Natural history of the fishing bat Noctilio leporinus (Chiroptera: Noctilionidae) in the Gulf of Mexico

We report feeding behaviour, dates of peak reproduction, and sexual size dimorphism of the fishing bat, Noctilio leporinus, in the Gulf of Mexico. For the first time we document the size of cheek pouches in N. leporinus and fish species consumed in the water bodies of southern Mexico and analyse differences in wing morphology and biomechanical flight descriptors between the sexes. We found sexual dimorphism in size for most of the external measurements but not in wing characters. This species can consume prey up to a third of its size. We confirmed the presence of N. leporinus in localities in Tabasco, Mexico 60 years after the first report.
