Close your office windows during weekends!
We rescued 100 bats of two species (Nyctalus noctula and Eptesicus serotinus) from one of the offices in Kharkiv city center.
People left the window frame open for one-week period and bats got stuck in such a trap.
It is bat migration period now, so they tried to find day roosts but got trapped inside the building and called other bats.
Almost all the bats were watered, ringed and released back to the wild, except for five weakened ones and six that were found already dead.
