Species of bird

Cetti's warbler '/tʃ//ɛ//t//i/ (Cettia cetti) is a small, brown bush warbler which breeds in southern and central Europe, northwest Africa and the east Palearctic as far as Afghanistan and northwest Pakistan. The sexes are alike. The bird is named after the 18th century Italian zoologist, Francesco Cetti. This species is very difficult to see because of its skulking habits. The specific epithet was chosen to commemorate the Italian zoologist Francesco Cetti. Cetti's warbler is now placed in the genus Cettia that was erected in 1834 by the French ornithologist Charles Lucien Bonaparte with Cetti's warbler as the type species. Three subspecies are recognised: Cetti's warbler is unusual among passerine birds in having ten tail feathers (rectrices) rather than the usual twelve. Cetti's warblers signal their presence with loud song.

Cetti's warbler usually inhabits damp areas including ponds, lakes, marshes and rivers. It is insectivorous. The number of Cetti's warblers has greatly increased across Europe since 1990. It was first recorded in Ireland in 2013, with the first breeding in 2022.

During the summer, the males spend most of their time establishing their territories. While doing this, they spend little amount of time caring for the eggs or young. Afterwards, the males usually attract more than one female to their territory. Their song plays an important role. In Europe the main period for egg laying is from the middle to the end of June. The nest is placed in thick dense vegetation usually at around above the ground. The untidy cup shaped nest is made from leaves and stems and is lined with feathers, hair and other finer material. It is built entirely by the female. The eggs are laid in the early morning at daily intervals and are chestnut red in colour. The clutch consists of 4 to 5 eggs which measure approximately The eggs are incubated by the female beginning when the clutch is complete and hatch after 16 to 17 days. The young are mainly fed and brooded by the female. They fledge after 14 to 16 days but continue to be fed by the parents for at least another 15 days. The young become independent by 30 days. In Europe Cetti's warblers normally have two broods each year. They first breed when one year of age.

Cetti's warbler preys on arthropods such as small, soft bodied insects and larvae. Cetti's warblers prefer tiny insects because they can digest them faster.
