When to expect jays in Spain
The Jay lives in Spain all year round. Mild, wetter winters host many northern European migrants — Robins, Chiffchaffs and Blackcaps.
Mediterranean across most of the country, oceanic in the north (Galicia to the Basque Country) and semi-arid in the south-east.
Nesting in Spain
In Spain the Jay usually nests March–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.
