Indian Vulture
Gyps indicus
A light brown, medium-sized vulture. It has whitish feathers on a dark head and neck, a pale bill, and a pale collar which is more prominent behind the neck. The juvenile has a dark bill, more white feathering on the head and neck, and browner plumage overall, with pale streaks on breast and belly. In flight, note the pale underparts and underwing contrasting with the dark flight feathers. The species nests in colonies on cliffs and ruins, and occasionally in trees. Similar to Slender-billed Vulture, but Indian Vultures are not as lanky and have a paler bill and very tiny ear holes.
识别特征
The Indian vulture is bulky and medium in size. Its body and covert feathers are pale brown with darker flight feathers. It has white thighs with scattered white fluff and broad wings with short tail feathers. It has a small, bare, dark-brown head with a long featherless neck, dark eyes and a long yellowish beak with a pale green-yellow cere. It is 89–103 cm (35–41 in) long and has a wing span of 2.22–2.58 m (7 ft 3 in – 8 ft 6 in). <p>The bald heads allow them to maintain body temperature in response to the environment. When it is cold, they tuck their necks in closer to their bodies to keep them warm and when it is hot, they extend their necks. Indian vultures have very few feathers on their heads which help them to keep their heads clean when they stick them into the rotting carcasses to feed. <p>It weighs 5.5–6.3 kg (12–14 lb) and is comparatively smaller than the Eurasian griffon. It is distinguished from that species by its less bulky body and wing coverts.
分类信息
The Indian vulture is placed in the genus Gyps (old world vultures), and gets both its common and specific scientific names from its nativity to the Indian subcontinent. The genus name is from Ancient Greek gups meaning "vulture" and the species name is Neo-Latin indicus from the Ancient Greek "indikós" meaning "Indian".<p>The slender-billed vulture (Gyps tenuirostris) was a sub-species of Indian vulture until 2001. Based on nuclear and mitochondrial DNA evidence, it was separated into a different species from the Indian vulture in 2001.

分布与栖息地
The range of the Indian vulture extended from southeastern Pakistan to south India and to Indochina and the northern Malay Peninsula in the east. It is now extinct in South East Asia with current populations existing mostly in central and peninsular India, south of the Gangetic plains. It is also found in southwest Pakistan, Bangladesh and Nepal.<p>It is also found in various land-forms ranging from semi-desert to dry foot hills, open fields and cultivable lands near villages, near garbage dumps and slaughter houses in urban areas. They are not migratory but travel hundreds of miles in a day scavenging for food. Indian vultures nest on cliffs or high buildings and rarely on trees.

Miombo Rock-Thrush
Monticola angolensis
Attractive rock-thrush in which males and females are strikingly different. Males have a gray head and back and rufous underparts, while females have a brown, heavily scalloped head and back and mostly white underparts. Found very locally in miombo broadleaf woodland. The song consists of musical, vibrating whistles. Similar to migratory Rufous-tailed Rock-Thrush, but male lacks white back and female has little or no scalloping below.
Red-collared Woodpecker
Picus rabieri
Distinctive olive-green woodpecker with a shawl-like red pattern on the head. Male is essentially red-headed except for a pale throat and a green ear patch, while female lacks the red crown and has less red on the nape. Body coloration similar to other green woodpeckers in range, but less streaked and overall quite dark underneath. Inhabits mixed forests from lowlands to foothills, and occasionally open and edge areas.
Sunset Lorikeet
Trichoglossus forsteni
A fairly large long-tailed parrot with unmistakable striking coloration. Green with a dark purple head, a red bill, a lime-green collar, and a broad red chest patch above deep purple underparts. Juveniles duller, with a brownish bill. Found in noisy groups, mainly in the lowlands but also up into the mountains, where it occupies the edges of forests and wooded areas. Restricted to Lombok and Bali, where it is the only lorikeet. Gives shrill screeches: “EEEEK!”
