The darker the color, the more favorable the climate conditions are for survival. The outlined areas represent approximate current range for each season. More on reading these maps.
Closely related to the familiar Tufted Titmouse in the eastern U.S., the range-restricted Black-crested Titmouse is widespread in southern, central, and western Texas. Where the two titmouse species overlap, there is extensive hybridization. Audubon’s climate model forecasts an unstable climate future for the Black-crested Titmouse: only 14% of the current core of suitable climate space remains stable, but with gains north and east of the current range. If the Black-crested follows the predicted expansion northeastward, it will come into increased contact with the Tufted Titmouse, raising the possibility of extensive interbreeding of the two species.
