-37 Chimney Swifts
Chimney Swifts are a swift of the family Apodidae. They spend most of their life in the air only landing to nest and rest in the roost. They mate for life and life to an average of 4 1/2 years. They are quite acrobatic and feed on flying insects. They have weak legs and can only cling to a vertical surface. They have been in decline due to loss of natural habitat and loss of manmade structures such as chimneys. This video was taken during a chimney swift count where people gather together to count the number of swifts that enter the roost to help gauge how the population is doing. During this evening ~2500 swifts were counted entering this chimney. The previous evening ~5000 swifts were counted entering the roost. In the fall they will migrate to South America.
