Birdfinding.info ⇒ One of the most abundant and familiar songbirds of North America, it frequents backyard bird feeders nearly throughout Canada and in the northern half of the U.S. Especially abundant in the Northeast, including the Great Lakes, New York, New England, and the Maritime Provinces.
Black-capped Chickadee
Poecile atricapillus
Woodlands of northern and central North America.
Widespread in forests and woodlands, including urban and suburban neighborhoods, across the full breadth of North America from western Alaska to Newfoundland and south to northern California, southern Utah, northern New Mexico, southern Kansas, central Illinois, all of New England, and New York, most of Pennsylvania, and in the Appalachians south to western North Carolina.

Mostly absent from the rain forest zone of coastal British Columbia and southeastern Alaska, and thinly distributed in the Rocky Mountains and Great Basin south of Montana.
In the Appalachians from south-central Pennsylvania to western North Carolina, Black-capped breeds at higher elevations than the Carolina Chickadee. The threshold elevation varies from approximately 1,000 m to 1,800 m (generally becoming higher southward).
Mostly resident over most of its range, but with local winter movements downslope in the mountains and for short distances south of the usual breeding range.
Identification
The common chickadee of Canada and the northern U.S. It overlaps with a few related species, but is readily confused only with the Carolina Chickadee in the eastern U.S. Apart from a subtle difference in wing pattern, they are nearly identical. (See below for a detailed comparison.)
Instantly recognized as a chickadee by its bold head pattern: a jet-black crown and throat with contrasting white cheeks.

The upperparts are mostly medium-gray, but vary somewhat from one population to another. Some are cold shades of gray, and others are more olive or brownish-gray. As a general rule, the northern and eastern populations tend to be cold-gray, and the western populations tend to be browner or more olive.
The wings often appear mostly white, especially the flight feathers. The greater wing coverts are usually two-toned: white on the inner portion and gray on the outer portion. This contrast within the greater coverts is the most diagnostic feature for separating Black-capped from Carolina Chickadee. (But note that some western Black-capped populations do not show this contrast consistently.)

The underparts typically show an extensive buffy or cinnamon wash along the sides, and are otherwise whitish.

Voice. Best known for its signature chick-a-dee call, which is lower-pitched and slower than the Carolina Chickadee’s equivalent call:The typical song is a clear, two-note whistle (high-low):Sometimes gives a three-note variant:Also various chip notes and jumbled calls, including rapid gurgles:
Notes
Polytypic species consisting of nine recognized subspecies.
See below for a comparison of the Black-capped Chickadee with the Carolina Chickadee.
Cf. Carolina Chickadee. The Black-capped and Carolina Chickadees occur together, or near one another, in a band that extends from southern Kansas across central Missouri and Illinois and northern Indiana and Ohio to central New Jersey—and much more widely in the Appalachians from central Pennsylvania south to western North Carolina. In summer, the two populations remain mostly separate, with Black-capped occupying higher elevations of the Appalachians, although they are known to interbreed occasionally. In winter, Black-capped invades Carolina’s territory, at least locally.
They can be extremely similar and both vary enough internally that some individuals are ambiguous. With hybrids known to occur at least occasionally, some are simply not identifiable. For the ones that are merely similar, the most consistent differences are their voices and the color patterns on their wings.

Their typical songs differ. Black-capped gives a clear two-note whistle (high-low), whereas Carolina typically gives a four-note whistle (high-low, high-low). Each species gives its own version of the chick-a-dee call, but Black-capped’s is lower-pitched and has a slower cadence: 3 to 4 notes per second. Carolina’s call is about 5 to 7 notes per second. Vocalizations alone are sometimes misleading, however, as individuals in the contact zone have sometimes been observed adopting the calls of the other species.
Visually, Carolina averages grayer overall, especially on the wings. Carolina’s wings are nearly uniform gray, whereas Black-capped’s wings have pronounced, often uneven, white markings on the flight feathers and wing coverts. In most cases, Black-capped shows a contrast within the greater wing coverts—where the outer portion is relatively dark or medium-gray and the inner portion is white or whitish.
