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).

行为
The sulphur-breasted parakeet is generally a year-round resident but does make some local movements.<p>The sulphur-breasted parakeet typically forages singly and also in groups of up to about 10 individuals. It feeds on fruit, seeds, and flowers.<p>The sulphur-breasted parakeet nests in tree cavities. Active nests have been found in April and September; both were in dead Hymenaea trees and one of them contained a single egg. Nothing else is known about the species' breeding biology.<p>The sulphur-breasted parakeet's call has been described as a "high-pitched shrill screech of 2–3 notes, 'screek screek screek' ", and also as a "sharp, very high shrieking, like 'eeuwt-uht-uht' ".

Galapagos Rail
Laterallus spilonota
Small, terrestrial bird that is endemic to Galápagos. Adult is dark gray with a brown back, red eyes, and fine white speckles on the rear half of the body. Juvenile is mostly gray and lacks white speckles. Now found only at higher elevations in the interior of larger islands, but formerly also occurred in coastal mangroves. Furtive and hard to see as it skulks in dense vegetation, such as tall grass and tangled forest understory. Varied vocalizations include clucks, churrs, squeaks, and extended rattles.
Speckled Mousebird
Colius striatus
A geographically-variable, dumpy-bodied, brownish-gray bird with a long, scruffy tail. Differentiated from other mousebirds by its blackish face and gray-brown crest. It is often found scrambling through bushes and tangles, creeping around on short legs. In flight, it flutters rapidly, and its tail seems to drag it down, as if it were too heavy to make it to the next bush. Occurs in small, sociable groups in forest edge, savanna, thickets in grassland, and gardens, feeding on fruit, leaves, flowers, and nectar. After eating, birds may hang upside-down and expose the black skin on their bellies to absorb heat and aid digestion.
Junin Antpitta
Grallaria obscura
Medium-sized, plain antpitta found in a limited area of the eastern Andes in south central Peru. It is uniform brown lacking strong field marks, but the pale eyering helps separate it from the similar Oxapampa Antpitta. Range and voice are also very important for ID. Typical songs include a short “bit-burr” and a series of five or six grating whistles. Inhabits the understory of high elevation forest and is mostly terrestrial, but sometimes perches higher to sing. It was formerly considered a subspecies of what used to be called Rufous Antpitta.
