Behaviour: Birds category. The Incubator Bird by Gerry Pearce, UK/Australia. Most birds incubate their eggs with their bodies. Not so the Australian brush turkey, one of a handful of birds – the megapodes – that do it with an oven. Only the males oversee incubation. In this case, a male had chosen to create his nest-mound near Gerry’s home in Sydney, bordering Garigal national park. If he and his mound were to females’ liking, they would lay a clutch of eggs inside. In this picture, he is piling on more insulation to raise the temperature.
