Description General Info
Description
The white-quilled rock pigeon is a large mid-brown to reddish-brown pigeon. It has wings measuring 122 to 145 mm and a bill 11.0 to 14.5 mm in length. Subspecies albipennis weighs 117 to 156 grams while the smaller subspecies boothi weighs between 103 to 142 grams. It has white spots on its chin and forehead. The orbital skin is grey. Although their common name derives from the white wing panels visible in flight, its facial markings are also distinctive. There are thin, pale lines "across the face, from the base of upper mandible curving above and behind eye, and from lower mandible below eye and curving across sides of head." Subspecies albipennis, found mostly in WA, has large white patches on its wings while subspecies boothi, found in the NT, has smaller patches.

Behavior
The IUCN Red List identifies the pigeon's conservation status as Least Concern (LC) but its Northern Territory Conservation Status is listed as Near Threatened (NT). The pigeon's habitat is rocky escarpments and gorges where they move easily among the rocks and boulders. They share a distinctive jizz with the chestnut-quilled rock pigeon, often appearing on a prominent rock or ledge with their body held horizontally, their tail held clear of the ground and their wings drooping below their tail. The white-quilled rock pigeon's defining characteristics were first recorded when the type specimens were collected by officers of HMS Beagle and detailed in an account of his Australian voyages of the Beagle by her commander, John Lort Stokes: They fly with a characteristic loud clattering of wings, often gliding from one high prominence to another. They feed in adjacent grassy woodlands but return to their escarpments when startled.
