© Craig Brelsford (craigbrelsford.com, shanghaibirding.com). Lesser Cuckoo Cuculus poliocephalus, non-hepatic adult. 26 Aug. 2017. Cape Nanhui, Shanghai, China. Reasoning behind ID of Lesser Cuckoo: (1) No suggestion of brighter yellow iris that is characteristic of Eurasian Cuckoo as well as Oriental and Himalayan Cuckoo (darker iris more characteristic of Indian Cuckoo and Lesser Cuckoo) (2) Dark rump and uppertail coverts contrast little with dark tail, while dark tail and rump contrast markedly with paler back, all pointing to Lesser Cuckoo (3) On tail, very likely no subterminal black band (as in Indian Cuckoo), pointing again to Lesser Cuckoo
