The Spectacled Warbler shows a strictly Mediterranean distribution which is expected to expand northward in response to climate warming. To test this hypothesis, we defined the regular distribution of the species based on the literature and we tested whether: (1) spring temperatures in this area significantly increased between 1967 and 2010; (2) breeding attempts north of the regular range occurred progressively at northern latitudes.
Both of these hypotheses were confirmed, supporting the hypothesis that the species is expanding northward because of climate warming.
