“…Migration has been reported by many investigators (Howell, 1920, Guthrie, 1933Folk, 1940;Cockrum, 1956;Villa R. and Cockrum, 1962; and others). Many migration records are local or diurnal in nature rather than seasonal and involve many species of Old and New World bats.…”

ABSTRACT:The thermal regulatory responses of bats to ambient temperature have been reviewed. The various types of bats (hibernators, migrators, tropical) have some degree of thermal regulation, although the complexity of its nature and mechanism is still unknown.

“…While the existence of a homin~ ability in bats has hecn demonstrated in many experiments reviewed by Cockrum (1956) and Griffin (1958), it is only recently that Cockrum (1956) and Mueller and Emlen (1957) have shown that some bats return rapidly enough to demonstrate an almost direct flight home. Yet most homing experiments have failed to show a high percentage of returns at speeds rn T cient to establish the fact of accurate homeward orientat ion rather than wandering or exploration until familiar territory is reached.…”

“…Some information exists on broad‐scale patterns of movement (i.e., continental) of a few species (Findley and Jones 1964, Cryan 2003, Cryan et al 2004), but little is known about finer scale behaviors and patterns (Barclay 1984, Fleming and Eby 2003). Due in part to the discovery of large numbers of migratory‐bat fatalities at wind energy facilities in the autumn (Ahlen 2003, Dürr and Bach 2004, Arnett et al 2008), the study of bat migration has had a resurgence of interest not seen since homing experiments conducted in the 1950s and 1960s (e.g., Cockrum 1956, Davis 1966, Griffin 1970).…”

Studying migratory behavior of bats is challenging. Thus, most information regarding their migratory behavior is anecdotal. Recently, however, fatalities of migratory bats at some wind energy facilities across North America have provided the opportunity and impetus to study bat migration at fine spatial and temporal scales. Using acoustic monitoring and carcass searches, we examined temporal and spatial variation in activity levels and fatality rates of bats at a wind energy facility in southern Alberta, Canada. Our goals were to better understand the influence of weather variables and turbine location on the activity and fatality of hoary bats (Lasiurus cinereus) and silver‐haired bats (Lasionycteris noctivagans), and to use that understanding to predict variation in fatality rates at wind energy facilities and recommend measures to reduce fatalities. Overall activity of migratory bats and of silver‐haired bats increased in low wind speeds and warm ambient temperatures, and was reduced when the wind was from the North or Northeast, whereas hoary bat activity increased with falling barometric pressure. Fatalities of migratory bats in general increased with increased activity of migratory bats, increased moon illumination, and falling barometric pressure and were influenced by the interaction between barometric pressure change and activity. Fatalities of silver‐haired bats increased with increased activity, moon illumination, and winds from the south‐east. Hoary bat fatalities increased with falling barometric pressure. Our results indicate that both the activity and fatality of migratory bats are affected by weather variables, but that species differ in their responses to environmental conditions. Spatially, fatalities were not influenced by the position of turbines within a turbine row, but were influenced by the location of turbines within the facility. Our findings have implications for our understanding of bat migration and efforts to reduce fatalities at wind energy facilities. To maximize the reduction of bat fatalities, operators of wind energy facilities could incorporate migratory bats' response to environmental variables, such as barometric pressure and fraction of moon illuminated, into their existing mitigation strategies. © 2011 The Wildlife Society.
