Tufted Titmouse

We found this titmouse at the Ray Roberts Lake State Park near Denton, Texas, on 17 March 2016. Tufted Titmice are abundant across most of eastern North America, but less so in the north. Their range, however, is expanding northward. This change may be due to global warming and/or increased use of bird feeders by birders.

The titmouse’s song, “peter-peter-peter-peter” is a dominant sound in most forested areas of the southeast. Titmice are a “nuclear species” in mixed flocks of forest birds. The other species follow the titmice, which often know where food supplies lie or where feeders exist.  Titmice also aggressively mob predators, thus alerting the other birds of danger (Ritchison et al. 2015).
