Description

The information in this section is based on recent descriptions by several authors (notably, Debus & Davies 2012, Debus & Olsen 2011, Morcombe 2002 and Birds in Backyards n.d.). Size (adult, beak to tail): 45 – 56 cm (average 50 cm), tail makes up about half the length. Note: Females are larger than males - this is a form of sexual dimorphism. Average weight: 833 g (female) 582 g (male). Wing span: 95 –115 cm. Colouration is uniform dark brown to sooty black; juveniles are generally darker than adults; underwing feathers are two-tone (flight feathers slightly paler); adults may have an evident dark stripe below the eye. Occasionally the birds may have a white chin, spots on underwing coverts or bars on undertail coverts. Cere, eye ring and feet are pale grey (or pale blue-grey); eye is dark brown and beak tip is black. Talons are black. Chick is white down. The falcon's body is streamlined with a relatively long tail and slim build. Wings are long and pointed tapering toward wing tip.

Feeding Habits
Black Falcon predominantly feeds on a variety of birds, from small finches to larger cockatoos, as well as small mammals like rabbits. Its diet also includes insects and carrion. Black Falcon's hunting techniques are adapted for aerial pursuit, and it occasionally fails to capture agile prey such as parrots.
Habitat
The black Falcon primarily inhabits a range of open and semi-open landscapes including sparse eucalyptus woodlands, savannas, scrubby grasslands, and farmlands. These areas are typically situated near watercourses or wetlands within arid regions, providing the black Falcon with suitable nesting sites in woodland areas and isolated trees.

General Info

Feeding Habits

Bird food type

Behavior

The black falcon is known to both harass and be harassed by other bird species, including raptors and corvids. It may be found resting on power poles during the day but will not sit on wires.

Distribution Area

The species’ home range is undetermined, but likely to be greater than 100 km. The species appears to be wide-ranging in the non-breeding season, but is also known to stay in regular non-breeding territories for lengthy periods.

Species Status

The black falcon is listed by the IUCN as least concern. It is generally considered scarce, uncommon and nomadic but has at least one stronghold in inland Queensland. It is listed as Vulnerable in NSW and Victoria. In 2009 BirdLife International estimated the black falcon's population as between 670 and 6700 mature individuals, with a stable population trend.
