“I have thought a lot about yesterday and can honestly say, it must be one of my all-time ornithological highlights.”
— Dr. Mike May, message to Craig Brelsford, 14 May 2017
Those are the words not of a new birder, but of a highly experienced visiting birder with thousands of birds on his life list who resides in bird-rich Extremadura, Spain.
Birding Pudong’s Cape Nanhui at the height of the spring migration left Mike May open-mouthed. Should anyone be surprised? The most southeasterly point of Shanghai is a world-class birding site.
Mike’s 92-species day, Sat. 13 May 2017, with Beijing-based Swedish birder Jan-Erik Nilsén and me included ultra-rarities such as Orange-headed Thrush as well as Pallas’s Grasshopper Warbler and Lanceolated Warbler. A pair of sub-adult Black-faced Spoonbill were getting by on the ever-shrinking pools at the beleaguered site.
These records brought the all-time list for Cape Nanhui to 288 species, according to eBird—making Cape Nanhui the second-hottest birding hot spot in China.
Let me say that again: Of the thousands of birding spots in this vast, mega-diverse nation, the cape 60 km southeast of People’s Square is second only to Baihualing in Yunnan in species noted.
Sound unbelievable? Let me say something even more unbelievable: Not only is this rich spot completely unprotected, with not even a square meter preserved in any legal way; but it is, to the contrary, being actively destroyed, even as I tap out these words.
The backdrop to the work of Mike, Jan-Erik, and me was fleets of bulldozers and backhoes, busy throughout the weekend. They clattered and clanged, and the pumps transferring water into the newly dug canals whirred and chugged.
The pace of transformation is faster than ever now.
“Nanhui is gone,” my partners and I said.
A major ecological area, a place combining ease of access to millions of residents of Earth’s largest city and a favorable position on Earth’s greatest migratory flyway, is being utterly transformed.
While the Cape Nanhui that I have long known falls, huge tracts of adjacent tidal mudflat are being reclaimed, adding dozens of square kilometers to the land area of Cape Nanhui. Birding there in theory could have a future. A Cape Nanhui Nature Reserve could be set up in the new area.
But even as the Cape Nanhui we know falls, no one, to my knowledge, has hastened to reassure conservationists that areas in the newly reclaimed land will be set aside for birds.
In the city-province of Shanghai, which is the size of the U.S. state of Delaware, a few places have indeed been set aside, among them Chongming Dongtan. But those reserves are small, on remote islands far from mainland Shanghai, and practically unreachable by the millions of middle-class Shanghainese who lack a car.
Cape Nanhui, by contrast, is easily reachable from the city. And it is the one place where masses of bird lovers can conveniently get a taste of the grand spectacle that is spring migration along the east coast of the Eurasian supercontinent.
That opportunity is being taken away, not only from the birders alive today, but also from the birders of the future.
THE THRILL OF NANHUI IN MAY
Our agony over the fate of Nanhui was tempered by the joy of birding. Orange-headed Thrush showed up Saturday at the Magic Parking Lot (30.884898, 121.968229). With the two vertical bars on its face, our specimen was either of race melli (breeds Guangdong, etc.) or courtoisi (Anhui).
On Sunday the Magic Parking Lot delivered singing Grey-crowned Warbler Seicercus tephrocephalus, and in Microforest 2 (30.926013, 121.970705) an appearance was made by Alström’s Warbler S. soror. Neither breeds in the region; both are very rare vagrants to Shanghai.
Iron Track (31.003613, 121.907883) gave us singing Yellow-breasted Bunting in full breeding finery and singing Pallas’s Grasshopper Warbler. I captured the latter’s song, rarely heard in Shanghai.

The Marshy Agricultural Land (30.850707, 121.863662) near Eiffel Tower was highly productive, yielding Lanceolated Warbler, Forest Wagtail, and Striated Heron.

A DISCUSSION ABOUT SEICERCUS
Shanghai Birding is the WeChat companion to this Web site. Our members include everyone from persons brand-new to birding to some of the most knowledgeable birders in China. We discuss everything from the most common species to the most arcane.
Here is an edited transcript of a recent conversation on Shanghai Birding about the Seicercus warblers at Cape Nanhui:
Paul Holt: Can you post your recording of yesterday’s [14 May 2017] Alström’s Warbler as well please, Craig?
Craig Brelsford: Will post after I get home. Meanwhile, have you assessed the recording I posted yesterday morning? Do you agree it’s Grey-crowned Warbler? Jonathan Martinez, I’d like your view, too!
Craig Brelsford had earlier posted these sound recordings:
Grey-crowned Warbler Seicercus tephrocephalus 1/3, 14 May 2017, Magic Parking Lot (30.884898, 121.968229), Nanhui (00:36; 3 MB)
Grey-crowned Warbler 2/3 (00:49; 3.6 MB)
Grey-crowned Warbler 3/3 (01:08; 4.3 MB)
PH: Yes, Grey-crowned Warbler!
PH: For what it’s worth, while there are probably 30+ records of “golden-spectacled warblers” from coastal Hebei, very, very few have been as well documented as Craig’s and team’s recent Grey-crowned. Many have been photographed but far fewer sound-recorded. Alström’s is so far the only one so far known to breed north of the Qinling Shan (it’s a scarce and very local breeder at two, possibly three, sites in Beijing). Personally I’ve never seen soror in coastal Hebei (nor am I aware of any being sound-recorded there), but I have noted (and sound-recorded) 2 Bianchi’s S. valentini and 1 Martens’s S. omeiensis in coastal Hebei. I understand that the only (?) three coastal Hebei birds that have been captured and had their DNA compared have all been omeiensis. We’re very, very far from ascertaining the true statuses of these Seicercus in our area, but you perhaps should/might see more in Shanghai and coastal Zhejiang. As many of you already know, there are some excellent sound recordings of these on Per’s site.
CB: Great analysis, Paul, and great that you point out the resources on Per’s site. Jan-Erik and I got good sound recordings of the purported soror yesterday, and Charles Wu and I got some good shots, among them images of the outer tail feathers, which definitely had some white in them.
CB: Grey-crowned Warbler appeared in the microforests almost exactly a year ago: https://www.shanghaibirding.com/2016/05/20/great-records/
PH: Excellent, Craig. As you know they’ve all got white in their outer tails. Alström’s (aka Plain-tailed) doesn’t have much …
CB: Right, Paul; thanks. The discussion yesterday was one of comparison and degree. How little must the white be in the tail, we were asking ourselves, for a Seicercus to “qualify” as Alström’s/Plain-tailed? Was the white in our photos a little or a lot? We ended up thinking a little, and that and the song we recorded led us to a determination of soror. I’ll post my photos and recordings as soon as I’m home.
PH: Personally, Craig, I find it very difficult to judge the amount and distribution of white on the tails of these Seicercus in the field and think that a good photo with the tail splayed would really be necessary. Even then, the differences are small and subtle. Tricky group!
Jonathan Martinez: Regarding the ID of these Seicercus, I have found that call is by far the easiest way to ID them. They all have a characteristic call. Some of them, like Alström’s or Bianchi’s, are usually quite vocal; others not as much. It requires much more experience or use of sonogram to ID them by song, but a few of them (Alström’s especially) include their call in their song, and some of them (Grey-crowned, Martens’s) include a trill in their song. Others do not (Alström, Bianchi’s). ID-ing them on plumage is, of course, a level up.
Here is the voice of the Alström’s Warbler that I recorded with my Olympus DM-650 pocket recorder:
Alström’s Warbler Seicercus soror 1/4, 14 May 2017, Microforest 2 (30.926013, 121.970705), Nanhui (00:50; 3.6 MB)
Alström’s Warbler 2/4 (00:08; 1.9 MB)
Alström’s Warbler 3/4 (01:08; 4.3 MB)
Alström’s Warbler 4/4 (00:41; 3.2 MB)
