Vulturine Parrot
Pyrilia vulturina
Medium-sized, largely green parrot with a striking head pattern. The head is featherless with a combination of orange, black, and yellow bristles. Note the orange shoulder and, in flight, the red underwings. Found in the canopy of humid forest. Call is a distinctive nasal series of “tree ... trayaweet” notes.
识别特征
The vulturine parrot is 23 to 25 cm (9.1 to 9.8 in) long and weighs 138 to 165 g (4.9 to 5.8 oz). The adult's face is mostly bare black skin, with yellowish lores and a collar of yellow feathers and a band of black feathers below that. Their upperparts are green with a reddish orange shoulder. Their breast is olive-yellow, their belly green with some blue edges to the feathers, and their lower thighs yellow. Their primaries are black with green edges and their carpal's edges and underwing coverts are red. Their tail's upper surface is green with blue tips and the lower surface green and yellow. Immature birds have green feathered heads with yellowish around the lores and eye and without the adult's yellow collar.
分类信息
Until about 1970 the vulturine parrot had been treated as the only member of genus Gypopsitta before being moved into Pionositta with the pileated parrot (P. pileata) and six other parrots species. All but the pileated parrot were moved into genus Pyrilia in the early 21st century.<p>In 2002, what had been thought to be the immature plumage of the vulturine parrot was determined to be a separate species, the bald parrot (Pyrilia aurantiocephala).<p>The vulturine parrot is monotypic.

行为
The vulturine parrot's movements, if any, are not known.<p>Little is known about the vulturine parrot's foraging behavior or diet, but it is suspected that the bare head is an adaptation to avoid feather-matting from large sticky fruits.<p>Nothing is known about the vulturine parrot's breeding biology.<p>The vulturine parrot's flight call is "a slightly nasal rhythmic “tree ... trayaweet” or simply “trayaweet”." It makes "a wide variety of calls, ranging from nasal yelps or barks to more melodious whistles and whining sounds, as well as more typically parrot-like calls" when perched.

Red-bellied Grackle
Hypopyrrhus pyrohypogaster
Unmistakable Colombian endemic: large, long-tailed, and all-black with a bright red belly and piercing yellow eye. Sexes similar. Found in small flocks in the canopy of cloud forest from around 1,000–2,400 m, sometimes in mixed flocks with jays or caciques. Listen for loud shrieks and gurgles.
Mayr's Swiftlet
Aerodramus orientalis
A grayish-brown swiftlet, paler beneath, darker above with a faintly bluish tinge, with a variably grayish rump. Very poorly known from a few specimens and field observations. Generally occurs between 900-1200 meters of elevation, but has been seen at sea level. Very similar to White-rumped Swift, but has a darker gray rump and is much larger. Vocally unknown.
Allpahuayo Antbird
Percnostola arenarum
Scarce antbird described to science in 2001. It is found in lowland rainforest in northeastern Peru, only in areas with white, sandy soil. Male is gray with a black throat and white wingbars. Female has gray upperparts with tawny underparts and wingbars. Very similar to Black-headed Antbird, and best identified by voice, range, and habitat. Inhabits dense understory, often in areas with lots of palm saplings. Song is a fairly rapid series of ringing notes, higher-pitched and faster than the song of Black-headed Antbird.
