The Black-capped Chickadee (Poecile atricapillus) and the Carolina Chickadee (Poecile carolinensis) can be confusing species for eastern bird watchers to identify. The ranges of these species do not overlap much, so for many people a quick look at a range map will show which species are most likely to occur at their feeders. But for those who live in the zone of overlap, a fairly stable and narrow band that runs along the east-central United States, the chickadees pose a serious identification challenge. To complicate matters, the species have been known to hybridize in the overlap zone.  When identifying these two chickadees, concentrate equally on the differences in plumage and the differences in vocalizations.

A small (avg. 5.25" long), acrobatic bird with longer tail and (to some observers) a proportionately larger head. The smallest (avg. 4.75"" long) North American chickadee with a proportionately smaller head and shorter tail.

sexes similar

-The lower edge of the black bib is less defined and appears uneven. Mostly white on nape of neck.

-In fresh plumage (usually in the autumn) the greater wing coverts (marked with an arrow in picture above) and secondaries are broadly edged in white.

-The white patch on the wing is more exaggerated.

-The outer tail feathers are more broadly edged with white on the Black-capped Chickadee.

-The bib is smaller and well defined (there is a neat line of separation between the bib and belly). Mostly greyish on nape of neck.

-The greater wing coverts (marked with an arrow in picture above) are more uniformly grey and show less white.

-The cinnamon-buff coloring under the wings is less developed on the Carolina Chickadee (but fresh adults in the northeast part of its range show brighter cinnamon and can be confused with Black-capped)

Bird watchers near the zone of overlap are encouraged to take extra precaution
with the identification of these species.

Songs and Calls

Near the zone of overlap, birds have been known to learn each other's vocalizations, and hybrids tend to deliver odd-sounding variations. A bird located near the zone of overlap that sings both songs, or sings "odd-sounding" songs, cannot be positively identified in the field.

-The Black-capped's call is a lower and slower chick-a-dee-dee-dee. Functions as a contact call, one that serves to keep the winter flock together when birds cannot see one another.

-It's song is a clear fee-bee. A loud version given during territory skirmishes, a soft version given during mate feeding.

-The Carolina's call is a higher and faster chick-a-dee-dee-dee.

-It also has a four note song, fee-bee-fee-bay.

This Winter, 1999 article discusses the geographic distribution, habitat, and migratory and feeding habits of these two species.  Birdscope is the quarterly newsletter received by Project FeederWatchers and members of the Cornell Lab of Ornithology.

Bird-of-the-Week: Black-capped Chickadee, Carolina Chickadees

The Cornell Lab of Ornithology Bird-of-the-Week series contains detailed species accounts as well as photographs and paintings from a variety of sources. Each also contains identification tips that compare and contrast similar-looking species.
