What did falcons hunt?
A falcon is any one of the types of hawks in the family Falconidae, and especially the ones in the genus Falco, which includes the "true" falcons such as Merlins, American Kestrels, Peregrine Falcons, Gyrfalcons and Prairie Falcons. These birds have long, pointed wings, long tails and short notched, curved bills. They are swift, powerful fliers that hunt prey for themselves. Some of them, especially the female Peregrine Falcons, are trained by falconers to hunt…
Falconers were people who used falcons to hunt. They could be grouped into the people who owned falcons and the land they hunted on, and the servants who were very skilled with falcons, and were employed by the lords for that purpose. In either case, they ate food suitable to the members of their class.
falcons hunt by flying high on the thermals (hot air pockets of air that travel up) and using their excellent eyesight would spot small animals on the ground below and they would go into a stoop (when they fold their wings back and gain lots of speed) and at the last moment they would open their wings and hit the animal usually killing it instantly.
Peregrine falcons are carnivores, meaning they eat meat. Peregrine falcons hunt for food in the air and attach their claws to a bird in flight, or otherwise overwhelm their prey. Their main food sources are other birds. From Wikipedia: "The Peregrine is renowned for its speed, reaching speeds of over 320 km/h (200 mph) during its characteristic hunting stoop, making it the fastest extant member of the animal kingdom."
