There are 47 species of swallow native to Africa.  Of those, only two are actually named for the continent:  the West African Swallow (Hirundo domicella) and the South African Swallow (Hirundo spilodera).\n\nThe South African Swallow's range only extends as far north as Zaire, and thus it is probably the non-migratory bird often mentioned in these comparisons.\n\nThe European Swallow (Hirundo rustica) must beat its wings 18 times per second to remain airborne (not 43 as is popularly believed).  Comparing this with the average amplitude of their wing beat we come out to an average airspeed of about 11 meters per second (approximately 24 miles an hour).\n\nThis is cruising speed, mind you.  It's possible that the birds could as much as double that for top speed.\n\nThe South African Swallow is slightly more massive than the European Swallow, however it's wing is also correspondigly larger.  Although biometric data on the species is hard to come across, and not easily electronically accessible, it is reasonable to assume that this species has much the same unladen air velocity as the European species.  That is, about 11 meters per second.

Bumblebees can fly. On an average, a bumblebee travels at a rate of 3 meters per second, beating its wings 130 times per second.\n\nHow did this business of proving that a bumblebee can't fly originate? Who started the story?\n\nOne set of accounts suggests that the story first surfaced in Germany in the 1930s. One evening at dinner, a prominent aerodynamicist happened to be talking to a biologist, who asked about the flight of bees. To answer the biologist's query, the engineer did a quick "back-of-the-napkin" calculation.\n\nTo keep things simple, he assumed a rigid, smooth wing, estimated the bee's weight and wing area, and calculated the lift generated by the wing. Not surprisingly, there was insufficient lift. That was about all he could do at a dinner party. The detailed calculations had to wait. To the biologist, however, the aerodynamicist's initial failure was sufficient evidence of the superiority of nature to mere engineering. \n\nWhatever its origins, the story has had remarkable staying power, and the myth persists that science says a bumblebee can't fly. Indeed, this myth has taken on a new life of its own as a piece of "urban folklore" on the Internet.\n\nIn some sense, the story has done its share to inspire further research. In recent years, scientists have tackled the problem of insect flight from a number of different angles and gained new insights into the complexities of powered flight. \n\nIt's quite possible, for instance, to calculate correctly the area of a rectangular piece of property just by multiplying the length times the width. Yet you can still get the "wrong answer" from a practical point of view, maybe because the measurements of the length and width were inaccurate or there was some ambiguity about the plot's boundaries or shape.\n\nSo, no one "proved" that a bumblebee can't fly. What was shown was that a certain simple mathematical model wasn't adequate or appropriate for describing the flight of a bumblebee.\n\nInsect flight and wing movements can be quite complicated. Wings aren't rigid. They bend and twist. Stroke angles change. New, improved models take that into account.

The altitude record is held by a Rüppell's griffon Gyps rueppelli, a vulture with a 10-foot wingspan. On November 29, 1975 one was sucked into a jet engine 37,900 feet above the Ivory Coast in West Africa. The plane was damaged but landed safely. What the bird was doing up so high I have no idea, since this species is not migratory.\n\nThe bird that flies highest most regularly is the bar-headed goose Anser indicus, which travels directly over the Himalayas en route between its nesting grounds in Tibet and winter quarters in India. They are sometimes seen flying well above the peak of Mt. Everest at 29,035 ft. Birds have some natural advantages for getting oxygen at high altitudes, in particular an arrangement of air sacs that allows them to circulate inhaled air twice through the lungs with each breath--much more efficient than the in-and-out system used by mammals. Bar-headed geese have special adaptations that make them even better at high-flying than other birds. They have a special type of hemoglobin that absorbs oxygen very quickly at high altitudes, and their capillaries penetrate especially deep within their muscles to transfer oxygen to the muscle fibers.\n\nOther high flying birds include whooper swans, once observed by a pilot at 27,000 feet over the Atlantic between Iceland and Europe, and bar-tailed godwits (a shorebird), which have been seen at almost 20,000 feet. The record for North America is a mallard duck that collided with an airplane at 21,000 feet above Elko, Nevada in July, 1963. Most birds, though, fly lower--waterfowl typically at between 200-4,000 feet, and small songbirds at between 500-2,000 feet. However, the tiny Blackpoll warbler will fly up to 16,000 feet high in order to catch favorable winds on migration between Canada and South America. I'm not sure how well a sparrow would do, but similar-sized birds are quite capable of flying very high indeed.

Lizz –\nMost kites are designed for a specific range of wind velocities.  If your kite doesn’t list a range, then it usual default is 5 to 15 mph, especially for diamond shaped (the kind with a tail) or delta wing types.  Box kites need more wind.\nOnly the lightest kites and best flyers can usually get a kite up in a 2 mph wind.  I have flown kites in ranges from 2 to perhaps 35 mph.\nFor 5 mph (steady, with gusts up to 10 mph) most novices can get one up and keep it flying.\n7 mph is usually very easy, 10 isn’t bad.\nSimple kites have a single location to fix the kite string to the kite.  Better kites have ways of adjusting the “bridle” which changes the “tilt” of the kite toward the wind.  This allows them to be flown in a wider range of wind speeds.\nAll of the speeds mentioned above are “ground speeds,” that is the velocity of the wind at ground level.  Keep in mind that the weather report wind speeds are usually not recorded at ground level, so take them as a rough guide.  Also be aware that depending upon where you fly the kite, the difference in velocity only 100 feet up can make a real difference.  Some kites might be hard to get off the ground, but then soar like crazy once they get up.  You will need to experiment.

Something's wrong with the writeup for the first question.  I'm guessing it should have said THR = RHR + 0.65(MHR-RHR), because otherwise you're gonna get a THR of, like, 10000 beats per minute.\n\nProceeding from that assumption, the THR is RHR + 0.65(MHR-RHR).  You're told that the RHR is 54 bpm.  The MHR is 220 - the age(43), so it's 177.  Therefore the THR is 54 + 0.65(177-54) = 54 + 0.65(123) = 54 + 79.95 = 133.95 bpm.\n\nIn the second question, you didn't provide the "following equations," but think of it this way.  The airplane flew for a total of 15 hours at an average speed of 350 miles per hour.  That means it went 5250 miles.  In the final 7 hours it went 2275 miles.  So in the first 8 hours it had to go 2975 miles.  2975 miles/8 hours = 371.875 mph.  I don't exactly know how to write that in an equation, but now that you understand the reasoning, hopefully you'll be able to recognize the correct equation.  If all else fails, plug the data into each equation and see which one returns 371.875.

The highest fllying recorded so for is - a griffon. See below more details:\nthe mid 1980's was a Ruppell's griffon, an African vulture, struck by an airliner at 37,000 feet.\nAnother vulture, a lammergeyer was seen over "its mountain home" at 25,000 feet over Mt. Everest; alpine choughs have been recorded nesting at 27,000 feet on Mt. Everest. A mallard was struck by an airliner at 21,000 feet over Nevada. Records of smaller birds, also from hitting airplanes, are mostly\nfrom 7,000 to 12,000 feet. See Terres, Audubon Society Encyclopedia of North American Birds.\nVR

What do you mean, an African or European Swallow?\nIn order to maintain air speed velocity a swallow needs to beat its wings 43 times every second, right?\n\nActually, the correct answer appears to be the average cruising airspeed velocity of an unladen European Swallow is roughly 11 meters per second, or 24 miles an hour.

Yoki is right on.  Some birds that normally summer in northern Canada do not go very far south at all.  Juncos and tree sparrows, two birds of the far north like to winter in the northern U S. And of course some do not migrate at all.  Normally, birds whose food supply consist of insects and fruit and flowers are the migrators. But as Yoki pointed out the Artic Tern, a fish eater, is one of the worlds longest migrators. Some Artic Terns do not make it all the way to the Artic however. There is a large colony that breed on a small island off the coast of Maine.
