Chocolate-backed Kingfisher

The chocolate-backed kingfisher (Halcyon badia) is a species of kingfisher in the subfamily Halcyoninae, native to the African tropical rainforest. == Description == The chocolate-backed kingfisher has the typical stocky kingfisher shape with dark upper parts and pure white underparts. The head and hind neck are very dark brown, the mantle is brownish black, the back is black, the rump a brilliant iridescent blue, the upper tail coverts are black, and the tail is pale blue. The wings are dark, apart from a brilliant azure speculum formed in the outer webs of the secondary feathers. The underparts from the throat to the vent are snowy white, apart from a small blackish flank patch, and are clearly demarcated from the dark upper parts. In flight the brilliant blue rump and speculum are distinctive. The bill is red or reddish brown. Juveniles are similar to adults, except that the breast is scalloped and the bill is blackish with an orange tip. == Voice == A harsh screeching alarm note is given. The song is a high pitched, barely audible introductory "pee" followed by 12-17 long flutelike pure tones which are evenly spaced and far carrying, lasting 5–7 seconds, and sometimes falling away…
