Cobalt-winged Parakeet
Brotogeris cyanoptera
Small green parakeet with a short tail. Blue wing feathers are hard to see when perched but are conspicuous in flight. Found in a variety of forested habitats, including around forest edges, gardens, and agricultural areas, often traveling in loud groups. Distinguished from similar Tui Parakeet by dark eye, green forehead, and peach chin, and from parrotlets by its larger size.
识别特征
The cobalt-winged parakeet is 18 to 20 cm (7.1 to 7.9 in) long and weighs an average of 67 g (2.4 oz). The species is almost entirely green that is darker on its upperparts. Adults of the nominate subspecies B. c. cyanoptera have a yellowish forehead, an orange chin, and a blue tinge on their crown and nape. Their flight feathers are blue; their central tail feathers are also blue and the rest are green. Immature birds are a duller version of the adult. Subspecies B. c. gustavi has very little blue on its head and a yellow edge on the carpals. B. c. beniensis is paler than the nominate with a similar amount of blue on its head and a yellow carpal edge like gustavi.
分类信息
The International Ornithological Committee and the Clements taxonomy attribute the first description of the cobalt-winged parakeet to August von Pelzeln, dated 1870. Pelzeln called it Sittace cyanoptera and separated it from what is now the orange-chinned parakeet (Brotogeris jugularis). Peters, in his Check-list of Birds of the World, cited Tommaso Salvadori (1891) as the originator, and this citation is used by BirdLife International's Handbook of the Birds of the World.<p>The cobalt-winged parakeet has these three subspecies:<p>Subspecies B. c. gustavi has been treated as a separate species by some authors. The cobalt-winged and golden-winged parakeet (B. chrysoptera) are sister species.

分布与栖息地
The subspecies of the cobalt-winged parakeet are found thus:<p>The cobalt-winged parakeet inhabits a variety of landscapes including the edges and interior of rainforest, secondary forest, várzea , savanna, and Llanos. In elevation it commonly reaches 1,000 m (3,300 ft) and occasionally 1,350 m (4,400 ft).

行为
The cobalt-winged parakeet is thought to be mostly sedentary but might make some seasonal elevational movements.<p>Little is known about the cobalt-winged parakeet's foraging technique and diet. It has been recorded feeding on flowers, fruits, and Cecropia catkins. It also eats mineral-impregnated soil.<p>The cobalt-winged parakeet's breeding season is not well known but apparently includes June and July in the western part of its range. It nests in tree cavities. Captive pairs lay clutches of about five eggs that hatch in 24 days.<p>The cobalt-winged parakeet's common calls are " a high-pitched “klee”, shrill “chree” or bisyllabic “chree-chree”" that are given both when perched and in flight. Another call is "a fast chattering series “chichichichichi”." Members of flocks call simultaneously and make "a shrill chattering".

Atlas Wheatear
Oenanthe seebohmi
Small thrush-like bird with distinctive black-and-white tail pattern that is striking in flight. Breeding male has a black face, throat and wing, gray back and crown, and white underparts. Breeding female is duller, with a brownish crown and back, and usually a speckled blackish face and throat. Nonbreeding and immature birds are duller overall, though males retain their distinctive black throat. Breeds in the Atlas Mountains of northwest Africa, in areas of bare rock and short grass. Migrates south into the Sahel, where it spends the non-breeding season in a variety of open habitats such as grasslands and barren rocky plains. Tends to stay on the ground or on low perches. Jumbled-sounding song is quite variable, often including whistles, trills, and mimicry. Similar in appearance to Northern Wheatear, though male Atlas Wheatear is usually separated by its black throat. Separating females during migration and on the wintering grounds is usually difficult. Female Atlas Wheatear has a black “wingpit” and front part of the underwing, but this is hard to see in the field.
Black-headed Saltator
Saltator atriceps
Fairly common in humid tropical lowlands. Favors forest edge, plantations, adjacent semi-open areas with trees and hedges. Usually in noisy small groups moving at mid-upper levels. Black head and bib surrounds white throat patch (throat patch buffy in Los Tuxtlas region of southern Veracruz), upperparts bright golden green. Larger and noisier than the rather similar Buff-throated Saltator, which has a less contrasting black head.
Black-legged Seriema
Chunga burmeisteri
Tall terrestrial predator of the Chaco region. Plumage distinctively shaggy. Prefers dense, spiny vegetation, often with thick undergrowth, but can occur in nearby open areas. Smaller and shyer than Red-legged Seriema. Despite its large size, can be difficult to see, and is more often detected by its loud, far-carrying song.
