Sulphur-breasted Parakeet
Aratinga maculata
A medium-sized, colorful parakeet of eastern Amazonia, local but often fairly common. Plumage is generally yellowish, with greenish upperparts, wings, and tail. Notice the orangish coloration around the eye. Usually in small flocks, foraging in open or semi-open areas with short trees, and sometimes humid forest edges.
识别特征
The sulphur-breasted parakeet is about 30 cm (12 in) long and weighs about 110 g (3.9 oz). The sexes are alike. The adults' crown and mantle are pale greenish yellow. Their wing coverts range from yellow through green to deep blue; the flight feathers are also deep blue on their upper side. Their tail's upper side is mostly green, with blue tips on the inner feathers and progressively more blue outwards to the entirely blue outermost pair. Their head below the crown and their underparts are mostly yellow, with orange through the eye and on small areas of the belly and flanks. The undersides of their flight feathers and tail are blackish gray. Their iris is dark gray surrounded by bare bluish gray skin, their bill black, and their legs and feet dark brownish. Juveniles have a green head, mantle, and wing coverts. The species closely resembles the sun parakeet but has less orange and more green.
分类信息
The sulphur-breasted parakeet was originally described as Psittacus maculatus. For many years the early specimens were thought to be immature sun parakeets or hybrids, and the current specific epithet maculata was thought to be invalid. A 2005 paper described what was thought to be a new species A. pintoi but in 2009 the "new" species was determined to be the previously described A. maculata. The reclassification was widely accepted but not without some dissent.<p>The sulphur-breasted parakeet is monotypic.

分布与栖息地
The sulphur-breasted parakeet has two disjunct ranges. It is found in Brazil's Pará state north of the lower Amazon River between the Maicuru and Paru rivers, and also in Suriname's Sipaliwini Savanna. It probably also occurs in the Brazilian state of Amapá but has not been confirmed there.<p>The sulphur-breasted parakeet inhabits open to semi-open landscapes, typically those with sandy soils and scattered trees and bushes. It also occurs in gallery forest, and occasionally in orchards. In elevation it ranges as high as 1,400 m (4,600 ft).

Reunion Bulbul
Hypsipetes borbonicus
A medium-sized dark gray bird with a white eye, a black cap, and a carrot-colored bill. Endemic to the island of Reunion. Found in humid forest as well as secondary forest and forest dominated by exotic trees; now mostly confined to middle and high elevations. Often in small, noisy groups. Somewhat similar to male Reunion Cuckooshrike, but easily separated by the orange bill and pale eye. The song is an unmusical but varied series of rattling, metallic, and scraping notes, often given from a high perch. The calls include a “chek” note and a long mew.
Undulated Antshrike
Frederickena unduliger
Magnificent dark antshrike of mature upland rainforest. Has a large head with a crest and strongly hooked bill. Males are slaty gray with fine black barring; females are tawny orange with fine black barring. Larger than most other antshrikes and antbirds in its range. Forages singly or in pairs in open understory, and seems to be somewhat rare throughout its range. Its song is a gradually rising series of low whistles given at a steady pace.
White-tailed Nightjar
Hydropsalis cayennensis
This rather long-tailed nightjar is found in open grassy or shrubby habitats from Costa Rica across much of northern South America. Both sexes show a distinctive buffy nape. Males have extensive white in the tail, especially visible in flight. Strictly nocturnal; single individuals are most often seen sitting on the ground at night, sallying up to catch flying insects. Listen for the song, which begins with a sharp “pik” note, followed by a longer whistled “seeeee,” ascending and then descending.
