Black Capped Chickadee

The Black-capped Chickadee occurs in deciduous or mixed forests, tall thickets of shrubs, coniferous forests, and in residential areas. It nests in a cavity of a tree, an old woodpecker hole or a bird house. Its song is an unforgettable chicka-dee-dee-dee. The Black-capped Chickadee (Poecile atricapillus) is a small, North American songbird, a passerine bird in the tit family Paridae. It is the state bird of both Maine and Massachusetts in the United States, and the provincial bird of New Brunswick in Canada. It is notable for its capacity to lower its body temperature during cold winter nights, its good spatial memory to relocate the caches where it stores food, and its boldness near humans (they can feed from the hand). Its French name is Mésange à tête noire.
The Black-capped Chickadee has a black cap and bib with white sides to the face. Its underparts are white with rusty brown on the flanks. Its back is gray and the tail is normally slate-gray. This bird has a short dark bill (8.0-9.5 mm), short rounded wings (63.5-67.5 mm) and a long tail (58–63 mm). Total body length is 12–15 cm (4.7–5.9 in), wingspan is 16–21 cm (6.3–8.3 in) and body mass is 9–14 g (0.32–0.49 oz).[3] Sexes look alike, but males are slightly larger and longer than females.
Although range can generally be used to separate them, the Black-capped Chickadee is very similar in appearance to the Carolina Chickadee. The Black-capped is larger on average but this cannot be used reliably for identification. The most obvious difference between the two is in the wing feathers. In the Black-capped Chickadee, the wing feathers have white edges that are larger and more conspicuous than those of the Carolina Chickadee. Overall, the Carolina appears slightly paler colored whereas the flanks of the Black-capped can appear to have a trace of off-yellow or rusty coloration. Also, the Black-capped generally has a more "ragged" looking black bib, whereas the bib of the Carolina has a more smooth-edged look. These subtle features are often even more vague in populations around where the Black-capped and Carolina overlap in range (possibly the result of hybrids) and the two cannot always be distinguished to species. The two species were formerly thought to be easily distinguished by call, but they often learn each other's vocalizations where their ranges overlap (their point of overlap is a narrow band that runs along the east-central United States, with the Black-capped Chickadee to the north). A bird located near the zone of overlap that sings both songs, or sings "odd-sounding" songs, cannot be positively identified solely by voice in the field. Wikipedia
