Green-cheeked Parakeet
Pyrrhura molinae
Long-tailed parakeet with a brown crown and green cheeks; depending on the subspecies, the breast is either white or yellow, and the maroon belly patch is often reduced. Found in woodland and gallery forest; usually seen foraging or flying in noisy groups.
识别特征
The green-cheeked parakeet is 25 to 26 cm (9.8 to 10 in) long and weighs 62 to 81 g (2.2 to 2.9 oz). The sexes are the same. Adults of the nominate subspecies P. m. molinae are dull brown from forehead to nape and have green cheeks, ashy brown ear coverts, and a creamy white ring of bare skin around the eye. Their upperparts are green. Their chin, throat, and the sides of their neck are a scaly brown and whitish. Their belly is dull reddish and their lower flanks and vent area are green. Their wing is mostly green, with bluish flight feathers. Their tail is dull reddish. Immatures are similar to adults but without the red belly.<p>Subspecies P. m. phoenicura is green on the upper surface of its tail's base. P. m. restricta has a blue collar, a blue tinge on its cheeks, and a smaller red belly patch than the nominate. P. m. hypoxantha has a paler crown and less distinct scaling on the breast than the nominate. P. m. australis is paler than the nominate and has a larger red belly patch. P. m. flavoptera is orange to red at the bend of the wing and on the carpal edge and is otherwise like the nominate.<p>A small number of individuals of P. m. hypoxantha have mostly yellow underparts.
分类信息
The green-cheeked parakeet has these six subspecies:<p>Subspecies P. m. hypoxantha was previously known as P. m. sordida and was sometimes treated as a separate species. However, by the principle of priority the older name hypoxantha replaced sordida. The green-cheeked parakeet has also been treated as conspecific with the maroon-bellied parakeet (P. frontalis).<p>The green-cheeked parakeet is most closely related to the maroon-bellied, pearly (P. lepida), and crimson-bellied (P. perlata) parakeets.

分布与栖息地
The subspecies of the green-cheeked parakeet are found thus:<p>The green-cheeked parakeet inhabits lowland woodlands and forest (chiefly deciduous), secondary forest, and gallery forest in the lower elevations of the Pantanal and humid subtropical forest as high as 2,000 m (6,600 ft).
- 迁徙
- Vertical migration
行为
The populations of green-cheeked parakeet breeding in higher elevations move to lower ones in winter.<p>The green-cheeked parakeet has a varied diet that, in the wild, consists of fruits, seeds, flowers and, to a lesser extent, nectar and leaves.<p>The green-cheeked parakeet's breeding season in Argentina includes February, but its season elsewhere has not been defined. It nests in tree cavities. In captivity the clutch size is four to six eggs, the incubation period is 22 to 25 days, both sexes incubate the clutch, and fledging occurs about seven weeks after hatch.<p>The green-cheeked parakeet's flight calls "comprise rather high-pitched notes with a grating quality and usually given in fast series, e.g. "krree krree krree", but also single "kuree" notes." From a perch it "utters high-pitched, more melodious notes, such as a bisyllabic "rrekeet" or "keew"." However, perched birds are often silent. Flocks in flight "call frequently and simultaneously, producing a noisy, harsh and piercing chattering."

Gould's Toucanet
Selenidera gouldii
Beautiful small, multicolored toucan. Males have a black crown and underparts; in females, the black is replaced by chestnut. Note the black and orange patches on the bill. Inhabits lowland humid forest, seasonally flooded forest, gallery forest, and old second growth. Forages from middle levels to the canopy, usually in fruiting trees. Call is a deep and somewhat slow series of “ggrawnk” to “ggrraaw” notes, easily overlooked.
Transvolcanic Jay
Aphelocoma ultramarina
Rather large, blue-and-gray jay of highland pine and pine-oak forest endemic to highlands of central Mexico; occurs in transvolcanic belt from Volcánes de Colima in the west to Volcán Orizaba in the east. Typically travels in wide-ranging flocks of 5–25 birds, mainly at middle to upper levels in trees. Appreciably larger and broader-winged than Woodhouse's Scrub-Jays, with plainer plumage (lacks dark mask, whitish eyebrow, and partial dark collar of Woodhouse's Scrub-Jay). Noisy calls carry well.
Pale-footed Bush Warbler
Hemitesia pallidipes
A retiring warbler of densely vegetated forest edges, lightly wooded slopes, and clearings in foothill to montane regions; favors areas with thick ground vegetation. Dull and unremarkable to look at; plain brown above and paler brown below, with a white throat and eyebrow. More contrastingly marked than Brownish-flanked Bush Warbler; smaller and stouter than Manchurian and Japanese Bush Warblers. Song is what sets it apart: a sharp note followed by a quick bout of chattering and squeaking.
