The spinifex pigeon (Geophaps plumifera) is a bird in the pigeon family, Columbidae. It is endemic to Australia, occurring throughout much of the arid and semi-arid northern and central parts of the continent. It lives in stony habitats on rocky hills and mountainous terrain, gorges, dry rocky creek beds and nearby gibber plains. The spinifex pigeon weighs 80 to 110 grams (2.8 to 3.9 ounces), with a mean body length of 200 to 235 millimetres (7.9 to 9.3 inches) and a wingspan of 300 to 350 millimetres (12 to 14 inches). Its plumage is distinctively rufous-brown with thin black bars on the wings and back. The forehead, the sides of the crown and the ear coverts are grey, while the bill is black, and it has distinctive facial markings including a bright red facial mask and a white band extending from the chin to behind the eye. This spinifex pigeon was photographed in Watarrka National Park in Australia's Northern Territory.Photograph credit: John Harrison
