Nesting in Switzerland
In Switzerland the Treecreeper usually nests April–June. Nest site: behind loose bark or ivy. Clutches are 5–6 eggs, incubated for 14–15 days; chicks fledge after 15–16 days, and pairs raise 1–2 per year.
- The Treecreeper does not use enclosed nest boxes — dense native shrubs and climbers give it nest sites.
- 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.
