Yellow-faced Parrot
Alipiopsitta xanthops
A very distinctive mostly green parrot with a yellow face, a yellowish belly, and orange-red thighs. Note the dark upper bill. Tends to prefer drier and more open areas than most other large parrot species in its range, but also found in savannas and dry forests (caatinga). Flight call is repeated screeching “crrreeh.”
识别特征
Measuring about 27 cm (11 in) in length, the yellow-faced parrot has a stocky body and short tail. It is a predominantly green and yellow-plumaged bird that in adults has a yellow crown, lores, cheeks and auriculars. The rest of the head, upperparts and chest are green with some yellowish-green scalloping. The sides of the belly are often mottled orange and yellow, and the belly is often yellow. However, there are significant variations in the amount of yellow to the underparts, and some show virtually none. The wings are predominantly green, occasionally with some yellow spots. There is blue edging on the primary coverts. The central feathers of the short tail are green, while the lateral ones are more yellow-green and have orange-red bases. The bill is yellowish-horn with a dark culmen, the cere is pinkish, and the iris is yellow. The legs are light grey. There is no sexual dimorphism; the male and female are alike in plumage and size. Immatures have less yellow to the head.
分类信息
The German naturalist Johann Baptist von Spix first described the species in 1824 as Psittacus xanthops. Its species name is derived from the Ancient Greek xanthos "yellow", and ops "face". For many years, it was placed within the genus Amazona, although Alípio de Miranda Ribeiro proposed the new genus Salvatoria in 1920 due to differences in the bill and plumage. A 1995 study showed its distinctness genetically, followed up by more data which showed it to be much more closely related to the short-tailed parrot (Graydidascalus brachyurus) and to the members of the genus Pionus. Following this discovery, it was briefly placed in the genus Salvatoria again, until this name was found to be pre-occupied by a group of polychaete worms from the superfamily Nereidoidea, thus leading to the transferral of the yellow-faced parrot to the new genus Alipiopsitta.

分布与栖息地
The majority of its range is in central and eastern Brazil, where found from Maranhão and Piauí to São Paulo and Mato Grosso do Sul. It inhabits the cerrado on the plateau of Brazil, as well as the dryer Caatinga scrubland. There are two records from Beni in northeastern Bolivia. Despite occasionally being listed for Paraguay, evidence supporting its presence in this country is lacking. Within its range it appears to be semi-nomadic. Much of its habitat is being converted to agricultural land and the populations are declining.

White-vented Violetear
Colibri serrirostris
Medium-sized hummingbird with a spangled green body, white vent, and prominent violet-blue ear patches, which are sometimes erected. Mostly found in wooded savannas and forest edges, and frequently visits feeders.
Iringa Akalat
Sheppardia lowei
A rather small, demure understory denizen resembling a cross between a robin and a flycatcher. Mostly dull brown with a buffy throat and a short eyebrow. Juvenile is more mottled. A highly local bird found singly and in pairs in dry and wet primary and secondary montane forest in a narrow range along the Udzungwa and Livingstone mountains escarpment between 1350 and 2500 meters of elevation. Sits for long periods, sallying to catch insect prey, or forages on the ground, often in the company of ants and other ant-following birds. Sings a variable medley of quavering high-pitched notes, “tseet-teet-tsereet-teeet-tsureet,” that is sweet without being tuneful. Calls include an invariable piping “wheet” uttered once a second. Alarm call is a grating “drrrzzt, drrrt, drrrt.” May be mistaken for a flycatcher, but its furtive nature and preference for thick understory are unique within its range.
Rufous-vented Whitetip
Urosticte ruficrissa
Rare hummingbird of cloud forest on the east slope of the Andes. Male is mostly green with darker throat and white tips to the inner tail feathers that combine to form a round spot. On female, note green scaling on white underparts, white mustache stripe, white tail corners, and buff tinge on vent (but not on thighs). Female very similar to female Booted Racket-tail but is more heavily scaled on throat and has white thighs. Typically found at forest edge or in clearings, feeding at any height, and occasionally visits feeders.
