Figure 1

Generalized map of major Sylvia distributional areas (breeding) and important barriers discussed in text. Numbers in parentheses following area names indicate the number of species endemic to that area. Numbers on area-connecting arrows indicate that a given species is distributed in both of those areas; many species are distributed in multiple areas, and are therefore tallied on multiple area-connecting arrows. The dividing line for determining European versus Asian distribution is Turkey (dashed line). Circled numbers indicate island endemic species as follows: 1) Sylvia dohrni (Príncipe), 2) S. balearica (Balearic Islands), 3) S. sarda (Sardinia and Corsica), and 4) S. melanothorax (Cyprus).
