The Carolina chickadee (Poecile carolinensis) is a small passerine bird in the tit family Paridae.
The Carolina chickadee was often placed in the genus Parus with most other tits, but mtDNA cytochrome b sequence data and morphology suggest that separating Poecile more adequately expresses these birds' relationships. [2] The American Ornithologists' Union has been treating Poecile as distinct genus since 1998. [3] Although it and the black-capped chickadee most likely diverged about 2.5 million years ago, the birds still hybridize in the areas where their ranges overlap. [4] The offspring of mated pairs of hybrid chickadees suffer from lower hatching success, and a male bias sex ratio, consistent with Haldane's rule. [5]
Adults are 11.5–13 cm (4.5–5.1 in) long with a weight of 9–12 g (0.32–0.42 oz), and have a black cap and bib with white sides to the face. Their underparts are white with rusty brown on the flanks; their back is gray. They have a short dark bill, short wings and a moderately long tail. Very similar to the black-capped chickadee, the Carolina chickadee is distinguished by the slightly browner wing with the greater coverts brown (not whitish fringed) and the white fringing on the secondary feathers slightly less conspicuous; the tail is also slightly shorter and more square-ended. Without calls, visual distinction between the two species is very difficult even with an excellent view.
Eggs are about 1.5 cm (0.6 in) long and 1.1 cm (0.4 in) wide. Eggs are white with areas of reddish-brown ranging from dots to small blotches. [4]
The calls and song between the Carolina chickadee and the black-capped chickadee differ subtly to an experienced ear: the Carolina chickadee's chick-a-dee call is faster and higher pitched than that of the black-capped chickadee, and the Carolina chickadee has a four note fee-bee-fee-bay song, whereas the black-capped omits the high notes. [6]
The most famous call is the familiar chick-a-dee-dee-dee,[ citation needed ] which gave this bird its name. Its song is fee-bee-fee-bay.
Their breeding habitat is mixed or deciduous forests in the United States from New Jersey and Pennsylvania west to southern Kansas and south to Florida and Texas; there is a gap in the range at high altitudes in the Appalachian Mountains where they are replaced by their otherwise more northern relative, the black-capped chickadee.
They are permanent residents, not usually moving south even in severe winter weather.
These birds hop along tree branches searching for insects, sometimes hanging upside down or hovering; they may make short flights to catch insects in the air. Insects form a large part of their diet, especially in summer; seeds and berries become important in winter. They sometimes hammer seeds on a tree or shrub to open them; they also will store seeds for later use. Carolina chickadees commonly make use of feeders. [4]
During the fall migration and winter, chickadees often flock together in flocks of 8–10 birds. Each of the birds in a flock has a rank; while highly ranked birds will remain on the flock's territory for breeding, lower-ranked birds must find new breeding territory. Many other species of birds, including titmice, nuthatches, and warblers can often be found foraging in these flocks. Mixed flocks occur about 50% of the time. Mixed flocks stay together because the chickadees call out whenever they find a good source of food. This calling out forms cohesion for the group, allowing the other birds to find food more efficiently. [4]
Carolina chickadees actively defend individual spaces of 2–5 ft (0.6–1.5 m) apart; if another bird encroaches on these spaces, the dominant bird may make gargle calls. At feeders, these birds will usually take a seed and fly to a branch isolated from other birds to eat it. [4]
These birds usually sleep in cavities, though they may sleep in branches. Different members of a flock will sleep in the same cavity from night to night. While females usually sleep in the nest cavity, males will normally sleep on a nearby branch. [4]
They nest in a hole in a tree; the pair excavates the nest, using a natural cavity or sometimes an old woodpecker nest. They may interbreed with black-capped chickadees where the ranges overlap, which can make identification even more difficult. The female will build the nest out of moss and strips of bark; she will then line it with hair or plant fibers. Clutches are usually made up of 3–10 eggs with an incubation period of 12–16 days. The nestling period is usually 16–19 days. [4]
Carolina chickadees are able to lower their body temperatures to induce an intentional state of hypothermia called torpor. They do this to conserve energy during extremely cold winters. In extreme cold weather conditions they look for cavities where they can hide in and spend up to fifteen hours at a time in torpor. During this time they are awake but unresponsive; they should not be picked up and handled at this time because the stress of being held may cause death. [7]
The penduline tits constitute the family Remizidae, of small passerine birds related to the true tits. All but the verdin make elaborate bag nests hanging from trees, usually over water.
The American bushtit, or simply bushtit, is a social songbird belonging to the genus Psaltriparus. It is one of the smallest passerines in North America and it is the only species in the family Aegithalidae that is found in United States; the other seven species are found in Eurasia.
The tits, chickadees, and titmice constitute the Paridae, a large family of small passerine birds which occur mainly in the Northern Hemisphere and Africa. Most were formerly classified in the genus Parus.
The ground tit, Tibetan ground-tit or Hume's ground-tit is a bird of the Tibetan plateau north of the Himalayas. The peculiar appearance confused ornithologists in the past who called it as Hume's groundpecker and still later as Hume's ground jay or Tibetan ground jay assuming that it belonged to the family Corvidae that includes the crows and jays. Although morphologically confusing, the species has since been identified using molecular sequence comparisons as being a member of the tit family (Paridae) and is the only species in the genus Pseudopodoces. It is found in the Tibetan Plateau of China, India, Nepal & Bhutan.
The marsh tit is a Eurasian passerine bird in the tit family Paridae and genus Poecile, closely related to the willow tit, Père David's and Songar tits. It is a small bird, around 12 cm (4.7 in) long and weighing 12 g (0.42 oz), with a black crown and nape, pale cheeks, brown back and greyish-brown wings and tail. Between 8 and 11 subspecies are recognised. Its close resemblance to the willow tit can cause identification problems, especially in the United Kingdom where the local subspecies of the two are very similar: they were not recognised as separate species until 1897.
The willow tit is a passerine bird in the tit family, Paridae. It is a widespread and common resident breeder throughout temperate and subarctic Europe and across the Palearctic. The plumage is grey-brown and off-white with a black cap and bib. It is more of a conifer specialist than the closely related marsh tit, which explains it breeding much further north. It is resident, and most birds do not migrate.
The white-breasted nuthatch is a species of bird in the nuthatch family Sittidae. It is a medium-sized nuthatch, measuring approximately 15.5 cm (6.1 in) in length. Coloration varies somewhat along the species' range, but the upperparts are light blue-gray, with a black crown and nape in males, while females have a dark gray crown. The underparts are whitish, with a reddish tinge on the lower abdomen. Despite not being closely related, the white-breasted nuthatch and the white wagtail are very similar in plumage. The white-breasted nuthatch is a noisy bird. It has a nasal voice and often utters little cries or vocalizations, often composed of repetitions of small invariant whistles. In summer, it is an exclusively insectivorous bird, consuming a wide range of arthropods, but in winter its diet consists mainly of seeds. The nest is located in the cavity of a tree. The clutch consists of five to nine eggs, incubated for two weeks by the female, who is fed by the male. The two adults then feed the young until they fledge, and for a few weeks after that.
The black-capped chickadee is a small, nonmigratory, North American passerine bird that lives in deciduous and mixed forests. It is a member of the Paridae family, also known as tits. It has a distinct black cap on its head, a black bib underneath, and white cheeks. It has a white belly, buff sides, and grey wings, back, and tail. The bird is well known for its vocalizations, including its fee-bee call and its chick-a-dee-dee-dee call, from which it derives its name.
The boreal chickadee is a small passerine songbird in the tit family Paridae. It is found in the boreal forests of Alaska, Canada and the northern United States and remains within this range all year. This bird is known for its high pitched trill patterns used in communication with other birds and food storage habits in preparation for winter months.
The tufted titmouse is a small songbird from North America, a species in the tit and chickadee family (Paridae). The black-crested titmouse, found from central and southern Texas southward, was included as a subspecies but now is considered a separate species, Baeolophus atricristatus.
The grey-headed chickadee or Siberian tit, formerly Parus cinctus, is a passerine bird in the tit family Paridae. It is a widespread resident breeder throughout subarctic Scandinavia and the northern Palearctic, and also into North America in Alaska and the far northwest of Canada. It is a conifer specialist. It is resident, and most birds do not migrate. Curiously, the bird has no grey on its head, which is black, white, and brown.
The azure tit is a passerine bird in the tit family Paridae. It is a widespread and common resident breeder throughout Russia, Central Asia, northwest China, Manchuria, and Pakistan.
The mountain chickadee is a small songbird, a passerine bird in the tit family Paridae.
The Mexican chickadee is a small songbird, a passerine bird in the tit family Paridae. It is still often placed in the genus Parus with most other tits, but mtDNA cytochrome b sequence data and morphology suggest that separating Poecile more adequately expresses these birds' relationships. The American Ornithologists' Union had been treating Poecile as distinct genus for some time already.
The sombre tit is a member of the tit family found in southeast Europe and southwest Asia. Sombre tits occur in low density in thin woodlands at the elevation range between 1000 and 1600 metres above sea level.
The oak titmouse is a passerine bird in the tit family Paridae. The American Ornithologists' Union split the plain titmouse into the oak titmouse and the juniper titmouse in 1996, due to distinct differences in song, preferred habitat, and genetic makeup.
The juniper titmouse is a passerine bird in the tit family Paridae. The American Ornithologists' Union split the plain titmouse into the oak titmouse and the juniper titmouse in 1996, due to distinct differences in song, preferred habitat, and genetic makeup.
The chestnut-backed chickadee is a small passerine bird in the tit family, Paridae, native to western North America.
The fire-capped tit is a small, 10 cm (3.9 in) long, weighing about 7 g (0.25 oz) bird species assigned to the family Paridae, that breeds in the temperate forest bordering the Himalayas to the south, in the Hengduan Shan and Nujiang Shan on the Myanmar-China border, the Micah Shan and Daba Shan on the Northern Sichuan border. It winters down hill and further south. Further to the east, birds tend to be smaller and the plumage becomes gradually darker.
The chickadees are a group of North American birds in the family Paridae included in the genus Poecile. Species found in North America are referred to as chickadees; species found elsewhere in the world are called tits. They are small-sized birds overall, usually having the crown of the head and throat patch distinctly darker than the body. They are at least 6 to 14 centimeters in size.
