The grey-headed flying fox (Pteropus poliocephalus Temminck) is a threatened large fruit bat endemic to Australia. It roosts in large colonies in rainforest patches, mangroves, open forest, riparian woodland and, as native habitat is reduced, increasingly in vegetation within urban environments. The general biology, ecology and behaviour of this bat remain largely unknown, which makes it difficult to effectively monitor, protect and manage this species. The current study provides baseline information on the daytime behaviour of P. poliocephalus in an autumn/winter roost in urban Sydney, Australia, between April and August 2003. The most common daytime behaviours expressed by the flying foxes were sleeping (most common), grooming, mating/courtship, and wing spreading (least common). Behaviours differed significantly between times of day and seasons (autumn and winter). Active behaviours (i.e., grooming, mating/courtship, wing spreading) occurred mainly in the morning, while sleeping predominated in the afternoon. Mating/courtship and wing spreading were significantly higher in April (reproductive period) than in winter (non-reproductive period). Grooming was the only behaviour that showed no significant variation between sample periods. These results provide important baseline data for future comparative studies on the behaviours of flying foxes from urban and ?natural? camps, and the development of management strategies for this species.

The maintenance energy (MER) and nitrogen (MNR) requirements of Pteropus poliocephalus were determined from a series of feeding trials with artificial diets. The low basal metabolic rate (BMR: 225 kJ.kg-0.75.d-') of this bat is associated with a low MNR (457 mg. kg-0.75.d-') but does not reflect a low MER (667 kJ.kg-0.75.d-'). From flight data of Carpenter and the MER from this study, a minimal field energy budget was calculated to be 944 kJ. .d-'. This value is high compared to that of microchiropteran bats. Studies of the digestibility of two fruit diets, native fig and apple, showed that more energy than nitrogen was apparently absorbed. The latter is a limiting nutrient in the apple diet, so that 3.2 times as much dry matter must be consumed in order to meet the nitrogen requirement as for the field energy requirement. It is postulated that the low BMR and low MNR are associated with an interrupted or restricted source of dietary nitrogen. A high MER may provide a means by which surplus energy is dissipated as heat. An ititake of excess energy in order to meet nitrogen requirements also explains how P. poliocephalus can afford a high field energy budget.
