The black-crested titmouse, found from central and southern Texas southward,[2] was included as a subspecies but now is considered a separate species, Baeolophus atricristatus.

Measurements:[4] A small bird, the tufted titmouse has a white front and gray upper body outlined with rust-colored flanks.

Although it is non-migratory and originally native to the Ohio and Mississippi River basins, factors such as bird feeders have caused it to occupy a larger territory across the United States and stretching into Ontario and Quebec in Canada.

[4] The tufted titmouse gathers food from the ground and from tree branches, frequently consuming a variety of berries, nuts, seeds, small fruits, insects, and other invertebrates.

[9][11] The tufted titmouse can demonstrate curiosity regarding humans and sometimes will perch on a window ledge and seem to be peering into the house.

[4] This species readily forms small flocks, known as troupes or banditries, which often associate with chickadees and other passerines when foraging.
