White-bellied Nothura
Nothura boraquira
Small, sand-colored tinamou with a mix of rusty and dark spots on the back and a white belly. Found in natural and human-modified grasslands, where it is difficult to catch sight of due to its retiring nature and cryptic plumage. The song is a high, thin “peeea.”
识别特征
The white-bellied nothura is approximately 27 cm (11 in) in length. Its upper parts are light brown and barred black with white streaks. Its throat is white, its foreneck is buff with black streaking, its breast is buff and its belly is white. Its crown is dark brown and the sides of its head are buff. The legs are bright yellow and the inner webs of its primaries are uniformly dark, unlike in the closely related spotted nothura.
分类信息
The white-bellied nothura is a monotypic species. All tinamous 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.

分布与栖息地
The white-bellied nothura prefers dry shrubland regions up to 500 m (1,600 ft) in altitude. It can also be found in dry grassland, savanna, caatinga, and occasionally pastures. This species is native to northeastern and central Brazil, eastern Bolivia and Paraguay.

行为
Like other tinamous, the white-bellied nothura 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 this species as Least Concern, with an occurrence range of 1,400,000 km2 (540,000 sq mi).

Brown-headed Honeyeater
Melithreptus brevirostris
Small honeyeater with brown cap. Primarily gray-brown with olive back and lighter underparts. Eye patch and band leading from the eye to back of the head are cream-colored. Juveniles have pale blue coloration around the eye and a yellow bill. Take care to separate from juvenile White-naped Honeyeater, which lacks the pale half collar around the side of the neck. The plumage of this species varies geographically. Common in eucalypt forests, where it is usually very vocal and active. Forages in small groups.
Mountain Kingfisher
Syma megarhyncha
A large kingfisher of foothill and mid-montane forest. Bright orange head and body, blue back and tail, bright yellow bill and black mark on the back of the head. Females also have a black mark on the crown. Almost identical to Yellow-billed Kingfisher, but Mountain Kingfisher is larger, found higher up, and most birds have a dark smudge on top of the bill. Call, an accelerating series of loud notes, first rising slightly, then falling and ending in a trill. Remeniscent of a New World antshrike.
Green Malkoha
Ceuthmochares australis
Odd, dark, green-and-gray cuckoo with a bright yellow bill. Found in thick habitats including forest, forest edge, and thickets. Skulks in the thickest parts of the mid-story, especially preferring vine tangles. Call starts with a hesitant series of high “kik” notes, eventually followed by a long, accelerating trill. Dark coloration and yellow bill are distinctive. Range does not overlap with the similar Blue Malkoha.
