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 '''brown falcon''' ('''''Falco berigora''''') is a relatively large [[falcon]] native to [[Australia]] and [[New Guinea]].


A number of [[plumage]] morphs occur, with the primary distinction being between the pale morph and the dark morph. Both morphs usually have dark brown upper parts and wing [[covert feather|coverts]]. Dark morph birds have predominantly dark under parts, although some light streaking is common. Pale morph birds have white underparts that are varyingly streaked with brown, sometimes heavily so. Pale individuals may also have prominently white under tail coverts and these may be diagnostic. A distinctive aspect of their behaviour is shown in the breeding season when brown falcons make a loud, high pitched, cackle call (like a laying hen) and screeching while in flight.<ref>{{Cite web|url=http://www.wiresnr.org/BrownFalcon.html|title=Brown Falcon|archive-url=https://web.archive.org/web/20210831022923/http://www.wiresnr.org/BrownFalcon.html|archive-date=August 31, 2021}}</ref>
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.


The [[species]] name ''berigora'' has Aboriginal origins.
The brown falcon does not hunt by chasing its prey in flight. Its main method of searching for its food is to sit quietly on a high perch such as a dead branch on a tree or power pole. It drops down on its prey and grabs it with its talons. The falcon also searches for prey whilst gliding and flying.

A brown falcon used for falconry in Tasmania

The brown falcon (Falco berigora) is a relatively large falcon native to Australia and New Guinea.

A number of plumage morphs occur, with the primary distinction being between the pale morph and the dark morph. Both morphs usually have dark brown upper parts and wing coverts. Dark morph birds have predominantly dark under parts, although some light streaking is common. Pale morph birds have white underparts that are varyingly streaked with brown, sometimes heavily so. Pale individuals may also have prominently white under tail coverts and these may be diagnostic. A distinctive aspect of their behaviour is shown in the breeding season when brown falcons make a loud, high pitched, cackle call (like a laying hen) and screeching while in flight.[2]

The species name berigora has Aboriginal origins.

Description

Adults are usually 40 to 50 cm (16 to 20 in) 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.

Breeding and habitat

Brown falcons breed from June to November, usually in an old nest of a larger passerine or another hawk species; they occasionally nest in hollow limbs of trees. The brown falcon lays between two and five eggs that have red and brown spots and blotches.

Subspecies

  • F. b. novaeguineae : central and eastern New Guinea and coastal northern Australia[3]
  • F. b. berigora : Australia (except coastal north) and Tasmania

Diet

The brown falcon eats small mammals, including house mice. They also eat young rabbits in the summer. It also eats small birds, lizards, snakes, and a variety of invertebrates, particularly caterpillars, grasshoppers, crickets, and beetles. Insects form the bulk of the animals' diets during winter and the falcons often chase the insects on the ground.

Behaviour

Brown falcons and other Australian firehawks have been said to pick up sticks with flames and dropping them to spread fires and prey on escaping animals.[4] According to Audubon, "That anecdotal evidence is sourced from personal testimonies by Australian firefighters and aboriginal people, as well as historical literature, and amounts to 14 firsthand narratives of this specific occurrence."[5][6]
