Caption
Silhouette of the head of a Grey-headed Flying-fox (Pteropus poliocephalus) through its wings. On hot days when resting in trees, flying-foxes will spread their highly vascular wings, thereby allowing more air to flow over them and so helping them cool down. Yarra Bend Park, Kew, Victoria, Australia.
