When to expect serins in Portugal

The Serin lives in Portugal all year round. Mild, wet winters that attract many wintering European songbirds.

Mediterranean with strong Atlantic influence, wetter in the north.

Nesting in Portugal

In Portugal the Serin usually nests March–July. Nest site: cup in trees. Clutches are 3–4 eggs, incubated for 12–13 days; chicks fledge after 14–16 days, and pairs raise 2 per year.

  • The Serin 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.
