  1. List of all groups of species that failed recognition via MOTU analysis. Additionally, species with aberrant NJ profiles are indicated; profile designations (a-d) refer to Figure 3. Bootstrap support is given for each species ("nm" denotes that the species is not monophyletic) and the average interspecific distance is given for each group of species, both as percentages. Whether groups could be distinguished via CAOS is also indicated.
  2. † Represents the ten members of the Herring gull complex listed in the text.
  3. ‡ Only two of four specimens of the paraphyletic Lanius collurio exhibited limited divergence from L. isabellinus.
