The little brown bustard (Heterotetrax humilis) is a species of bird in the family Otididae. Found in Ethiopia and Somalia, its natural habitats are subtropical or tropical dry shrubland and subtropical or tropical dry lowland grassland. As indicated by its name, this bustard is the world's smallest at 45 cm (18 in) and 600 grams (1.3 lb). It is threatened by habitat destruction.

Description

The smallest species in its genus, the little brown bustard reaches a maximum length of about 45 cm (18 in). They are light brown birds with whitish underparts. The male has a black tuft on the nape, and a black throat speckled with white. The female lacks these black areas, instead having heavy buff spotting on the back, wings and breast. Both male and female have dark flight feathers on the wings, and when flying show a slender white wing-bar, which divides the black feathers from the sandy-brown wing coverts. [3] The female white-bellied bustard (Eupodotis senegalensis), which has a wider range, is larger and darker and has bluish-grey colouring on the back of the neck. The call of the little brown bustard is uttered with the neck outstretched and the head thrown back and is a high-pitched, rattling sound. [3]

Distribution and habitat

The little brown bustard is endemic to the Horn of Africa, where its range includes southern and eastern Ethiopia and northern and central Somalia. [3] Its typical habitat is dry scrub and open thornbush, and it sometimes moves out onto tussocky plains. It occurs at altitudes of up to 1,500 m (5,000 ft). [3]

Ecology

Bustards are ground dwelling birds, walking briskly on sturdy legs, foraging as they go. They are able to fly but seem to prefer running and walking. [4] The diet of the little brown bustard consists of seeds, buds, insects and small vertebrates such as lizards. The breeding season is from April to August; two eggs (occasionally three) are laid on the ground and incubated by the female. [1] [4]

Status

The total population of this bird is unknown, but its range coincides with an area where war was being waged in the 1970s and 1980s when there was a marked decline in its population. [1] There have also been droughts in the area and disturbances caused by the establishment of refugee camps, hunting, cultivation, and the gathering of firewood so it is likely that some local populations have been eliminated. Although still fairly common in some areas, the general population trend is downwards, and the International Union for Conservation of Nature has assessed the bird's conservation status as "near threatened".

The great Indian bustard or Indian bustard, is a bustard found on the Indian subcontinent, or in Rajasthan, in the Thar Desert. A large bird with a horizontal body and long bare legs, giving it an ostrich like appearance, this bird is among the heaviest of the flying birds. Once common on the dry plains of the Indian subcontinent, as few as 150 individuals were estimated to survive in 2018 and the species is critically endangered by hunting and loss of its habitat, which consists of large expanses of dry grassland and scrub. These birds are often found associated in the same habitat as blackbuck. It is protected under the Wild life Protection Act, 1972 of the Parliament of India.

<span class="mw-page-title-main">Lesser florican</span> Species of bird

The lesser florican, also known as the likh or kharmore, is the smallest in the bustard family and the only member of the genus Sypheotides. It is endemic to the Indian Subcontinent where it is found in tall grasslands and is best known for the leaping breeding displays made by the males during the monsoon season. The male has a contrasting black and white breeding plumage and distinctive elongated head feathers that extend behind the neck. These bustards are found mainly in northwestern and central India during the summer but are found more widely distributed across India in winter. The species is highly endangered and has been extirpated in some parts of its range such as Pakistan. It is threatened both by hunting and habitat degradation. The only similar species is the Bengal florican which is larger and lacks the white throat, collar and elongated plumes.

The Australian bustard is a large ground-dwelling bird that is common in grassland, woodland and open agricultural country across northern Australia and southern New Guinea. It stands at about one metre high, and its wingspan is around twice that length. The species is nomadic, flying to areas when food becomes plentiful, and capable of travelling long distances. They were once widespread and common to the open plains of Australia, but became rare in regions that were populated by Europeans during the colonisation of Australia. The bustard is omnivorous, mostly consuming the fruit or seed of plants, but also eating invertebrates such as crickets, grasshoppers, smaller mammals, birds and reptiles.
