The Grey Falcon is a vulnerable bird species; the scientific community considers it one of Australia's rarest birds of prey. 

The Grey Falcon is notable for its light-grey plumage, which gives the bird its name. Their wingtips and tail feathers often feature a darker shade of grey. Their beak is blue-grey that lightens at the base, while their feet are a vivid yellow. A small bird, the Grey Falcon usually measures 14-17 inches in length and weighs from 1.2 to 1.6 pounds.

Thanks to its pale grey feathers, this bird can blend into its habitat, primarily in arid and semi-arid regions. Grey falcons live in open habitats with sparse vegetation.

The Grey Falcon is a highly skilled hunter known for its skill and speed. Its diet is diverse and ranges from mammals to reptiles. However, it is particularly noteworthy for its hunting of other birds.
