Cetti's Warbler, pronounced "Chetty's" and named after an Italian zoologist, is like an over-sized wren
with plain brown plumage and a pale front. It is a shy bird, not often seen; it's explosive song is usually the only evidence that it is around.
It has ten tail feathers, unique for British song birds which usually have twelve, and lays red eggs.

Cetti's is native to much of Europe through to northwestern China and has 3 subspecies: the nominal European
(includes NW Africa), Turkey to the Middle East, and the Central Asian shown.
The insectivorous bird usually frequents waterside habitat.
