Winter
time is associated with decrease of available food for many animals.
Therefore, some of them go to sleep known as the hibernation.
Hibernation is a state of slow metabolic rate and slow heart beat, so
the energy is saved and an animal can survive winter. One of the
hibernating animals are bats. Yesterday my husband and I visited the
Upper Wierzchowska Cave that is located about
15
km northwest of Kraków. We
are very grateful and happy that we could admire a hibernating lesser
horseshoe bat (Rhinolophus hipposideros).
