Black-throated bushtit

In older sources, "black-throated tit" can also mean the rufous-naped tit or the rufous-vented tit, which are true tits.

The black-throated bushtit (Aegithalos concinnus), also known as the black-throated tit, is a very small passerine bird in the family Aegithalidae.

The black-throated bushtit is a small passerine, around 10.5 cm (4.1 in) long and weighing 4–9 g (0.14–0.32 oz). There is considerable racial variation in the plumage, but all subspecies have a medium length tail (as opposed to the long tail of the related long-tailed tit), a black throat and a black 'bandit mask' around the eye. The nominate race has a chestnut cap, breast band and flanks and dark grey back, wings and tail, and a white belly. The other subspecies have generally the same pattern (minus the chest band) but with grey caps or all grey bellies and flanks. Both sexes are alike.
