Tufted Titmouse

This rather tame, active, crested little bird is common all year in eastern forests, where its whistled peter-peter-peter song may be heard even during mid-winter thaws. It is related to the chickadees, and like them it readily comes to bird feeders, often carrying away sunflower seeds one at a time. https://www.audubon.org/field-guide/bird/tufted-titmouse
