Bestimmung

Cetti's warbler is approximately 13–14 cm (5.1–5.5 in) from bill to tail. The male weighs 15 g (0.53 oz) and the female 12 g (0.42 oz). Cetti's warbler has a rounded head with a narrow pale grey stripe arching over conspicuous black eyes, and short, rounded wings. The upperparts are a rich chestnut or dark reddish-brown; the throat and breast are pale grey. The tail is longer and broader than many other warblers.The sexes have similar plumage, but males are 26% to 32% heavier than females with a wing-length 11.2% to 13% longer. The male has a wing longer than 60 mm; the female has a wing shorter than 55 mm. The birds can be aged by their plumage; juveniles look similar to adults but have fresh plumage and two dark or dark grey spots on the tongue. Cetti's warbler is unusual among passerine birds in having ten tail feathers (rectrices) rather than the usual twelve.<p>Cetti's warblers signal their presence with loud song. Their song is distinct, comes in loud bursts, and has a unique structure that allows the birds to avoid mating with other species.

Taxonomie

Cetti's warbler was described in 1820 by the Dutch zoologist Coenraad Jacob Temminck from specimens collected by Alberto della Marmora in Sardinia. Temminck coined the binomial name Sylvia cetti. 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.<p>Three subspecies are recognised:

Verbreitung und Lebensraum

Cetti's warbler usually inhabits damp areas including ponds, lakes, marshes and rivers. It is insectivorous.<p>The number of Cetti's warblers has greatly increased across Europe since 1990. The current population of Cetti's warblers in Europe is estimated to be about 600,000-1,600,000 breeding pairs. The populations in Italy and Turkey are known to be stable or increasing. The exception to the general positive European population trend is Greece, where the population decreased slightly between 1990 and 2000. However, overall, Cetti's warblers are evaluated as secure. Cetti's warbler was first recorded in the United Kingdom in 1961. The UK population of Cetti's warblers fell by over a third between 1984 and 1986 following a severe winter, but rebounded rapidly thereafter. Populations continue to grow; by 2016 there were over 3,400 territorial males, distributed throughout most of England and Wales, with the first breeding in Scotland in 2023. It was first recorded in Ireland in 2013, with the first breeding in 2022.
