In accordance with this hypothesis, mating takes place in autumn in temperate zone bats, when males are in good physical condition. This timing furnishes to females a better selection choice and allows the delivery of offspring in late spring or summer when the availability of food resources is maximal. During a study of cave-bat populations in Andalusia, southern Spain, some cases of winter reproduction in a colony of mouse-eared bats (Myotis myotis) were observed and herein reported
