Came here to say something similar. Common swifts are amazing. Quoting Wikipedia: > Except when nesting, swifts spend their lives in the air, living on the insects caught in flight; they drink, feed, and often mate and sleep on the wing. Some individuals go 10 months without landing. No other bird spends as much of its life in flight. Contrary to common belief, swifts can take flight from level ground. Their maximum horizontal flying speed is 111.6 km/h. Over a lifetime they can cover millions of kilometers.
