most are drab, with uniform olive-brown to black plumage. Some species have distinct crests. Leaf warblers Order: PasseriformesFamily: Phylloscopidae Leaf warblers are a family of small insectivorous birds found mostly in Eurasia and ranging into Wallacea and Africa. The species are of various sizes, often green-plumaged above and yellow below, or more subdued with greyish-green to greyish-brown colours. Sylviid warblers, parrotbills, and allies Order: PasseriformesFamily: Sylviidae The family Sylviidae ("Old World warblers") is a group of small insectivorous passerine birds. They mainly occur as breeding species, as one common name implies, in Europe, Asia, and, to a lesser extent, Africa. Most are of generally undistinguished appearance, but many have distinctive songs. White-eyes, yuhinas, and allies Order: PasseriformesFamily: Zosteropidae The white-eyes are small and mostly undistinguished, their plumage above being generally some dull colour like greenish-olive, but some species have a white or bright yellow throat, breast, or lower parts, and several have buff flanks. As their name suggests, many species have a white ring around each eye. Laughingthrushes and allies Order: PasseriformesFamily: Leiothrichidae The members of this family are diverse in size and colouration, though those of genus Turdoides tend to be brown or greyish. The family is found in Africa, India, and southeast Asia. Treecreepers Order: PasseriformesFamily: Certhiidae Treecreepers are small woodland birds, brown above and white below. They have thin pointed down-curved bills which they use to extricate insects from bark. They have stiff tail feathers, like woodpeckers, which they use to support themselves on vertical trees. Oxpeckers Order: PasseriformesFamily: Buphagidae As both the English and scientific names of these birds imply, they feed on ectoparasites, primarily ticks, found on large mammals. Starlings Order: PasseriformesFamily: Sturnidae Starlings are small to medium-sized passerine birds. Their flight is strong and direct and they are very gregarious. Their preferred habitat is fairly open country. They eat insects and fruit. Plumage is typically dark with a metallic sheen. Thrushes and allies Order: PasseriformesFamily: Turdidae The thrushes are a group of passerine birds that occur mainly in the Old World. They are plump, soft plumaged, small to medium-sized insectivores or sometimes omnivores, often feeding on the ground. Many have attractive songs. Old World flycatchers Order: PasseriformesFamily: Muscicapidae Old World flycatchers are a large group of small passerine birds native to the Old World. They are mainly small arboreal insectivores. The appearance of these birds is highly varied, but they mostly have weak songs
