What is the airspeed of an unladen swallow?
To begin with, I need basic kinematic data on African and European swallow species.
South African Swallow (Hirundo spilodera)
European Swallow (Hirundo rustica)
Although 47 of the 74 worldwide swallow species are found in Africa, only two species are named after the continent: the West African Swallow (Hirundo domicella) and the South African Swallow (Hirundo spilodera), also known as the South African Cave Swallow.
