When to expect tree sparrows in Norway

The Tree Sparrow lives in Norway all year round. Coastal winters are milder than latitude suggests; inland winters are severe.

Mild maritime on the Gulf Stream coast, cold continental inland and Arctic in the north.

Nesting in Norway

In Norway the Tree Sparrow usually nests May–July. Nest site: tree hole or box. Clutches are 5–6 eggs, incubated for 12–13 days; chicks fledge after 15–18 days, and pairs raise 2–3 per year.

  • Nest box: 28 mm hole. Put boxes up by February and clean them out between September and January.
  • Avoid cutting hedges during the nesting season (roughly March to August) — in the UK, disturbing an active nest is an offence under the Wildlife and Countryside Act 1981.
