Long-tailed Manakin
Chiroxiphia linearis
Attractive, chunky little bird of tropical forest in dry and humid lowlands and foothills. Away from display areas, usually found in ones and twos perched quietly or feeding at fruiting trees and bushes from understory to canopy. Complex displays involve loud whistles and interactions between two males. Adult male is unmistakable. Female and young are greenish overall with orange legs and rather long tail. Immature males have varying degrees of adult male plumage; the sky-blue back being the last feature to appear.
识别特征
Large for a manakin, the long-tailed measures about 10 cm (3.9 in) long and weighs 18 g (0.63 oz).<p>The male is mostly a rich black. This is contrasted by a bright red crown and legs. The back is bright blue. The two central tail feathers are narrow and greatly elongated. The female is olive green, paler below and on the chin and throat. Some females have a small amount of red in the crown.<p>It closely resembles the lance-tailed manakin (C. lanceolata), the blue-backed manakin (C. pareola), the swallow-tailed manakin (C. caudata), and the Yungas manakin (C. boliviana), which all have the same red crown and blue back. There is, however, no overlap in range with these four species.

行为
The manakin species are very interesting in their family life. Long-tailed manakin males form a long-term partnership duo or trio. Together they sing in synchrony and, for any female who is attracted by their singing, perform a complex coordinated courtship dance. If she mates, only the alpha male inseminates her. Among many displaying male partnerships in a locality (a dispersed lek), only one or a very few males may account for the vast majority of matings in a given breeding season. As in other lekking species, the female then builds the nest and raises the young without involvement by males.

Eurasian Jackdaw
Coloeus monedula
Distinctive, small social crow with contrasting, silvery-gray neck shawl and staring whitish eyes; juvenile has duller shawl and eyes. Walks confidently, and can be easy to see where not persecuted; associates readily with crows and Rooks. Flocks can number in the hundreds or thousands in the nonbreeding season. Inhabits open and semiopen habitats, from towns and wooded parkland to farmland and sea cliffs; often around stone buildings and chimneys. Nests in cavities. Listen for its distinctive high-pitched “tchaw, tchaw” calls.
Bismarck Crow
Corvus insularis
A medium-sized entirely black crow with a large, often pale-tipped bill and a pale bluish eye. Common in most open forest and forest-edge habitats. Often seen around towns. Voice consists of short, nasal cawing notes.
Black Tinamou
Tinamus osgoodi
Large, rare tinamou found in cloud forest along the east slope of the Andes. It is uniformly sooty gray, much darker and plainer than Gray Tinamou. Rusty lower underparts are hard to see in the field. Like other forest tinamous, it is far more likely to be heard than seen. Vocalizations include a low, drawn out coo, like a dove’s but longer, and a series of low, modulated whistles.
