Far Eastern CurlewNumenius madagascariensis, Liaoning, China, September. (Craig Brelsford)
Far Eastern Curlew and Eurasian Curlew are most easily separated in flight. Then one can see the barred brown underwing of Far Eastern (1) as well as its entirely brown upperparts (3). The underwing coverts and axillaries of Eurasian Curlew (ssp. orientalis) are, by contrast, mainly white (2). The back and rump are also white (4). 1 and 3: Jiangsu, China, September. 2 and 4: Jiangsu, October. (Craig Brelsford)
On Tuesday I arrived at Cape Nanhui too late to see Crow-billed Drongo. My partners Kai Pflug and Elaine Du and I made the fateful decision to cover Hengsha Island in the morning. The alluvial island at the mouth of the Yangtze was decidedly humdrum, with Far Eastern Curlew out on the mud along with 2 Sanderling and a Ruddy Turnstone. The huge new tree plantation on the island failed to deliver any forest birds beyond a single Asian Brown Flycatcher. There was a good count (17) of Richard’s Pipit.
We arrived at Cape Nanhui and found kaca, who mentioned an unusual drongo he had seen that morning. We kept our eyes peeled for dark drongos, finding none. Our Nanhui harvest was limited to expected October birds such as Grey-backed Thrush (6) and Eyebrowed Thrush (2). Asian Brown Flycatcher (26) seemed to be on every tree.
All of Shanghai’s Big 5 Leaf Warblers were present: Pallas’s Leaf Warbler (1), Yellow-browed Warbler (1), Arctic-type Warbler (2), Pale-legged/Sakhalin Leaf Warbler (7), and Eastern Crowned Warbler (2).
