Why do hawks fly in circles?

Answer by  StingRay (471)

The hawks are looking for food. Hawks have great eyesight go they can see a rabit or even a mouse from quite a distance. Fields are great hunting grounds as they contain food or grain for the prey to feed on. When the mice go to get some food, the hawk is already in position to strike.

Usually that means that there is something in the field that has recently died and they are coming in for the kill. It could be something as small as a mouse or as large as a animal. They have sharp eyes and probably have been watching the attack and waiting for the kill.
