Black-Capped & Carolina Chickadees: U.S. States With Both Species
Chickadees are among our most familiar and favorite birds. In the eastern U.S., the two common species are the Black-capped Chickadee in the north (the state bird of Maine and Massachusetts) and the Carolina Chickadee in the south. The pair is more similar to each other than to other chickadee species in North America, and they overlap and hybridize in a narrow zone - no more than about 20 miles wide - on an irregular line from Kansas east to New Jersey; Black-capped Chickadees can also be found in high elevations of the Great Smoky Mountains of North Carolina and Tennessee, where more widespread Carolinas replace them in the lowlands. This is a list of U.S. states where both species occur regularly, but which one is the "local" chickadee depends on your location. If you're a birder like me, you'd make the effort to see both!
