what is it?

Cetti's warbler /ˈtʃɛti/, Cettia cetti , is an Old World warbler. It is a small, brown bush-warbler which breeds in southern and central Europe, north-west Africa and east southern temperate Asia as far as Afghanistan and north-west Pakistan. The bird is named after the 18th century Italian zoologist, Francesco Cetti. This species is very difficult to see because of its skulking habits.
