When to expect blackcaps in Denmark

The Blackcap arrives in Denmark in spring to breed and leaves again in autumn. Cool summers with long evenings.

Temperate maritime, windy and low-lying, surrounded by sea.

Nesting in Denmark

In Denmark 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.
