Gray-headed Fruit-Dove

Large trogon, shimmering emerald above with red belly. Male has noticeable golden sheen on head and yellow bill; female has brown head and duller brownish chest and bill. In all plumages, look for entirely dark tail and dark eye to help separate from similar Crested Quetzal. Found in forests and edges in the subtropical zones. Tends to perch stolidly in the subcanopy; can be difficult to spot. Most often seen in the vicinity of a fruiting tree, singly or in pairs, although sometimes several birds can gather at a food source. Listen for mournful song, a repeated “go home, go home, go home.”

One of the smallest owls in the world, about the size of a sparrow. Patterned with rufous, gray, and white. Most similar in plumage to Flammulated Owl, but note the Elf Owl's white eyebrows, yellow eyes, tiny size, and habitat. Found in brushy woodlands and surrounding desert, where they nest in natural cavities or abandoned woodpecker holes in trees and cacti. Nocturnal; most easily found by listening for call around dusk: a descending whiny chuckle or single mewing note. Migrates south to Mexico for the winter.

Small, richly colored owl with small ear tufts. There are two morphs: one rich rufous and the other pale gray-brown. Found in lowland rainforest on the island of Principe. The vocalization is a series of hollow “klow” notes, similar to those of African Scops-Owl, but delivered much more quickly, about one note / second. Easily identified, as the only other owl on Principe is the much larger Barn Owl.
