed a very long flight, possibly all the way from Australia, before landing here. Craig Brelsford.
Exhausted Oriental Plover doze just meters away from the photographer at Sanjiagang, 29 March 2010. These plovers had probably just completed a very long leg of the journey from Australia to Mongolia. (Craig Brelsford)

Piersma says Oriental Plover is “very abundant” on migration in the Yangtze River Valley. That is doubtful. Oriental Plover are certainly not abundant in Shanghai; indeed, in autumn they are virtually unrecorded here (as well as in much of eastern China). The city may nonetheless serve as a staging area for some portion of the species in spring.

My anecdotal evidence may lend credence to the idea that Oriental Plover fly mind-boggling distances between Australia and Mongolia. During my close encounter with the 30 Oriental Plover at Sanjiagang, the plovers were clearly exhausted. Some fell asleep right in front of me. How many kilometers had they just flown? Hundreds? Thousands?

The pure white head of breeding male Oriental Plover is diagnostic. Sanjiagang, 2 April 2010. Craig Brelsford.
This male Oriental Plover has nearly attained full breeding plumage. Note the diagnostic white head, still showing some of the darker non-breeding feathers. Charadrius veredus is the Ghost Rider of plovers. Sanjiagang, 2 April 2010. (Craig Brelsford)

Oriental Plover is most closely related to, and was once considered conspecific with, Caspian Plover Charadrius asiaticus. Breeding male Oriental Plover is readily distinguishable from Caspian by its purely white head. The thick black breast band on breeding Oriental male is also distinctive.

Non-breeding Greater Sand Plover and Lesser Sand Plover are smaller and more compact and have narrower breast bands than non-breeding Oriental Plover. In flight, Oriental Plover lacks the white wing bar seen on the sand plovers.

Loons Near Pudong Airport

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.

Red-throated Loon Gavia stellata, Sanjiagang Seaside Park (31.217928, 121.768172). Photo by Kai Pflug. On Sun. 19 March 2017, a day after Michael Grunwell and I viewed it, this loon was discovered dead at the water park. It may have been a victim of poisoning through the ingestion of oil that had collected on its feathers.

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.

The feet of loons are placed far back on their body. Their resulting ungainliness on land is obvious even on a resting loon, as here. Laotieshan, Liaoning, 18 Sept. 2013. Photo by Craig Brelsford.
The feet of loons are placed far back on the bulky body, making loons powerful divers and clumsy walkers. Note the dagger-like bill, elongated head, and thick neck, characteristic of all five species in the loon family Gaviidae. I found this Black-throated Loon on 18 Sept. 2013 at Laotieshan, Liaoning (38.730483, 121.134018).

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.

GULLING WITH BIRDERS IN MY POCKET

On Sat. 18 March at Binjiang Park (31.2356935, 121.4973863), with the Pudong skyline looming behind, Michael Grunwell and I scanned the gulls on the Huangpu River.

“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!

By its second winter, Slaty-backed Gull (C) shows a mantle darker than that of all other gulls in our region. Note the contrast in mantle color between Larus schistisagus and the adult Vega Gull L. vegae vegae/mongolicus surrounding it. Photo by Craig Brelsford using iPhone 6 and PhoneSkope adapter attached to my Swarovski ATX-95 spotting scope.
By its second winter, Slaty-backed Gull (C) shows a saddle a darker shade of grey than that of all other gulls in East Asia. Note here the contrast between the slate-grey of Larus schistisagus (top inset) and the lighter grey of the other gulls, all adult Vega Gull L. vegae vegae/mongolicus (bottom inset). UPDATE, 18 APR 2017: In a guest post for shanghaibirding.com about the Widespread Herring-type Gulls of East Asia, Nial Moores says the gull far L is Taimyr Gull L. (heuglini) taimyrensis. Photo by Craig Brelsford using iPhone 6 and PhoneSkope adapter attached to Swarovski ATX-95 spotting scope.

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.

Mongolian Gull Larus vegae mongolicus, Binjiang Park (31.2356935, 121.4973863), 18 March. Tag says ‘AL 62.’ I am looking into the origin of the tag and will update this post when I get more information. This is yet another photo taken with my iPhone 6 + PhoneSkope + Swarovski ATX-95. UPDATE, 22 MAR 2017: Thank you to Nial Moores from Birds Korea for showing me this page about a wing-tagging program for gulls from 2004 in northeastern Mongolia. It is highly possible that the gull above is part of that program. UPDATE, 24 MAR 2017: Gull researcher Andreas Buchheim has written me saying that he himself ringed gull AL 62 on 27 May 2013 at Telmen Lake (48.8, 97.25) in NW Mongolia. Telmen Lake is 2,820 km (1,752 miles) from Shanghai’s Binjiang Park. Buchheim said that when he ringed AL 62, it was already an adult. This means that AL 62 hatched no later than spring 2010 and that the youngest it could be is nearly 7 years old. All large, white-headed gulls breeding in Mongolia, Buchheim said, are mongolicus. Regarding our mongolicus, Nial Moores from Birds Korea said, ‘This individual shows more obvious yellowish tones to the legs than most/any we see here in Korea (where they are invariably pinkish-legged). It is known that some Mongolians on the breeding grounds have yellowish tones to the legs–so perhaps this difference between birds in Shanghai and Korea is to do with hormonal condition pre-migration. It tends to be several degrees colder in Korea than in Shanghai on the same dates, of course.’

Shanghai birders KaneXu (L) and Michael Grunwell share a laugh after discovering that they own the same camera, the Nikon Coolpix P900S. The two were at Sanjiagang Seaside Park on 18 March. When it comes to compact cameras, Nikon and other manufacturers are feeling the heat from smartphones. They know that consumers are turning away from compact cameras because the cameras in smartphones are now so good. They are therefore loading up compact cameras such as the P900S with plenty of power and pricing them competitively. KaneXu and Michael are getting great stills as well as video with their new cameras. Photo by Craig Brelsford.

Your Handy-Dandy Nordmann’s Greenshank ID Primer!

Distinguishing non-breeding Nordmann’s Greenshank from Common Greenshank is a tricky task, but one that reaps rewards. With practice you too can feel the rush that comes when you realize that the greenshank you are viewing is not one of the most common shorebirds in Eurasia, but one of the rarest. On Sat. 17 Sept. 2016 at Nanhui, our team experienced that thrill, picking out a Nordmann’s in a roost holding a few hundred shorebirds.

We noted the following:

— Tibiae of Nordmann’s Greenshank are noticeably shorter than those of Common Greenshank.

Nordmann's Greenshank (L) has an appreciably higher 'knee' than the longer- and thinner-legged Common Greenshank (R). Both photos taken by Craig Brelsford in Yangkou, Rudong, Jiangsu in October 2014 (Nordmann's) and May 2011 (Common).
Nordmann’s Greenshank (L) has an appreciably higher ‘knee’ than the longer- and thinner-legged Common Greenshank (R). Both photos taken by Craig Brelsford at Yangkou. Photo of Nordmann’s taken October 2014; photo of Common Greenshank May 2010.

The picture above makes it clear. The biggest reason Nordmann’s is known as the stockier bird, the rugby player compared to the ballerina that is Common Greenshank, is tibia and leg length.

— Nordmann’s has a thicker neck that it often holds closer to its body and has a pronounced ventral angle (protruding belly), giving Nordmann’s a more hunched appearance than Common.

The larger head and thicker neck of Nordmann's (top) give it a more hunched appearance than the more graceful Common (bottom).

As with many of the characters of these species, the hunched stance of Nordmann’s is not always obvious, especially when the bird is active. Likewise, even a Common sometimes can appear stout. But as one’s observation time grows, the classic features of both species will emerge.

Nordmann’s has a thicker, more obviously bi-colored bill than Common.

As is the case with the legs, the bill of Nordmann's (top) is thicker than the bill of Common (bottom). The more obviously bi-colored bill of Nordmann's is yellow at the base.
As is the case with the legs, the bill of Nordmann’s (top) is thicker than the bill of Common (bottom). The more obviously bi-colored bill of Nordmann’s is yellow at the base. Photo info same as preceding.

Because the Nordmann’s at our Nanhui roost did not fly, we missed the following key characteristics:

The toes of Nordmann’s project just beyond the tail-tip; the toes of Common project farther.

With its shorter legs, Nordmann's Greenshank (top) shows just a bit of toe projection. The longer-legged Common Greenshank (bottom) shows more.

This difference can be subtle, and a good camera is sometimes needed to appreciate it. But it is consistent.

Nordmann’s has a cleaner tail and underwing than Common.

The tail and underwing of Nordmann's Greenshank are clean white (panels 1, 2). The tail and underwing of Common Greenshank are streakier (3, 4). All photos in this section taken by Craig Brelsford in <a href="http://www.shanghaibirding.com/sites/yangkou/" target="_blank">Yangkou</a>, Rudong, Jiangsu in May 2011, May 2014, and October 2014.
The tail and underwing of Nordmann’s are clean white (panels 1, 2). The tail and underwing of Common are browner (3, 4). Photo info same as preceding.

Even if your Nordmann’s is roosting, you can sometimes note the white underwing. Wait for the bird to stretch out its wing.

Other differences

The calls of Nordmann’s Greenshank and Common Greenshank are markedly different. The well-known “chew-chew-chew” call of Common is never made by Nordmann’s.

In breeding plumage the species are more readily distinguishable. Nordmann’s Greenshank is also known as Spotted Greenshank for good reason. The heavily spotted underparts of breeding Nordmann’s are diagnostic. Unfortunately for birders in Shanghai, however, Nordmann’s in full breeding plumage is rarely seen.

Nordmann’s Greenshank Tringa guttifer is an endangered species. Only 500 to 1,000 of these birds are thought to remain. Development along the East Asian coast is the main reason for its decline. Nordmann’s breeds in Russia, passes through China, and winters in Southeast Asia. It is present in the Shanghai area for several months each year.

The Nordmann’s took top billing on a day that saw veteran British birder Michael Grunwell, my wife Elaine Du, and me note 71 species at Nanhui, Lesser Yangshan, and the sod farm south of Pudong Airport (31.112586, 121.824742). We were joined at the roost and Nanhui microforests by the crack high-school birding team of Larry Chen, Komatsu Yasuhiko, Chi Shu, and Andy Lee.

Our Non-Nordmann highlights:

White-winged Tern

We noted 2500 at Nanhui, by far the highest number of White-winged Tern that I have seen. They made quite a spectacle, fluttering like snowflakes over the reed beds.

Common Tern

Three at the roost. Michael and I discussed whether Aleutian Tern, similar to Common Tern in winter plumage, passes through Shanghai and has been overlooked. Check for the red legs of Common; if the legs appear black, then keep investigating; you may have an Aleutian.

Ruddy Shelduck

Ruddy Shelduck is uncommon in Shanghai; I have recorded flocks at Chongming but had never seen the species at Nanhui. We saw a single Ruddy in the marshy agricultural land north of Lúcháo (芦潮; 30.851111, 121.848528).

Black-tailed Godwit, Bar-tailed Godwit, Great Knot, Red Knot, Grey-tailed Tattler

The godwits, knots, and tattlers were in the dry roost with the Nordmann’s. Every one of these species is at least near-threatened; Great Knot is endangered.

Black-winged Cuckooshrike

After the excitement with the Nordmann’s at the roost, the seven of us covered the microforests. Our teamwork paid off with a view of Black-winged Cuckooshrike, an uncommon passage migrant in Shanghai.

Japanese Paradise Flycatcher

Japanese Paradise Flycatcher Terpsiphone atrocaudata is the most numerous member of its genus to pass through the Shanghai region. Amur Paradise Flycatcher Terpsiphone incei also passes through, but in smaller numbers.
Japanese Paradise Flycatcher Terpsiphone atrocaudata is the most numerous member of its genus to pass through Shanghai. Amur Paradise Flycatcher T. incei also passes through, but in smaller numbers. I found this individual, a male, in Microforest 2 (30.926138, 121.970795). Like most male paradise flycatchers on passage in Shanghai, it was missing its spectacular elongated tail feathers.

Yet another near-threatened species, Terpsiphone atrocaudata is common on migration in Shanghai. We noted 10 on Saturday. Care must be taken to separate this species from Amur Paradise Flycatcher T. incei, which passes through Shanghai in smaller numbers. Male and female Japanese have a more extensive dark hood, extending almost to the belly, whereas that of Amur extends only to the upper breast. Consult your field guide for more differences.

On Lesser Yangshan we found Oriental Dollarbird. Our final stop was the sod farm south of Pudong International Airport, where we found 4 Pacific Golden Plover and 200 Oriental Pratincole.
