The Black-capped Chickadee (Poecile atricapillus) often joins foraging flocks of other species and feeds on insect eggs, and seeds from conifers and bayberry trees. It is a common and familiar garden and feeder bird.
This species is mostly gray with black cap and throat and white cheek patch. Chickadees that look somewhat alike can often be told apart by their sounds. Fee-bee, this species whistles, the first note of the song a full tone higher than the second.
Its call is the familiar chick-a-dee. In the Middle West and Southeast the longer, more sibilant su-fee, su-bee, ending on a low note. Its chick-a-dee calls are more rapid.
