Did you know?
- Dunnocks live a complicated love life: both sexes may mate with several partners (BTO).
- A 'hungry gap' in February and March, when natural food runs short, can hit their survival (BTO).
- Sometimes called the 'hedge sparrow', it is not related to sparrows at all; it has a thin insect-eater's bill.
Moments worth waiting for
- Singing from the top
A dunnock leaves the hedge base and sings from the very top of a bare shrub, wings flicking.
Photo tip
Sit still by a hedge with spilt seed at its base and let it come to you. Shoot from ground level at first light, and use the song perch in spring when it is more open.
Be a good naturalist
Leave hedges untouched during nesting (Mar–Aug). Give ground food only in small amounts so it is eaten the same day.
The law
Protected under the Wildlife and Countryside Act 1981; it is an offence to damage an active nest.
