Warbler




 * Also the name of a singing group (Glee: The Music Presents the Warblers) in the TV show Glee.

There are a number of Passeriformes (perching birds) called "warblers". They are not particularly closely related, but share some characteristics, such as being fairly small, vocal and insectivorous.

They are mostly brownish or dull greenish in color. They tend to be more easily heard than seen. Identification can be difficult and may be made on the basis of song alone. To English-speaking Europeans, warblers are the archetypal "LBJs" (little brown jobs).

Sylvioid "warblers"
These are somewhat more closely related to each other than to other "warblers". They belong to a superfamily also containing Old World babblers, bulbuls, etc.
 * "Old World warblers", formerly all in family Sylviidae
 * Leaf-warblers, now in family Phylloscopidae
 * Typical bush-warblers, now in family Cettiidae
 * Grass-warblers and megalurid bush-warblers, now in family Locustellidae
 * Marsh- and tree warblers, now in family Acrocephalidae
 * True warblers or sylviid warblers, remaining in family Sylviidae or moved into Timaliidae
 * Malagasy warblers, the newly assembled family Bernieridae
 * Cisticolid warblers, family Cisticolidae
 * "African warblers", possibly another novel family

Passeroid "warblers"
The two families of American "warblers" are part of another superfamily, which unites them with sparrows, buntings, finches, etc.
 * Olive Warbler, monotypic family Peucedramidae
 * New World warblers, family Parulidae

Other
These are closely related to the titmice and chickadees
 * Tit-warblers or flycatcher-tits, family Stenostiridae

These are the most distinct group of "warblers". They are not closely related at all to the others, but rather to the honeyeaters and fairy-wrens.
 * Australasian warblers, family Acanthizidae


 * Hawaiian honeycreeper&mdash;Warbler-niched-(adaptive radiation), genus H. virens–Common Amakihi. (See: List of adaptive radiated honeycreepers)
