The Tufted Titmouse is found in woodlands, shade trees, groves. Mostly in deciduous forest with tall trees, sometimes in mixed forest. Can live in orchards, suburbs, or even city parks if trees are large enough.
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. Feeders may be helping it to expand its range: in recent decades, Tufted Titmice have been steadily pushing north.
