Puff-backed Bulbul

One of the world’s rarest and most endangered hummingbirds, found only at extremely high elevations in Colombia’s Santa Marta Mountains. It does not occur in the areas typically visited by birders, and seeing one requires a multi-day camping expedition over very steep terrain. Adult male’s green and blue beard, black and white head pattern, and shaggy crest are distinctive. Female and younger males lack the crest and beard, and can be recognized by their size, short bill, and white collar. Feeds in flowering bushes in and around high elevation grassland; often clings to flowers while feeding.

A small Hawaiian honeycreeper of forests on Oahu. Males are bright yellow and females are grayer with two whitish wingbars. The bill is thicker and more curved than that of Warbling White-eye. Occurs in native and non-native forests, parks, and some suburban areas near mountains. Moves quickly among leaves and small branches in the understory and forest canopy in search of nectar, insects, and fruit. Song is a trill that does not change in pitch or speed. Call is a nasal “chee.”

Small two-toned flycatcher, olive-brown above and yellow below. Note the rufescent crown patch. Found in tall-grass marshes, especially those with sedges. Typically difficult to locate, but during migration can be found in various areas with tall grass. The call is a series of nasal squeaky notes: “chek, chek, chek, chek-chick-chick-chiquetik.” The rather similar Dinelli's Doradito has a more olive-colored, less brownish back.
