Pied Barbet
Tricholaema leucomelas
A medium-sized barbet with uniformly white underparts, a black throat patch, a red forehead, and a striking yellow-and-white eyebrow. Pairs reside in semi-desert, savanna, and gardens, preferring thickets and more treed areas with suitable for nest cavities. Calls a distinctive melancholy “poooop” 6–7 times, often accompanied with a nasal, repeated “nyeeeeaar”. Miombo Barbet differs by lacking the dark throat patch and by having heavily-spotted underparts and a yellowish breast. The two species hybridize in southern Zambia.
识别特征
The acacia pied barbet has dark brown eyes and blackish legs and feet. It has a black-and-white striped head with a red front and forecrown and pale yellow superciliary stripe. It has a black bib under the chin, with a white breast and underparts in the drier land subspecies T. l. centralis. The breast and underparts are more dusky and streaky in the southerly nominate subspecies, and more yellowish in the easterly T. l. affinis. The sexes are similar in appearance. Juvenile birds lack the red mark on the forehead, and have the underpart plumage more streaky.
分类信息
The acacia pied barbet was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1780 in his Histoire Naturelle des Oiseaux from a specimen collected from the Cape of Good Hope region of South Africa. The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Neither the plate caption nor Buffon's description included a scientific name but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Bucco leucomelas in his catalogue of the Planches Enluminées. The acacia pied barbet is now placed in the genus Tricholaema that was introduced by the French brothers Jules and Édouard Verreaux in 1855. The generic name combines the Ancient Greek thrix meaning hair and laimos meaning "throat". The specific leucomelas combines the Ancient Greek leukos meaning "white" and melas meaning "black".<p>Three subspecies are recognised:

分布与栖息地
It primarily inhabits semi-arid savanna, as well as grassland, fynbos, agricultural areas and urban gardens, which it did not inhabit formerly. With the introduction of alien vegetation, especially Racosperma species from Australia, to regions bordering its original range, this species has been able to expand its range to these otherwise unreachable areas.<p>It is found in Angola, Botswana, eastern Eswatini, western Lesotho, southern Mozambique, Namibia, South Africa, southern Zambia, and Zimbabwe.

行为
The acacia pied barbet is a sedentary but fairly restless species that occurs in pairs or singly. Its flight is fast and direct. The acacia pied barbet drills holes into dead wood to create cavity nests, like most other barbets and woodpeckers. It lays two to four eggs from August to April, and both sexes incubate the eggs.<p>The acacia pied barbet has been observed taking fruit from various trees and shrubs, such as Ficus, Searsia and Phoenix reclinata, as well as Aloe nectar and insects.

Afghan Babbler
Argya huttoni
Slender, dusty-colored babbler with a long tail. Look for its contrasting white throat and streaked crown and back. Found in dry open areas such as semidesert, scrubland, and various edge habitats. Rummages about on the ground in mid-sized to large flocks. Gives a clear, musical, purring series of notes, either ascending or descending, as well as harsher, scratchier calls.
Common Gull
Larus canus
Small dainty gull. Dark-eyed and long-winged with a rounded head. Breeding adults are white-headed with a variable smudgy ring on the bill; non-breeding adults have light brown markings on the head. Younger birds are brownish, with black-tipped pink bills. Occurs throughout much of Eurasia. Breeds in wetlands, meadows, and beaches; winters in waterside habitats and fields, especially near the coast. Does not frequent large urban centers as much as some other gulls.
Western Rosella
Platycercus icterotis
Red-and-green rosella with a yellow cheek in adults. The only rosella found in southwestern Western Australia, where it inhabits open woodland habitats and parks, usually feeding on the ground. Adult mottled green and black (or red) above, with red underparts and crown, blue rump, and blue wings. Adult male has more intense colors than female; juvenile lacks yellow cheeks and is more extensively green. Two subspecies exist, varying in back color: the inland subspecies has a green-and-black back, the southwestern subspecies a red-and-black back. Call is a slow, ringing double note; also gives chattering calls.
