The Brown Falcon (Falco berigora), also known as the Brown Hawk, is a member of the falcon genus found in the drier regions of Australia. Its specific name berigora is derived from an aboriginal name for the bird.
The flight and hunting methods of the brown falcon differ markedly from those of other falcons. Both its wing-beats and flight are relatively slow. It is usually seen quietly perched or flying, alternatively beating its wings and gliding with wings held in a shallow "V" position. It sometimes hovers rather inefficiently, especially on windy days, but it has the ability to soar to great heights.
Adults are usually 10 cm to 20 cm long. They are found in light and dark forms and a variety of intermediates. Animals typically have red-brown heads with narrow black streaks with a light crown and off white chin. Wings are a spotted red-brown with dark brown quills. Beaks are light blue/grey, eyes are brown. The falcons make a loud cackle call uttered frequently.
Brown falcons breed from June - November usually in an old nest of another hawk species, they occasionally nest in hollow limbs of trees. The brown falcon lays between 2-5 eggs that have red and brown spots and blotches.
