List of birds by flight speed
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.
Aerial locomotion in marine animals
Jet propulsion generates thrust and momentum by shooting out water jets. Flying squid is known for their behavior of leaping out of the water. Ommastrephinae and Todarodinae are two subfamilies of squids under the family of Ommastrephidae. They utilize jet propulsion to jump out of water as they do underwater, including Japanese flying squid.., Humboldt squid, Neon flying squid, sevenstar flying squid, and Wellington flying squid. Squid flight may be thought to reduce the cost of migration. The acceleration of Sthenoteuthis pteropus in air is 265 body lengths/s (24.5 m/s), which is found to exceed that in water (79 body lengths/s).
