Monitoring hand-reared bats post-release takes organisation and knowledge of appropriate methods and often is beyond the skills and capacity of individual bat carers.
However further advice and support may be found if a suitable opportunity (for example a large number of babies from a known roost) occurs.
If this is likely, organisation must start as soon as the bats come into care.
The limited knowledge we have of survival after release has come from initiatives taken by bat carers.
