Plump ground-dwelling dove, quite bright and colorful compared with other quail-doves. Body is grayish, wings are rich brownish-purple, and nape is suffused with iridescent green. Like many quail-doves, face is whiter with dark mustache line, but note buffy forehead. Pinkish-red legs. Sexes alike. Prefers forests, usually on the ground unless flushed up into the lower levels of a tree. Like most quail-doves, often best seen by quietly walking along trails at dawn and dusk.

The buff-fronted quail-dove is a year round resident from northern Costa Rica's Cordillera de Guanacaste southeast into western Panama as far as Veraguas Province.

行为
The buff-fronted quail-dove forages alone or in pairs, searching leaf litter on the forest floor. Its diet is not well known but includes fruit, seeds, and probably insects.<p>Little is known about the buff-fronted quail-dove's breeding phenology. The one described nest was a nearly flat platform made of coarse twigs, moss, and liverworts. It was almost 4 m (13 ft) above the ground on a horizontal branch of a tall shrub and contained one nestling.<p>The buff-fronted quail-dove's song is "a low, hollow hoOOOO", louder towards the end and with a slightly rising inflection".

Curve-billed Thrasher
Toxostoma curvirostre
Plain grayish-brown thrasher of the southwest U.S. and Mexico. Look for decurved bill and fairly faint round spots on breast and belly. Undertail coverts are slightly warmer buffy. Eye color varies from yellow to orange. Occurs in deserts and open, shrubby areas. Can be shy and skulking, but often perches atop a bush or cactus to sing. More common in suburban areas and parks than other thrashers in range. Most similar to Bendire’s Thrasher. Note Curve-billed has a slightly longer and more curved bill, and breast spots are slightly larger and rounder.
Black Scoter
Melanitta americana
Plump diving duck, typically seen in flocks in coastal areas. Males are completely black with bright orange knob on the bill. Females are brown overall with pale cheek and contrasting dark cap. Note potbellied shape and rounded head in flight. Typically coastal, but migrates over land especially in the Northeast U.S. Often gathers in tight flocks. Dives frequently, feeding on aquatic invertebrates. Breeds on ponds in Arctic tundra.
Cyprus Scops-Owl
Otus cyprius
A small dark owl, intricately marked with black streaks and fine barring. Bright yellow eyes are set in a pale face ringed with black. The ear tufts can be prominent, especially when seen on a day roost, but sometimes are nearly invisible. Found in open woodlands, orchards, and parks. Active at night, when usually detected by monotonously repeated song, a single plaintive hoot that carries quite well. Within its restricted range, can only be confused with Little Owl, but separated by smaller size, ear tufts, and gray rather than brown overall coloration.
