Hemprich's Hornbill

Ornate medium-sized woodpecker. Moss-green with blood-red wings and neck. Back edge of head and neck are brightened by a sunny yellow crest. Black-and-white “checker” throat is not particularly obvious. Prefers mature lowland and hill forests; seldom seen in secondary growth or sparsely-vegetated edge. Typically forages at mid-levels of forest, frequently singly but also in mixed flocks or pairs. Gives loud, insistent “nyeh” notes and a strident “choo-yik!”

An antbird with a very restricted distribution in the Araguaia Valley. Males are black with white wing bars and white tips to the tail, while females are similar but gray and slightly streaked on the breast. Occurs in gallery forest and adjacent second growth, where it forages in the understory and does not join mixed-species flocks. Males give a series of staccato notes and are sometimes joined in a duet by females giving high-pitched notes.

A skulky, dull brown warbler with a long and graduated tail, a pale grayish eyebrow, and a throat that is lightly streaked. It creeps around mouse-like in thick undergrowth and tangles in forest and forest edge. It is also found in isolated pockets of scrub, often adjacent to streams, and is frequently detected and identified by its song, mostly delivered between September and December: 2-3 sweet “tsiit” notes followed by a loud trill of 15-20 harsh “tchui” notes. It also has a strident chipping alarm call “tddd-ddr-ddr-ddr-ddr-tt.” The similar Knysna Warbler differs from Barratt’s Warbler by its shorter tail, darker underparts, less pronounced throat streaking, and different song.
