The Surge

Spring has surged into Shanghai! Elaine Du and I noted 92 species on the Qingming weekend. We found 212 endangered Great Knot at Nanhui and Bluethroat and Brown-headed Thrush on Chongming. Other highlights were 2 Greater Scaup and Black-necked Grebe on Chongming and at Nanhui 2 endangered Yellow-breasted Bunting, “Swintail” Snipe, 10 Saunders’s Gull (rare in Shanghai), 3 endangered Far Eastern Curlew, 2 Eurasian Bittern booming amid the sound of traffic, and 10 Pacific Swift.

Swintail
‘Swintail’ Snipe, Nanhui, 4 April 2016. Note the bill, shorter than the very long bill of Common Snipe, and the underwing, with ‘Swintail’ showing a uniformly dark, banded underwing and Common usually showing white underwing coverts. Note the pale, diffuse trailing edge to the wing of ‘Swintail,’ in contrast to the bright-white trailing edge of Common. ‘Swintail’ is birder’s jargon meaning Swinhoe’s Snipe or Pin-tailed Snipe, two species that are nearly impossible to separate in the field. The snipe pictured here could be either. (Craig Brelsford)

On Sun. 3 April 2016, fog once again kept Elaine and me off Hengsha Island, our original destination. Driving our rented Skoda Scout, we left the Hengsha ferry terminal on Changxing Island and took the Shanghai Changjiang Bridge across the Yangtze to Chongming Island. Visibility was less than 100 meters when we finally arrived at Chongming Dongtan National Bird Sanctuary and Nature Reserve. Rain, usually a drizzle, sometimes a shower, let up only briefly, around noon.

Swintail
This ‘Swintail’ was photographed 13 Sept. 2014 in Yangkou, Rudong, Jiangsu. Yes, sigh, it is nearly impossible to distinguish Swinhoe’s from Pin-tailed in the field. But it is possible, and much fun, to pick out ‘Swintail’ from Common! Note here the pale panels on the wings of ‘Swintail’ (visible in 1a, 2, and 3), note the lighter streaking on the back of this ‘Swintail’ than would be the case in a typical Common, and observe the lack of white trailing edge to the wings. (Craig Brelsford)

We stayed away from fee and permit areas. The northeast sea wall, with its well-protected mudflats beyond, is blocked off by guards wearing camouflage uniforms. A road running inside and parallel to the sea wall is not in a permit area and affords views of the canal-pond at the base of the wall. Reeds running along this inner road are the first tall, thick vegetation a bird flying along the coastline is likely to see and contained several migrants, among them the Brown-headed Thrush and a leaf warbler that may have been Chinese Leaf Warbler. The Phyllosc was soaking wet, and the characteristics I was noting, such as its seeming lack of a strong coronal stripe like Pallas’s Leaf Warbler, may have merely been the effect of the water. We noted the bright yellow rump, were starting to get hopeful–and then the bird disappeared.

On the eastern end of Chongming, we covered the farmland inside the sea wall and did not drive in the permit area atop the wall. We found the Bluethroat at the very good “snipe corner” (31.479537, 121.937001) south of Changjiang Lu. True to form, the skulker quickly hid away, refusing to flush or show. Still, the fleeting glimpse we got was Elaine’s best view ever of Bluethroat.

Common Snipe
Common Snipe, Chongming Island, Shanghai, 3 April 2016. Can you see the three main differences between this bird and the ‘Swintail’ above? To wit: longer bill, whiter underwings, and whiter trailing edge to the wings (visible, as here, even from below). (Craig Brelsford)

My walk through the reeds in pursuit of the Bluethroat scared up 2 Japanese Quail. Common Snipe were numerous, a pair of Oriental Skylark were hollowing out a tiny cup in the grass, and Water/Brown-cheeked Rail squealed once and fell silent. I recorded a fifth distinctive vocalization of Reed Parrotbill; I call this one the “siren.” (For the previous four calls, please visit “Amid the Din of the Diggers.”)

On Mon. 4 April, Shanghai-based British birder Michael Grunwell once again joined Elaine and me at Nanhui. We noted 73 species. Whereas outings in March gave us a “spring emerging from winter” impression, on Monday the transition to springtime felt complete. All that was missing were the flycatchers and the leaves on the trees in the microforests, those migrant traps dotting the sea wall.

Yellow-breasted Bunting
Yellow-breasted Bunting, Nanhui, 4 April 2016. Changes to wintering sites, loss of reed-bed habitat for roosting sites, and especially trapping for meat in southern China have reduced the population of this once-abundant species to a fraction of its former strength. (Craig Brelsford)

We rented no car, instead relying on the Shanghai Metro, taxis, a ride from a pair of friendly tourists, and our legs. With sunny skies and temperatures reaching 18 degrees, the weather was nearly perfect, and the exercise put us in a good mood.

The birding area at Nanhui is steadily going from “half-forgotten, mostly empty, natural” to “popular, busy, recreational.” Cars were packed around Nanhuizui Park and the Holiday Inn, and Qingming tourists were streaming out of the buses. Amid the commotion we found our first-of-season singing Manchurian/Japanese Bush Warbler as well as a single Asian House Martin flying among the swifts, the suddenly numerous Barn Swallow, and a single Red-rumped Swallow. At the Magic GPS Point (30.880540, 121.964572), we climbed to the deck of the derelict building next to the Holiday Inn. There, we enjoyed the expansive views, noted more Pacific Swift, and wondered how on earth a building as huge as this could be built and then immediately abandoned.

North of the Nanhuizui area, photographers were working on 12 Black-winged Stilt that were using a pond close to Microforest 2  (30.926039, 121.970725). Around that pond we found Marsh Sandpiper, Temminck’s Stint, and Sharp-tailed Sandpiper. The quiet, half-fallow fields behind the pond evoked memories of old Nanhui. We found our Yellow-breasted Bunting here as well as Chestnut-eared Bunting and about 60 of our 90 Pallas’s Reed Bunting. We were looking for but failed to find Japanese Reed Bunting. We noted the absence of harriers, which normally would be hovering over the fields and reed beds.

Great Knot were seen in flight and on the mudflats as the tide receded.

Oriental Skylark
Oriental Skylark, Chongming, 3 April 2016. This bird, one of the pair whose nest I saw being constructed, shows a pale-buff trailing edge to the wing, not the noticeably brighter white trailing edge characteristic of Eurasian. The tail is shorter than is typically the case in Eurasian. (Craig Brelsford)

  1. Loving your posts. As a new resident of Shanghai I am also discovering many of the places you write about albeit with a little less personal expertise, transport and time.
    I’m picking up 1 or 2 new birds each trip (world list 3677) still. I had 2 Marshall Grasbbirds inside Chongming Dongtan on the 2nd.
    Love to meet up this Spring for a jaunt perhaps.
