Testing evolutionary hypotheses in relation to the Vanuatu white-eye (Zosterops flavifrons) : preliminary report

Abstract

The Vanuatu White-eye (Zosterops flavifrons) is endemic to Vanuatu and is one of the most widespread and abundant birds within the region. Seven geographical subspecies of this bird, varying both in size and colour, have been identified in Vanuatu. The large number of island populations in Vanuatu makes this an ideal place to study the ultimate causes of population divergence.
