Plumage assisted divergence in a vocally complex island endemic: The Dicrurus paradiseus species complex in Sri Lanka
Models of allopatric speciation within an island biogeographic framework suggest that the division of ancestral mainland populations leads to one or more allopatric island species predominantly through natural and sexual selection or genetic drift.Here we studied phenotypic divergence in a phylogenetic framework in the Dicrurus paradiseus allospeci
