Large Hawk-Cuckoo

The large hawk-cuckoo is a cuckoo with a wide breeding distribution from temperate Asia along the Himalayas to East Asia, and many populations winter further south. It is a brood parasite of babblers and laughingthrushes, and its eggs mimic those of its hosts. Adults are somewhat larger than the common hawk-cuckoo and can be told from it by a black patch on the chin (Wikipedia, general species account).

It is known for loud, repetitive calls that are like those of the common hawk-cuckoo but do not rise in a crescendo, given in summer and often well after dusk. Many laughingthrushes can detect and remove cuckoo eggs.
