Habitat and Nesting
The serin breeds across southern and central Europe as well as north Africa. In Europe, serins migrate south in the autumn, returning in the spring, and this is when they are most likely to be seen in Britain, typically along the south coast.
Breeding starts in May when the female builds its nest. This is usually in a tree or bush in open woodland, scrub, or gardens. However, only a few breed in Britain, usually along the south coast of England.
The nest is a neatly constructed of stems, roots, and moss that is lined with feathers and hair. When ready, the hen lays around 3 – 5 eggs and incubates them for 13 days. The eggs are about 17 mm long and are smooth, glossy and pale/light blue with purplish speckles in colour.
Once hatched, both parents feed the young.
