Nesting in Switzerland
In Switzerland the Jay usually nests April–June. Nest site: twig cup in trees. Clutches are 4–5 eggs, incubated for 16–17 days; chicks fledge after 21–23 days, and pairs raise 1 per year.
- The Jay 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.
