Hispaniolan Parakeet
Psittacara chloropterus
A sleek, medium-large, gregarious species of woodlands that sometimes ventures into agricultural and urban areas. Its overall green plumage, long, pointed tail, and stout bill eliminate all other species in range. In overflight, it often appears green with a red slash on each forewing. Most common call is a series of squeaks that takes on a twittering quality when given by an excited flock.
识别特征
The Hispaniolan parakeet is 30 to 33 cm (12 to 13 in) long and weighs 144 to 147 g (5.1 to 5.2 oz). The sexes are alike. Adults are mostly green that is more yellowish on their underparts. Some have a few red flecks on their head. The bend and edge of their wing and their outermost underwing coverts are red. The undersides of their flight feathers and tail are dull yellowish. Their eye is surrounded by bare white skin. Immature birds have little or no red on the wing.
分类信息
The Hispaniolan parakeet was for a time placed in the genus Aratinga but from about 2013 has been in its present genus Psittacara. The International Ornithological Committee, the American Ornithological Society, and the Clements taxonomy consider the Hispaniolan parakeet to be monotypic. They previously treated what is now the Puerto Rican parakeet (P. maugei) as a subspecies. BirdLife International's Handbook of the Birds of the World retains that former treatment. (The Puerto Rican parakeet is now extinct; it had occurred on Mona Island and probably on the main island of Puerto Rico.)<p>The Hispaniolan parakeet has at times been suggested to be conspecific with the white-eyed parakeet (P. leucophthalmus); it and the Cuban parakeet (P. euops) form a superspecies.

分布与栖息地
The Hispaniolan parakeet formerly ranged across most of the island of Hispaniola. As of 2020 it is known in the Dominican Republic mostly from the Cordillera Central, Sierra de Bahoruco, and a few urban centers. It is very rare in Haiti, where in the early 2000s it was found in the Chaîne de la Selle and Massif de la Hotte with scattered records elsewhere. The species was introduced to Puerto Rico and Guadeloupe. There are no eBird records from the former island and very few from the latter.<p>The Hispaniolan parakeet inhabits a wide variety of landscapes including lowland and montane forest, savanna, open woodlands, secondary forest, croplands, and urban centers such as Santo Domingo. It is most common in humid montane forest. In elevation it ranges from sea level to 3,000 m (9,800 ft).

行为
The Hispaniolan parakeet is not migratory.<p>The Hispaniolan parakeet's diet has not been fully described. It is known to feed on fig (Ficus) fruits and reported to feed on fruits, seeds, and flowers of a variety of other plants and trees. It has also been reported as a significant pest on maize (Zea mays) crops.<p>The Hispaniolan parakeet nests in cavities in trees or arboreal termitaria. Almost nothing is known about its breeding biology in the wild. In captivity it lays a clutch of three or four eggs, with an incubation period of 20 to 23 days and about eight weeks to fledging.<p>The Hispaniolan parakeet makes a "kree" call "with a grating noisy sound quality" both in flight and when perched.

East Coast Akalat
Sheppardia gunningi
Variable small robin-like skulker of the forest floor and mid-story. Upperparts are rusty-brown and underparts are buff-apricot to rufous (varying in intensity); some populations have a white belly and throat. Broad eyebrow is blue-gray with a white spot above the lores. Pairs can be common but inconspicuous in lowland primary and secondary forest, preferring the understory, but when vocal it sits calling from mid-canopy. Song a sweet rolling repeated “tuwuyu-teelu”. Does not overlap with other akalats in range or habitat choice.
Lark-like Bunting
Emberiza impetuani
A dull, nondescript, slender buffy bunting. Subtle features include a rusty wing panel, a pale spot near the ear, a buffy eyebrow, and a small pale silvery bill. Pairs can be low-density residents, but typically the species is nomadic, and large flocks irrupt into the semi-arid Karoo, Kalahari, and Namib after rainfall events; but it may reach savanna and other atypical habitats, particularly in drier years. It prefers areas with bare stony soil and often is found close to pools of drinking water. The song is a short series of varied scratchy trills, but the distinctive flight call is short, dry, crisp one-note “tec” which often betrays its presence. It often flocks with other seedeaters, lacking the black belly patch of the otherwise similar female sparrow-larks.
Yellow-bellied Flycatcher
Empidonax flaviventris
Small flycatcher, extremely similar to several other species. Generally shy and inconspicuous; breeds in spruce forests often near boggy areas. Migrants tend to be found in denser wet areas within woods. Olive-greenish above with distinctive yellow wash on throat and belly. Black wings with bold white wingbars. Nearly identical to Western Flycatchers, but limited range overlap. Within range, main confusion species is Least Flycatcher. Bright yellow throat and belly is usually enough to identify Yellow-bellied Flycatcher, but some worn birds can be very similar. Song is similar to Least Flycatcher ("chebek") but more slurred, with a soft buzzy tone. Not frequently repeated like Least Flycatcher. Soft whistled call note, "pwee," unlike Least's sharp "whit" call.
