“…As has been suggested from studies in North America and in continental Europe (Davis and Hitchcock, 1965;Hall and Brenner, 1968;Fenton, 1969;Schowalter, 1980;Bauerova and Zima, 1988;Degn et al, 1995;Kugelschafter, 1995;Lubczyk and Nagel, 1995) the dominant species participating in this activity are of the genus Myotis. Swarming in Britain appears particularly prevalent among M. nattereri and M. daubentonii, but this could in part reflect their relative abundance compared with the other Myotis species (Harris et al, 1995).…”

“…Swarming has been investigated in Microchiroptera from North America (Davis, 1964;Davis and Hitchcock, 1965;Hall and Brenner, 1968;Fenton, 1969;Humphrey and Cope, 1976;Thomas et al, 1979;Schowalter, 1980;Whitaker and Rissler, 1992) and continental Europe (Bauerova and Zima, 1988;Harrje, 1994;Degn et al, 1995;Kreutzschmar and Heinz, 1995;Kugelschafter, 1995;Lubczyk and Nagel, 1995;Trappmann, 1997). However, swarming has, until recently, gone unnoticed and unstudied in Britain.…”

“…Swarming aggregations frequently consist of more than one species, and there is usually a strong male bias (Davis and Hitchcock, 1965;Hall and Brenner, 1968;Humphrey and Cope, 1976;Thomas et al, 1979;Bauerova and Zima, 1988). Most bats arrive after dusk and stay for only a few hours before leaving again, meaning that there are typically few bats present during daytime (Hall and Brenner, 1968;Humphrey and Cope, 1976;Harrje, 1994). Several authors have divided the swarming season into two distinct phases: (1) the 'swarming' phase where bats rarely stay longer than a few hours on one night and (2) the 'arrival' or 'in-flight' phase where bats are beginning to enter hibernation, remain at the site during the day and are relatively inactive when compared with the previous phase (Fenton, 1969;Degn et al, 1995).…”

We investigated the extent of visitation of underground sites during late summer and autumn ('swarming') by bats. Bats were captured at eight cave, mine and tunnel sites in southern England over 6 years (1995)(1996)(1997)(1998)(1999)(2000). A total of 3077 bats representing 11 of Britain's 16 species was caught. Myotis bats predominated in autumn. At some sites these are rarely seen during winter hibernation counts. Myotis nattereri and M. daubentonii were most common. However, species composition changed seasonally. At one site, M. brandtii dominated early in the season and at all sites peak activity of M. daubentonii was earlier than in M. nattereri. Relatively high numbers of internationally vulnerable species such as M. bechsteinii and Barbastella barbastellus were recorded. There was a strong male bias in captures of swarming species. Swarming probably has an important reproductive function, most males are reproductively active at this time and such sites may be important for outbreeding. Due to this and the large number of individuals and species concerned, the conservation of 'swarming sites' is vitally important. Clearly swarming sites merit special consideration in conservation management strategies for cave-dwelling bats. #

“…The little brown myotis mates at swarming sites that also serve as hibernacula (Davis 1964;Davis and Hitchcock 1965;Fenton 1969;Hall and Brenner 1968;Kunz et al 1998;Schowalter 1980;Thomas et al 1979). At these sites, bats copulate indiscriminately and promiscuously beginning in August, and males sometimes mate with torpid females throughout the hibernation period (Thomas et al 1979).…”

Seasonal phenology of the little brown bat (Myotis lucifugus) at 60° N

To investigate the impact of short summers and long summer solar periods at high latitudes on the behavior of a nocturnal, hibernating mammal, we recorded the phenology of Myotis lucifugus (little brown myotis) at 60° N in the Northwest Territories (NWT), Canada. In particular, we assessed the timing of spring emergence from, and autumn entry into, hibernation, reproduction, and seasonal mass fluctuations. We used a combination of acoustic monitoring and capture surveys at two hibernacula and two maternity roosts during 2011 and 2012. Myotis spp. were active at the hibernacula from late April to late September/early October, suggesting that the “active” season length is similar to that of populations farther south. At maternity colonies, we detected M. lucifugus activity from early May to early October, with peaks during mid‐July in both years. Lactation, fledging, and weaning all occurred later in the NWT than at more southern locations, and reproductive rates were significantly lower than rates observed farther south. The average mass of individuals fluctuated throughout the season, with an initial decline immediately following emergence from hibernation likely reflecting increased energy expenditure due to flight and decreased use of torpor, coupled with relatively low prey intake due to low prey abundance associated with cool temperatures. Females did not appear to have lower pre‐hibernation masses than those in more southern populations, suggesting that despite the cool spring and autumn temperatures, and short summer nights, bats are able to obtain enough energy for reproduction and mass accumulation for hibernation. However, the lower reproductive rates may indicate that there are limitations to life at the northern limits of the species' range.
