Puerto Rican Vireo

Small, fruit-eating flycatcher found in lower to middle levels of humid forest. Most common in the mountains, but occasionally seen in lowland areas. Yellow belly, large spot behind eye, and streaky neck are all good ID features. Often seen following mixed species flocks, plucking berries from fruiting trees. Song is an incredibly high-pitched siren-like whistle that requires good hearing to be able to detect. Formerly treated as a subspecies of Olive-striped Flycatcher; note Olive-streaked Flycatcher’s limited range in Costa Rica and far western Panama.

Drab and lethargic flycatcher of extensively forested regions; most common in hills and mountain valleys but also ranges into lowlands. Sexes are similar: brown above and white below with tan suffusions on the flanks and neck. Bicolored bill is long with a noticeably hooked tip. Makes sallies from a typically hidden perch to catch insects; generally solitary and unwilling to join mixed flocks. Song, a series of descending whistles, carries well.

A locally common but easily overlooked flycatcher of forest and forest edge. Has a distinctive crested flycatcher shape but more warbler-like behavior, sitting laterally on perches and moving its tail around as it forages. Male has a glossy black head, throat, back, wings, and tail, with a pale gray belly. Female is pale gray all over, slightly darker on the back, wings, and tail, with a blackish cap. Song is an ethereal, hollow “wo-wo-wo-wo-wo-wo-wo-wo-wo,” rising in pitch, reminiscent of a fast White-spotted Flufftail. Calls include harsh chatters and rattles.
