Brushland Tinamou
Nothoprocta cinerascens
Small, short-necked tinamou of the chaco region of the central Southern Cone. Most often detected by voice. From similar White-bellied Nothura, with which its range partly overlaps, by gray legs and brownish belly. Tends to prefer thorn forest with dense grass or scrubby understory, but can be seen along road sides. Song a 5-8 part flat whistle, given with progressively more emphasis.
识别特征
The brushland tinamou is approximately 31.5 cm (12.4 in) in length and weighs 540 g (1.19 lb). Its upper parts are grey to olive-brown barred with black and prominently streaked with white. Its crown is black, the sides of its head and its throat are white, its lower throat is barred black, its breast is grey spotted with white, and its belly is whitish. Its legs are dark grey. The female is larger and darker.
分类信息
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.<p>Hermann Burmeister first identified the brushland tinamou from a specimen from Tucumán Province, Argentina, in 1860.<p>A phylogenetic study published in 2022 found that the brushland tinamou was more closely related to species placed in the genus Rhynchotus than it was to the other members of the genus Nothoprocta.<p>The brushland tinamou has two subspecies as follows:

分布与栖息地
The brushland tinamou prefers to live in dry shrubland up to 1,000 m (3,300 ft) in altitude. But it can regularly be found as high as 2,000 m (6,600 ft), and also in dry savanna, dry grassland, or grassland that is seasonally flooded, and also pastureland and farmland. This species is native to southeastern Bolivia, northwestern Paraguay and northwestern and central Argentina in South America.

行为
The call of the brushland tinamou is a series of seven to ten clear whistled notes that carry, and will be hard as they defend their range of about 50 acres (20 ha). They feed off of insects and small animals and some fruit.<p>Males attract two to four females and supervise their laying of eggs in the nest, which is typically hidden in brush. Females will leave to find other males and the male will incubate the eggs and raise the chicks.
保护状况
The brushland tinamou is classified by the IUCN as Least Concern, with an occurrence range of 1,200,000 km2 (460,000 sq mi).

Halmahera Golden-Bulbul
Hypsipetes chloris
A thrush-sized bird with a fairly long horn-colored bill. Uniform rich olive-green above and all yellow underneath, with dark eyes. Juveniles duller and pale-eyed. Typically found in pairs or small groups in primary and degraded forest, plantations, and mangroves, in lowlands and lower hills. Confined to a cluster of islands in the North Moluccas where there are no other bulbuls or similar species. Loud, jumbled, characteristic bulbul-like-song consists of repeated “chidlydu-chidlydu-chidlydu” phrases. Also gives thin, high-pitched insect-like “tsee” notes and rasping “weerrrr” calls.
Band-tailed Fruiteater
Pipreola intermedia
Chunky green bird with coral red bill and legs. Males have a black hood, a yellow collar, and a green body with a scaled pattern underneath; females are entirely green with a similar scaly belly pattern, and typically a complete yellow eye-ring. Found singly or in pairs in montane forest. Similar but slightly larger than Green-and-black Fruiteater, which lacks the black terminal tail band and white tail tips of Band-tailed. Male Band-taileds are also typically more heavily patterned underneath than that species, and females have a more prominent eye-ring.
Masked Tityra
Tityra semifasciata
Handsome, mostly silvery gray bird of tropical and subtropical forest and adjacent semi-open areas with taller trees. Usually found at mid-upper levels of fruiting trees, sometimes in small groups. Identified readily by pinkish base to bill and pinkish ‘mask’ around eyes. Females in most areas have a dark brownish head, but in West Mexico the females have a pale gray head and back. Distinctive call is a wet quacking or farting sound.
