Chickadee

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. ==Species==
