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.
— 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.
Editor’s note: Hangzhou Botanical Gardens and the Tianmu Mountains are must-see destinations for Shanghai birders, especially those of us new to birding in southeast China. Hangzhou Botanical combines ease of access (it can be visited in a day on the bullet train) with the chance to see southeast China birds whose ranges do not reach Shanghai. Visiting the Tianmu Mountains or Tianmushan is more of a project than visiting Hangzhou Botanical, but the rewards are greater. No place so close to Shanghai offers as much high-quality mountain forest as Tianmu.
In this guest post, Shanghai birder Larry Chen tells us about his recent trip to Hangzhou Botanical and Tianmu. As Larry makes clear, a trip to those locations, even at the height of summer, is worth the Shanghai birder’s time.
If Larry’s report whets your appetite and you want to know more, then take a look at these resources:
Komatsu Yasuhiko, Zeng Qiongyu, and I covered Tianmushan 6-8 July 2017. We hiked up to around 1500 meters above sea level and explored some beautiful top-quality mixed forest, including stands of the magnificent Japanese Cedar Cryptomeria japonica and Huangshan Pine Pinus hwangshanensis, as well as roadside mixed deciduous, conifer, and bamboo forest.
Some of the avian highlights from our three-day trip were the diminutive and bamboo-loving Short-tailed ParrotbillNeosuthora davidiana, Moustached LaughingthrushGarrulax cineraceus, and the regal Black EagleIctinaetus malaiensis.
The weather at Tianmu, unlike hot and humid Shanghai, was humid but relatively cool, and plenty of shade was provided by the extensive foliage.
Hiko and I visited Hangzhou Botanical on 5 July, managing to find, despite the heat, several species whose ranges do not quite reach Shanghai, among them Asian Barred OwletGlaucidium cuculoides, Grey TreepieDendrocitta formosae, and Red-billed Blue MagpieUrocissa erythroryncha.
I recommend Tianmu and Hangzhou Botanical to anyone seeking a few days’ trip out of Shanghai. Tianmushan has some beautiful habitat, comfortable but cheap accommodations, and a truly under-watched avian diversity.
We had 65 species at Hangzhou Botanical and Tianmu. Highlights:
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-CuckooHierococcyx 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.
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-CuckooHierococcyx 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.
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.
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
The other non-Cuculus parasitic cuckoos of the Shanghai region are Asian KoelEudynamys scolopaceus and Chestnut-winged CuckooClamator coromandus. Neither poses 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.
Five Cuculus cuckoos have been claimed for Shanghai: Lesser CuckooCuculus poliocephalus, Indian CuckooC. micropterus, Himalayan CuckooC. saturatus, Oriental CuckooC. optatus, and Common CuckooC. 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.
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.
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.
Lesser CoucalCentropus 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 CoucalCentropus 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.
RESOURCES ON CUCKOOS
The Sounds of Shanghai’s Cuckoos, by Craig Brelsford
All cuckoos from the Shanghai area are covered here. I make my recordings with my handy little Olympus DM-650.
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.

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).
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 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.”
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?
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.
Michael, Hiko, and I noted 64 species on Sun. 26 March 2017. Besides the plovers, we had 10 Marsh Grassbird singing from deep cover, Common Reed Bunting feeding alone on the ground, and 4 Bar-tailed Godwit, 1 of which had been banded on Chongming Island.
Also Garganey 59, Eurasian Teal 625, Eurasian Bittern 8 booming, Hen Harrier 1 male, Pied Harrier 1 female, Eurasian Curlew 2, Great Knot 2, Ruff 6, Sanderling 1, Dunlin 350, and Japanese/Manchurian Bush Warbler 3 singing.
At Nanhui, we had skittish Short-eared Owl and breeding Black-necked Grebe (Dishui Lake). We found no Hooded Crane, our well-known individual most likely having departed after its historic winter sojourn on the tip of the Shanghai Peninsula.
COLLECTING RECORDS ON WECHAT
