“…This is similar to the data from Ireland with 51 % (Sullivan et al 1993) and 50 % (Flavin et al 2001). It also underlines, that our overall findings are not only reflecting a local situation but are comparable to other populations of M. daubentonii across its distribution area.…”

“…Its distribution is strongly associated with lakes, ponds, rivers and streams. The current knowledge of its feeding ecology and behaviour suggest that M. daubentonii forages along waterways and adjacent habitats (Jones & Rayner 1988, Bogdanowicz 1994, Arnold et al 2000, Warren et al 2000, Flavin et al 2001, Ciechanowski 2002, Dietz et al 2007). Among the "trawling Myotis", which includes all Myotis species hunting directly over water and sharing similar morphological adaptations, e.g.…”

“…During the breeding season, it is a tree-dwelling species occupying hollow branches, woodpecker holes, crevices, or finding sometimes shelter behind loose bark (Ebenau 1995;Rieger 1996a, b;Kapfer et al 2006). It hunts over water surfaces, feeding mainly on Chironomidae (Diptera, Nematocera) and Trichoptera, caught either by aerial hawking or by gaffing from the water (Jones and Rayner 1988;Sullivan et al 1993;Flavin et al 2001). Ponds are often very productive habitats, but are limited in number.…”

We investigated roosting and hunting site fidelity of Daubenton's bats Myotis daubentonii (Kuhl, 1817) Roosting behaviour and hunting activity over ponds of adult females and juveniles were monitored using radiotelemetry. Eighteen roosts were located, all in natural cavities. The bats occupied a limited number of trees located in a specific and small roosting area. This roost aggregation was not linked to the distribution of hollow trees. Furthermore, whereas all 11 ponds in the study area were exploited by Daubenton's bats, monitored individuals were limited to two ponds to which they showed high fidelity. These two ponds were not the closest to the roosting area. Overall, these results show that at least for the time we conducted our experiment, female and juvenile Daubenton's bats are highly faithful to specific roosting and hunting grounds.

“…It was shown that for temperate bats of aerial hawkers, the food availability in October decreases to one quarter or even one tenth in comparison to its greatest abundance in July and August (Speakman and Rowland 1999). In fact, bats with the early swarming peak of activity forage mainly on flying prey (Flavin et al 2001;Pithartová 2007;Lučan et al 2009;Krüger et al 2012;Andreas et al 2012b;Nissen et al 2013). …”

Activity pattern and fat accumulation strategy of the Natterer’s bat (Vespertilionidae, Chiroptera) swarming population indicate the exact time of male mating effort

Studies concerning bat autumn swarming behavior suggest that the main purpose of this phenomenon is mating. However, the process of fat accumulation is crucial for surviving winter, and it seems to be in clear conflict with a need to strive for the opportunity to mate prior to hibernation. Investment in one activity limits the other one creating a trade-off between them. The aim of our study was to describe the activity pattern of each sex-age group (adult males, adult females, subadults) of the Natterer's bat during swarming period and to investigate the fat accumulation process of adult males in the context of their reproductive strategy. Bats were captured by mist nets at the swarming site fortnightly from the early August until the late November. The age, sex, reproductive status, and body condition index (mass to forearm ratio, BCI) were recorded. The activity peak of both sexes, adults, and subadults was observed in the late September. That time in season, BCI of adult males was the lowest, and there was no correlation between the hour of an adult male capture and its BCI value within one night (r s = 0.23; p = 0.157). Such correlation was observed later in the season (early October: r s = 0.44; p = 0.020; late October: r s = 0.48; p = 0.002). A negative correlation between adult males' BCI and proportion of adult females was found (r = 0.44; p = 0.000). We conclude that the activity peak of females is likely to be responsible for the effort of the mating behavior of the males, which is reflected by their low condition index. We suggest that the gleaning foraging strategy of Natterer's bat allows the males to postpone their fat accumulation until just before hibernation.
