Barred Tinamou
Crypturellus casiquiare
Very rare and poorly known tinamou of remote lowland rainforest. Existing records suggest that it favors areas with sandy soil. Rather small for a tinamou, with a chestnut head, a black back, wings marked with rusty bars, dingy underparts, and a pale throat. Few birders have ever seen it, and even hearing one requires some luck. Song is a series of whistles that starts out by accelerating and rising slightly in pitch, then slows down and falls towards the end.
识别特征
The barred tinamou is approximately 25 cm (9.8 in) in length. It is yellowish-buff with heavy bars of black on its back, its throat is white, its front and sides of neck and breast are pale grey, its belly is white, its flanks are cream barred with black, and its head and neck are chestnut in color with legs that are olive-green. The female is paler on back.[citation needed]
分类信息
This is a monotypic species. All tinamou are from the family Tinamidae, and in the larger scheme are also ratites. Unlike other ratites, tinamous can fly, although in general, they are not strong fliers. All ratites evolved from prehistoric flying birds, and tinamous are the closest living relative of these birds.

行为
Like other tinamous, the barred tinamou eats fruit off the ground or low-lying bushes. They also eat small amounts of invertebrates, flower buds, tender leaves, seeds, and roots. The male incubates the eggs which may come from as many as 4 different females, and then will raise them until they are ready to be on their own, usually 2–3 weeks. The nest is located on the ground in dense brush or between raised root buttresses.
保护状况
The IUCN classifies the barred tinamou as Least Concern, with an occurrence range of 49,000 km2 (19,000 sq mi).

Yellow-necked Spurfowl
Pternistis leucoscepus
A large brown francolin with yellow bare skin on the throat and red bare skin around the eyes. The bill and legs are black. Pale patches in the outer wings are conspicuous in flight. Found in a variety of fairly arid savanna habitats and in adjacent agricultural fields. Usually in pairs or small groups. Easily separated from other francolins by its bare yellow throat. The call is a fading series of rough “kreaaak” notes.
Timor Cuckoo-Dove
Macropygia magna
A large, long-necked, long-tailed dove with a dark rufous-brown back, wings, and tail that are extensively barred. Paler rufous on the head and buffier below, with extensive barring in male birds, though female and juvenile birds are only faintly barred or lack barring below. Singles, pairs, and groups occur within canopy of forest and forest edge in the lowlands and foothills. Unlike Little Cuckoo-Dove, the larger Timor Cuckoo-Dove shows noticeable barring above (and below in males). Gives a short, three-note burry call, rising at first, then falling on last notes: “whoOP-woo-hoo.”
Lark Sparrow
Chondestes grammacus
Large and boldly patterned sparrow. Look for unique black, white, and rufous face pattern, brighter on adults and duller on immatures. Favors open areas with scattered trees when breeding; often forms flocks in brushy areas in winter. Usually feeds on the ground and flies up into trees when disturbed. In flight, notice long tail with broad white corners.
