Baby chimney swifts are altricial—naked, blind and helpless when they hatch. Fledglings leave the nest after a month. [57] The average chimney swift's life span is 4.6 years, [60] but one is known to have lived more than 14 years. It was originally banded as an adult, and was recaptured in another banding operation some 12.5 years later. [61]
Roughly 70 to 80 types of swifts live worldwide, but only the chimney swift is native east of the Rocky Mountains. The birds head north in March , nesting in April and May to lay four to five eggs.
All swifts eat insects, such as dragonflies, flies, ants, aphids, wasps and bees as well as aerial spiders. Prey is typically caught in flight using the beak. Some species, like the chimney swift, hunt in mixed species flocks with other aerial insectivores such as members of Hirundinidae (swallows). [18]

Thousands of birds flock in great living tornados, then funnel into the chimney. Estimates of 1,700 to 35,000 swifts have been reported in various years. Shortly after sunset, over a period of roughly 30 minutes, they fly into the top of the brick chimney (constructed c.1925) to roost on the interior surface until they depart at sunrise. [8]
Chimney swift. Order: Apodiformes Family: Apodidae. The swifts are small birds which spend the majority of their lives flying. These birds have very short legs and never settle voluntarily on the ground, perching instead only on vertical surfaces. Many swifts have very long, swept-back wings which resemble a crescent or boomerang.
