The family Apodidae, commonly known as swifts, consists of small, agile birds known for their incredible flying abilities. They have long wings and a streamlined body, allowing them to reach high speeds and perform acrobatic maneuvers in the air. Swifts are primarily insectivorous, feeding on flying insects while in flight. Swifts are found worldwide, except in polar regions and some isolated islands. They are known for their unique nesting habits, often building nests in high, inaccessible places such as cliffs or under eaves. Many species are migratory, traveling long distances between breeding and wintering grounds.
