Yellow-browed Bunting

Largest tern in the world; widespread but typically uncommon. Thick, bright-red bill is distinctive; most have small dark marking near the tip. Note solid black cap in summer which turns to black streaks in winter. Juveniles have V-shaped markings on the upperparts. Feeds by cruising over lakes, rivers, estuaries, and reservoirs looking for fish, then plunging to catch them. Smooth wingbeats, more gull-like than choppy flight of small-bodied terns. Very vocal, giving loud raucous screams. Compare especially with Royal Tern, which is slightly smaller and more slender, and has a thinner, more orangey bill.

Fairly small antshrike. Males are dark gray with a black throat. Females are tinged brown above and tawny below with a contrasting whitish throat. Found in the understory of lowland humid forest. Often leads mixed-species flocks; occasionally attends army-ant swarms. Sings a series of gradually ascending notes that ends with a harsh final note. Similar to Cinereous Antshrike, which can occur in the same flocks, but differs in throat color and in song.

A dapper waxbill of low elevations found in flocks along roadsides, near villages, and along the forest edge, sometimes with other waxbills. Similar to Black-crowned Waxbill, but Black-headed has a unique combination of a red rump and flanks and a dark vent. Black-headed is found at lower elevations than the visually similar Kandt’s Waxbill where ranges overlap. Black-headed often gives high-pitched “seet seet seet” calls as it forages.
