Starch gel electrophoresis was used to compare 14 proteins
encoded by 15 loci for seven species of the family Icteridae.
A close genetic relationship among these species was classified
into three groups. The Agelaiine group contained Agelaius
phoeniceus, Sturnella magna, and S. neglecta. The Quiscaline
group contained Euphagus cyanocephalus, Cassidix mexicanus,
and Quiscalus quiscula. Molothrus ater, the most divergent,
was placed in a separate group. Divergence times for the
seven species were compared to the literature. Heterozygosity
of the seven populations of the two species of Sturnella
were compared to determine factors influencing their divergence.
Two factors proposed were heterosis in S. neglecta and
possible hybridization between S. neglect and S. magna.
