TORPY Connell KA, Munro U and Torpy FR, 2006. Daytime behaviour of the grey-headed flying fox Pteropus poliocephalus Temminck (Pteropodidae: Megachiroptera) at an autumn/winter roost. Australian Mammalogy 28: 7-14. 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.

  • Bat Count 2003
    BAT COUNT 2003 Working to promote the long term, sustainable conservation of globally threatened flying foxes in the Philippines, by developing baseline population information, increasing public awareness, and training students and protected area managers in field monitoring techniques. 1 A Terminal Report Submitted by Tammy Mildenstein1, Apolinario B. Cariño2, and Samuel Stier1 1Fish and Wildlife Biology, University of Montana, USA 2Silliman University and Mt. Talinis – Twin Lakes Federation of People’s Organizations, Diputado Extension, Sibulan, Negros Oriental, Philippines Photo by: Juan Pablo Moreiras 2 EXECUTIVE SUMMARY Large flying foxes in insular Southeast Asia are the most threatened of the Old World fruit bats due to deforestation, unregulated hunting, and little conservation commitment from local governments. Despite the fact they are globally endangered and play essential ecological roles in forest regeneration as seed dispersers and pollinators, there have been only a few studies on these bats that provide information useful to their conservation management. Our project aims to promote the conservation of large flying foxes in the Philippines by providing protected area managers with the training and the baseline information necessary to design and implement a long-term management plan for flying foxes. We focused our efforts on the globally endangered Philippine endemics, Acerodon jubatus and Acerodon leucotis, and the bats that commonly roost with them, Pteropus hypomelanus, P. vampyrus lanensis, and P. pumilus which are thought to be declining in the Philippines. Local participation is an integral part of our project. We conducted the first national training workshop on flying fox population counts and conservation at the Subic Bay area.

  • The Philippine Flying Foxes, Acerodon Jubatus and Pteropus Vampyrus Lanensis
    Journal of Mammalogy, 86(4):719- 728, 2005 DIETARY HABITS OF THE WORLD’S LARGEST BATS: THE PHILIPPINE FLYING FOXES, ACERODON JUBATUS AND PTEROPUS VAMPYRUS LANENSIS Sam C. Stier* and Tammy L. M ildenstein College of Forestry and Conservation, University of Montana, Missoula, MT 59802, USA The endemic and endangered golden- crowned flying fox (Acerodon jubatus) coroosts with the much more common and widespread giant Philippine fmit bat (Pteropus vampyrus ianensis) in lowland dipterocarp forests throughout the Philippine Islands. The number of these mixed roost- colonies and the populations of flying foxes in them have declined dramatically in the last century. We used fecal analysis, interviews of bat hunters, and personal observations to describe the dietary habits of both bat species at one of the largest mixed roosts remaining, near Subic Bay, west- central Luzon. Dietary items were deemed “important” if used consistently on a seasonal basis or throughout the year, ubiquitously throughout the population, and if they were of clear nutritional value. Of the 771 droppings examined over a 2.5 -year period (1998-2000), seeds from Ficus were predominant in the droppings of both species and met these criteria, particularly hemiepiphytic species (41% of droppings of A. jubatus) and Ficus variegata (34% of droppings of P. v. ianensis and 22% of droppings of A. jubatus). Information from bat hunter interviews expanded our knowledge of the dietary habits of both bat species, and corroborated the fecal analyses and personal observations. Results from this study suggest that A. jubatus is a forest obligate, foraging on fruits and leaves from plant species restricted to lowland, mature natural forests, particularly using a small subset of hemiepiphytic and other Ficus species throughout the year.

  • Emergence and Returning Activity in the Indian Flying Fox, Pteropus Giganteus (Chiroptera: Pteropodidae)
    International Journal of Geography and Geology 1(1):1-9 International Journal of Geography and Geology journal homepage: http://aessweb.com/journal-detail.php?id=5011 EMERGENCE AND RETURNING ACTIVITY IN THE INDIAN FLYING FOX, PTEROPUS GIGANTEUS (CHIROPTERA: PTEROPODIDAE) M. R. Sudhakaran1 D. P. Swamidoss2 P. Parvathiraj3 ABSTRACT Approach: After a diurnal resting in the roost, bats adapts some behavioural pattern to get themselves active towards foraging there by involving in various activities. Their activity pattern differs from time to time depending on the change in climatic factors. But the behavioural activities they involved varies from time to time. Observation was done on the emergence and returning gate i. e the emergence or returning of first to last bat, pre emergence behaviour and post return behaviour, and influence of moonlight on foraging activity. Key Words: Post return activity, emergence gate, behaviour, pre-emergence behaviour. INTRODUCTION Most of the megachiropteran’s found in the sub tropics roost in tents, in manmade structures like old houses and temples and in foliages or hollows in trees, mainly to evade from the climatic factors, which affect them. Indian flying fox, Pteropus giganteus roosts in open foliages of trees, a peculiar character of this genus. Papers dealing with behavioural aspects of P. giganteus are scarce. Apart from Neuweiler (1969), other works on behavioural aspects focused on copulatory behaviour (Koilraj et al., 2001), roost preference (Acharya, 1936), mating (Bhatt, 1942), local migration (Breadow, 1931; Nelson, 1965a) and general ecology and biology (Brosset, 1962). Bats roosting in closed environments involved in various behavioural activities during their emergence (Kunz, 1982) like light sampling, flying inside its roost etc.

  • Conventional Wisdom on Roosting Behaviour of Australian
    Conventional wisdom on roosting behaviour of Australian flying foxes - a critical review, and evaluation using new data Tamika Lunn1, Peggy Eby2, Remy Brooks1, Hamish McCallum1, Raina Plowright3, Maureen Kessler4, and Alison Peel1 1Griffith University 2University of New South Wales 3Montana State University 4Montana State University System April 12, 2021 Abstract 1. Fruit bats (Family: Pteropodidae) are animals of great ecological and economic importance, yet their populations are threatened by ongoing habitat loss and human persecution. A lack of ecological knowledge for the vast majority of Pteropodid bat species presents additional challenges for their conservation and management. 2. In Australia, populations of flying-fox species (Genus: Pteropus) are declining and management approaches are highly contentious. Australian flying-fox roosts are exposed to management regimes involving habitat modification, either through human-wildlife conflict management policies, or vegetation restoration programs. Details on the fine-scale roosting ecology of flying-foxes are not sufficiently known to provide evidence-based guidance for these regimes and the impact on flying-foxes of these habitat modifications is poorly understood. 3. We seek to identify and test commonly held understandings about the roosting ecology of Australian flying-foxes to inform practical recommendations and guide and refine management practices at flying-fox roosts. 4. We identify 31 statements relevant to understanding of flying-fox roosting structure, and synthesise these in the context of existing literature. We then contribute contemporary data on the fine-scale roosting structure of flying-fox species in south-eastern Queensland and north- eastern New South Wales, presenting a 13-month dataset from 2,522 spatially referenced roost trees across eight sites.

It is one of the largest fruit bat species found in the Indian subcontinent. They have one to two young. This bat is gregarious and roosts in colonies which can number up to 1,000 individuals, during the day. Due to various anthropogenic and environmental causes their populations are declining alarmingly. Current study has been aimed to know the population and its fluctuation in the “Kacharighat Roosting Site” of Dhubri town area of Assam. “Direct roost count” method was followed to estimate the population size of the colony. Observations were mostly done with the naked eyes . All total four roosting spots were identified in the roosting site. Highest population was recorded at 775 in the site. Total population of the roosting site was ranged between 720 and 775 during the study.
