Gray-crested Finch

Medium-sized pinkish-brown dove with bright red eyes. “Collar” is black with a white upper margin. Favors mangroves and other open forests and forest edge, occasionally venturing into areas of human habitation; generally uncommon throughout much of its range. Gives a deep throaty purr.

A small seed-eating species of forest edges, open woodlands, and nearby weedy areas; usually found in groups of two to five birds. Both sexes have bright yellow-green shoulders and a buff vent, which are diagnostic but can be difficult to see. Otherwise, the Black-faced Grassquit is rather similar, but can be distinguished by its slimmer bill and duller back. Furthermore, male Yellow-shouldered Grassquits have an entirely black head, whereas black is limited to the face on the Black-faced Grassquit. The song is a series of four or five high-pitched buzzy notes that either rising or dropping in pitch, followed by one to three notes at another different pitch.

Highly social inhabitant of lowland forests, unlike any other tit in both size and coloration; coal-black with a bright yellow belly and sharply upswept crest. Closer in size to a medium-sized bulbul than to a Japanese or Coal Tit. Tends to stick to the canopy, where it readily associates with other species in mixed flocks. Very vocal, often giving squeaky, shrill calls. Song consists of repeated high-pitched whistles, sometimes with an inflected quality.
