When to expect jays in Sweden
The Jay lives in Sweden all year round. Long, cold winters with snow; feeders keep tits, Nuthatches and finches going for months.
Temperate in the south, boreal across most of the country and subarctic in the far north.
Nesting in Sweden
In Sweden the Jay usually nests May–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.
