What are bats up to in May?

May is a busy month for bats, particularly females who are finding suitable nursery roosts and establishing their maternity colonies.  For pregnant bats gestation will last for 40-50 days in smaller species and up to 70 days in larger bats.  In exceptionally favourable years’ females begin giving birth before the end of the month, but most babies arrive from mid-June onwards.   Males will be largely separate in their own roosts (individually or in small groups) and are not involved in the raising of young.

Bats will be active most nights, but will still occasionally return to periods of extended torpor during cold spells.   Spring is a critical time for bats who are vulnerable to disturbance.   If you find a grounded bat, please go to the bat rescue tab above.
