<P> 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 gliding . The bird with the greatest airspeed velocity is the Peregrine falcon, able to exceed 321.8 km / h (200 mph) in its hunting dives . The greatest self - powered horizontal speed is achieved by Homing Racing Pigeons . They can fly 1100 km (700 miles) in a single day, and they have been recorded flying at 177 km / h (110 miles per hour), making them the birds with the fastest speed ever recorded on a self - powered flight, and the fastest endurance flight . </P> <Table> <Tr> <Th> Common name </Th> <Th> Image </Th> <Th> Species </Th> <Th> Family </Th> <Th> Average horizontal speed </Th> <Th> Maximum horizontal speed </Th> <Th> Average diving speed </Th> <Th> Maximum airspeed </Th> <Th> Flight </Th> </Tr> <Tr> <Td> Peregrine falcon </Td> <Td> </Td> <Td> Falco peregrinus </Td> <Td> Falconidae </Td> <Td> 65--90 km / h 40 - 56 mph </Td> <Td> 110 km / h 68 mph </Td> <Td> 320 km / h (200 mph) </Td> <Td> 389 km / h 242 mph </Td> <Td> High - speed dive--pointed long wings </Td> </Tr> <Tr> <Td> Golden eagle </Td> <Td> </Td> <Td> Aquila chrysaetos </Td> <Td> Accipitridae </Td> <Td> 45--51 km / h 28 - 32 mph </Td> <Td> 129 km / h 80 mph </Td> <Td> 241 km / h 150 mph </Td> <Td> 320 km / h 200 mph </Td> <Td> </Td> </Tr> <Tr> <Td> Grey - headed albatross </Td> <Td> </Td> <Td> Thalassarche Chrysostoma </Td> <Td> Diomedeidae </Td> <Td> </Td> <Td> 127 km / h 78.9 mph </Td> <Td> </Td> <Td> </Td> <Td> 2.2 m (7'2 ") wingspan allows for high power use from wind . </Td> </Tr> <Tr> <Td> Gyrfalcon </Td> <Td> </Td> <Td> Falco rusticolus </Td> <Td> Falconidae </Td> <Td> 80--110 km / h 50 - 68 mph </Td> <Td> 145 km / h 90 mph </Td> <Td> 187--209 km / h 116 - 130 mph </Td> <Td> 209 km / h 130 mph </Td> <Td> High - speed dive--pointed long wings </Td> </Tr> <Tr> <Td> White - throated needletail </Td> <Td> </Td> <Td> Hirundapus caudacutus </Td> <Td> Apodidae </Td> <Td> </Td> <Td> 169 km / h <P> 105 mph </P> </Td> <Td> </Td> <Td> 169 km / h <P> 105 mph </P> </Td> <Td> High - speed wings </Td> </Tr> <Tr> <Td> Common swift </Td> <Td> </Td> <Td> Apus apus </Td> <Td> Apodidae </Td> <Td> </Td> <Td> 111.6 km / h <P> 69.3 mph </P> </Td> <Td> </Td> <Td> </Td> <Td> High - speed wings </Td> </Tr> <Tr> <Td> Eurasian hobby </Td> <Td> </Td> <Td> Falco subbuteo </Td> <Td> Falconidae </Td> <Td> </Td> <Td> </Td> <Td> </Td> <Td> </Td> <Td> Can sometimes outfly the swift as it eats them and catches them on the wing . </Td> </Tr> <Tr> <Td> Frigatebird </Td> <Td> </Td> <Td> Fregata </Td> <Td> Fregatidae </Td> <Td> </Td> <Td> </Td> <Td> </Td> <Td> 153km / h </Td> <Td> Slow gliding / soaring high aspect ratio </Td> </Tr> <Tr> <Td> Spur - winged goose </Td> <Td> </Td> <Td> Plectropterus </Td> <Td> Anatidae </Td> <Td> </Td> <Td> </Td> <Td> </Td> <Td> </Td> <Td> High - speed wings </Td> </Tr> <Tr> <Td> Red - breasted merganser </Td> <Td> </Td> <Td> Mergus serrator </Td> <Td> Anatidae </Td> <Td> </Td> <Td> </Td> <Td> </Td> <Td> </Td> <Td> High--aspect ratio wings </Td> </Tr> <Tr> <Td> Canvasback </Td> <Td> </Td> <Td> Aythya valisineria </Td> <Td> Anatidae </Td> <Td> </Td> <Td> </Td> <Td> </Td> <Td> </Td> <Td> High - speed wings </Td> </Tr> <Tr> <Td> Eider </Td> <Td> </Td> <Td> Somateria mollissima </Td> <Td> Anatidae </Td> <Td> </Td> <Td> </Td> <Td> </Td> <Td> </Td> <Td> High - speed wings </Td> </Tr> <Tr> <Td> Teal </Td> <Td> </Td> <Td> Anas crecca </Td> <Td> Anatidae </Td> <Td> </Td> <Td> </Td> <Td> </Td> <Td> </Td> <Td> High--aspect ratio wings </Td> </Tr> </Table>
