Black-capped Chickadees are resident birds across their range, which spans much of the northern half of North America. In their range, they are common back yard feeder birds, often found in mixed flocks with other species like nuthatches, creepers, and woodpeckers. Black-capped Chickadees have a complex range of calls, including their alarm "chickadee-dee-dee" call. The more "dees" you hear, the more alarmed the bird is!
Those calls come pretty fast, though. Try to count the number of "dees" you hear, next time a Chickadee is near! Or give it a try with this recording:
