Golden-capped Parakeet
Aratinga auricapillus
Medium-sized parakeet with a long graduated tail. Usually seen in noisy groups in light woodland, savanna, farmland, and even urban areas. The body is mostly green and contrasts with its black bill, yellow crown, red forehead, and reddish belly patch. It has blue flight feathers, but in flight note the prominent orange underwings.
识别特征
It is 30 cm (12 in) long and mostly green with a black beak, white eyerings, orange-red belly, and red face fading to yellow over the crown. Juvenile members of the A. auricapillus group develop their yellow head markings and red coloration on the lower body in adulthood. The approximate weight for golden-capped parakeets is 4.9-5.25 oz.
分类信息
The Aratinga genus name was created to describe medium to small south American conures and parrots. As such, alongside its common name as the golden-capped parakeet, it is also called the golden-capped conure. Within the A. solstitialis species group, the golden-capped parakeet is the only member considered to be polytypic: A. auricapillus is said to contain the subspecies A. a. aurifrons. The measured variable for this basis is slightly varied coloration between the two (less red on back and yellow on head for A. a. aurifrons than that of A. auricapillus). Other variables such as size were found to have little variability between the two, and thus the distinction is still under question.

分布与栖息地
The Aratinga auricapillus inhabits mostly the semi-deciduous forests in northeastern Brazil, although through time it has adapted to rural agricultural areas and sometimes even urban cities, spreading throughout the states of Bahia, Minas Gerais, Espírito Santo, Rio de Janeiro, São Paolo, Goiás, and Paraná.

行为
As members of the Aratinga solstitialis subspecies, golden-capped parakeets tend to populate their areas of residence within forests in groups, which can range from 4 to 15 individual parakeets. The breeding season occurs during the austral summer, which in the southern hemisphere is from December to March, with pairs being sighted around November and dependent young around March. Golden-capped parakeets have a clutch size of around 3 to 5 eggs per nesting; the incubation period for these eggs is estimated to be around 25 days, and young fledglings take around 7–8 weeks before they are able to take flight.

Rock Pipit
Anthus petrosus
Plumage relatively dull and dark: grayish brown to grayish above with weak darker streaking; dingy whitish below with heavy and rather blurry dark streaking. Also note the dark legs (pink on smaller and buffier Meadow Pipit, which often occurs in coastal grassland adjacent to Rock Pipits). Song is a bland, repetitive, high-pitched series, often accelerating towards the end. Call a high, lisping, slightly harsh "ssiip", very similar to that of Water Pipit. Like other pipits, walks strongly and often pumps its tail a little. Found along rocky coasts; infrequent inland. Often seen on rocks and adjacent areas with short grass.
Rufous-backed Antvireo
Dysithamnus xanthopterus
Big headed antbird with a heavy hooked bill and a shortish tail. Rufous above and pale below with a gray neck and face dappled with white spots. Males have a dark gray cap, rufous in females. The song is a loud and fast descending series of trembling notes. Found in the upper to middle levels of humid forests, usually with mixed-species flocks.
Dark Pewee
Contopus lugubris
The only all-dark crested flycatcher in range. Entirely sooty-gray, only slightly paler on throat and belly. More obvious crest than other pewees. Sexes alike. Usually seen singly, perched conspicuously at the forest edge or in a clearing. Listen for “pip” call notes.
