Brown long eared bats and Barns

Cherryfield Ecology has been undertaking surveys on a barn in Oxfordshire, last night we did the second of three surveys and decided to mist net the bats to see if they were male or female.

Brown long eared bats are known to have small maternity roosts and as we had at least two bats out of the barn on the previous survey we wanted to know if the bats were male or female.

We know they were coming from the main barn door so set - up the net across this so when they emerged they would have no were to go other than the net.

Some time later the brown long eared pictured below was caught. This little chap was male and pretty annoyed at being caught in the net.

After we had checked him over he was released to go and hunt for the evening.
