This is a list of the fastest flying birds in the world. A bird's velocity is necessarily variable; a hunting bird will reach much greater speeds while diving to catch prey than when flying horizontally. 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.
Alpine swifts are readily distinguished from the common swifts by their larger size and their white belly and throat. They are around twice as big as most other swifts in their range, about 20 to 23 cm (7.9 to 9.1 in) in length, with a wingspan of 57 cm (22 in) and a weight of around 100 g (3.5 oz). [11]
Swifts occur on all the continents except Antarctica, but not in the far north, in large deserts, or on many oceanic islands. [14] The swifts of temperate regions are strongly migratory and winter in the tropics. Some species can survive short periods of cold weather by entering torpor, a state similar to hibernation. [13]

The white-throated needletail (Hirundapus caudacutus), also known as needle-tailed swift or spine-tailed swift, is a large swift in the genus Hirundapus.It is reputed to reach speeds of up to 170 km/h (105 mph) in horizontal flight, but this is unverified because the methods used to measure its speed have not been published.
The white-throated swift (Aeronautes saxatalis) is a swift of the family Apodidae native to western North America, south to cordilleran western Honduras. [2] Its coastal range extends as far north as Northern California, while inland it has migratory populations found throughout the Great Basin and Rocky Mountain regions, ranging as far north as southern British Columbia.
