The Family Apodidae comprises the swifts, small to medium-sized birds renowned for their exceptional aerial abilities. They have long, narrow wings and streamlined bodies adapted for rapid, agile flight, spending most of their lives on the wing and rarely perching. Swifts have short legs, which are primarily used for clinging to vertical surfaces rather than walking, and feed almost exclusively on airborne insects, capturing them in flight. Found worldwide, especially in tropical and temperate regions, Apodidae play an important ecological role as insect predators, helping control pest populations. Their nesting habits vary, with some species using natural crevices or cliffs, and others utilizing man-made structures.
