Temperate-continental in the plateau, Alpine in the mountains.
Nesting in Switzerland
In Switzerland the House Sparrow usually nests April–August. Nest site: untidy nest under eaves, in ivy or a colony box. Clutches are 4–5 eggs, incubated for 11–14 days; chicks fledge after 14–16 days, and pairs raise 2–4 per year.
- Nest box: 32 mm hole; multi-chamber 'terrace' boxes suit colonies. 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.
