Tufted Titmouse
Order: Passeriformes
Tufted titmouse (Parus bicolor) is in the family Paridae.
A cousin of the chickadee, the tufted titmouse is common in deciduous woodlands, particularly in the Southeast. His crest identifies him as he scrounges for seeds, insects, small acorns, etc. I've seen them take a seed from the bird feeder, carry it to a nearby tree branch, and break it open to eat.
They are "scolders" and sound similar to the chickadee's scolding notes, only the titmouse's scolding has an upward inflection at the end of each note.
His song is the familiar Peter, Peter, Peter! ... not to be mistaken by the similar-sounding Carolina wren's song.
