CUCKOO

Cuckoos are medium-sized birds that range in size from the Little Bronze Cuckoo, at 17 g and 15 cm (6 inches), to the Channel-billed Cuckoo, at 630 g (1.4 lbs) and 63 cm (25 inches). There is generally little sexual dimorphism in size, but where it exists, it can be either the male or the female that is larger.  Advertisement
