Nuthatch

Sitta europaea

Diet

Insects and spiders in summer; hazelnuts, beech mast and acorns in autumn and winter, wedged in bark and hammered open.

Habitat

Mature broadleaved woodland, especially oak and beech, and parkland with old trees.

Breeding

Nests in a hole in a tree (or nestbox) from April, the entrance narrowed with mud; typically 6–8 eggs, usually one brood.

Field signs

  • Loud, ringing 'twit-twit-twit' or 'chwit' calls
  • Mud-plastered rim to a nest hole
  • Nuts wedged in bark crevices
  • A bird descending a trunk head-first

Did you know?

  • Most tree-climbing birds, such as woodpeckers and treecreepers, climb upwards; the nuthatch also walks head-first down trunks.
  • The nuthatch plasters mud around its nest entrance to shrink it to exactly its own width, keeping larger birds out.
  • It has spread north across Britain since the 1970s (BTO) but is still scarce in northern Scotland.

Moments worth waiting for

  • Head-first descent all year, dawn and day
    A nuthatch spirals down the beech trunk, head first, tapping a nut into a crack.
  • Plastering the nest hole March to April, day
    A pair carries beakfuls of mud to a tree hole, shrinking the entrance to fit.

Photo tip

Sit near an oak or beech with a good spread of old trunks, or use a garden feeder in winter. A 400 mm lens from a low position works; use burst mode as it never stays still.

Be a good naturalist

A nest hole is protected while in use. Keep at least 20–30 m from the nest tree and never scrape or enlarge the entrance. Do not use playback of calls.

The law

Protected under the Wildlife and Countryside Act 1981.
