Chestnut-backed Chickadee – Natural Bird Sound

The chestnut-backed chickadee is a small passerine bird in the tit family, Paridae. It is found in the Pacific Northwest of the United States and western Canada, from southern Alaska to southwestern California. It is a permanent resident within its range, with some seasonal movements as feeding flocks move short distances in search of food.

Chickadees are able to use nocturnal hypothermia to regulate energy expenditure, allowing them to survive harsh winters where other bird species not utilizing thermal regulation would not be able to. Some estimates put the energy conserved while using nocturnal hypothermia all the way up to 32%.
