Black-crested titmouse

The black-crested titmouse or Mexican titmouse (Baeolophus atricristatus), is a passerine bird in the tit family Paridae. Once considered a subspecies of the tufted titmouse (B. bicolor), it was recognized as a separate species^[2] in 2002. It is native to southern Texas, Oklahoma, and east-central Mexico. Vagrants have been seen as far north and east as St. Louis, Missouri.
