From Audubon:  Black-capped Chickadee

Little flocks of Black-capped Chickadees enliven the winter woods with their active behavior and their cheery-sounding chick-a-dee callnotes as they fly from tree to tree, often accompanied by an assortment of nuthatches, creepers, kinglets, and other birds. This is a very popular bird across the northern United States and southern Canada, always welcomed at bird feeders, where it may take sunflower seeds one at time and fly away to stuff them into bark crevices.
