Medium64 gWoodland

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.

Yellow-billed Cuckoo (Coccyzus americanus)

Yellow-billed Cuckoo

Coccyzus americanus

Medium64 gForest

Adults have a long tail, brown above and black-and-white below, and a black curved bill with yellow especially on the lower mandible. The head and upper parts are brown and the underparts are white. There is a yellow ring around the eye. It shows cinnamon on the wings in flight. Juveniles are similar, but the black on the undertail is replaced by gray. The adults show no sexual dimorphism, and thus the males and females can't be told apart by plumage. Measurements: Length: 10.2-11.8 in (26–30 cm) Weight: 1.9-2.3 oz (55–65 g) Wingspan: 15.0-16.9 in (38–43 cm)
