LISTEN: Mysterious sound of long-eared owls recorded in Mayo

The mysterious sound made by long-eared owls has been recorded in Mayo by local photographer Alison Laredo.

She said: "If you hear a persistent whistling sound on a summer’s night, it could be long-eared owl chicks calling to their parents for food."

She thanked Alan Mee of Castlebar Tidy Towns for helping to identify the unique call.
