The majority of flying fox species are nocturnal and forage at night. A few island species and subspecies are diurnal, however, hypothesized as a response to a lack of predators. Diurnal taxa include "P. melanotus natalis", the Mauritian flying fox, the Caroline flying fox, "P. p. insularis", and the Seychelles fruit bat. Foraging resources are often far from roosts, with individuals traveling up to to reach them. Flying foxes can travel at for three hours or more, and can reach top speeds of . Some colonial species will forage in groups, especially when resources are abundant. Less social species will forage alone. When they land on a tree with food, they will hang onto the branch with their clawed hind feet and use their clawed thumbs to pull branches bearing flowers or fruits towards them. As they forage on fruit, flying foxes will compress the fruit against the palate with the tongue to squeeze out and consume the juices. The rest of the fruit is then discarded in "ejecta pellets."
