A â 0.22 (meters per beat) U â 3*15*0.22 â 9.9. ... to estimate that the airspeed velocity of an unladen European Swallow is 10 meters per second. With some further study, it became clear that these estimates are accurate, though perhaps coincidental.
Compare that to baby robins, which fledge when they are 14-16 days old and weigh over 50 grams! Swallows don't nest in trees. A swallow builds its nest on a barn rafter, bridge overhang, or other structure well off the ground. If a baby swallow doesn't make a strong first flight, it will crash on the ground. In order to survive this first flight, a swallow fledgling must have strong wings. That's why it starts exercising, flapping its little wings hard, by the time it's 9 days old.
