The mangrove cuckoo (Coccyzus minor) is a species of cuckoo that is native to the Neotropics. Adults have a long tail, brown above and black-and-white below, and a black curved bill with yellow on the lower mandible. The head and upper parts are brown. There is a yellow ring around the eye. This bird is best distinguished by its black facial mask and buffy underparts. Although the scientific name is minor (meaning "small"), this species is on average the largest of North America's three Coccyzus cuckoos. Adults measure 28–34 cm (11–13 in) in length, weigh 64–102 g (2.3–3.6 oz) and span 38–43 cm (15–17 in) across the wings.
