Premium Content Subscriber only IPSWICH Nature Centre will remain closed this week, with a flying fox colony that has taken up residence at the visitor hot spot increasing in size over the weekend. The centre closed last Friday, with council officers returning to the roost on Monday to reassess the colony. More than 5000 flying foxes make the trees in the Nature Centre their home during migration. There are three species of flying fox roosting in the park: Black flying fox Pteropus Alecto, Grey-headed flying fox Pterpopus poliocephalus and Little red flying fox Pteropus scapulatus. Although only weighing 600g each, little reds roost in tight clumps which causes the branches to break.
