Tawny owl decline: Public urged to record ‘twit-twoos’


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.

"You can even do it from the comfort of your bed," said BTO's Claire Boothby.

Light pollution and urbanisation are thought to be impacting populations.

The conservation status of the Tawny owl recently changed from green to amber, signalling a growing concern for the species.

'Anyone can take part'

Researchers hope the Tawny Owl Calling survey, which runs from 30 September to 31 March, will help them understand if, and where, the bird may be in decline.

They say it is not essential that members of the public listen every single week, insisting that all data will be useful – even in locations where an owl call cannot be heard as this indicates where the species is missing.
