Bird lovers are being urged to give up 20 minutes every week to listen out for the "twit-twoo" call of the Tawny owl, amid concerns over its numbers.
The British Trust for Ornithology (BTO) is asking people to listen for the distinctive hoot from their garden, a local park or woodland, once every week for the next six months.
