Black-spectacled Brushfinch

Rather small antbird with a disjunct distribution. Males have a yellow face and underparts with a black crown, eye-line, and streaks on the breast. Females have a yellow streaked crown.  Southeastern subspecies has ochraceous lower underparts. Song is a descending and decelerating series of fluted notes becoming harsher at the end. Found in the understory of humid forests, often in areas of transitional forest or poor soils. Rarely accompanies mixed-species flocks. The similar Spix's and Peruvian Warbling-Antbirds have white breasts, and the song of Peruvian is somewhat slower-paced.

Small, rather chunky but long-tailed bird of tropical forest and woodland in lowlands and foothills; endemic to western Mexico. Feeds at all levels, often at fruiting trees and bushes with other vireos and fruit-eating birds. Like most vireos, generally rather sluggish. Bright yellow-and-greenish plumage, plus cocked tail, strongly suggest smaller and more lightly built Wilson’s Warbler, but note the vireo’s broad pale eyebrow, stouter bill, and stronger blue-gray legs.

Tiny and active sunbird of forest edges, parks, and gardens; ranges from Sulawesi east to the northern Moluccas, New Guinea, and northeastern Australia. Both sexes have a plain olive back, a yellow belly, and white tail edges that are flared out in flight. The male flashes an iridescent blue throat while the female has a yellow throat and eyebrow. In parts of range, female Sahul may be confused with female Black Sunbird; note that species’ unmarked gray head and shorter, less curved bill. Gives a buzzy, twittering song, as well as a rising “dwee”, a familiar sound even in cities. Formerly grouped with other, closely related species under “Olive-backed Sunbird.”
