Sakhalin Leaf Warbler at Century Park

​Century Park, Pudong, Thurs. 5 Oct. 2017, Komatsu Yasuhiko and Craig Brelsford, 39 species. Hiko and I blew past our target of 35 species and added three species to the shanghaibirding.com Century Park all-time bird list. The total now stands at 138 species. Hiko and I added five species to the eBird Century Park all-time list, bringing the total to 117.

The new entries on the shanghaibirding.com list are Sakhalin Leaf Warbler, Dusky Warbler, and White-throated Rock Thrush. The new entries on the eBird list are those three plus Japanese Paradise Flycatcher and Taiga Flycatcher.

“Century Park is getting better,” Hiko said. My young friend is right. Century Park is an island of stability amid the sea of change (mainly degradation) that is the natural environment of Shanghai. Ten years ago this month, when Hiko was a tyke of 6, I made my first visit to urban Shanghai’s best birding area. Little has changed. The biggest difference between October 2007 and October 2017 is, the trees are taller. The wooded areas at Century have an ever-stronger woodsy feel.

Notes:

— Century yielded yet another regional record of Sakhalin Leaf Warbler. Evidence is growing that in the Shanghai area this passage migrant has been neglected and is more common than previously thought. I recently wrote a series of posts, the latest being this one, on distinguishing Sakhalin Leaf Warbler from its sister species Pale-legged Leaf Warbler.

Here is the recording I made of the calling Sakhalin on Thurs. 5 Oct. Apart from a DNA assay, call as well as song is the only reliable way to separate Sakhalin Leaf Warbler from Pale-legged Leaf Warbler. At 4.9 kHz, the “tink” recorded below is a full kilohertz deeper than the call of Pale-legged Leaf Warbler.

Eurasian Woodcock whizzed overhead on its way to Bird Island (31.217405, 121.554936). The woodcock was going to the one best place for it in the urban park. Bird Island, Century’s sanctuary-within-a-sanctuary, is a bird-friendly, cat-free parcel of woodland cut off from the rest of the park by a moat.

Great Spotted Woodpecker used to be found mainly on Bird Island. On Thursday we found 2 in other sectors of the park. With the steadily improving woodland in the park, expect Great Spotted Woodpecker to be seen in more and more areas. Century Park is one of the few areas in urban Shanghai where woodpeckers are commonly found.

Arctic Warbler 9 calling. No evidence Thursday of Kamchatka Leaf Warbler.

Sakhalin Leaf Warbler in Shanghai: A Clearer Picture

On Sun. 17 Sept. 2017 at Pudong’s Cape Nanhui, I achieved a personal first: photos of an unmistakable Sakhalin Leaf Warbler Phylloscopus borealoides. As expected, the photos show a leaf warbler whose plumage and bare parts are virtually indistinguishable from those of Pale-legged Leaf Warbler P. tenellipes. Coupled, however, as they are with sound-recordings of the same individual, ensuring the ID, the photos constitute a rare visual record of Sakhalin Leaf Warbler in Shanghai.

The leaf warbler I found was easily identifiable as a member of the Pale-Sak species pair. It had strikingly pale pink tarsi, an olive-brown crown contrasting with olive-green mantle and wings, a long and creamy supercilium, and faint wing bars on the median and greater coverts.

The bird, which was in Microforest 1, behaved in a way typical of the Pale-Saks I have observed in the Cape Nanhui microforests, eight tiny woodlands that dot the coastline of the cape. Rarely venturing more than 2 m off the ground, the leaf warbler favored low branches and vines for browsing and sturdy low branches for perching. It pumped its tail steadily, called spontaneously, and upon hearing playback of its own call moved in to investigate the source.

Without recording the call of the leaf warbler (call as well as song being a diagnostic separator of Sakhalin and Pale-legged), would I have been able to get an ID? Almost certainly not, said leaf-warbler expert Phil Round:

“I am a bit less sanguine on finding means (other than call frequency or song) to separate all [Pale-Saks]. 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.” (Round, in litt., 2016; emphasis mine)

The most convenient separator of Pale-Sak is song, the cricket-like trill of Pale-legged being easily separable from the metallic whistle of Sakhalin. As Shanghai is not in the breeding range of either species, Pale-Sak songs are not often heard in Earth’s Greatest City. I have heard Sakhalin sing only once, on 5 May 2016 at Shanghai’s Zhongshan Park (Brelsford 2016). The song of Pale-legged I have heard at various locations in Shanghai as well as on its breeding grounds in Heilongjiang (Brelsford & Du 2017).

Although not as readily distinguishable as the songs, the “tink” calls of Pale-Sak differ markedly and consistently and are a reliable basis for an ID (Yap et al. 2014; Round et al. 2016; Weprincew et al. 1989). Yap et al. say the call of Pale-legged is of a “consistently higher frequency” than the call of Sakhalin. The calls that I have recorded of the two species show a difference in frequency of about 1 kHz, very much in line with others’ findings (Brelsford, August 2017; Brelsford, September 2017).

For birders unaccustomed to Pale-Sak calls, the difference may be hard to detect, especially at windy Cape Nanhui. A sound-recorder (which may be a smartphone) will pick up the difference, and an audio spectrogram will show it graphically. Solid, indisputable ticks, in some cases life ticks, await enterprising birders who sound-record.

In recent months, my work with sound-recordings has helped give Shanghai birders a clearer picture not only of Sakhalin Leaf Warbler but also of Kamchatka Leaf Warbler Phylloscopus examinandus, like Sakhalin a poorly known passage migrant through Shanghai (Brelsford, June 2017). In the case of Pale-Sak in Shanghai, a picture is emerging of overlapping migratory pathways. This finding comports with the findings of Yap et al. at Beidaihe, a thousand kilometers to the north. After analyzing calls obtained at Beidaihe of both Pale-legged and Sakhalin, Yap hypothesizes that in coastal Hebei “the migratory pathways of the two sister species may largely overlap” (2014).

How extensive is the Pale-Sak migratory overlap in Shanghai? How many of the Pale-Saks that we find in Shanghai each spring and autumn are Pale-legged, and how many are Sakhalin? Is there a peak passage time in Shanghai for each species, and if so, when is it?

Answers to these questions are currently unknown, but they are probably knowable, and it is very much possible for the citizen-scientists of Shanghai to be the producers of that knowledge. We only need to change our habits. When it comes to identifying lookalike species such as Pale-legged and Sakhalin Leaf Warbler, birders need to understand that photos do nothing to cut through the muddle. Only sound-recordings lead to indisputable records and a clearer picture of the species in Shanghai.

A clearer picture will add to our knowledge of the movement of leaf warblers along the central Chinese coast, focus attention on little-known East Asian species, and heighten the allure of Shanghai as a world-class birding location.

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.

Late Summer Shanghai

As summer melts into fall, Pudong’s Cape Nanhui continues to prove to be one of the best birding locations in China. In the period 26 Aug. to 8 Sept. 2017, I birded four days at the most southeasterly point of Shanghai, as well as at other key locations in Earth’s Greatest City. I noted 106 species.

Highlights were Brown-chested Jungle Flycatcher at Microforest 1, beautiful white-morph Amur Paradise Flycatcher at Binhai Forest Park, Fairy Pitta in the Cape Nanhui microforests, Greater Painted-snipe holding on in a canal near the coast, Asian Dowitcher at South Pond, Chinese Egret at North Pond and on South Beach, and Pacific Golden Plover at the sod farm south of Pudong Airport. Sakhalin Leaf Warbler and Pale-legged Leaf Warbler were calling in the Magic Parking Lot, and endangered Far Eastern Curlew and Great Knot were recorded at Nanhui. Crested Goshawk appeared in inner-city Zhongshan Park.

Here are some of the best birds:

Brown-chested Jungle Flycatcher
Cyornis brunneatus

Brown-chested Jungle Flycatcher, Microforest 1 (30.923889, 121.971635), 4 Sept. 2017. Cyornis brunneatus is a very scarce vagrant to Shanghai. The species breeds in southeast China and spends the winter in Malaysia and Indonesia. (Craig Brelsford)

After nearly 10 years in Shanghai and countless visits to Cape Nanhui, I still occasionally score life birds there, a testament to the richness of the hot spot. Such was the case 4 Sept. with Brown-chested Jungle Flycatcher. The bird, an adult, was in Microforest 1 (30.923889, 121.971635).

Brown-chested Jungle Flycatcher is a very scarce vagrant to Shanghai. Cyornis brunneatus breeds in southeast China and spends the winter in peninsular Malaysia, Sumatra, and Borneo. It is uncommon even in its core range and virtually unknown in the Shanghai region outside Cape Nanhui; the place closest to Shanghai where I have heard of it occurring is Emeifeng, 635 km southwest of Shanghai in Fujian.

The IUCN lists the species as Vulnerable because of the loss of mature primary lowland forest throughout its range.

Amur, Dongzhai, 2010. (C. Brelsford)

3 Amur found 27 Aug. at Binhai Forest Park, the heavily wooded green space near Cape Nanhui, 4.5 km inland from the East China Sea. A stunning white-morph male and rufous-morph were continuously together, and we found a single rufous-morph in another part of the park. The white-morph as well as the rufous-morph accompanying it were calling. I have seen dozens of paradise flycatchers in Shanghai over the years and heard only one call (a Japanese for 1 or 2 seconds). Why were the Amur at Binhai Forest Park calling?

Binhai Forest Park is visited little and birded even less; could this quiet, thickly wooded park hold breeding Amur Paradise Flycatcher? As the white-morph male looks like something out of a fairy tale and is a bird even a non-birder would recognize, I asked park employees whether they had seen it. All said no.

The white-morph Amur that U.S. birder Tom Hurley and I saw was only the second I had ever beheld and a first for me in Shanghai. At Dongzhai National Nature Reserve, Henan, on 5 June 2010, I photographed the white-morph shown right. The Binhai white-morph lacked the long tail feathers of the bird I saw at Dongzhai but was still an unforgettable sight.

Dorsal views of Amur (top) and Japanese Paradise Flycatcher. ​If the mantle, back, and tail have a purplish-brown hue, then you are likely looking at Japanese Paradise Flycatcher, known helpfully in Chinese as ‘Purple Paradise Flycatcher.’ If the upperparts are cinnamon-brown, then it is likely Amur. White-morph males are never Japanese, as the white morph does not occur in that species. 26-27 Aug. 2017, Cape Nanhui. For more on Amur-Japanese ID, see my post ‘ID Workshop: Paradise Flycatchers.’ (Craig Brelsford)

Japanese Paradise Flycatcher is the more common of the two paradise flycatchers in Shanghai. The photo above shows the differences in upperpart coloration between rufous-morph Amur Paradise Flycatcher and Japanese Paradise Flycatcher.

Fairy Pitta Pitta nympha

Fairy Pitta, Microforest 4, Cape Nanhui, Shanghai. 4 Sept. 2017. (Craig Brelsford)
Fairy Pitta, Microforest 4 (30.953225, 121.959083), Cape Nanhui, 4 Sept. 2017. The first week of September seems to be peak season for these passage migrants in Shanghai. The pitta shown here is a juvenile, discernible as such by the pinkish tip to its bill. The IUCN lists Fairy Pitta as Vulnerable. (Craig Brelsford)

On 4 Sept. at Nanhui, Elaine and I sneaked away from the action in Nanhui’s Microforest 1, where the photographers were set up. Microforest 4 was devoid of humans and peaceful. I tiptoed in. I scanned the undergrowth before me and, to my surprise, found a Fairy Pitta.

The pitta was standing on the ground, almost completely blanketed by a tangle of leaves, branches, and vines. Its big black eye was fixed on me. It didn’t move. I looked at the pitta, the pitta at me.

We stared at each other for 10 minutes.

Thus roosts the pitta during migration. It parks itself in thickets and waits. It bides its time, conserves its energy. Somewhere south of Shanghai, it will veer off the coast and fly non-stop across the South China Sea to Borneo, where it will spend the winter.

The pittas are mainly tropical species. Most are short-distance migrants. Not Fairy Pitta. No pitta invades the temperate world as deeply as Fairy Pitta; none makes so audacious an incursion into the north. None makes so long and daring a migration across hundreds of miles of sea.

My pitta was saving up its energy for its life-or-death run across the sea. Good luck, you explorer, you risk-taker! Good luck, Fairy Pitta.

Viewed with my wife Elaine Du at dusk 3 Sept. then viewed again the next morning at dawn. For weeks, the painted-snipes have been found at a single spot (30.939534, 121.955370) in a trash-strewn canal. Earlier, when news of the painted-snipe at Cape Nanhui first broke, I wrote a post in which I regretted sharing the location where were found the painted-snipes, a rare species in Shanghai. As things stand now, I can breathe easier; the many photographers who have visited the location have had no ill effect. The birds I found 4 Sept. were aware of me but behaved normally. They fed, drank, and preened. I used my car as a blind and never got out. The painted-snipes at Nanhui tolerate photographers confined to their cars.

Party of 3 on 26 Aug. at Cape Nanhui. When flushed, made loud, raspy, memorable call.

Dark underwing clear in my many photographs of the trio. Flew high when flushed, then returned to land at point only 50 m from where originally flushed.

The canals on the inland side of the sea wall were resounding with the characteristic yaps of this passage migrant. A clear photo is especially useful for discerning the thick bill.

Lesser Cuckoo Cuculus poliocephalus

Lesser Cuckoo, 26 Aug., Cape Nanhui. (Craig Brelsford)

Non-hepatic adult 26 Aug. at Cape Nanhui. See photo above. Reasoning behind ID of Lesser Cuckoo:

(1) No suggestion of brighter yellow iris that is characteristic of Eurasian Cuckoo as well as Oriental and Himalayan Cuckoo (darker iris more characteristic of Indian Cuckoo and Lesser Cuckoo)

(2) Dark rump and uppertail coverts contrast little with dark tail, while dark tail and rump contrast markedly with paler back, all pointing to Lesser Cuckoo

(3) On tail, very likely no subterminal black band (as in Indian Cuckoo), pointing again to Lesser Cuckoo

Cuculus sp., 4 Sept. 2017, Cape Nanhui. (Craig Brelsford)
This cuckoo, seen 4 Sept. 2017 at Cape Nanhui, has the dark eye, well-defined and widely spaced barring, and small size suggestive of Lesser Cuckoo. (Craig Brelsford)

Pale-legged Leaf Warbler
Phylloscopus tenellipes

Sakhalin Leaf Warbler

P. borealoides

In the wake of my post of 31 Aug. 2017 about distinguishing Pale-legged from Sakhalin Leaf Warbler by call, I was hoping to find more members of this species pair. On 4 Sept. 2017 at Pudong‘s Cape Nanhui, I was richly rewarded. For more, see my 10 Sept. 2017 post, “Pale-Sak Calls: An Addendum.”

Sand Martin Riparia riparia

Riparia riparia is an uncommon passage migrant in Shanghai. Note the well-defined breast band on my bird, distinguishing it from Pale Martin Riparia diluta, which has an ill-defined breast band.

Siberian Blue Robin Larvivora cyane

It’s worth stressing how good is our opportunity here in Shanghai to view Siberian Blue Robin for a few short weeks each spring and fall. On the breeding grounds up in northern China, the males sing loudly and beautifully but are very hard to see; no Siberian Blue Robin I experienced on the breeding grounds ever sang from anything like an exposed perch. The few I was able to see in Elaine’s hometown of Boli, Heilongjiang sang on or near the ground. Females are almost impossible to see; in fact, I saw not one in Heilongjiang in May-June 2016. Siberian Blue Robin are also apparently hard to see on their wintering grounds in south China and Southeast Asia. Places such as Cape Nanhui are probably among the best places in the world to view this common but shy species. We Shanghai birders have yet another reason to count ourselves lucky.
