The bird that can achieve the greatest airspeed is the peregrine falcon (Falco peregrinus), able to exceed 320 km/h (200 mph) in its dives. [1] [2] A close relative of the common swift, the white-throated needletail (Hirundapus caudacutus), is commonly reported as the fastest bird in level flight with a reported top speed of 169 km/h (105 mph ...
Hummingbird flight is different from other bird flight in that the wing is extended throughout the whole stroke, which is a symmetrical figure of eight, [17] with the wing producing lift on both the up- and down-stroke. [12] [13] Hummingbirds beat their wings at some 43 times per second, [18] while others may be as high as 80 times per second. [19]
The Monarch Butterfly has a very low 0.168 kg/m 2 wing loading The McDonnell Douglas MD-11 has a high 837 kg/m 2 maximum wing loading. In aerodynamics, wing loading is the total weight of an aircraft or flying animal divided by the area of its wing.
A study testing the flight physics of an "ideal falcon" found a theoretical speed limit at 400 km/h (250 mph) for low-altitude flight and 625 km/h (388 mph) for high-altitude flight. [61] In 2005, Ken Franklin recorded a falcon stooping at a top speed of 389 km/h (242 mph).
Swifts are among the fastest of birds in level flight, and larger species like the white-throated needletail have been reported travelling at up to 169 km/h (105 mph). [7] Even the common swift can cruise at a maximum speed of 31 metres per second (112 km/h; 70 mph).
This height was recorded over Nevada; [1] [4] [5] This record occurred when a Lockheed L-188 Electra turboprop airliner operating a Western Airlines flight suffered a bird strike at cruising altitude. [8] Bar-tailed godwit: Limosa lapponica: Scolopacidae: 6,000 metres (20,000 feet) [5] [9] It can reach this height while migrating. White stork ...
Birds (flying, soaring) – Most of the approximately 10,000 living species can fly (flightless birds are the exception). Bird flight is one of the most studied forms of aerial locomotion in animals. See List of soaring birds for birds that can soar as well as fly. Townsends's big-eared bat, (Corynorhinus townsendii) displaying the "hand wing"
Dynamic soaring is used predominately by birds, and some model aircraft, though it has also been achieved on rare occasions by piloted aircraft. [32] Examples of soaring flight by birds are the use of: Thermals and convergences by raptors such as vultures; Ridge lift by gulls near cliffs; Wave lift by migrating birds [33]
