By Jonathan Corum Nov. 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. Add a Comment. View More Comments.

Guard 2: Oh yeah, I agree with that. King Arthur: [exasperated] Will you ask your master if he wants to join my court at Camelot?! Guard: indcredulous What, a swallow, carrying a coconut? Arthur: It could grip it by the husk! Two swallows carrying one coconut would each have to flap their wings at This is given as evidence that the bird could not, in fact, carry a 1-pound coconut.
Coconuts cannot migrate. However, they can be carried by certain species of swallow to climates that normally would be unable to grow palm trees. Adventurers, kings, or persons with a holy mandate will often take advantage of this fact by employing a lackey to emulate a horse using said coconut halves.
The Portuguese carried coconuts from the Indian Ocean to the West Coast of Africa, Olsen says, and the plantations established there were a source of material that made it into the Caribbean and also to coastal Brazil.

If they didn't know the answer, then they were plunged into the pit below. If you are having trouble remembering, be sure to watch the short clip above of the comedic scene. In the same scene, the question is posed of whether this refers to an African or a European swallow. We'll have to take this into account when we do our math later, too.
The discussion also includes the question of how two halves of a coconut ended up in Europe, with the proposition that a swallow carried a coconut from the tropics. Take a look at the clip below to refresh your memory of that.
First, we need to determine which bird to examine as best fits for those discussed in the movie. 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.
