Calling Tawny Owl Survey

This winter, whether you hear tawny owls calling or not then please take part in the BTO survey. This will help understand their calling behaviour and distribution, and discover the impact of urbanisation and artificial lighting.

BTO needs your help, whether you usually hear Tawny Owls or not. Knowing where owls can't be heard is just as valuable as knowing where they can be heard.

Please post your results up until 31 March 2019
