No. The Common Swift is one of the fastest-flying birds found in Europe. When members of a colony get together and fly screaming at full speed over their territory, they can reach 220 km/h in dives. Only the Alpine Swift (Apus melba), which can dive at 250 km/h, and the Hobby (Falco subbuteo), are faster than the Common Swift.
