Amazonian Elaenia

Recently described Amazonian antwren. Males are gray with a bold white eyebrow and a black crown, wings, and tail. Females have white spots on a black crown and a rusty forehead. Found in humid forest, including seasonally flooded forest along big rivers and white sand forest, foraging from the middle levels to the canopy. Usually accompanies mixed-species flocks in the canopy. The song is a soft rolling trill. The rather similar male of the Aripuana Antwren has less black on the upperparts, and females have a paler forehead; Aripuana’s song is similar, but with fewer notes.

Small honeyeater of coastal heathland in southern Australia. Brownish above, pale below, with white brow, tan crown, and black cheeks that extend down onto the breast, ending in black stippling. Yellow in primaries and salmon underwing evident in flight. Juvenile brownish above, paler below, with yellow in wing. Call a mournful piping whistle, with some tones recalling Spiny-cheeked Honeyeater.

A bulbul-sized olive-brown bird that sports a diagnostic all-red bill and a red eye surrounded by a fleshy yellow wattle. The juvenile lacks the bright bill and eye coloration. Small groups occur in savanna and farmland, where they require large wild ungulates and domestic stock to forage on; they clamber agilely over host mammals, gleaning ticks, mites, and other ectoparasites, and occasionally drinking host blood. As they fly between large mammals, they give a distinctive “tsik-tsik” call. The similar Yellow-billed Oxpecker differs from Red-billed Oxpecker by having a yellow bill base and pale rump and lacking an eye-wattle.
