The pied-crested tit-tyrant (Anairetes reguloides) is a species of bird in subfamily Elaeniinae of family Tyrannidae, the tyrant flycatchers.

[2] The members of genus Anairetes are known commonly as tit-tyrants because their active foraging behavior and crests are reminiscent of the true tits in the family Paridae.

[4] The pied-crested tit-tyrant has two subspecies, the nominate A. r. reguloides (D'Orbigny & Lafresnaye, 1837) and A. r. albiventris (Chapman, 1924).

Adult males of the nominate subspecies have a dramatic split black crest formed by elongated feathers on the sides of the crown.

Their breast and flanks are streaked with black and white and their belly and undertail coverts are whitish with a faint yellow tinge.

The nominate subspecies is found from southern Ayacucho south into extreme northwestern Chile's Arica Province.

The species inhabits the generally arid coastal region, where it is found in scrublands, thickets along watercourses, in "fog oasis" lomas, and in hedgerows in agricultural plots.

It is an active feeder, taking prey mostly by gleaning from leaves and twigs while perched and making short upward flights to hover-glean.
