Marmora's warbler (''Sylvia sarda'') is a typical warbler, genus ''Sylvia''. It breeds on Mediterranean islands, typically including Corsica and Sardinia. The smaller Balearic Islands bird is increasingly given specific status as Balearic warbler, ''Sylvia balearica''. These two seem to form a superspecies which in turn groups with Tristram's warbler and the Dartford warbler (Helbig 2001, Jønsson & Fjeldså 2006). They are generally resident but some birds migrate south to winter in north Africa. They are rare vagrants to northern and western Europe. These are small, long tailed, large-headed birds, overall very similar to their close relatives in the Dartford warbler group. Marmora's warblers are grey above and below, lacking the brick-red underparts of the Dartford warbler. Adult males have darker patches on the forehead and between the eye and the pointed bill. The legs and iris are red. The song is a fast rattle. Immature birds can be confused with young Dartford warblers, which are also grey below, but Marmora's have a paler throat. Their iris is dark. These small passerine birds are found in open country with thorny bushes and heather. 3-5 eggs are laid in a nest in a bush. Like most warblers, they are insectivorous. This bird is named after the Italian naturalist Alberto della Marmora. ==References== *Helbig, A. J. (2001): Phylogeny and biogeography of the genus ''Sylvia''.
