European Swift, scientifically known as Apus apus, is a small migratory bird species that belongs to the family Apodidae. It is commonly found in Europe, hence the name "European Swift." This bird species is known for its exceptional aerial agility and speed, making it one of the fastest bird species in the world. It has a distinct appearance with a slender and streamlined body, long and scythe-shaped wings, and a short forked tail.
The European Swift measures approximately 16-17 centimeters in length, with a wingspan of about 41-44 centimeters. It has a predominantly dark brown to black plumage, while its throat and belly are paler in color. Its beak is short and wide, built specifically for catching insects in flight. European Swifts are highly adapted to an aerial lifestyle, spending most of their lives airborne, only landing to breed and during migration.
These birds are known for their remarkable flying ability, capable of reaching incredible speeds of up to 100 km/h (62 mph). They are also exceptional migratory birds, traveling long distances annually to breed and overwinter. European Swifts are primarily insectivorous, feeding on a wide variety of flying insects, such as mosquitoes, flies, and beetles.
Furthermore, European Swifts have a unique reproductive behavior. They form monogamous pairs and breed in colonies, typically nesting in cavities found in buildings, cliffs, or trees. Their nests are constructed using straw, feathers, and saliva, usually in concealed locations. The female lays one to three eggs, which are incubated by both parents for about three weeks. After hatching, the chicks are fed regurgitated food brought by the adult swifts, and they fledge after about 45 days.
