To record the numbers of flying-foxes using the Gordon site over a 62 month period and report the results of the examination of droppings obtained at the site, in order to test for correlations between colony usage, diet and reproductive events.
Type of Study:
The Gordon site was occupied by substantial numbers of flying-foxes throughout the entire period of 62 months from 1985 to 1990. As a result of the introduction of plants native to other parts of Australia and exotics from other continents, there is a variety of foods available throughout the year in the Sydney region, in comparison with less urbanized areas. This food supply permits the occupation of the Gordon colony site during winter and spring and reduces the migratory behaviour of flying-foxes throughout the year. The use of any food by flying-foxes from the Gordon site is probably linked to its attractiveness and availability, but not necessarily to its abundance, as even an abundant food supply may not be available to an animal.
