Grey Falcon

The Grey Falcon is among Australia's rarest raptors, confined to the driest parts of the continent's interior where it hunts over vast open plains and sparse woodland. Its pale, almost ghostly grey and white plumage sets it apart from every other Australian falcon and most falcons worldwide.

Given its low population and remote range, feather finds are uncommon, but the extremely pale, lightly marked plumage is highly distinctive when encountered.

Recognizing Grey Falcon feathers

• Flight feathers: Pale blue-grey above with faint darker barring, contrasting with whitish underwing.
• Tail feathers: Pale grey with narrow, subtle dark banding.
• Body feathers: Back and crown feathers soft pale grey; underside feathers whitish with fine grey streaking, notably paler than any other Australian falcon.
• Shaft color: Pale grey.
• Compared to similar species: Much paler overall than the Black Falcon, Brown Falcon, or Australian Hobby; the near-white underside with only fine streaking is unmatched among Australian raptors.

Adults are pale blue-grey above and whitish below with fine grey streaking, giving an overall soft, pale appearance unlike any other falcon in its range. Sexes are similar, with females larger. Juveniles are slightly browner-grey above with a bit more streaking below, gradually paling toward the adult's very light plumage.

Confined to the arid and semi-arid interior of Australia, particularly around watercourses lined with trees amid open plains and spinifex country. Resident, though often nomadic in response to prey and water availability in its harsh, unpredictable environment.

Hunts birds, especially those visiting watercourses, in fast direct flight, and also takes small mammals and reptiles. Nests in old stick nests, usually in tall trees along inland rivers. Calls include harsh cackling notes near the nest. A pale grey flight feather with only faint barring, found near an arid-zone watercourse in central Australia, would be a notable and rare find pointing to this species.
