Ynghylch

Named after 18th century zoologist, Francesco Cetti, the Cetti's warbler is a medium-sized warbler of willow scrub, marshes and nettlebeds. It can be very difficult to spot, but you may well hear it singing loudly from the cover of dense bushes. Resident all year-round, in summer, male Cetti's warblers spend their time defending territories, while the females lay their bright red eggs and raise their chicks.

What to look for

Cetti's warblers are rich chestnut-brown above and grey below, with a pale throat. They have a long, often cocked, tail. Best recognised by their explosive song.

Where to find

Resident in Southern England and South Wales.
