Chickadee

 ( Bird Common Names ) 

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 (2.4 to 5.5 inches) in size.

Their name reputedly comes from the fact that their calls make a distinctive "chick-a-dee-dee-dee", though their normal call is "fee-bee", and the "chick-a-dee-dee-dee" call is an alarm call. The number of "dees" depends on the predator. "Chirpy chickadees signal deadliness of predators". New Scientist. 23 June 2005. Retrieved 6 March 2019.

The chickadee (specifically the black-capped chickadee Poecile atricapillus, formerly Parus atricapillus) is the official bird for the US state of Massachusetts, Massachusetts Facts Secretary of the Commonwealth.

The chickadee is also the state bird of Maine, but a species has never been specified. A proposed bill in 2019 would have named the black-capped chickadee as the official species for Maine, but was unanimously voted down in committee. The de facto species for Maine remains the black-capped.

One holarctic species is referred to by a different name in each part of its range: grey-headed chickadee in North America and Siberian tit in Eurasia.

Habitat Chickadees are native to North America, where they are very common. In North America, the birds are found from the East Coast to the West Coast, and from Canada to Mexico. Chickadees' preferred habitats include mixed deciduous or coniferous forests, parks, open woods, cottonwood groves, willow thickets, and disturbed areas.

Memory Mountain chickadees are food-caching birds. A single bird can hide as many as 80,000 individual seeds, which they retrieve during the winter. Their ability to do so depends on their spatial memory of the locations. Birds that live in harsher conditions, where their ability to remember the location of food is more important, have been found to have better memory abilities, a larger hippocampus, and more neurons than chickadees that live in milder climates where food sources are easier to find without relying on memory.
