Quick Answer. Hummingbirds fly backwards, and they are the only birds capable of doing so. When using this unique ability, hummingbirds may reach speeds of 25 to 30 mph as they go. These birds have flexible wings that they can rotate in swift circles to help fly in reverse.
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.
