The bushtits or long-tailed tits, Aegithalidae, are a family of small, drab passerine birds
with moderately long tails. They are small birds, measuring 9 to 14 cm (3.5–5.5 in) in length, including the relatively long tail, and weighing just 4.5 to 9 g (0.16–0.32 oz). Their plumage
is typically dull grey or brown, although some species have white markings and the long-tailed tit has some pinkish colour.
