Crested Goshawk Invades Shanghai

Crested Goshawk has sunk its talons into Shanghai. In the past year, records of the species have come from various locations throughout the city, in all four seasons. This past spring, a pair may have bred at Gongqing Forest Park.

It is remarkable that Crested Goshawk, a species of tropical and subtropical Asia, is even as far north as the Yangtze River. Most field guides show Accipiter trivirgatus indicus, the mainland form, occurring no farther north than Hangzhou. However, members of Shanghai Birding, the WeChat companion to this Web site, have reported Crested Goshawk in Nanjing and Nantong (Jiangsu). Other authorities record Crested Goshawk in Anhui, Henan, and even Beijing.

If the forest-loving goshawk has invaded the coastal, little-wooded, highly urbanized world of Shanghai, then it is not surprising that it would be using urban parks. Some of the parks of Shanghai, such as 102-year-old Zhongshan Park, where I found a pair of Crested Goshawk on 8 Sept., have massive trees and resemble old-growth forests.

Like the avifauna of islands, the birds of urban Shanghai’s green islands live in isolation. Except for stray cats and an occasional Siberian Weasel, urban residents Eurasian Tree Sparrow, Light-vented Bulbul, and Chinese Blackbird have few predators and are abundant.

With the imbalance comes an opportunity for raptors that can tolerate the noise and bustle of Earth’s Largest City. For Crested Goshawk, the pluses of urban living are apparently outweighing the minuses. It has come to feed on the rich store of passerines as well as mammals such as Pallas’s Squirrel.

On 16 May 2017 at Pudong’s Century Park, Shanghai Birding member Xueping Popp captured a Crested Goshawk exploiting the imbalance.

Crested Goshawk devouring Chinese Blackbird, Century Park, 17 May 2017. About this incident, photographer Xueping Popp wrote: ‘I went to Century Park early in the morning to look for Black Bittern. Nothing happened, so I decided to walk a little in the park. Suddenly I heard the cries of Chinese Blackbird. I looked up and saw a Crested Goshawk standing in the nest and eating a chick piece by piece. The scene was brutal, but Crested Goshawk was doing what raptors are supposed to do. I observed the whole process silently until the goshawk finished its meal.’ © 2017 by Stephan Popp & Xueping Popp.

Shanghai Birding member Wāng Jìn Róng (汪进荣) was one of the first birders to record Crested Goshawk in Shanghai. Jìn Róng has seen the species at Zhongshan Park and Gongqing Forest Park as well as on the grounds of the Shanghai Zoo. Jìn Róng took the photo at the top of this post as well as the photos immediately below. All were taken at Zhongshan Park–the photo above this past May, the photos below last December.

In December 2016 this Crested Goshawk made a very rare appearance in Zhongshan Park, Shanghai. Photo by Wāng Jìn Róng (汪进荣).

The Crested Goshawk below, photographed by Shanghai Birding member Kai Pflug at Cape Nanhui, may have been in transit. Cape Nanhui has little tree cover beyond its famous microforests (where Kai got this photo), and Crested Goshawk is rarely recorded there.

RESOURCES ON CRESTED GOSHAWK

Most field guides to Shanghai birds show outdated range maps for Accipiter trivirgatus indicus. Among them are Birds of East Asia (Brazil), A Field Guide to the Birds of China (MacKinnon & Phillipps), Handbook of the Birds of the World Vol. 2, and Raptors of the World (Ferguson-Lees & Christie).

The media below offer a clearer picture of the current status in China of Crested Goshawk.

A Rare Look at salangensis Ashy Drongo

Editor’s note: Each spring and autumn, Ashy Drongo Dicrurus leucophaeus migrates through Shanghai. Race leucogenis breeds close to the Shanghai region and is the subspecies most commonly seen in Shanghai. The recent appearance at Nanhui of ssp. salangensis (pictured above) raises the question of exactly how numerous that central Chinese subspecies is on the Shanghai coast.

How dark was that migrating Ashy Drongo you just saw? You may want to pay attention, because the dark-grey central Chinese ssp. salangensis has been spotted at Cape Nanhui, the coastal birding site in Shanghai. In this post, I lay out the identification criteria for salangensis and the paler, more common ssp. leucogenis. My theory is that salangensis appears at some higher rate in Shanghai than has historically been recorded, which until recently has been not at all. An opportunity to fine-tune our understanding awaits us!

SEPARATING THE SUBSPECIES

Ashy Drongo Dicrurus leucophaeus. All photos by Craig Brelsford except 3a (by Kai Pflug ).
Ashy Drongo Dicrurus leucophaeus. 1, 2b: D. l. leucogenis, Laoshan (32.071265, 118.560699), 4 July 2009. Laoshan, a site in Nanjing, Jiangsu 290 km inland from Shanghai, is a breeding area for D. l. leucogenis. 2a, 4: D. l. salangensis, Nanhui, Shanghai, 15 Oct. 2016. 3a: likely D. l. salangensis, Nanhui, September 2016. 3b: D. l. leucogenis, Dongzhai National Nature Reserve, Henan, 1 June 2010. All photos by Craig Brelsford except 3a (by Kai Pflug).

Ashy Drongo Dicrurus leucophaeus comprises 15 races, of which two are known in the Shanghai region: D. l. leucogenis and D. l. salangensis. D. l. leucogenis, the pale eastern race, is the more common migrant. D. l. salangensis is the darker race and is a vagrant to Shanghai.

A classic leucogenis (panels 1, 2b, 3b) is easy to distinguish from salangensis (2a, 4). A typical leucogenis is pale grey and shows a large white oval patch around the eye. D. l. salangensis is much darker, and its facial patch is reduced and less well defined. Both have a red iris.

Ashy Drongo not only has many races but also shows color variation within each race. The photos here were taken 1 June 2010 at Dongzhai, Henan. The drongo in Panel 1 is a classic pale leucogenis, and the drongo in panels 2 and 3 shows a slaty tone to the upperparts and underparts--though it too is most likely leucogenis.
Ashy Drongo not only has many races but also can show considerable color variation within each race. The drongos shown here were photographed within a few hundred meters of each other on 1 June 2010 at Dongzhai. The drongo in Panel 1 is a classic pale leucogenis. The drongo in panels 2 and 3 is a very different-looking bird, with a noticeable greyish-blue tone. (Craig Brelsford)

Intermediate forms (3a) are trickier. They may be purebreds showing random color variation or hybrids. The breeding ranges of leucogenis and salangensis partly overlap, with salangensis breeding in south-central China (mainly or exclusively south of the Yangtze River) and leucogenis breeding over a broad swath of eastern and central China from Sichuan east to Shandong and as far south as Guangdong.

Many thanks to Shanghai Birding member Jonathan Martinez. Martinez lives in Shenzhen and is an expert on the birds of southeast China. He was the first to point out that the photos of Ashy Drongo being posted on the Shanghai Birding WeChat group were of salangensis. He also was instrumental in our identification of the melanistic form of Long-tailed Shrike, discussed below. Thanks also to Paul Holt, who offered his opinion on the breeding range of leucogenis, and to Kai Pflug, for yet another useful photo.

103 SPECIES ON 15-16 OCT. 2016

Dusky Long-tailed Shrike, Hengsha, 16 Oct. 2016. Note that Dusky is not a subspecies but a color morph within Lanius schach schach, the same taxon found in Shanghai. The melanistic morph, however, is rare in Shanghai. Shanghai Birding member Jonathan Martinez reports that the form is ‘common’ in Guangdong, where the French birder resides. Martinez writes, ‘I’ve seen them in Jiangxi, Fujian, and coastal Guangxi. A bird turning up in Shanghai could be evidence of short-distance movements.’ (Craig Brelsford)

Partnering with visiting U.S. birder Bryce Harrison, Elaine Du and I noted 103 species over the weekend of Sat. 15 Oct. and Sun. 16 Oct. 2016. We covered the three main birding areas in Shanghai: Nanhui, eastern Chongming Island, and the reclaimed areas of Hengsha Island.

At Nanhui on Saturday we found Nordmann’s Greenshank, 24 Black-faced Spoonbill, 4 Mandarin Duck, and the Ashy Drongo. On Sunday on Hengsha we found a dark-morph Long-tailed Shrike, rare in Shanghai.

Black-faced Spoonbill (L) and Eurasian Spoonbill, Nanhui, 15 Oct. 2016. In the Shanghai region, the two species often are found together.
Black-faced Spoonbill (L) and Eurasian Spoonbill, Nanhui, 15 Oct. 2016. In the Shanghai region, the two species often are found together. Though not under quite as much pressure as Nordmann’s Greenshank and Spoon-billed Sandpiper, Platalea minor is nonetheless listed by the IUCN as endangered. Throughout the winter, Black-faced Spoonbill are consistently seen at Nanhui. (Craig Brelsford)

Nanhui also gave us Japanese Quail, Purple Heron, 6 Eurasian Spoonbill, 6 Black-tailed Godwit, and a Eurasian Woodcock at the Magic GPS Point (30.880563, 121.964551). We must have stumbled blindly past the well-camouflaged woodcock half a dozen times before finally flushing it. Also 4 Japanese Paradise Flycatcher, 2 Asian Stubtail, 2 first-of-season Red-flanked Bluetail, 2 Japanese Thrush, and 3 Eyebrowed Thrush.

Hengsha yielded Striated Heron, Pied Harrier, Eastern Marsh Harrier, Hen Harrier, Merlin, 9 Black-browed Reed Warbler, and our season’s first taivana Eastern Yellow Wagtail.

We found Eurasian Wryneck at Nanhui and on Hengsha and Bull-headed Shrike and Yellow-bellied Tit at Nanhui and on Chongming.

Nordmann’s Greenshank was roosting at nearly the same spot (30.920549, 121.963247) as a month ago. The endangered bird was among many Common Greenshank, allowing us to appreciate the former’s more obviously bi-colored bill, shorter legs, and more hunched appearance. The bird clearly stood out from among its Common cousins. For more on Nordmann’s ID, please see our Sept. 18 post, Your Handy-Dandy Nordmann’s Greenshank ID Primer.

The Black-faced Spoonbill were just a few hundred meters from the Nordmann’s in the defunct nature reserve. Poignantly, the spoonbills were roosting near the decrepit old sign introducing Platalea minor to the world.

Crow-billed Drongo, First Record for Shanghai

Editor’s note: The image above shows Crow-billed Drongo (left) and Black Drongo. The former was noted in Shanghai on Tues. 11 Oct. 2016, a first for the city. The latter is a common passage migrant in Shanghai. In this post, I show you how to separate the two species.

On Tues. 11 Oct. 2016 at Nanhui, Shanghai’s major birding spot on the East China Sea, Shanghai Birding member kaca found a first-winter Crow-billed Drongo Dicrurus annectans. kaca’s record was the first for Crow-billed Drongo in Shanghai.

Is kaca’s historic discovery a one-off, or is it the result of more birders with greater skills more thoroughly covering Shanghai’s hot spots and communicating more readily with one another? If the answer is the latter, then there may be a Crow-billed Drongo in your future! To sift out Crow-billed from the many Black Drongo in our area, note the following:

Crow-billed Drongo, Nanhui, 11 Oct. 2016. First record for Shanghai. Photos © 2016 by kaca and generously shared by him with shanghaibirding.com.
Crow-billed Drongo Dicrurus annectans, Nanhui, 11 Oct. 2016. First record for Shanghai. Photos © 2016 by kaca. Used with permission—and gratitude.

All drongos have a strong, black bill. Crow-billed (Panel 2a, above) may have the stoutest, as deep at its base as it is wide.

The swollen look of its bill may be Crow-billed’s most striking feature. The bill of Black Drongo Dicrurus macrocercus cathoecus is broad and short but noticeably less thick-based than that of Crow-billed. Compare bills of the two species in the image at the top of this post. (Race cathoecus is the form of Black Drongo birders are most likely to see in Shanghai.)

The iris in kaca’s first-winter Crow-billed is reddish-brown (2a). Adult Crow-billed has a blood-red iris.

Compare brown iris of adult Black at top of post.

Black Drongo often shows white spot at gape, never present in Crow-billed.

Note again the photo leading off this post.

First-winter Crow-billed shows white spotting from breast to undertail coverts (2b, 3).

First-winter Black, by contrast, shows more patchily white underparts (panels 1a, 1b in photo below).

The tail of Crow-billed shows a less shallow fork than the tail of Black. On average, the tail of Black is forked about twice as deeply as that of Crow-billed.

Compare Panel 4 in photo above to Panel 2 in photo below. Adult Crow-billed and Black have deeper forks, but the proportions are the same as in the sub-adults. In addition, the outer rectrices of Crow-billed’s tail are more likely to curl upward.

BACKGROUND ON THE SPECIES

A monotypic species, Crow-billed Drongo Dicrurus annectans breeds from the Himalayan foothills in India east to Hainan. In winter some birds go as far south as Sumatra and Java. Shenzhen-based French birder Jonathan Martinez, an expert on southeast China birds, reports breeding populations of Crow-billed in northern Guangdong and southwest Hunan. There are coastal records, most likely of migrants, from Hong Kong and Guangxi. Shanghai Birding member Paul Holt writes that Crow-billed is “undoubtedly overlooked” in southern China and “is probably quite rare or at least very localized.” Martinez agrees, calling Crow-billed “scarce” even at the Guangdong and Hunan sites.

On Tuesday I arrived in Nanhui too late to see Crow-billed Drongo. My partners Kai Pflug and Elaine Du and I made the fateful decision to cover Hengsha Island in the morning. The alluvial island at the mouth of the Yangtze was decidedly humdrum, with Far Eastern Curlew out on the mud along with 2 Sanderling and a Ruddy Turnstone. The huge new tree plantation on the island failed to deliver any forest birds beyond a single Asian Brown Flycatcher. There was a good count (17) of Richard’s Pipit.

We arrived in Nanhui and found kaca, who mentioned an unusual drongo he had seen that morning. We kept our eyes peeled for dark drongos, finding none. Our Nanhui harvest was limited to expected October birds such as Grey-backed Thrush (6) and Eyebrowed Thrush (2). Asian Brown Flycatcher (26) seemed to be on every tree.

All of Shanghai’s Big 5 Leaf Warblers were present: Pallas’s Leaf Warbler (1), Yellow-browed Warbler (1), Arctic-type Warbler (2), Pale-legged/Sakhalin Leaf Warbler (7), and Eastern Crowned Warbler (2).

We had 3 Japanese Paradise Flycatcher, Elaine’s and my season’s first Daurian Redstart, Asian Stubtail, and Rufous-tailed Robin.

I’m trying to get over missing the Crow-billed Drongo. I tell myself, “That’s birding,” but those words can’t fully dispel the empty feeling.

I am however happy for kaca, and I am encouraged, because the growing fluidity in reporting is leading to ever more astounding new bird records for Shanghai.

Pale-legged Leaf Warbler & the Shanghai Big 5

Editor’s note: The illustration above shows Shanghai’s Big 5 Leaf Warblers: Pale-legged Leaf Warbler (1), Arctic Warbler (2), Eastern Crowned Warbler (3), Pallas’s Leaf Warbler (4), and Yellow-browed Warbler (5). In this post, I tell you how to separate Pale-legged and its lookalike Sakhalin Leaf Warbler from the others.

Last Sat. 24 Sept. 2016 at Nanhui, my object of observation was Pale-legged Leaf Warbler, one of the Big 5 Leaf Warblers in the Shanghai region. In both spring and autumn, Phylloscopus tenellipes passes through Earth’s greatest city in considerable numbers, giving Shanghai birders ample opportunity to study it. A lookalike species, Sakhalin Leaf Warbler P. borealoides, also has been noted in Shanghai.

In this post, I shall outline the difficulty of distinguishing Pale-legged Leaf Warbler from Sakhalin Leaf Warbler on anything but song, and I will show you some of the traits of “Pale-Sak” that set this species pair apart from other leaf warblers. I also have a roundup of the other birds I noted this past Saturday.

ONLY SONG CAN SAFELY SEPARATE PALE-LEGGED FROM SAKHALIN

Per's PDF, page 11
‘Almost identical’: that’s the judgment of leaf-warbler expert Per Alström on Pale-legged and Sakhalin Leaf Warbler. The page shown here is No. 11 of a 40-page PDF on leaf warblers in China that Professor Alström wrote in 2012. The PDF is a handy introduction to a difficult group and can be downloaded here (13 MB).

Pale-legged Leaf Warbler is safely separable from Sakhalin Leaf Warbler only by song. Every other trait of each can occur in the other. Numerous authorities confirm this. Swedish ornithologist Per Alström calls the two species “almost identical” and “virtually indistinguishable except by song” (1). Mark Brazil says field separation of Pale-Sak is “uncertain,” and he warns readers to “beware light conditions” (2). P. Clement writes that Pale-legged and Sakhalin are “very similar” and claims, dubiously, that the latter is distinguishable from the former “mainly by greener upperparts and lack of wingbars” (3). Clements goes on to describe juvenile Pale-legged as being “more greenish on upperparts,” which begs the question of whether the greenish Pale-Sak one is observing is an adult Sakhalin or a juvenile Pale-legged. Moreover, a quick look at Oriental Bird Images shows many Sakhalin Leaf Warbler with wing bars.

Thankfully for us birders, the songs of the two species are distinctive and provide the basis for a safe ID. The song of Pale-legged, occasionally heard in Shanghai in May, is a cricket-like trill, that of Sakhalin a high-pitched, three-note whistle.

Sakhalin Leaf Warbler, Zhongshan Park, Shanghai, 5 May 2016 (00:36; 2.2 MB)

One day last May, I heard Pale-legged and Sakhalin singing together in Zhongshan Park—proof that Sakhalin passes through Shanghai. Usually, however, birders here are forced to perform the less than satisfying task of assigning the individuals they see to the category “Pale-legged/Sakhalin Leaf Warbler.”

Bottom line: In Shanghai, any Pale-Sak one sees is probably Pale-legged Leaf Warbler, the continental breeder, and not Sakhalin Leaf Warbler, the breeder from the eponymous Russian island plus Hokkaido and Honshu; but to claim certainty about any non-singing individual is the taxonomical version of Russian roulette.

DISTINGUISHING PALE-SAK FROM OTHER LEAF WARBLERS

The Pale-Sak species pair is readily distinguishable from other leaf warblers, in particular the other four members of Shanghai’s Big 5: Pallas’s Leaf Warbler Phylloscopus proregulus, Yellow-browed Warbler P. inornatus, Arctic Warbler P. borealis, and Eastern Crowned Warbler P. coronatus.

Here are a few principles:

Pale-legged Leaf Warbler and Sakhalin Leaf Warbler are plain, mid-sized to large leaf warblers without even the hint of a coronal stripe.

Pale-legged/Sakhalin has no crown stripe.
Pale-legged/Sakhalin Leaf Warbler shows no trace of a crown stripe (Panel 1). Yellow-browed Warbler usually shows a faint stripe (2). In Eastern Crowned Warbler (3) and Pallas’s Leaf Warbler (4), the stripe is prominent. (Craig Brelsford)

Pale-legged/Sakhalin Leaf Warbler has distinctive pink legs and a short bill with a black smudge on the lower mandible, which is pink at the base and tip.

Bill and legs of Pale-legged Leaf Warbler compared to those of Arctic Leaf Warbler.
Like Pale-legged/Sakhalin Leaf Warbler, species in the Arctic Warbler Complex lack a crown stripe and usually show one or two wing bars. One way to distinguish birds from the two groups is by the color of the legs and bill. The legs (Panel 1) of Pale-legged/Sakhalin Leaf Warbler are distinctively pale and pink, in contrast to the brownish-yellow legs of the Arctic-type Warbler in 2. Likewise, the slightly shorter bill of Pale-legged/Sakhalin (3) shows a blackish upper mandible and pinkish lower mandible and cutting edge. The black smudge on the lower mandible does not reach the tip. The bill of Arctic-type Warbler (4) follows a similar pattern, but with brownish-yellow replacing pink. (Craig Brelsford)

Even on a fast-moving Pale-Sak in poor light, the pink of the bill and especially of the legs is readily seen. The distinctive pale color of these bare parts is a handy tool for distinguishing Pale-Sak from birds in the Arctic Warbler Complex, which like Pale-Sak lack a crown stripe and usually show one or two wing bars. (The Arctic Warbler Complex consists of Arctic Warbler Phylloscopus borealis, Kamchatka Leaf Warbler P. examinandus, and Japanese Leaf Warbler P. xanthodryas. In Shanghai, Arctic Warbler is the most common of the three, migrating through Shanghai every spring and autumn.) The pink coloration also distinguishes Pale-Sak from Dusky Warbler P. fuscatus, an uncommon migrant and winter visitor in Shanghai, and the scarce passage migrant Two-barred Warbler P. plumbeitarsus.

Pale-legged/Sakhalin Leaf Warbler constantly pumps its tail.

The tail of Pale-legged/Sakhalin Leaf Warbler pumps independently of other muscular actions.
The tail of Pale-legged/Sakhalin Leaf Warbler pumps independently of other muscular actions. In panels 1-2, note that the tail pumps even as the warbler devours an insect. Panels 3-4 show the warbler motionless except for the up-and-down movement of the tail. Photos here and immediately below are of a single individual and were taken at Microforest 4 (30.953225, 121.959083), Nanhui, 24 Sept. 2016. (Craig Brelsford)

The tail-pumping of Pale-legged/Sakhalin is one of the most distinctive behavioral traits of the species pair. The steady movement usually occurs independently of other muscular actions and is slow enough for the eye to see. The tail-flicking of Arctic Warbler, by contrast, is more spasmodic and is often accompanied by wing-flicking.

Pale-legged/Sakhalin Leaf Warbler is often found on the lower, thicker branches of trees.

Pale-legged/Sakhalin Leaf Warbler on thick branch.
Pale-legged/Sakhalin Leaf Warbler on thick branch. More so than other leaf warblers, Pale-Sak is likely to be seen on leafless, thick branches low on the tree. (Craig Brelsford)

With its ability to forage along thick branches and not just glean from the underside of leaves, Pale-legged/Sakhalin can remind one of a nuthatch. Other species such as Arctic Warbler use the lower branches, but sustained observation shows Pale-Sak more often in those areas. Note: In May and June 2016, I studied Pale-legged Leaf Warbler on its breeding grounds in Heilongjiang. There, amid trees older and taller than one usually sees in Shanghai, I most often noted the species far above my head, in the mid-canopy.

A NOTE ON CALLS

Except for the silent migrant Eastern Crowned Warbler, Shanghai’s Big 5 Leaf Warblers all call in both spring and autumn. The calls are distinctive. The metallic “tink” of Pale-Sak contrasts markedly with the “tzit” of Arctic Warbler, the “dweet” of Pallas’s Leaf Warbler, and the “sweet” of Yellow-browed Warbler.

Pale-legged/Sakhalin Leaf Warbler, Nanhui, Shanghai, 8 May 2016 (00:15; 1.4 MB)

Yellow-browed Warbler, Lesser Yangshan Island, Zhejiang, 24 April 2014 (00:07; 1.7 MB)

Note that, according to Brazil, the call of Pale-Sak only can separate the pair from other species. It cannot be used to separate Pale-legged from Sakhalin. The tink of Pale-legged, Brazil writes, “is probably indistinguishable from Sakhalin Leaf” (2).

UPDATE: 19 OCT. 2016

Editor’s note: This post caught the attention of Philip D. Round, a professor at Mahidol University in Bangkok and an expert on leaf warblers. In an e-mail written 18 Oct. 2016, Round writes that as discoveries are made and papers published, separating Pale-legged Leaf Warbler from Sakhalin Leaf Warbler on call may become more widespread. Separation on morphology, by contrast, will be much more difficult, though it may eventually turn out to be possible in the hand.

The following paragraphs are from Round’s e-mail to me:

“I enclose a paper that details the first records of both Kamchatka Leaf Warbler and Sakhalin Leaf Warbler from Thailand. [Editor’s note: the paper, “Addition of Kamchatka Leaf Warbler Phylloscopus examinandus and Sakhalin Leaf Warbler P. borealoides to Thailand’s Avifauna,” is available for download through shanghaibirding.com (708 KB).] This has been rather overtaken by events, as we have now caught into the hundreds of Sakhalin LW, mostly on spring passage, and quite a few more Kamchatka. I have an undergraduate student who has carried out DNA assay on about ten percent of all the Pale-legged and Sakhalin LW caught. For many of these we have also recorded call notes on release. When she comes back from overseas study in January 2017 I hope we’ll get a paper out which publishes details of call-note frequency and DNA results for this large sample, which should show the correlation between species and call-note frequency clearly. (Actually this is moderately and anecdotally well-known already. I think either Frank Lambert or Jonathan Martinez was the first to draw my attention to the difference, and it is mentioned by Yap et al. in BirdingASIA with reference to an overwintering Singapore bird.) [Note: Round is referring to Yap, Francis et al., “First wintering record of the Sakhalin Leaf Warbler Phylloscopus borealoides in South-East Asia, with notes on vocalisations,” BirdingASIA 21 (2014): 76–81.]

“I am a bit less sanguine on finding means (other than by call frequency or song) to separate all birds. Even in the hand, it is by no means clear. We can pick out long-winged male Sakhalin, and short-winged female Pale-legged. But there is more overlap than previously realized, and most are in between. There don’t appear to be any 100% consistent wing-formula differences, and plumage and bare-part features, while somewhat indicative, are again less than 100% reliable—especially under field conditions. But probably we are missing something. The next thing to do is to apply PCA or some other multivariate analysis to figure out reliable means of separation of birds in the hand from our large sample, and also to use the information we have to figure out differences in the timing of passage of the two spp.”

ROUNDUP FOR SATURDAY 24 SEPT. 2016

Microforest 4
Microforest 4 (30.953225, 121.959083), Sat. 24 Sept. 2016. This is the largest of the eight microforests at Cape Nanhui and an astonishingly effective migrant trap. With woodland birds migrating through and trees all around, one almost begins to forget that this speck of woodland is just a stone’s throw from the mudflats and the East China Sea. German birder Kai Pflug recently carted out trash from the wood, enhancing its allure. (Craig Brelsford)

Stimulating discussions about leaf warblers enlivened the lulls on a day in which my wife Elaine Du and I once again partnered with veteran British birder Michael Grunwell. We noted 69 species, starting at the sod farm south of Pudong airport then spending the rest of the day at Nanhui. We reunited briefly with the Sino-German birding duo of Xueping and Stephan Popp, and we met Dutch birder Benjamin Muis. Highlights:

Ruff

Note the scaly upperparts and buffy head of this juvenile Ruff, as well as the white sides to its tail. Elaine got these shots with my iPhone 6 plus Swarovski ATX-95 spotting scope mounted atop our Manfrotto head and Gitzo tripod. (Elaine Du)

Juvenile spotted on mudflats at high tide. A far-northern, trans-Eurasian breeder, Philomachus pugnax is a scarce passage migrant in Shanghai. Amid the greenshanks and godwits, the Ruff stood out with its buff-washed head and scaly upperparts. Juvenile Ruff resembles Buff-breasted Sandpiper, a much smaller American bird that we quickly ruled out.

A Bit of Lapland in Shanghai

On 30-31 Jan., Elaine and I noted 75 species at Nanhui, Hengsha, and Chongming. We had 6 Lapland Longspur on Chongming and 50 Mew Gull at Nanhui. The pair of Cinereous Vulture remain on Chongming, and we saw a good portion (65) of the Hooded Crane wintering on the great alluvial island. Red-throated Loon was still at Nanhui, and Dishui Lake once again held Greater Scaup (8), Common Goldeneye, and Horned Grebe (3). We had an impressive 350 Northern Pintail in the sea off Nanhui, and though numbers of Gadwall (590) and Falcated Duck (720) were lower than in November, the species maintain a sizable presence on Hengsha.

Lapland Longspur, Chongming, Shanghai, 31 Jan. 2016.

The longspurs appeared late Sunday, just as snow was starting to fall. The inclement weather must have upset the Buff-bellied Pipit, Eurasian Skylark, and Eurasian Tree Sparrow using the recently plowed fields. Suddenly birds were flying everywhere. The grey sky made visual ID difficult, but some of the birds were calling and identifiable by call. But not all; so I took a flurry of record shots. In one series of images was a bird I had never seen before. I sent some of the images to Jan-Erik Nilsén, who told me that the facial pattern was typical of Lapland Longspur. And so it was. MacKinnon says Calcarius lapponicus “winters in small numbers along bare meadows along E coast between 30° and 40° N and along Changjiang River”; that is a box into which our situation neatly fits.

This 3-species-in-1 image shows 2 Kamchatka Gull (bottom L, top R), Vega Gull (large gull in middle), and Black-headed Gull (bottom R). Note the 'kinder' look of Larus canus kamtschatschensis; its more rounded head, in contrast to the more gently sloping forehead of the Vega; and its smaller size in comparison to Vega. Nanhui, 30 Jan. 2016.

Nanhui, 30 Jan. 2016.

The views of Mew Gull Larus canus came about because of preparation and luck. Ever since Michael Grunwell moved to Shanghai last year, he has been telling me to look for Mew Gull in Shanghai; he was sure it would show up here in winter. Bolstering that suspicion was a recent report from Jonathan Martinez of Mew Gull in Guangdong.

Kamchatka Gull Larus canus kamtschatschensis, Nanhui, 30 Jan. 2016. L. c. kamtschatschensis is larger and darker than the western forms L. c. canus and L. c. heinei. L. c. heinei is known to occur on the China coast and should be looked out for.

At Nanhui, gulls usually appear here and there. On Saturday, Elaine and I finally had a chance to view a large group. An afternoon tide was coming in just right, boxing about 300 gulls into a corner of the sea wall. Elaine and I were waiting with camera and spotting scope. “This is the day!” I said. Sure enough, among the dozens of Vega Gull and Black-headed Gull was a sizable element of Mew. We quickly distinguished them from the much larger Vega. The Mew we photographed seem to have a squarer head and beadier eye than would be the case with race heinei; we therefore believe our gulls are Kamchatka Gull Larus canus kamtschatschensis.

The Red-throated Loon was in the large pond behind the Holiday Inn and Magic Parking Lot. Elaine found it doing the scan. Six days earlier, we had 3 Red-throated Loon in a pond a few kilometers north. Around 500 of our Great Cormorant were perching on the giant ring in the middle of Dishui Lake. Driving along the sea wall, we saw a Red-throated Pipit eating seeds left over from the rice harvest, and in the mud below we found three bright-yellow taivana Eastern Yellow Wagtail.

Rather than drive back to the city, Elaine and I drove straight to Changxing Island and took the ferry to Hengsha. We spent Saturday night at Héngshā Bànrìxián Mínsù (横沙半日闲民宿; +86 135-0185-1814 and +86 150-2164-5467; 120 yuan).

Sunday brought 56 species on Hengsha and Chongming. Our stay of a little more than five hours on Hengsha revealed no extraordinary birds. Eurasian Bittern were unusually visible; 3 of the 5 we noted were standing more or less in the open.

We took the ferry back to Changxing Island, and there, sitting in traffic, I happened to look out the window of our Skoda Scout and saw 3 Goldcrest. We took the Shanghai-Changjiang Bridge across the Yangtze to Chongming.

After more than two weeks on Chongming, our Cinereous Vulture appear to be doing fine. Here they were yesterday.
After more than two weeks on Chongming, our Cinereous Vulture appear to be doing fine. Here they were yesterday.

The Cinereous Vulture were a few kilometers south of the place where we had found them eight days earlier. As before, the vultures were standing on an earthen bank along the first row of fields behind the canal at the base of the sea wall. Nearby were the Hooded Crane and 21 Common Crane. The cold, grey day was enlivened by a colorful flock of 55 Grey-capped Greenfinch.

Mew Gull and Lapland Longspur became the 267th and 268th species of bird Elaine and I have noted in the Shanghai region since 11 Sept. 2015.
