Yellow-billed Amazon
Amazona collaria
A chunky green inhabitant of wet forests; typically found in pairs or small flocks in or near the canopy. Note this species’ yellow bill, rosy throat, and white eyering. The somewhat similar Black-billed Parrot is distinguished from Yellow-billed Parrot by its black bill, black eyering, and green throat. When the two species are together, the larger size of the Yellow-billed is evident. The characteristics noted above also separate this species from other parrots that might have escaped from captivity. Calls include a a “maa-weep” and a “mwah” that is not as harsh as the corresponding call of the Black-billed Parrot.
识别特征
The yellow-billed amazon is 28 cm (11 in) long. Its plumage is mostly green with pink over the throat, upper breast and sides of neck, and blue in the larger wing feathers. Feathers over the ears are dark blue-green. The bare white eye-rings are surrounded by a narrow rim of white plumage, which continues as a narrow band of white over the forehead. Plumage over the lores is pale blue and the fore-crown is blue. A barred appearance over the back and sides of neck arises from the green feathers having black tips and edges. The tail feathers are green with red bases. Its beak is yellow, its irises are brown, and its legs are pink. The adult male and female are identical in external appearance. Juveniles have grey on the upper mandible and are otherwise similar to adults.
分类信息
The yellow-billed was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae. He placed it with all the other parrots in the genus Psittacus and coined the binomial name Psittacus collarius. Linnaeus based his description on an account by the Irish naturalist and collector Hans Sloane that was published in 1725 in his The Natural History of Jamaica. Sloan reported that the parrots "are eaten bak'd in pyes and taste as pigeons." The Linnaeus mistaken specified the type location as "America" instead of Jamaica. The yellow-billed amazon is now one of around thirty species placed in the genus Amazona that was introduced by the French naturalist René Lesson in 1830. The genus name is a Latinized version of the name Amazone used in the 18th century by the Comte de Buffon. The specific epithet collaria, collarius is from Latin collare and means collar or neck-chain. The species is monotypic: no subspecies are recognised.

Senegal Thick-knee
Burhinus senegalensis
Very large shorebird that is similar to Eurasian and Water Thick-knees, but with a longer and heavier bill. Also note the gray mid-wing panel without a black-and-white upper border. Immature Eurasian Thick-knees can also have a simpler wing pattern similar to Senegal, and identification of those birds best determined by structure and habitat. More connected to aquatic habitats than Eurasian Thick-knee, but not as much as Water Thick-Knee. Noisy, especially at night, producing a variety of loud whistles and trills.
White-rumped Hawk
Parabuteo leucorrhous
Small raptor of montane forest in the Andes from Venezuela to Argentina, with a disjunct population in southeastern South America. Adults are black with a piercing yellow eye. In flight, look for the paddle shaped wings and contrasting white underwing coverts. The tail has contrasting black and white bands. Juveniles are buffy below with messy dark markings; note the white eyebrow and overall compact shape. Singles or pairs are uncommon over forest or adjacent clearings. Typically seen soaring or occasionally perched in the canopy.
Ayacucho Thistletail
Asthenes ayacuchensis
Poorly known thistletail found only in a small area of the high Andes east of the city of Ayacucho in southern Peru. It is brown above, gray below, with a long wispy tail and a reddish-orange chin patch. It has a darker chin patch than Vilcabamba Thistletail and Puna Thistletail, and is not known to overlap with either species. It inhabits scrub and stunted forest near treeline. Song is a rapid, high-pitched trill.
