The Grey Falcon, "Falco hypoleucos", is a rare medium-sized falcon, one of the enigmatic ‘mystery’ birds of Australia, neither easily nor predictably seen.

Description

Mainly grey upperparts and white underparts; darker on the tips of the flight feathers; yellow cere. Body length 30-45 cm; wingspan 85-95 cm; weight 350-600 g. Females larger.

Distribution and habitat

The Grey Falcon is an Australian endemic, usually confined to the arid inland. Open country: "Triodia" grassland, "Acacia" shrubland, and lightly timbered arid woodland.

Conservation

It is found at very low densities, numbering only 1,000 breeding pairs, and the population may be stable. Continued high levels of grazing in arid zone rangelands and clearance of the semi-arid zone for marginal farming is degrading habitat.

International

It is considered to be Near Threatened. Listed on CITES Appendix II.

Australia

Grey Falcon are not listed as threatened on the Australian Environment Protection and Biodiversity Conservation Act 1999.
