The tufted titmouse (Baeolophus bicolor) is a small songbird from North America, a species in the tit and chickadee family ().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.
This bird is a permanent resident in much of its range. Northern birds migrate in flocks to the Southeastern United States. The distribution of the common grackle is largely explained by annual mean temperature, and the species has expanded its range by greater than three-fold since the last glacial maximum, approximately 22,000 years ago.

This article lists living orders and families of birds. In total there are about 10,000 species of birds described worldwide, though one estimate of the real number places it at almost twice that. [1] The order passerines (perching birds) alone accounts for well over 5,000 species.
Some bird species undertake shorter migrations, travelling only as far as is required to avoid bad weather or obtain food. Irruptive species such as the boreal finches are one such group and can commonly be found at a location in one year and absent the next. This type of migration is normally associated with food availability. [178]
For species found in the 50 states, Puerto Rico, and the U.S. Virgin Islands, the taxonomic treatment (designation and sequence of orders, families and species) and nomenclature (common and scientific names) used in the list are those of the AOS, the recognized scientific authority on the taxonomy and nomenclature of North and Middle American birds.
