These birds spend almost their entire lives in flight, only stopping to breed in narrow cracks high up in buildings. With sickle-shaped wings and superpowered claws, they eat, sleep, and even drink on the wing. Keep your eyes (and ears) open this summer – those screaming black shapes overhead? They're Swifts in action! 🐦💨 Footage by Nicholas Galea, Aron Tanti , James Aquilina, Noel Camilleri, Mario V Gauci and Mike Wilson.
