The establishment and dynamics of a recently established urban camp of flying foxes (Pteropus poliocephalus) outside their geographic range

Abstract

Grey-headed flying foxes Pteropus poliocephalus (Megachiroptera: Pteropodidae), listed nationally in Australia as vulnerable, have been recorded infrequently in low numbers in Melbourne from the first record of the species in 1884 till the early 1980s.
