A rehabilitation grey-headed Flying fox returns to the wild after being released by wildlife carers at a bat colony in western Sydney, Australia, Sunday, March 13, 2011. A natural food shortage caused by rains, flooding and cyclones has forced flying foxes who normally feed on pollens and nectars into suburban gardens. A large number of grey-headed Flying foxes, an endangered species, have needed to be rescued from city regions after being entangled in fruit tree netting used by residents in a bid to stop the starving bats from feeding in them.
