The grey-headed flying fox was the first Australian flying fox species discovered by Europeans. The first grey-headed flying fox specimen was reported as collected in New Holland and described by Temminck in 1825. Their numbers have declined drastically since European colonisation from many millions to a few hundred thousand. The known range for grey-headed flying foxes has contracted southwards by about 750 km and their southern limit during winter has expanded into Victoria. They are the largest Australian fruit bat and are endemic to Australia. Grey-headed flying foxes have sophisticated vocal communication, making more than 30 specific calls.
Fascinating grey-headed flying fox facts
Grey-headed flying foxes in NSW have a diverse diet comprising at least 54 flower species (nectar and pollen), and 48 fruit species from subtropical rainforest. They mostly eat nectar and pollen from eucalypt woodlands and forests, but some individuals eat mainly blossom and others select mainly fruit.
Some Greys stay permanently in one camp; others will travel widely between camps to feed on irregularly flowering eucalypts. Two young adult males tracked over 10 months made round trips of at least 2000 km, transiting 6–15 camps.
