When to expect blackcaps in Wales
The Blackcap arrives in Wales in spring to breed and leaves again in autumn. Cool, damp summers with long daylight; oak woodland supports Pied Flycatchers and Redstarts.
Mild, wet maritime climate with upland moorland and sheltered coastal valleys.
Nesting in Wales
In Wales the Blackcap usually nests May–July. Nest site: cup in brambles. Clutches are 4–5 eggs, incubated for 11–13 days; chicks fledge after 11–12 days, and pairs raise 1–2 per year.
- The Blackcap 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.
