Marmora's Warbler

A medium-sized tern of the tropical Pacific. Similar to Sooty Tern, but the back is gray (not black) and the white patch on the forehead extends behind the eye. Note deeply forked tail. Nests on the ground and occasionally on ledges on tropical islands. Rarely seen from shore.

A small, charismatic bird of tepui highland forests. Note orange-rufous face and breast, short tail, and bold wing bars. Found only at higher elevations (above 1000 meters) in understory of humid forest with lush growth of mosses and epiphytes; usually in pairs that may join mixed-species flocks but are often found away from them. Forages deliberately, making short flights between perches and peering about for insect prey. Voice is a hollow, rolling purr, descending in pitch and usually preceded by one or two short notes; it is given intermittently and often in duet by a pair. A distinctive bird and unlikely to be confused with other species in its limited range.

A very slender gray-brown swift with a long, deeply forked tail that is often held closed, making it look needle-like and pointed. The erratic flight pattern, with frequent direction changes and rapid wingbeats on long, scythe-shaped wings, is distinctive. Less gregarious than other swifts; usually found in pairs or small flocks, and association with other swallows and swifts is usually only fleeting. Forages over a wide variety of habitats with palms, including savanna, coastal scrub, towns, villages, cultivated areas, forest edge, and clearings, from sea level up to 1800 meters of elevation, preferring lowlands. Nests and roosts in palms and uses its tiny legs with hook-like claws to cling to the undersides of fronds. Gives a high-pitched, metallic “tre-tit-tit-tit-tit-tit-tit-tit” call, solitarily or in unison with others. Separated from other swifts by its longer and thinner tail.
