About this episode
Hummingbirds are built for hovering flight, with flexible wrists that rotate their wings in a rapid figure-eight motion that generates almost constant lift. Eurasian Skylarks, on the other hand, hover by fluttering their wings 10-12 times per second, singing all the while. Some raptors such as American Kestrels use a different strategy: by flying into the wind, they can float in place while they scan for prey.
