Swinhoe’s Rail in Shanghai

The rarities just keep on coming here in Shanghai. The latest is Swinhoe’s Rail, seen at the Magic Parking Lot in Nanhui on Sat. 29 Oct. 2016 by a trio of Shanghai bird photographers. The photo above was taken by one of the three, Chén Qí (陈骐).

This amazing find comes on the heels of Shanghai’s first record of Crow-billed Drongo on 11 Oct. and Pomarine Skua on 19 Oct. What a birding month October 2016 was in Earth’s largest city!

I got the news about the rail from Chén Qí’s wife, Wāng Yàjīng (汪亚菁). Near dark, as I was returning home after my own eventful day at Nanhui, Wāng Yàjīng called me to report that she had just seen a strange bird. The bird, Yàjīng said, popped its head out of the bushes at the well-known photographers’ setup at the edge of the lot. It showed half its body and disappeared. The episode lasted a few seconds, Yàjīng said.

One look at the photo Yàjīng sent me, and there was no doubt: Swinhoe’s Rail.

The smallest rail in the world, Swinhoe’s Rail is also one of the least-known. The IUCN lists it as Vulnerable.

On Sun. 30 Oct. 2016, photographers maintaining a long vigil saw the rail again.

ANOTHER UNUSUAL SIGHTING: BLACK-NAPED MONARCH

The next day, Sun. 30 Oct. 2016, Kai Pflug found Black-naped Monarch at Wusong-Paotaiwan Wetland Park in Shanghai. Kai was acting on information from Chinese bird photographers who had discovered the bird earlier. The monarch is almost certainly wild. It is a first-winter bird, not the more beautiful adult male that presumably would be of greater interest to collectors, and in Kai’s photos one sees none of the damage common to birds kept in a cage.

Black-naped Monarch has been noted in Shanghai before, most recently on 2 Nov. 2014 by Stephan Popp and Xueping Popp. In China, H. a. styani usually ventures no further north than Guangdong. H. a. oberholseri is resident in Taiwan.

You know your birding area is rich when Nordmann’s Greenshank fails to capture the headline. On Sat. 29 Oct. 2016, the day the Swinhoe’s Rail electrified Shanghai birders, my partners Michael Grunwell, Elaine Du, and I spotted the Endangered Nordmann’s in the defunct nature reserve (30.920500, 121.973167) at Nanhui, near the skua site at 30.923915, 121.954738. We speculate that Saturday’s adult-winter Nordmann’s is the same individual we saw in the area on 15 Oct. and 20 Oct. and possibly as far back as 17 Sept. and 3 Sept.

Other highlights Saturday were 54 Endangered Black-faced Spoonbill found exclusively in the defunct nature reserve, further underscoring the critical importance of that highly threatened parcel of land. Joining Nordmann’s in the high-tide roost were 2 Ruff, a Near Threatened Red Knot, and 2 of our day’s 4 Saunders’s Gull, a Vulnerable species uncommon in Shanghai.

We had Japanese Grosbeak in Microforest 8 and Long-eared Owl at the Magic GPS Point (30.880563, 121.964551). Among our season’s firsts were 2 Tundra Bean Goose, Black-necked Grebe, 5 Goldcrest, Manchurian/Japanese Bush Warbler, 3 Brown-flanked Bush Warbler, and 2 Dusky Thrush. Buntings finally are arriving in numbers, with Yellow-throated Bunting (16) and Chestnut Bunting (3) debuting on our Autumn 2016 list. We had a lucky 88 species in all.

Throughout the day, the effectiveness of the Nanhui microforests was on display at Microforest 1 (30.923889, 121.971635). The tiny wood, which we visited off and on, was hopping with hungry migrants, grounded on a breezy day. Brambling, Daurian Redstart, and Yellow-bellied Tit were the tamest, but as the day wore on even shy species such as Japanese Thrush, Grey-backed Thrush, and Black-winged Cuckooshrike were coming out into the open. Photographers were present, but no one was using mealworms; the forest birds were attracted solely to the habitat offered by a stand of trees no bigger than a tennis court.

Two East Asian species of Turdus thrush in Microforest 1. 1a-1c: Japanese Thrush Turdus cardis, male. 2, 3a, 4a: Japanese Thrush, female. 3b, 4b: Grey-backed Thrush T. hortulorum. Male T. cardis distinguished from Chinese Blackbird T. mandarinus by smaller size and white belly covered with black arrowheads. Japanese and Grey-backed females are harder to separate (3a, 3b), in part because both are shy and rarely come into the open. In Japanese, the arrowheads run farther down the flanks (4a) than in Grey-backed (4b). 4a: Nanhui, 7 Nov. 2015. 4b: Yangkou, Jiangsu, 4 Oct. 2013. All others Microforest 1, Nanhui, 29 Oct. 2016. All by Craig Brelsford.

Other microforests held Eurasian Woodcock, Japanese Paradise Flycatcher, Rufous-tailed Robin, Taiga Flycatcher, and White’s Thrush, Eyebrowed Thrush, and Pale Thrush. Dark-sided Flycatcher and Siberian Rubythroat were at the Magic Parking Lot (30.884898, 121.968229), Asian Stubtail at the Magic GPS Point.

We netted season’s first Buff-bellied Pipit during a 35-minute stop at the sod farm near Pudong Airport (31.112586, 121.824742). Red-throated Pipit were present in smaller numbers (3) than six days earlier.

Brambling, Nanhui, Shanghai, 29 Oct. 2016. (Craig Brelsford)
Brambling, Nanhui, 29 Oct. 2016. We found these birds in Microforest 1 (30.923889, 121.971635). Famished after the long flight south, the bramblings were very tame, allowing me to get these close-ups. Male Fringilla montifringilla (R) shows marked variation between breeding and non-breeding plumage; the female (L) shows less. All plumages show a white rump (L). Breeding male has an all-black bill, but in winter the bill is yellow with a black tip, like the female. The glossy blue-black head of breeding male becomes rusty-fringed in winter. Brambling breed across Eurasia and are present throughout the winter in Shanghai. (Craig Brelsford)

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 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.

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

Long-tailed Shrike dusky morph, Hengsha, 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.’

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.

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.

Bull-headed Shrike Lanius bucephalus bucephalus, Nanhui. Outside the breeding season, the pale base to the lower mandible (inset) is present on both sexes of the nominate subspecies. This is an adult female. Note the lack of a black facial mask and the striking rusty-orange coloration. The nominate race breeds in northeast China, the Russian Far East and adjacent islands, Korea, and Japan and is a passage migrant in Shanghai. A little-known western subspecies, sicarius, breeds in Gansu and lacks the pale base to the lower mandible.

This line of trees (31.216753, 121.408195) is wedged between two housing complexes near my apartment in Changning District, Shanghai. Deep in the bowels of Earth’s largest city, this spot is as urban as urban can be. The trees, however, are tall and provide a large surface area for wild birds. On 17 Oct. 2016, I found Oriental Magpie-Robin and Japanese Tit there, and on 14 Oct. I found a fast-moving flock of Japanese White-eye. Chinese Blackbird breed in the area, and Siberian Weasel have been noted in the vicinity.

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.

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.

ID Workshop: Paradise Flycatchers

Editor’s note: The featured image above shows the stunning male Japanese Paradise Flycatcher and serves to introduce this week’s theme: How can birders tell apart the two species of the remarkable genus Terpsiphone that migrate through Shanghai?

Each spring and autumn, two species of paradise flycatcher pass through Earth’s greatest city: Japanese Paradise Flycatcher Terpsiphone atrocaudata atrocaudata and Amur Paradise Flycatcher T. incei. The two species can seem confusingly similar, especially in the poor light of a wood. With a little practice you can tell the males apart, and with a lot of practice you should be able to separate the females. Here is what you need to know:

If in Shanghai you see a white-morph paradise flycatcher, then by definition you are not looking at Japanese Paradise Flycatcher, and you are almost certainly looking at Amur Paradise Flycatcher.

L: Amur Paradise Flycatcher, white morph, Nanhui. By Kai Pflug. R: same, Dongzhai, by Craig Brelsford.
Two images of Amur Paradise Flycatcher Terpsiphone incei, white morph. L: Nanhui, Shanghai, 30 May 2016 (Kai Pflug). R: Dongzhai National Nature Reserve, Henan, 5 June 2010 (Craig Brelsford). Most Amur males are rufous, but a certain percentage are white. Japanese Paradise Flycatcher T. atrocaudata has no white morph.

No white morph exists in Japanese (Mark Brazil, Birds of East Asia). Regarding Amur, among my sources only Brazil expresses doubt about the existence of a white morph. shanghaibirding.com contributor John MacKinnon (A Field Guide to the Birds of China) and C.W. Moeliker (Handbook of the Birds of the World, Vol. 11) assure us that Amur white morph does exist. MacKinnon says that Amur white morph accounts for less than half of adult males.

We know that Amur white morph exists because we have seen it ourselves. On 30 May 2016, Kai Pflug photographed an Amur white morph at Nanhui, the coastal birding site in Shanghai. In May 2010 at Dongzhai, Henan, 680 km inland from Shanghai, I found an Amur white morph.

Could a white morph from a third species occur in Shanghai? Although the movements of paradise flycatchers are “complex and not fully understood” (Moeliker), I think we can presume that it is unlikely. The nearest third species is Oriental Paradise Flycatcher T. affinis saturatior, which according to MacKinnon winters no closer to Shanghai than Guangdong.

The mantle, wings, rump, and tail of rufous-morph male Amur are rufous-brown; in Japanese, the mantle, wings, and rump are purplish-brown, and the tail is black.

Top: Amur (Kai Pflug). Bottom: Japanese (Craig Brelsford).
In Amur male (top), the mantle, wings, rump and tail are rufous-brown. Japanese male has purplish-brown mantle, wings, and rump and a contrasting black tail. Amur: Nanhui, June 2016 (Kai Pflug). Japanese: Yangkou, Jiangsu, 2 May 2012 (Craig Brelsford).

The pictures speak for themselves. In good light you should have little trouble telling the two apart. The cinnamon tones of Amur are often what Shanghai birders notice first.

Male Japanese has a black head and a black breast, forming a large hood. Amur rufous morph has black head and grey breast, forming a two-tone hood.

Comparison of hoods of Japanaese Paradise Flycatcher and Amur Paradise Flycatcher. Top 2: Craig Brelsford. Bottom 2: Kai Pflug.
In Japanese (top two photos), the black head and throat seamlessly meet the black breast, forming an oversized hood. (Note however some grey feathers in the worn spring Japanese male top left.) By comparison, the black head of Amur (bottom photos) contrasts with its grey breast. Japanese: Yangkou, 2 May 2012 (top left) and Nanhui, 17 Sept. 2016 (top right); both by Craig Brelsford. Amur: both Nanhui, June 2016 (Kai Pflug).

The hood of Amur has in addition more of a bluish tint than that of Japanese. Note the blue tint in the hood of Amur bottom left. Note also that the cobalt-blue eye ring of Japanese (top left) tends to be larger than the eye ring of Amur.

The females require more care to separate. Be persistent, get a good view, and try to get a photo. Note the following:

Compared to Amur female, Japanese female has darker, duller, and less rufous mantle, wings, rump, and tail. Japanese has much darker (nearly all-black) flight feathers and sooty primary coverts.

Top: Japanese Paradise Flycatcher (Craig Brelsford). Bottom: Amur Paradise Flycatcher (Kai Pflug).
As with the males, female Japanese (top) is darker and less rufous than female Amur (bottom). Japanese: Yangkou, 30 Sept. 2013 (Craig Brelsford). Amur: Nanhui, May 2016 (Kai Pflug).

For the bit about the sooty primary coverts, I am indebted to David Gandy of Bangkok City Birding.

In their head and breast coloring, female Japanese and Amur show a pattern similar to that of the males. Whereas Japanese is more concolorous (panels 3 and 4), Amur shows more of a contrast between head and breast (1a, 1b, 2). Both Japanese and Amur female have whitish bellies, but the darker breast of Japanese contrasts more with the whitish belly than is the case with Amur. The head is glossier in Amur than in Japanese, whose crown is dull (inset, Panel 3). Japanese has faint rufous flanks, unlike Amur.

MAINLY SILENT IN SHANGHAI

In Shanghai, you will almost never hear a paradise flycatcher utter a sound. I have a single recording:

Japanese Paradise Flycatcher, call, Nanhui, 24 May 2016 (00:01; 848 KB)

BACKGROUND ON THE SPECIES

Japanese Paradise Flycatcher Terpsiphone atrocaudata and Amur Paradise Flycatcher T. incei breed farther north than any other species in their mainly tropical genus. T. atrocaudata atrocaudata breeds in Korea, Japan, and Taiwan and is highly migratory, wintering as far south as Sumatra. (Birds in Taiwan, however, are largely resident.) T. incei, a monotypic species, is also highly migratory, with a breeding range extending into the Russian Far East and wintering grounds as far south as Java (Moeliker). Japanese is listed by the IUCN as Near Threatened, mainly because of habitat loss on its wintering grounds.

While researching drongos, on 18 Oct. 2016 I discovered two more photos of female Amur Paradise Flycatcher. The photos above were taken 4 July 2009 at Laoshan (32.071265, 118.560699), a site in Nanjing, Jiangsu 290 km inland from Shanghai. Note again in this Amur the contrast between bluish-black head and bluish-grey breast, the poorly defined border between the bluish-grey breast and the whitish belly, the lack of rufous coloration on the flanks, and the rufous-brown upperparts and tail, obviously brighter than in Japanese Paradise Flycatcher.

Special thanks to Kai Pflug, who collaborated with me on this post, and without whose photos this post would not have been possible. Kai’s images of Amur Paradise Flycatcher, some of which are displayed above, are a valuable record of this poorly known species. I have published dozens of Kai’s photographs on shanghaibirding.com, and in September 2016 I wrote about his work cleaning up the litter at Nanhui. Kai is from Germany and lives in Shanghai. He is an active member of the Shanghai Birding WeChat group.
