Curlew SandpiperCalidris ferruginea breeds in high-Arctic Siberia. Uncommon migrant across all China; some birds overwinter in Hainan, Guangdong, and Guangxi; also Taiwan. HABITAT & BEHAVIOR Migrants usually seen roosting and feeding with other calidrids. Frequents coastal mudflats, less often marshy areas inland. Probes mud vigorously; ventures into deeper water than DunlinC. alpina. ID & COMPARISON Like Red KnotC. canutus, has striking red breeding plumage, but more chestnut-red compared to more orange-red in Red Knot. Red Knot is larger and bulkier, with much shorter tibia. In all plumages, Curlew Sandpiper has narrow white wing bar and distinctive white rump (visible in flight), but rump of Red Knot is barred grey. Breeding adult has most of head, neck, and underparts rich rufous, but note whitish area around base of bill. Crown streaked; vent and undertail coverts white with sparse dark chevrons. Feathers on mantle and scapulars alternatively black and chestnut with whitish feather tips, giving mottled appearance. Winter mostly grey above, white below, with white supercilium and dark eye-line. (Winter Dunlin has less distinct white supercilium and shorter neck, legs, and wings.) Juveniles scaly above with grey feather centers; neck and breast buffy and streaked; distinct whitish supercilium; underparts pure white. BARE PARTS Bill long, black, and decurved throughout length; bill of Dunlin droops mostly at end, bill of Red Knot short and straight. Smaller Broad-billed SandpiperC. falcinellus similar to Curlew Sandpiper in winter plumage but has shorter neck and legs and straighter bill, drooping strongly at tip. Feet and long legs black (longer than Dunlin); legs and feet of Red Knot greenish-yellow or blackish. VOICE Trilling “chirrup” call noticeably softer and deeper than raspy call of Dunlin; somewhat like call of Red-necked StintC. ruficollis. — Craig Brelsford
On Sat. 5 Aug., I resumed birding at Pudong’s Cape Nanhui after a two-month hiatus. Battling apparent temperatures of 42 degrees Celsius (108 degrees Fahrenheit), partner Ian Reid (above) and I noted 74 species. The haul was good, but even better was the insight it afforded me. Once again, I learned that when it comes to birding, the most southeasterly point of Earth’s Greatest City delivers month after month, season after season.
Ian and I had 3 juvenile Asian Dowitcher, the most notable among an all-star team of shorebirds that included 8 Black-tailed Godwit, Ruff, 12 Broad-billed Sandpiper, and 3 Curlew Sandpiper still mainly in brick-red breeding plumage. A Red-necked Phalarope was making use of fallow rice paddies, and 6 Grey-tailed Tattler were on the mudflats near Donghai Bridge. We had unusual Nanhui records of Pied Kingfisher and Ruddy Shelduck.
The microforests were quiet, but a very early record of Eastern Crowned Warbler and Yellow-rumped Flycatcher offered a preview of the passerine party coming in September. We had four species of bittern: Eurasian Bittern, Yellow Bittern, Cinnamon Bittern, and Black Bittern.
In my nearly 10 years in Shanghai, I had never birded Cape Nanhui in the first week of August. During Shanghai’s hottest month of the year, I am almost always birding in cooler climes—in Qinghai last year, for example, and in 2015 in my wife Elaine’s hometown in Heilongjiang.
Ian’s and my day both reminded me of the good reasons for vacating Shanghai this time of year and showed me the treasures I have been missing. Through the oppressive heat, which ensured that you would never stop sweating, and the 81-percent humidity, which ensured that the perspiration wouldn’t do much good, the Australian birder and I steadily built up an impressive list.
Our trio were juveniles, with their dark-brown crowns and buff-fringed, dark-brown upperparts. They were feeding together at South Pond (30.873934, 121.953180). The tide had hit the nearby sea wall and driven in small numbers of shorebirds of various species, among them Sharp-tailed SandpiperCalidris acuminata, Curlew SandpiperC. ferruginea, Long-toed StintC. subminuta, and Broad-billed SandpiperC. falcinellus.
An East Asian specialty, Asian Dowitcher breeds in a disjointed set of ranges from western Siberia to Heilongjiang. The IUCN lists it as Near Threatened.
Eastern Crowned WarblerPhylloscopus coronatus
We found a single individual in the Cathedral of Birding, the broad, spacious northern end of Microforest 4 (30.953225, 121.959083). This is a very early record of a species that, like so many other passerines on passage through the Shanghai region, does not begin to show up in impressive numbers until September. As with the dowitchers, when I saw this warbler, my initial reaction was, “What else have you been missing over the years for failing to bird Nanhui in early August?”
Nearby we had female Yellow-rumped FlycatcherFicedula zanthopygia, a less surprising record, as the species breeds in Jiangsu.
Ruddy ShelduckTadorna ferruginea
Ruddy Shelduck in August is yet another unexpected record. We found a single individual associating with domestic waterfowl near the entrance to the defunct wetland reserve (30.920507, 121.973159). The species is uncommon in Shanghai at any time of year, with most records coming in winter.
Pied KingfisherCeryle rudis
Perhaps the most surprising aspect of this record is that it is surprising at all. Pied Kingfisher breeds throughout southern China, yet this record was my first of the species in Shanghai. A pair has been present at Cape Nanhui since at least July.
Eurasian BitternBotaurus stellaris
Our first of the four species of bittern. We found 2.
Yellow BitternIxobrychus sinensis
We found 24 of this local breeder along the length of the 30-km coastal road.
Cinnamon BitternIxobrychus cinnamomeus
Found in habitats similar to Yellow Bittern, but in much smaller numbers (4).
Black BitternIxobrychus flavicollis
One was seen flying just north of Eiffel Tower (30.850531, 121.878047). This species has an affinity for swamps in forests and is uncommon in Shanghai. Saturday’s record was only my second in the city.
Common KestrelFalco tinnunculus
A species common in Shanghai, noted here only because of the circumstances under which Ian and I found it. The first impression of “juvenile falcon” that I received came not from the plumage but from the blunders of the kestrel. The falcon got too close to some juvenile Black-winged Stilt–and found itself being chased off by an adult, a giant in comparison. This was clearly a rookie’s error and betrayed the inexperience of the attacker.
In the photo above, note the lightly streaked ear coverts, the lack of scythe-like wings (as in Eurasian Hobby), black remiges, and long tail with rounded tip. The strong black streaking on the underparts will grow thinner as the kestrel matures.
Peregrine FalconFalco peregrinus
A welcome addition to any Nanhui list, Falco peregrinus is usually recorded in Shanghai in autumn and winter. Sharp-eyed Ian spotted the falcon roosting in an area that used to contain reed beds but has since been flattened by the backhoes into a savanna-like landscape. I got video on my iPhone through the spotting scope.

On Sat. 8 April I birded Cape Nanhui with John MacKinnon. John is co-author of A Field Guide to the Birds of China, the most influential book ever written about China’s birds. On John’s first visit to the tip of the Shanghai Peninsula, we noted 84 species. John and I were joined by veteran birders Michael Grunwell and Russell Boyman and the outstanding high-school birder Larry Chen.
We gave John the Grand Nanhui Tour, starting at Luchao to the south and ending 30 km north at Binhai. Heading back to the city, we made a brief stop at the sod farm just south of Pudong Airport, where we found a single Oriental Plover.
Nanhui yielded 23 Marsh Grassbird performing the song flight at three locations, and we saw 10 Endangered Great Knot and 1 Near Threatened Curlew Sandpiper. We had a pair of Rufous-faced Warbler and a Common Starling.
Also: Garganey 57, Greater Scaup 1 (Dishui Lake), Little Curlew 31 (flock), Sharp-tailed Sandpiper 11 (first of season), Red-necked Stint 1 (first of season), Wood Sandpiper 1 (first of season), Peregrine Falcon 1, Dusky Warbler 1 at Magic Parking Lot (possibly wintered there), and Reed Parrotbill 18.
John is witty and a fine storyteller. He had us roaring with tales drawn from his six decades as a researcher in Asia. The funniest story was about the doctor back home in Britain. Every time John straggled in, the doc would call in his students, so that they could study the strange new tropical disease John had contracted.
“I never cared about my health, because I never expected to live this long!” John said.
John also talked about his masterpiece, A Field Guide to the Birds of China.
It is difficult to overestimate the importance of the Field Guide. Had it merely been a window for Westerners to the birds of the world’s most populous country, then John’s work would have been important enough. The Field Guide, however, in translated form has introduced tens of thousands of Chinese to the birds of their own country. John’s Chinese name, Mǎjìngnéng (马敬能), is known by every birder in China.
John faced obstacles unknown to field-guide writers in North America and Western Europe, where birding has been practiced for 200 years. His sources were often thin, he said.
“For range maps, I had nearly nothing from Russia,” John said. “A Chinese book had ranges stopping at the Chinese border. Another book had no paintings, only descriptions.”
To critics who unfairly compare John’s Field Guide to field guides covering more developed parts of the world, John had this to say:
“You’ve got to finish something. We finished the book. We could have waited and said, ‘Oh, another species has been split, we must revise,’ but at a certain point you have to say, ‘We must go with what we’ve got.’”
To this day, no Westerner has repeated John’s feat. Others talked; John acted.
John is a handy photographer and got off some good shots, three of which are displayed in the Day List at the bottom of this post. Here are some photos I took of the pioneer birder and naturalist.
MARSH GRASSBIRD ON THE BRINK
Marsh Grassbird were singing in the large reed beds at Nanhui. They were most conspicuous at the reed bed south of the Holiday Inn (30.870711, 121.942976). The species, listed as Near Threatened by IUCN, was also noted in the pristine reed bed (30.931790, 121.949169) associated with the defunct wetland reserve.
The reed beds at Cape Nanhui may be the last stronghold of Helopsaltes pryeri sinensis on the Shanghai Peninsula. The species is highly dependent on large reed beds. In areas where only strips of reeds remain, the song of Marsh Grassbird is never heard. Its partner species, Reed Parrotbill, a candidate for official bird of the city-province of Shanghai, is only slightly less dependent on large reed beds.
One of the areas where last year my partners and I noted Marsh Grassbird performing its song flight has been flattened. No song of Marsh Grassbird was heard there Saturday. A few Reed Parrotbill were calling in one of the strips of reeds left standing.
Much needs to be learned about Marsh Grassbird in Earth’s largest city. Birders, look for the fluttering song flight, and listen for this song:
