On one occasion we saw three individuals roosting together about 10 m above the ground beneath a disused bird's nest. The movement between roosts was not uniform each month, but f ollowed a pattern involving two d istinct phases, each lasting several months. As calls were only audible f rom a range o f about 50-75 m, roosts further away were not found. In so doing, descriptions of resource location, individual home range and resource use (flower host, roosting place, etc.) were provided. Ranking roosting structures by durability and protection, we sought correlations among bat species in prevalence, mean intensity and number of associated fly species. Throughout the diurnal home range, the colony roosted in 20 families of trees (27 genera and 31 species). The male used six roosts in 9 days, the female two roosts in 5 days. On four subsequent checks of the site, we did not find any more bats roosting there. The animals also tended to use certain species of trees as roosts. Similarly, it is also uncertain why larger trees were chosen as roosts. The bats preferentially roosted in certain species of trees. The numbers of days in which the animals roosted within the grid are shown. However, availability of roosting sites does not seem to play a crucial role in the present case. Apart from identifying suitable roosting sites, it is also important to know the kinds of food resources that sustain these populations in urban areas. All of the leaf pellets were collected under the daytime roosts and feeding roosts. Furthermore, our tracking data suggested that the bats probably roosted somewhere rather high up (c. 20 m) in the canopy. However, roosting habits were not correlated with the average wing development of bat flies. Outside of roosts, contact between bats that is sufficient for ectoparasites to achieve transfer is extremely unlikely. On another occasion two individuals (one female and the other not captured) were observed roosting near the collapse point along the midrib. In one instance we found a single adult male roosting in a tent. Two other species, located in their day roosts, also have been recorded from the area. Data on the day roosts of 23 other species were determined from the literature. The noise from such roosts, and the accumulated droppings, are a nuisance to residents who live nearby. A plethora of local and global factors besides roosting habits influence relationships between bat flies and their hosts. The roosting habits of bat species vary greatly in relation to bat fly development. The diurnal home range, which encompassed all the various roosting sites, was 1120 ha. In this exozoochorous type of dispersal, the diaspores are usually dropped under the roosts or by accident during flight. We also triangulated the positions of the day roosts of two tagged bats. Tents and harems: apparent defence of foliage roosts by tent-making bats. Over a period of about 50 d, a single adult male constructs an entry/exit portal and a partially enclosed, dome-shaped roosting space surrounded by uncut stems and leaves. We located three other roosts. Nursery roosts and community diversity of nearctic bats. If a species was known from three roosts ranked 6, 6 and 5, the weighted rank was calculated as (3 x 6 + 2 x 6 + 1 x 5)/6 =5.83. However, alternate roosts used by males were apparently distributed over a larger area since they were absent from the study area when they were not resident in their primary tent. Indeed, only two individuals, one male and one female, were recorded more than 500 m from their day roosts throughout the radio-tracking period of this study. Second, if some individuals in the population never use rolled leaves as roosts, then they would have entirely escaped detection, and we would have underestimated population size. Of the 206 roosts (out of 255 total) in which all o f t he bats were captured, 12 roosts contained a single female and 8 contained a single male. During the subsequent 16-d census period, 15 marked males and 17 marked females were observed roosting in the study area on one or more censuses. Tents and harems: apparent defense of foliage roosts by tent-making bats. The evidence suggests that differences in foraging behaviour and diet may better explain the diversity of bats than the variety of day roosts used in any area. Our method mostly did not allow precise localization of bats in flight, but it permitted a reasonable estimate of the size of the foraging and roosting areas. Intermittent transfers by females between groups suggest that the defence of diurnal roosts by males represents a more profitable mating strategy than the direct defence of compositionally labile female groups. Selection of day roosts by red bats in mixed mesophytic forests. First, all of the rolled leaves examined may not have been suitable for roosting bats, because of their size, microclimate or exposure to rain or sunlight. Correlations between roosting structures and parasite loads raise the interesting possibility that the diversification of bat roosting structures may be partly a response to escape ectoparasites. A peculiar roosting habit of bats. I test the hypothesis that bats will select higher, larger leaves that will provide maximum safety from predators as well as stability for sustaining the weight of the bats roosting. The tree was 16 cm in diameter (breast height), and through the opening in the base we could see the roosting bat 1- 1.5 m above the ground, apparently alone. The reason for this high density was unknown but an abundance of food, suitable roosts, or concentrations due to mating behaviour may have contributed to its local abundance. While future studies must control a much wider range of variables, finding significant relationships between parasitism and roosting across such a broad diversity of both bats and parasites is remarkable. The conservation bodies have lists of products which are acceptable for use in roosts; products containing lindane are not recommended for this purpose.

Rather, amount of exposure to ectoparasites more likely is related to number of roosts or sizes of social groups with which individuals are associated. However, it was quite common for some fruits to be dropped undamaged under the feeding roosts or day-time roosts. Reduced-wing or wingless flies are associated with various unrelated clades of bats, seemingly without regard to roosting habits. Correlations between roosting habits and levels of parasitism are low when all bats are considered. However, palms are also roosting sites for frugivorous bats which may disperse small seeds to palm sites. Individual females were also found roosting sequentially with up to three different males. Radio-tagged individuals invariably roosted within or beneath tangles of vines and leaves. However, roosting habits alone do not explain the absence or paucity of streblid flies from these families. Because they feed on high-quality fruits, understorey frugivores feed in a series of discontinuous bouts separated by long periods of roosting or sleeping. Unfortunately, it was not possible to observe the bats at the day roosts, because the vegetation at the most probable locations was very dense. Overwintering sites were also censused during late morning to exclude the unlikely possibility that inhabitants were simply roosting (and otherwise reproductively active). An alternative explanation is that a given sample of diurnal roosting groups will include only those males that have successfully defended territories and recruited females. Individuals roosted in tight clusters, and were often in physical contact. The solid bars indicate the upper and lower 95% confidence limits of the diameter of known roosts.
