The Old World babblers or timaliids are a large family of mostly Old World passerine birds. They are rather diverse in size and coloration, but are characterised by soft fluffy plumage. These are birds of tropical areas, with the greatest variety in Southeast Asia and the Indian subcontinent. The timaliids are one of two unrelated groups of birds known as babblers, the other being the Australasian babblers of the family Pomatostomidae (also known as pseudo-babblers). Morphological diversity is rather high; most species resemble "warblers", jays or thrushes. This group is among those Old World bird families with the highest number of species still being discovered. ==Characteristics== Timaliids are small to medium birds. They have strong legs, and many are quite terrestrial. They typically have generalised bills, similar to those of a thrush or warbler, except for the scimitar babblers which, as their name implies, have strongly decurved bills. Most have predominantly brown plumage, with minimal difference between the sexes, but many more brightly coloured species also exist. This group is not strongly migratory, and most species have short rounded wings, and a weak flight. They live in lightly wooded or scrubland environments, ranging from swamp to near-desert. They are primarily insectivorous, although many will also take berries, and the larger species will even eat small lizards and other vertebrates.〔 Typical babblers live in communities of around a dozen birds, jointly defending a territory. Many even breed communally, with a dominant pair building a nest, and the remainder helping to defend and rear their young. Young males remain with the group, while females move away to find a new group, and thus avoid inbreeding. They make nests from twigs, and hide them in dense vegetation.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Old World babbler」の詳細全文を読む スポンサード リンク
