💡 Did you know?
Young Swifts that leave the nest fly continuously for 2–3 years before landing for the first time — they sleep, eat, drink and even mate on the wing
Swifts have extremely small, weak legs (their name "Apus" means "without feet") — they cannot walk and if grounded can only relaunch from a raised surface
