Tui Parakeet
Brotogeris sanctithomae
Small, short-tailed parakeet of lowland rainforest. Green with yellow forehead patch, light eye, and peach-colored bill. Also has blue wing feathers visible in flight, like many small green parakeets. Almost always found in pairs or groups, and is quite loud in flight, giving harsh “kreet” calls. Similar to Cobalt-winged Parakeet, but has a light eye, a yellow forehead, and slightly harsher calls.
识别特征
The tui parakeet is 17 to 19 cm (6.7 to 7.5 in) long and weighs an average of 59 g (2.1 oz). Adults are mostly green that is yellower on the rump and underparts. They have yellow lores and forehead and a bluish tinge on the face. Their primaries are a darker green than the body and bluish on their underside. Their bill is brown. Subspecies B. s. takatsukasae differs from the nominate only by adding a yellow streak behind the eye. Immature birds are essentially the same as adults.

分布与栖息地
The nominate subspecies of the tui parakeet is found in the Amazon Basin of extreme southeastern Colombia, eastern Peru, northern Bolivia, and Brazil east to the Rio Madeira. Undocumented sight records in eastern Ecuador lead the South American Classification Committee of the American Ornithological Society to treat it as hypothetical in that country. Subspecies B. s. takatsukasae is found along the lower Amazon from the Rio Madeira and Rio Negro to the Atlantic at the Amazon's mouth. The species mostly inhabits semi-open landscapes like secondary forest, grasslands with some woodlands, riverbanks and islands with dense scrub, and the edges of várzea forest.

行为
The tui parakeet is believed to be sedentary.<p>The tui parakeet feeds on fruit and blossoms from a variety of plants including palms. It also feeds in manioc and sugarcane plantations.<p>The tui parakeet's breeding season is not well defined but appears to be April to July in Colombia. Nest cavities in arboreal termite nests have been documented. One nest held six nestlings. The typical range of clutch size, the incubation period, the time to fledging, and details of parental care are not known.<p>The tui parakeet's calls include "a high-pitched “klee”, shrill “chree” or bisyllabic “chree-chree” [and a] fast chattering series “cra-cra-cra-cra-cra”." Members of a flock often call simultaneously.

Gray-crowned Rosy-Finch
Leucosticte tephrocotis
The most widespread rosy-finch. Body is the color of milk chocolate. Look for pink highlights in the wings, tail and belly. Several different populations; some have gray wrapping around the back of the head only above the eye, others have entirely gray cheek. Breeds at the highest elevations; descends to lower elevations in winter. Often in mixed flocks in winter with other rosy-finches. Feeds on seeds and insects. Look for them foraging on alpine snowfields. Visits feeders, primarily in winter.
Pale-vented Pigeon
Patagioenas cayennensis
Large pigeon of marshy savannas, riversides, open areas with scattered trees, locally even in towns, such as Villahermosa, Mexico. Gray head contrasts with pinkish body, and whitish belly does not contrast strongly with plain grayish tail; compare darker Red-billed Pigeon, which often occurs in same areas but prefers drier and more forested habitats. Also note black bill of Pale-vented, and subtly distinctive song: after long introductory coo, repeated phrase is typically a 3-syllable "who’koo-koo", unlike 4-syllable "oo’koo-koo-koo" of Red-billed.
Yellow-crowned Elaenia
Myiopagis flavivertex
Small, inconspicuous bird of coastal swamps and seasonally inundated forests. Yellow crown is essentially impossible to see under most viewing conditions; note dull overall appearance, indistinct wing bars, and longish tail. Inhabits upper levels of tall forest; also occurs in abandoned plantations and other disturbed habitats, where it may be found closer to the ground. Feeds on insects and fruit. Most similar to Greenish Elaenia but has more prominent wing bars; Forest Elaenia is more clean-cut, with a stronger facial pattern and white crown patch. Explosive song is a decelerating cackle; it is distinctive once learned and usually the most reliable indicator of this species’s presence.
