The black-browed bushtit or black-browed tit (Aegithalos bonvaloti) is a species of bird in the family Aegithalidae. It is found in mid-southern China and sporadically in Myanmar. Its natural habitats are boreal forests and temperate forests. It was formerly considered conspecific with the rufous-fronted tit (A. iouschistos) of the central and eastern Himalayas but is now often regarded as a separate species. Sometimes the subspecies A. b. sharpei (Burmese tit) of western Burma is also treated as a species.
It is a small, long-tailed bird, 11– long. It has grey upperparts, rufous breast and flanks and a white belly. The head is buff with a broad black mask, white forehead and a white bib, speckled black in the centre. The Burmese tit has white rather than buff on the head, a dark breastband and a buff belly.
