Species Description
The Chestnut-quilled Rock Pigeon (*Petrophassa rufipennis*) is a plump, dark pigeon found only in the rugged sandstone escarpments of Arnhem Land and Kak in Australia’s Northern Territory. This species is endemic to the region and is most often detected by the distinctive clattering of its wings as it takes flight from rocky ledges.
Fun Facts
This species can tolerate extreme heat, surviving in rock crevices where temperatures can exceed 5°C by remaining inactive during the hottest parts of the day.
1. Bright chestnut wing patch visible in flight
2. Loud wing-clattering sound on takeoff
3. Plump body with drooping wings when perched
These pigeons are highly adapted to their rocky environment, feeding mainly on seeds found among spinifex and sparse woodland vegetation. They prefer walking and running among rocks, only flying when disturbed, and rarely perch in trees. Breeding occurs in the dry season, with most observed nests occurring in May-November when food and water are concentrated around permanent sources. A sturdy nest is made from sticks, leaves, and grass, usually hidden on a shaded rocky ledge or in a crevice. Both parents help make the nest. They lay two creamy white eggs. Young pigeons leave the nest when they are about 2 to 3 weeks old and begin growing their adult feathers at around five months.
Restricted to the sandstone escarpments and gorges of western Arnhem Land and Kakadu National Park, the Chestnut-quilled Rock Pigeon is typically seen roosting on high rocky cliffs or sandstone towers. They descend to sandy or grassy ground at dawn and dusk to feed, making these times best for observation. Listen for their noisy wingbeats, which often reveal their presence before they are seen.
