Typical warbler

[1][2][3][4] Typical warblers occur in the temperate to tropical regions of Europe, western and central Asia, and Africa, with the highest species diversity centred on the Mediterranean.

The plumage is in varying shades of grey and brown, usually darker above and paler below, with bluish or pinkish tones in several species; several also have orange-brown or rufous fringed wing feathers.

[6] Scopoli did not specify a type species but this was designated as the Eurasian blackcap (Sylvia atricapilla) by Charles Lucien Bonaparte in 1828.

[12] A molecular phylogenetic study using mitochondrial DNA sequence data published in 2011 found that the species in the genus Sylvia formed two distinct clades.

[13] Based on these results, the ornithologists Edward Dickinson and Leslie Christidis in the fourth edition of Howard and Moore Complete Checklist of the Birds of the World, chose to split the genus and moved most of the species into a resurrected genus Curruca retaining only the Eurasian blackcap and the garden warbler in Sylvia.
