Tawny Owl
Classic ‘tu-whit tu-whoo’ of British nights — round face, dark eyes, woodland ghost.
Least Concern
Strix aluco
Overview
Tawny owls are the UK’s most familiar woodland owls, hunting small mammals from tree perches after dark. Their hooting duets define British night soundscapes, and rounded heads with dark eyes set them apart from yellow-eyed barn owls.
For UK collectors, the tawny is a common night icon — garden woodlands, unmistakable calls, and a staple of British fieldcraft after dusk.
