Native to the United States and Canada this raptor migrates to Argentina during the austral summer. It is opportunistic and feeds on a wide variety of animals. Nevertheless when it is in Argentina its diet reduces mainly to insects such as locusts, crickets, grasshoppers, etc. caught and eaten on the wing.

Always in flight and sometimes very high in the sky they circle or fly past the reserve generally in big groups.
