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 round nostrils. 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.
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.

Rare
Under 5% of wildlife watchers report a Banded Bay Cuckoo sighting in Thrissur on a given day, based on 116 verified sightings from GBIF citizen-science data. It is the 130th most-seen of the 217 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
February, June and November–December
In those months about 10% of wildlife watchers report a Banded Bay Cuckoo in Thrissur on a given day, against under 5% in January, March–May and July–October, the lowest months.

GBIF citizen-science records
It is estimated from how often the Banded Bay Cuckoo is recorded against all the birds logged in Thrissur (116 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
