Banded bay cuckoo
The banded bay cuckoo or bay-banded cuckoo (''Cacomantis sonneratii'') is a species of small cuckoo found in the Indian subcontinent and Southeast Asia. Like others in the genus they have a round nostril. They are usually founded in well wooded areas mainly in the lower hills. Males sing from exposed branches during the breeding season, which can vary with region. They are distinctive both in their calls as well as plumage with a white eyebrowed appearance and the rufous upperparts with regular dark bands and the whitish underside with fine striations.
==Description==
The adults are bright rufous or bay on the head and back and are broadly barred with dark brown. The bill is long and slightly curved. A whitish supercilium is distinctive above a dark eye-line. The wing is darker and tail is graduated with a dark brown centre. The tail has a subterminal black band and white tips to the feathers. The sexes are alike. The iris is yellow and the bill is black while the base of the lower mandible is greenish grey. The tarsi are grey. The juvenile is similar but has a pale lower mandible and white fringes to the feathers of the upper body.〔
The overall length is about 22 cm making it about the same size as the syntopic ''Cacomantis merulinus'' and ''Cacomantis variolosus''. The hepatic forms of those can be similar but supercilium, long beak and barred tail distinguish this species.
