Cetti’s warbler has a fine bill, domed head, short round wings and a long tail.
They are dark brown with whitish-grey underparts. Their eyes are dark brown and their legs are pink.
Males and females look similar although the male is heavier. Juvenile birds are duller.
Cetti’s warblers breed from mid June. They build an untidy cup-shaped nest from leaves and stems lined with feathers, hair and flowers.
4-5 brick-red eggs are laid which are incubated by the female for 16-17 days. Chicks are fed on insects by the female and they fledge after 14-15 days.
Cetti’s warblers eat mostly insects and aquatic invertebrates. They will also eat snails, worms and occasionally seeds.
Where to see them
Cetti’s warblers live in damp areas close to wetlands. They can be seen all year round particularly in southern England and South Wales.
