A male Asian koel on the peepal tree outside my balcony.
Ref Wiki: The Asian koel is a large, long-tailed, cuckoo. It is a brood parasite that lays its eggs in the nests of crows and other hosts, who raise its young. They are unusual among the cuckoos in being largely frugivorous as adults. The male is glossy bluish-black, with a pale greenish grey bill, the iris is crimson, and it has grey legs and feet.
