The emergence of cave-dwelling bats can be influenced by multiple variables, such as diurnal predator evasion, energetic requirements, and prey abundance. This work aimed to determine emergence patterns of cave-dwelling bat species from roosts over the April–July 2013 period in the Valencian Community (East Spain) by infrared camera and acoustic recordings. We observed that Miniopterus schreibersii left earliest followed by the Myotis myotis/blythii group and Myotis capaccinii and finally Myotis escalerai. This pattern of emergence was observed in four roosts with no significant differences. Miniopterus schreibersii tended to display quicker flight in open areas, compared to the Myotis genus. Moreover, the M. myotis/blythii group and M. capaccinii were larger in size and had a greater wing loading than M. escalerai. Therefore, variations in emergence times may be due to differences in predation pressure by diurnal and crepuscular predators, which would enable large and fast bats like M. schreibersii to le...
