Yellow-breasted Greenfinch

Small, compact grebe with thin pointed bill. Breeding adults have long golden tuft behind red eye. Also look for rich chestnut neck and body contrasting with darker back. In winter, grayish overall with a black cap and contrasting white cheek. Red eye visible at close range. Breeds on marshy ponds; during migration and winter, often seen on large lakes, bays, and open ocean. Compare with Eared Grebe, especially in winter. Horned is thicker-necked and larger-headed. Also note Horned's flatter crown, white cheek contrasting with dark cap, and pale tip on bill.

Small, sparrow-like bird. Male has mostly black head with large white whisker mark; female is olive-brown on back and pale yellowish below with a dull yellow bill. Found in open marshlands and disturbed habitats with long grass, especially near water; often seen in flocks, feeding on grass seeds. Song is a staccato series of about 10 notes on one pitch. Most similar to Lined Seedeater, but male Lesson’s lacks a white stripe on crown; females of the two species are identical and not safely identified unless accompanied by males. Females are best told from other seedeaters (except Lined) by strong yellowish wash on underparts and relatively small, dull yellow bill.

Distinctive rounded-tailed rufous-brown bird of riverine habitats. Narrow buffy eyebrow and buffy streaks on cheeks and breast. Upperparts rufous-brown and underparts olive-brown; rich chestnut in chin, wings, rump, and tail. Rare, usually in pairs, found from understory to mid-level in riverine forest in very restricted range. Voice consists of repeated “CHEUP” notes, mostly in duet. Similar to Delta Amacuro Softtail (no range overlap), which is more streaked (including the head) and lacks buff eyebrow; Speckled Spinetail has a buffy (not orange) chin, paler head and breast with dark speckling, and a rufoud cap. Endemic to the Orinoco River and nearby tributaries in southwestern Venezuela and eastern Colombia.
