Cuckoos of Shanghai

The Cuckoos of Shanghai: Craig Brelsford examines the Shanghai-area parasitic cuckoos and teaches you how to tell them apart. The non-Cuculus parasitic cuckoo that one is most likely to see in Shanghai is Large Hawk-Cuckoo. Rufous Hawk-Cuckoo, Asian Koel, and Chestnut-winged Cuckoo also are occasionally noted.

Indian Cuckoo, Common Cuckoo

Indian Cuckoo & Common Cuckoo: A Comparison: Note the smaller size of Indian Cuckoo, its thicker barring, and its darker iris. Voice as always is the surest differentiator. Both Indian Cuckoo and Common Cuckoo occur on passage in Shanghai and breed in the region.

Cuculus

Why This Cuckoo Is Lesser Cuckoo: The Cuculus I saw at Shanghai’s Cape Nanhui in September had the dark eye, well-defined and widely spaced barring, and small size suggestive of Lesser Cuckoo. See my photos of the thrush-sized cuckoo.

My Exchange with a Reader About Cuculus Cuckoos: “Draw a circle around the five [Cuculus] cuckoos [of China],” Craig Brelsford instructs a shanghaibirding.com reader. “Within that circle, draw three circles: one around Indian, one around Lesser, and one around Common, Himalayan, and Oriental.” Using this method, one quickly clusters the three main groups of Cuculus in China.
