Black-capped Chickadee vs Carolina Chickadee
These two chickadees look nearly alike and hybridize where their ranges meet, a narrow band running roughly from Kansas to New Jersey. Location is often the best clue; wing edging and song back it up.
| Field mark | Black-capped Chickadee | Carolina Chickadee |
|---|---|---|
| Range | Northern U.S. and Canada; Appalachian peaks | Southeastern U.S. |
| Wing coverts | Broad, bright white edges | Greyer, little white edging |
| Bib edge | Ragged lower edge | Neater, sharper lower edge |
| Size | 4.7–5.9 in, longer tail | 3.9–4.7 in, shorter tail |
| Song | Two notes: "fee-bee" | Four notes: "fee-bee-fee-bay" |
| Call | Slower, lower "chick-a-dee-dee" | Faster, higher "chick-a-dee-dee" |
Field tips
- Inside the hybrid zone, birds can sing each other's songs — combine several marks.
- In winter, Black-capped Chickadees occasionally wander south of their normal range.
- Both use a 1 1/8 in entrance hole, so one nest box design serves either species.

Frequently asked
Can Black-capped and Carolina Chickadees interbreed?
Yes. They hybridize along a narrow contact zone, and hybrids can show intermediate plumage and mixed songs.
Which chickadee lives in my area?
Carolina in the Southeast, Black-capped in the North and Canada. In the contact zone (southern Pennsylvania, central Ohio, parts of the Midwest) either or hybrids occur.
What nest box do chickadees need?
A 4 × 4 in floor, 8–10 in depth, and a 1 1/8 in entrance hole. Adding an inch of wood shavings helps, since chickadees like to excavate.
