The wood warbler (Phylloscopus sibilatrix) is a common and widespread leaf warbler which breeds throughout northern and temperate Europe, and just into the extreme west of Asia in the southern Ural Mountains. The genus name Phylloscopus is from Ancient Greek phullon, "leaf", and skopos, "seeker" (from skopeo, "to watch"). The specific sibilatrix is Latin for "whistler".
