The long-tailed tits or bushtits (Aegithalidae), are a family of 13 species of small passerine birds.

Their plumage is typically dull grey or brown, although some species have white markings and the Long-tailed Tit has some pinkish colour. In contrast to the rest of the family the two Leptopoecile tit-warblers are quite brightly coloured, having violet and blue plumage. All the Aegithalidae are forest birds, particularly forest edge and understory habitats.

They are omnivorous, primarily eating insects and other invertebrates. Plant material is taken occasionally during the winter. The family generally forages in arboreally, usually in the shrub layer or canopy, and seldom visits the ground. Prey is generally glean from branches, leaves and buds, more rarely is it taken in the air. While foraging this agile family may hang upside down on branches and even manipulate branches and leaves in order to locate hidden food.
