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.

*Based upon published species-wide averages of wing length and body mass, initial Strouhal estimates based on those averages and cross-species comparisons, the Lund wind tunnel study of birds flying at a range of speeds, and revised Strouhal numbers based on that study gives an estimate that the average cruising airspeed velocity of an unladen European Swallow is roughly 11 meters per second, or 24 miles per hour.

What is the forward velocity of a laden swallow and how does this compare to the unladen swallow of Monty Python fame?

An unladen swallow may fly at around 11meters per second, but common sense suggests that if the swallow is carrying extra mass (i.e. is laden, and not too heavily) it will hav

What is the average airspeed of a swallow?

Ah, a wonderful question, no doubt from monti python ik den holi grale. Put simply, if it is a european swallow it will be 7,299 km per sq foot. If it is an african swallow it
