About the Dusky Long-tailed Cuckoo

The dusky long-tailed cuckoo (Cercococcyx mechowi) is a species of cuckoo in the family Cuculidae. It is found in forests in Central Africa. The IUCN has assessed it as a least-concern species.

The wings are dark brown, with buff and white spots. The underparts are white, with blackish-brown bars, and the vent is buff. The tail is long and graduated. The eyes are dark brown, the beak is greenish-black and the feet are yellow. The male and female are alike. The juvenile bird has a blackish throat and rufous bars on its upperparts.
