Jet Manakin

Plump chickenlike bird found in rocky tundra and alpine summits. Plumage changes strikingly throughout the year. In winter, both sexes are pure white with black outer tail feathers. As summer progresses, male develops cold grayish-brown feathers on head, neck, and back; generally quite splotchy looking. Summer female is paler golden-brown with intricate black and white markings. Female nearly identical to Willow Ptarmigan; look for slightly smaller bill. Summer male Willow and Rock Ptarmigans can be separated by the colder grayish plumage on Rock Ptarmigan and in winter by the distinctive black eyeline on Rock Ptarmigan. Also note habitat differences. Best distinguished from White-tailed Ptarmigan by black outer tail feathers. Vocalizations include guttural groaning and clucking notes.

An acrobatic, swift-like raptor with angular wings and a massive gape; capable of snatching prey from the air and devouring it in a flash while still on the wing. Dark with varying amounts of white on the underside; African birds have patchy white throughout the underparts, while white is restricted to the throat and lower belly on New Guinean birds and solely to the throat in Southeast Asian birds. Inactive during the day; hunts at dawn and dusk, and occasionally into the night if light is sufficient. Generally uncommon and localized, most reliably encountered near large bat roosts in forested areas, but can also be seen over open forest, fields, and fringes of habitation.

Massive pale brown owl with plump, rounded ear tufts. An endangered species, found in mature boreal forests near streams where there are tree cavities suitable for nesting. Preys mostly on fish. Distinguished from Eurasian Eagle-Owl by absence of broad black streaks on breast and rounder, thicker ear tufts that are not held erect. Deep, resonant song, given in duet by pair. Duet consists of three notes, with the first two notes from a male and a third from a female. The lower-pitched female note partially overlaps with the second male note.
