Lasionycteris Noctivagans

We used radiotelemetry to examine the roost-site preferences of four species of tree-roosting bats (Eptesicus fuscus, Lasionycteris noctivagans, Myotis evotis, and M. volans) in southern British Columbia, Canada, by radio-tracking bats to their day roosts. We found a total of 21 roost trees: 14 roosts were beneath loose bark, 5 were in cavities excavated by woodpeckers, and 2 were in natural cavities. Entrance height increased with tree height, but roost entrances tended to be situated below the level of the canopy. Of the 22 tree and site variables examined, only 3 significantly discriminated between roost trees and available trees: tree height, distance to the nearest available tree, and percent canopy closure. Bats preferred tall trees associated with low percent canopy closure and a short distance to the nearest available tree. Bats roosted in western white pine, and to a lesser extent ponderosa pine and western larch, in intermediate stages of decay more often than would be expected at random. Bats switched roosts frequently. The distance between subsequent roost trees was short, suggesting a degree of fidelity to a particular group of trees or area of forest. The number of days of rain during the roosting period significantly influenced the number of days spent in a particular roost, and thus ambient conditions may restrict the frequency with which bats can switch roosts.

One hundred and sixty-nine bats belonging to 6 different species and collected from 4 ecological zones (aspen parkland, boreal forest, grassland, and montane) in Alberta, Canada, during 1988 and 1989 were examined for helminths. Forty bats were infected with the stomach nematode Longibucca lasiura McIntosh and Chitwood, 1934. Sample size, prevalence, and mean intensity (with range in parentheses) of L. lasiura for the 6 species of bat were as follows: Myotis lucifugus, N = 130, 27%, 39 (1–121); Myotis ciliolabrum, N = 10, 10%, 1; Eptesicus fuscus, N = 6, 33%, 12 (2–22); Lasionycteris noctivagans, N = 2, 100%, 22 (5–39). Myotis evotis (N = 9) and Lasiurus cinereus (N = 3) were not infected. Longibucca lasiura was found in bats from all ecological zones except the boreal forest. This parasite was found in bats active during summer (June to August) and in hibernating M. lucifugus collected in September and April.

Habitat use, temporal activity, foraging behaviour, and prey selection of hoary bats (Lasiurus cinereus) and silver-haired bats (Lasionycteris noctivagans) were studied at Delta Marsh, Manitoba. Bat activity was assessed by monitoring echolocation calls with ultrasonic detectors. Prey availability was determined using sticky and Malaise traps and dietary information was obtained from fecal analysis. Both species were active all night and foraged primarily in the lee of a narrow forested ridge. Lasionycteris noctivagans foraged in a manner that indicates that it detects and pursues prey over short distances. These bats fly slowly, are highly manoeuverable, and were commonly observed feeding on swarms of insects in small clearings. They use echolocation calls that support the notion of a short-range foraging strategy and feed opportunistically on whatever insects are available. Lasiurus cinereus, on the other hand, uses a long-range prey detection and pursuit foraging strategy. They fly rapidly along straight line paths in open areas and use echolocation calls designed to detect insects at a distance. The diet consists primarily of large insects (moths, beetles, and dragonflies), but the bats nonetheless feed opportunistically. The foraging strategy likely restricts the availability and profitability of small insects as prey.

Lasionycteris Noctivagans

Three lasiurine bat species, Lasionycteris noctivagans (Silver-hairedBat), Lasiurus cinereus (Hoary Bat), and Lasiurus borealis (Red Bat),have been recorded in inland, coastal, and offshore locations as of NovaScotia. Although these records occurred over a century, 70% are from themid-1990s or later, largely because of research in mainland Nova Scotia,and increased interest on Sable Island. The 65 records presented hereinclude 11, 25, and 29 for Silver-haired, Hoary, and Red bats, respectively,of which 31 are previously unpublished. Seventy-seven percent of recordsare from August through November, the autumn migration period forlasiurine bats. These observations suggest that most autumn occurrencesof these species in Nova Scotia are not extralimital, but are part of normalmigratory patterns in the province.
