A "bat walk" in a park has been scheduled for next month.

The event, led by Wren Group's Tim Harris who will provide bat detectors, is meeting at the Tea Hut in Wanstead Park on September 4 at 7.30pm until around 10pm.

The bat detectors work by picking up on the high frequency calls they emit.

Species of bat known to inhabit the park include the common noctule, the Daubenton's bat and the Soprano Pipistrelle.
