Burnished-buff Tanager
Stilpnia cayana
A common tanager of savannas, forest borders, woodlands, and gardens. Often seen in pairs or with other species at fruiting trees, but usually not with mixed-species flocks. Males have a black face, throat, breast, and belly that is flanked by buffy sides. The crown and back are also buff and the wings and tail are dark-green. Females are buffy below with greenish back and wings, a pale throat, and a faint mask. The northern subspecies has a black mask (lacking the black throat and belly) with a violet gray throat and buffy belly.
识别特征
There are several subspecies of the burnished-buff tanager, them falling into two main groups: The northern and western cayana group, and the southern and eastern flava group (the subspecies huberi from Marajó Island is intermediate between the two main groups). Males of the cayana group have an orange-rufous crown, black mask, and cream underparts distinctly tinged blue on the throat and chest. Males of the flava group have an orange-buff crown, and buff underparts with a black patch extending from the mask, over the throat and central chest, to the mid-belly. Males of both groups have turquoise wings and tail. Females are duller than the males, and have black restricted to a poorly demarcated "shadow" of a mask.
分类信息
The burnished-buff tanager was formally described in 1766 by the Swedish naturalist Carl Linnaeus in the 12th edition of his Systema Naturae under the binomial name Tanagra cayana. The specific epithet is the Latin form of the type locality, Cayenne in French Guiana. The burnished-buff tanager was formerly placed in the genus Tangara. It was moved to the genus Stilpnia that was introduced in 2016.<p>Seven subspecies are recognised:

分布与栖息地
It is found in the northern Guianas, most of Venezuela and east-central Colombia; also near the Amazon River outlet in Brazil, as well as most of the east of that country, Paraguay and northeast Argentina. It also occurs very locally in Bolivia and Peru. It can be seen in virtually any semi-open habitat with trees, including human-altered habitats such as gardens, plantations and parks.

White-backed Vulture
Gyps africanus
A large, buff-brown vulture with pale underwing patches and a diagnostic pale rump patch that is best seen in flight. Prefers open savanna and plains, where it breeds in loose colonies in tall trees. It remains Africa’s commonest vulture but is declining rapidly as it is highly susceptible to poisoning. The similar Cape Griffon is larger and paler, with a pale honey-colored eye (visible at close range), and less contrast between the flight feathers and the reminder of the underwing in flight.
Ridgway's Rail
Rallus obsoletus
Large, chickenlike rail of mangroves and fresh marshes in lowlands. Heard more often than seen; its main call is a rhythmic dry chatter. No similar large rails in its range. Note the large size, rusty neck and breast, barred flanks, and long, mostly orange beak. Virginia Rail is much smaller, with blue-gray cheeks.
Black-browed Albatross
Thalassarche melanophris
A common and widespread albatross of the southern oceans; often seen from shore and ferries. Like other albatrosses, often scavenges at fishing boats. All plumages white-headed, often obvious at long distance (black brow only visible at close range). Adult has orange-yellow bill, brighter at the tip and thick black irregular underwing margins; 1st-year has dusky bill with black tip and solidly blackish underwings; mostly like adult in 3 years.
