It depends on whether you are talking about an African or European swallow. The airspeed velocity of an unladen swallow is roughly 11 meters per second, or 24 miles per hour*, beating its wings 7-9 times per second (rather than 43). But please note that a 5 ounce bird cannot carry a one pound coconut.
