Cape Nanhui is the coastal area at the southeastern tip of Shanghai. The site in Pudong, 85 km (53 mi.) from People’s Square, is the premier birding spot in Shanghai and one of the best-known birding areas in China. The microforests, a series of small woods, at Cape Nanhui are astonishingly effective traps for migrants such as Japanese Paradise Flycatcher and Siberian Blue Robin. The wetlands offer East Asian rarities Black-faced Spoonbill and Asian Dowitcher.
A major attraction is the eight microforests along the 10 km (6 mi.) stretch running north along the coastal road from the Magic Parking Lot (30.884992, 121.968317). Shown above is Microforest 4, the largest of the eight tiny woods at Cape Nanhui and an astonishingly effective migrant trap. During migration season, dozens of species of bird rely on these tiny woods.
Of the many families represented in the microforests, Muscicapidae stands out. Among the species commonly appearing are Mugimaki Flycatcher (above), Yellow-rumped Flycatcher, Dark-sided Flycatcher, Asian Brown Flycatcher, Grey-streaked Flycatcher, Blue-and-white Flycatcher, Taiga Flycatcher, and White-throated Rock Thrush. Daurian Redstart and Red-flanked Bluetail arrive every September and October and spend the winter.
PONDS & MUDDY AREAS
The ponds and muddy areas at Cape Nanhui offer a wide selection of birds. Oriental Pratincole breed in the area and at certain times of the year mass in the hundreds. During migration season, a birder’s Nanhui wader list may include Black-tailed Godwit, Red Knot, Broad-billed Sandpiper, Sharp-tailed Sandpiper, Curlew Sandpiper, and Long-toed Stint. Among the more numerous ducks are Eastern Spot-billed Duck and Eurasian Teal. Less numerous ducks include Eurasian Wigeon, Northern Shoveler, Northern Pintail, and Mallard. Lucky birders sometimes find Smew. Great Egret, Intermediate Egret, and Purple Heron all show up on Nanhui birders’ lists. Western Osprey fish in the ponds.
SCRUB & FIELDS
The scrub and fields of Cape Nanhui offer a unique set of birds. At large, open areas one can see Japanese Quail, Eastern Marsh Harrier, Hen Harrier (above), migrating Eurasian Wryneck and Oriental Dollarbird, Peregrine Falcon, Richard’s Pipit, Buff-bellied Pipit, Red-throated Pipit, and Chestnut-eared Bunting. Birders can view three subspecies of White Wagtail (leucopsis, lugens, ocularis) and all three subspecies of Eastern Yellow Wagtail (tschutschensis, taivana, macronyx [rare]).
Take one of several roads leading into the reed beds. My favorite road is at 30.912908, 121.972735. There you can find booming Eurasian Bittern, Yellow Bittern, breeding Oriental Reed Warbler and the Common Cuckoo that parasitize their nests, Chinese Penduline Tit, Black-browed Reed Warbler (above), and if you are very lucky migrating Middendorf’s Grasshopper Warbler and Japanese Reed Bunting. Marsh Grassbird, Manchurian Bush Warbler, and Brown-flanked Bush Warbler sing in spring, and Pallas’s Reed Bunting spend the winter.
This circular pond is worth checking in winter. Falcated Duck gather here in their hundreds, Tufted Duck and Greater Scaup flock together, and among the many Little Grebe one can make out a few Black-necked Grebe. Swan Goose (above) and Horned Grebe have been recorded here.
You can drive or take public transport to Cape Nanhui.
Driving: In Pudong, take the S2 south to the exit called Lianggang Dadao (两港大道). Set your navigation software to the Magic GPS Point and begin birding there.
Metro: Take Line 16 to the terminus at Dishui Lake (Dīshuǐ Hú [滴水湖]). Some birders take a taxi to the most distant microforests and from there walk nearly 10 km to the bus stop at the Holiday Inn near the Magic Parking Lot. From there, they take the bus back to Dishui Lake. It’s also possible to take the bus from the terminus to the Holiday Inn, but note that because the only bus stop in the area is at the Holiday Inn, a birder choosing this option would have to double back to the point of origin.

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 scarce vagrant to the Shanghai coast. Cyornis brunneatus breeds in southeast China, including interior Shanghai and the Tianmu Mountains, and spends the winter in peninsular Malaysia, Sumatra, and Borneo.
The IUCN lists the species as Vulnerable because of the loss of mature primary lowland forest throughout its range.
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., 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:
Amur Paradise Flycatcher Terpsiphone incei
Japanese Paradise Flycatcher T. atrocaudata
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.
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 PittaPitta nympha
On 4 Sept. at Nanhui, my wife, Elaine Du, 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.
Greater Painted-snipe Rostratula benghalensis
Viewed with Elaine 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.
Asian Dowitcher Limnodromus semipalmatus
27 Aug., South Pond. Juvenile. Videoed by me using my iPhone 6, adapter by the U.S. company PhoneSkope, and my Swarovski ATX-95 spotting scope:
Chinese EgretEgretta eulophotes

Black BitternIxobrychus flavicollis
Uncommon in Shanghai. Found 26 Aug. at Cape Nanhui.
Striated HeronButorides striata
Uncommon in Shanghai. Found 27 Aug. at Binhai Forest Park.
Adult plus another goshawk calling unseen at inner-city Zhongshan Park on 8 Sept.
I videoed the goshawks:
Pacific Golden PloverPluvialis fulva Grey-headed LapwingVanellus cinereus
27 Aug. at sod farm south of Pudong Airport.
Great KnotCalidris tenuirostris
In high-tide roost 4 Sept. on South Beach (30.860673, 121.925113), just north of Donghai Bridge at Cape Nanhui.
Curlew SandpiperC. ferruginea
South Pond, Cape Nanhui, 26 Aug. Video:
Pin-tailed SnipeGallinago stenura
Party of 3 on 26 Aug. at Cape Nanhui. When flushed, made loud, raspy, memorable call. I quickly compared the call I had just heard to calls of Pin-tailed Snipe downloaded from xeno-canto.org to my iPhone. The match was perfect. Lookalike Swinhoe’s Snipe rarely calls when flushed. 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.
Gull-billed TernGelochelidon nilotica
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.
Pale-legged Leaf Warbler Phylloscopus tenellipes
Sakhalin Leaf Warbler P. borealoides
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 RobinLarvivora 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.

In the wake of my recent post on distinguishing Pale-legged Leaf Warbler from Sakhalin Leaf Warbler by call, I have been hoping to find more members of this species pair in Shanghai. On 4 Sept. 2017 at Pudong’s Cape Nanhui, my hopes were fulfilled in a big way. At the Magic Parking Lot (30.884889, 121.968222), not one but both species were calling.
Below, the recordings I made with my Olympus DM-650 pocket recorder. The first Sakhalin recording was made at Microforest 4 (30.953225, 121.959083), 7.7 km north of the Magic Parking Lot on the coastal road. The others were made at the Magic Parking Lot.
Note the higher frequency of the calls of Pale-legged—on average a full kilohertz higher. The difference is discernible by the keen listener, but nothing tells the story better than the spectrograms.
To summarize what I argued in the previous post: The calls, as well as the very distinctive songs, of Pale-legged Leaf Warbler and Sakhalin Leaf Warbler are diagnostic—that is, they differ markedly and consistently and are a reliable basis for an ID. The diagnosability of the calls of the two species has been affirmed by various researchers, among them Yap et al. (2014; Birding Asia 21: 76–81).
Featured image: Pale-legged/Sakhalin Leaf Warbler, Jiangsu, May. Some of the salient characteristics of Pale-Sak are pointed out. Separating Pale-legged from Sakhalin on the basis of plumage and bare parts is not possible; because this bird was neither singing nor calling, it cannot be determined to which of the two species it belongs. (Craig Brelsford)
Editor’s note: In the photo above, a Pale-legged Leaf Warbler emits its characteristic “tink” call in Microforest 4, Cape Nanhui, Pudong, 27 Aug. 2017. The tink call of Pale-legged is appreciably higher-pitched than that of Sakhalin Leaf Warbler. Distinguishing the two calls is the subject of this post. — Craig Brelsford
Last September, in “Pale-legged Leaf Warbler & the Shanghai Big 5,” I asserted that “Pale-legged Leaf Warbler is safely separable from Sakhalin Leaf Warbler only by song.” I was wrong. Call as well as song is a reliable separator. In this post, I am going to tell you how I arrived at this insight, and I will show you how you too can achieve clear, indisputable ticks of these tricky species through call alone.
Experts since at least as far back as 1989 have been arguing that Pale-legged Leaf WarblerPhylloscopus tenellipes and Sakhalin Leaf WarblerP. borealoides are separable not only by their distinctive songs but also by their calls. Thailand-based birder and shanghaibirding.com contributor Phil Round is among those making that argument. Round and his co-authors write: “[T]he call of P. tenellipes is markedly higher in frequency than that of P. borealoides” (Round et al., “Addition of Kamchatka Leaf Warbler Phylloscopus examinandus and Sakhalin Leaf Warbler P. borealoides to Thailand’s Avifauna,” downloadable through shanghaibirding.com).
If your ear is good, or even if your ear is just average and you have a sound-recorder, then you too can appreciate the higher frequency of the call of Pale-legged. A sound-recorder is important, because if you upload your recordings to databases such as eBird and the Macaulay Library, then you will be able to “see” the sound in the audio spectrogram.
Our first exhibit is the spectrogram of a call I sound-recorded of Sakhalin Leaf Warbler on 8 May 2016 in Cape Nanhui’s Microforest 4 (30.953225, 121.959083). The frequency is 4.8 kilohertz, a number that matches closely the frequency of Sakhalin calls on xeno-canto.org.
Now consider the spectrograms and sound-recordings of Pale-legged Leaf Warbler below. The spectrogram immediately below was recorded by me on 10 June 2016 in my wife Elaine Du’s hometown of Boli, Heilongjiang, part of the breeding range of Pale-legged Leaf Warbler. The call (here a grace note) and song both clock in at about 6 kHz, a frequency a full 25 percent higher than the call of Sakhalin Leaf Warbler and, as with Sakhalin, consistent with the frequencies of Pale-legged calls on xeno-canto.org.
Here is the sound-recording:
Pale-legged Leaf Warbler, call and song, Xidaquan National Forest (45.727751, 130.317316), Boli, Heilongjiang, 10 June 2016 (01:59; 6 MB)
The spectrogram below is of a brief sound-recording I made in Microforest 4 this past Sunday. The song element of this passage migrant is absent (though note that I have heard Pale-legged and Sakhalin singing in Shanghai in spring). The call has a frequency of 5.9 kHz and clearly belongs to Pale-legged Leaf Warbler.
Why should you care about all this? Because prepared birders have a chance to get solid ticks of “Pale-Saks” that are merely calling and not necessarily singing. If you hear a Pale-Sak calling and trust your ear (or better yet, sound-record the call and later analyze the spectrogram), then you may be able to go beyond the safe, boring record of “Pale-legged/Sakhalin Leaf Warbler” to a more satisfying full tick.
Accurate, plentiful records from Shanghai will help researchers such as Round get a clearer picture of the movements and population of these understudied species. As Round et al. write: “Increased sampling of migrants may also resolve the differences in timing of passage between P. examinandus and P. borealis on the one hand, and P. borealoides and P. tenellipes on the other” (“Addition”; hyperlink mine).
What’s more, you do not need to spend much or even know much to record good audio. My Olympus DM-650 costs less than US$250. I have no microphone other than the one built into my pocket recorder, and I possess no parabola. I record in lossless 48kHz .wav. The very scientific-looking spectrograms displayed in this post are generated automatically by eBird and Macaulay.
In Shanghai and throughout China, important facts about common birds such as Pale-legged Leaf Warbler and Sakhalin Leaf Warbler remain unknown. This ornithological semi-wilderness is both difficult and exciting. If we rise to the challenge and become better birders, then we will make new discoveries and blaze a trail of knowledge for future birders to follow.
