Feeding behaviour and foraging strategy of free-living mouse-eared bats, Myotis myotis and Myotis blythii
Article Abstract:
The foraging and feeding behavior of two kinds of insectivorous, mouse-eared bats, Myotis myotis and Myotis blythii, were examined. Results indicate that the alternative categories of prey captured by mouse-eared bats occur in vast numbers at certain times of the year. They switched to habitats offering more abundant or higher-body-mass prey. Mouse-eared bats can be viewed as opportunistic, generalist predators that know how to maximize average energy intake rate through balanced-habitat selection.

Ontogeny of vocal signals in the little brown bat, Myotis lucifugus
Article Abstract:
Developmental changes in the vocal signals emitted by free-ranging pre-volant and volant bats (Myotis lucifugus) were examined. Vocalizations from bats aged one to 33 days were recorded under conditions simulating flight-related behaviors in young bats. Ontogenetic evidence indicated that the maturation of the bats was accompanied by an increase in sound frequency, an increase in sound repetition and a decrease in sound duration.

Behavioral flexibility: the little brown bat, Myotis lucifugas, and the northern long-eared bat, M. sepatentrionalis, both glean and hawk prey
Article Abstract:
The behavioral changes of the little brown bat, Myotis lucifugas, and the northern long-eared bat, M. septentrionalis that glean prey from surfaces and take prey on the wing is demonstrated. Each species of bat is analyzed for their flight behavior and echolocation calls.
