Purple-throated Fruitcrow
Querula purpurata
Large, mostly black bird found in the canopy of lowland forests. Male has wine-colored throat that can be puffed out expressively, but is often difficult to see in poor light. The overall dark color, stout silvery bill, and chunky proportions help identify this bird even at a distance. Also listen for the distinctive purring whistles, “prr-woop, prr-woop.” Typically found in small vocal groups that parade through the canopy, sometimes following mixed-species flocks. Compare with umbrellabirds, which are larger, have a puffy crest, and are much less vocal.
识别特征
It is a stout medium-sized glossy-black bird. Males have a large purple-red upper throat patch, (similar to the gorget of the hummingbirds), extending to the side of the neck. It has a short wide pointed grayish bill, black eyes, and gray legs.

分布与栖息地
It is found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela; also in southern Central America in Nicaragua, Costa Rica and Panama. Its natural habitat is subtropical or tropical moist lowland forests.<p>The purple-throated fruitcrow ranges across northern South America, with populations west of the Andes cordillera extending into Central America to Nicaragua. It goes from the Guianas and Maranhão state, northeastern Brazil in the east, and throughout the Amazon basin to the Andes foothills in the west; it is only absent in the Amazon Basin in the northeast and north central bordering the Guiana Highlands and southern Venezuela; otherwise the range is contiguous east of the Andes. Its population trend is thought to be downwards but it is a common species with a very wide range and the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".

行为
Despite its name, the purple-throated fruitcrow feeds on insects as well as fruit, moving through the forest canopy in small chattering groups. It also nests colonially, with little attempt to hide the nests which are rendered more conspicuous by the noisy group of birds nearby.

Long-tailed Honey-buzzard
Henicopernis longicauda
A large, long-tailed raptor of lowland and montane forest and clearings. Commonly seen in flight soaring in circles over the canopy with wing and tail feathers spread, showing strong barring. The only similar looking raptor that regularly soars is Pacific Baza, but Long-tailed Honey-buzzard has a streaked chest and lacks the buffy underwing and belly. When perched, similar to Doria’s Goshawk, but has yellow eyes and white legs. Usually silent.
Scarlet-browed Tanager
Heterospingus xanthopygius
Distinctive tanager found in lowlands and foothills from eastern Panama to northwest Ecuador. Male is black with a bold red stripe behind the eye, a white patch on the side of the breast, and a yellow shoulder and rump that are difficult to see, especially on perched birds. Females are gray overall instead of black and lacks the red eye stripe, but does show white patch on the side of the breast. Pairs or small groups are found in the canopy of forest, edges, and second growth, sometimes perching quite conspicuously. Often follows mixed-species flocks.
Dusky Nightjar
Antrostomus saturatus
Small dark nightjar with very limited range in the highlands of Costa Rica and Panama. Few obvious plumage features: entire body is intricately patterned with dark brown, black, and buff. Pale corners to tail (white in male, buffy in female). Fairly common above around 1,500 m, where it can be found at the edge of cloud forest. Usually perches on a fence post or low branch. Strictly nocturnal, and easily detected by voice; listen for the trilled “whip, wee-per-wee!,” rising at the end. Closely related to whip-poor-wills further north.
