The master paper focuses on bats in Aukštaitija National Park territory. Object of the work - bats in Aukštaitija National Park territory. Method of the work - flying bats were detected with an ultrasound detector BATBOX Duet. The ultrasound was recorded with a dictaphone and later analysed with BatSound 1.20 software. The research locations were chosen according to the literary sources as well as while travelling in villages and neighbourhoods, observing the places where bats are most likely to feed and reside. Fifteen locations were chosen for the research. The results of the work. In Aukštaitija National Park seven kinds of bats were detected: Myotis dasycnem, Plecotus auritus, Myotis daubentonii, Nyctalus noctula, Pipistrellus nathusii, Pipistrellus pipistrellus, Eptesicus serotinus. The biggest number of the bats detected belongs to Pipistrellus nathusii and Myotis daubentonii. Myotis daubentonii and Myotis dasycneme were feeding while flying over water; other kinds of bats in Aukštaitija National Park were feeding while flying around leafy trees. Plecotus auritus, Nyctalus noctula , Pipistrellus nathusii, Pipistrellus pipistrellus and Eptesicus serotinus were feeding while flying near the trees in more spacious areas. Most often bats were feeding near black alders.
