There is, in fact, a European swallow, but there is no swallow specifically named the African Swallow. However, there is a South African swallow and a West African swallow, which may be good fits when discussing an African swallow. However, there is almost no data recorded that can give us an indication of the airspeed of either type of African swallow. Rather than make blind guesses about African swallow, it may be better to look into the capabilities of the European, or Barn, swallow, for which there is.
According to research from the Avian Demography Unit of the University of Capetown, the European swallow has an average length of If we use the information mentioned in the videos above, we would estimate that a European swallow flaps its wings 43 times every second in order to maintain the necessary airspeed velocity.
Examining research by zoologist C. Pennycuick, in a journal article entitled Predicting Wingbeat Frequency and Wavelength of Birds , we can find relevant data to the European swallow. This gram swallow was found to flap its wings about 12 times every second, with an amplitude of 20 cm each time. Strike one for Monty Python. Though, I guess we can give them a little bit of credit here, considering that the swallow being observed in this research wasn't exactly what King Arthur was talking about.
Ben Davis March 29, What is the average speed of an unladen swallow Monty Python quote? What is the African Swallow quote from Monty Python? What are the three questions asked in Monty Python? Can an African swallow carry a coconut? Can two swallows carry a coconut?
Could a European swallow carry a coconut? What are the monks saying in Monty Python? What is the velocity of a swallow? Are coconuts migratory? How did coconuts get to the Caribbean? What is the airspeed velocity of an unladen swallow GIF? What is the airspeed velocity of an unladen Spaghetti Monster? Where is pastafarianism practiced? What do you mean, an African or European Swallow? To begin with, I needed basic kinematic data on African and European swallow species.
In order to maintain airspeed velocity, a swallow needs to beat its wings forty-three times every second, right? Downy Woodpecker 27 g 14 Hz 29 cm Budgerigar 34 g 14 Hz 15 cm Note that even the tiny Zebra Finch flaps its wings no more than 27 times a second while cruising.
Downy Woodpecker 31 cm 14 Hz 29 cm European Starling 35 cm 14 Hz 26 cm By averaging all 6 values, we can estimate that an average European Swallow flies at cruising speed with a frequency of roughly 15 beats per second, and an amplitude of roughly 22 cm. If we settle on an intermediate Strouhal value of 0. Three shall be the number thou shalt count Airspeed can also be predicted using a published formula. Oh, yeah, I agree with that With some further study, it became clear that these estimates are accurate, though perhaps coincidental.
