Swifts are aerial birds that spend most of their time flying. They are aerial insectivores, which means they eat insects while flying. Swifts typically build their nests in the eaves of buildings or other man-made structures.
Swifts do not sleep like most other birds. Instead, they enter a state of torpor, which is a type of deep sleep. Torpor is extremely similar to hibernation, but unlike hibernation, the animal does not fully shut down. Swifts typically enter torpor when cold weather arrives and remains in this state until hunger wakes them up or warmer weather returns.

In addition to sleeping in a state of torpor, swifts will also sleep while flying. These birds can fly long distances without having to land for a break. The period of time they sleep while flying is typically going from their nesting location to another location where they find food.

Swifts tend to build their nests during the spring and will lay three to five eggs. The parents tend to their young until they are old enough to enter torpor on their own. At this point, the young swifts fly away and the parents begin mating again in hopes of having another set of offspring.

Swifts typically hunt for food during daylight hours. They will go into a state of torpor during the evening hours and will continue to sleep until hunger wakes them up again.

Torpor is a natural occurrence in swifts and allows them to survive harsh weather conditions. If the temperature drops, they will find shelter and enter torpor for a few days until better weather returns. This allows them to conserve energy while waiting for the temperature to rise again.

Swifts will spend their first two to three weeks after hatching in the nest with their parents until they are old enough to fly. During this time, the young will be fed by their parents until they are ready to begin hunting for food on their own.
