About Falco berigora Vigors & Horsfield, 1827
Adults of Falco berigora (brown falcon) are usually 40 to 50 cm (16 to 20 in) long. This species occurs in distinct light and dark colour forms, plus a range of intermediate forms. Individuals typically have red-brown heads marked with narrow black streaks, a light crown, and an off-white chin. Their wings are spotted red-brown with dark brown quills. Beaks are light blue-grey, and eyes are brown. Brown falcons frequently make a loud cackling call. Brown falcons breed from June to November. They usually nest in an old nest built by a larger passerine bird or another hawk species, and occasionally nest in hollow tree limbs. The brown falcon lays between two and five eggs per clutch, and the eggs have red and brown spots and blotches.
