Discover interesting Cetti's warbler facts.

This article will tell you everything you need to know about a special species of warbler bird including details about its family members, physical description, distribution, range, migration, habitat, diet, song, behavior, breeding, current population, and conservation status.

Cetti's warbler (Cettia cetti) is a small brown bush warbler bird belonging to the Cettiidae family and is the genus of Cettia. The species was first introduced and described in 1820 by Coenraad Jacob Temminck, a Danish zoologist. The species is name was chosen in honor of the Italian zoologist Francesco Cetti. In general, their range occupies southern and central Europe, northwest Africa, and the east Palearctic as far as Afghanistan and northwest Pakistan. The genus was later classified as type species in 1834 by the French ornithologist Charles Lucien Bonapart, and further divided into three subspecies: Cettia cetti cetti – resident to west Europe to Greece, the Balkans, and northwest Africa, Cettia cetti orientalis – resident Turkey to Iran and Afghanistan, and Cettia cetti albiventris– resident to Kazakhstan and Turkmenistan to northwest China and northern Afghanistan. These birds are fairly common but more often heard than seen due to their sulking habits. They inhabit dense bushes, shrubs, reedy marshes, and hedges near shallow waters. There isn't much to add to their physical description as the plumage is plain with no significant markings, however, they differ from any other species as they are rather chunky, plumped, and have warm brown upperparts, pale grayish underparts, and thin gray-white eyebrows, and a long tail.

Males use their songs to attract females, a good song can attract several females into their respective territories. After the mating pairs or groups are formed, their nests are built in a spot that is well-hidden to keep predators away e.g. inside thick-dense vegetation, bushes, or atop tall trees usually, at around 12-18 in (30-45 cm) above the ground, they are built entirely by females, as males have several partners and continue attracting more females while doing this, they spend little to zero amount of time caring for the eggs or young chicks. The nests are cup-shaped, built haphazardly with twigs, moss, leaves, lined with finer materials, and look untidy. Cetti's warblers that occupy the European range lay eggs from mid-June. Eggs are unusually laid in the morning, a single clutch consists of about four to five chestnut brown-red eggs. The eggs are incubated in females for several weeks. The eggs hatch in 15-18 days.
