Newton's Sunbird

An overall sooty-colored cuckooshrike with broad white tips to the tail feathers. Male is dark sooty-gray with a slaty sheen, slightly paler on rump. Underparts paler toward tail; wings black. Female is very similar to male, but paler in general, often weakly barred with dark and pale gray on underparts. Male has a black mask, while female has dark lores and a faint eyering. Juvenile is blackish-brown above and brownish-gray below, heavily scaled whitish all over, with broad white tips on wing feathers. Immature like female, but more strongly and extensively barred below. Song is a loud series of whistles “pe-pe-pe-peew-peew-pew”; sometimes the starting notes are skipped. Found in all types of woodlands, including broad-leaved forests, sometimes even near cultivation during non-breeding season.

Chunky, bull-headed puffbird of lowland and foothill rainforest east of the Andes to far western Brazil. Underparts are pale with dark, vertical streaks. Also note stout, yellowish bill, and brown cap and back. Very similar to Eastern Striolated-Puffbird (limited overlap in Brazil and possibly Bolivia), but has thicker streaks on underparts. Singles or pairs perch motionless for long periods high in the canopy; usually heard before seen. Typical song is a whistled “wip wip-whirrr?, whurrrr”, with the other member of the pair responding at slightly different pitch.

A nest parasite that lays its eggs in the nests of Rock Firefinches. Breeding males are black with green iridescence and a pale brownish panel in the wings. Females and non-breeding males are streaky and brown on the back and pale below, with a bold facial pattern. The bill is whitish and the legs pale purple. A scarce, local, and poorly known species. Found in rocky areas within savanna. Given current knowledge, can only be confidently identified by vocalizations. Imitates the vocalizations of its host, Rock Firefinch, including soft “teew” whistles, a descending trill, “tep” notes, and “pit-pit-pit” calls. These are often mixed into a scratchy jumble of high-pitched notes.
