The bushtits or long-tailed tits are small passerine birds from the family Aegithalidae, containing 13 species in three genera, all but one of which (Psaltriparus) are found in Eurasia. Bushtits are active birds with long tails compared to their size, moving almost constantly while they forage for insects in shrubs and trees. During non-breeding season, birds live in flocks of up to 50 individuals. Several bushtit species display cooperative breeding behavior, also called helpers at the nest.
