Moments worth waiting for
- Wing-clapping display
A short-eared owl climbs into the air, claps its wings and dives in an ancient courtship flight.
Photo tip
Sit still at the edge of a field or bracken at the end of the afternoon and let the owl quarter past. Use 400–600 mm, 1/2000 s and continuous focus. A low, dusk-glow sun gives lovely light on the wings.
Be a good naturalist
Short-eared owls nest on the ground, so keep to the path; a nest hidden in bracken is easy to step on. Never flush a bird to get it in the air, and follow the wardens' advice.
The law
Not on Schedule 1 (no licence is needed to disturb it), but all wild birds and their nests are protected under the Wildlife and Countryside Act 1981. Ground-nesting owls are easily disturbed; it is on Annex 1 of the EU Birds Directive and a Rare Breeding Birds Panel species since 2010
