Exploring Song As A Reproductive Isolation Mechanism In A Hybridizing Population Of Winged Warblers, Amy E. Janik
Masters Theses
Reproductive isolation mechanisms such as song are used by birds to promote assortative mating by species and prevent gene flow when closely related species come into secondary contact. Based on the strength of a reproductive barrier, signals in hybrid zones can diverge and become more dissimilar to maintain species or converge to become more similar and make species discrimination more difficult. When two closely related species overlap in territories and have similar songs, song convergence is likely and has the capacity to disrupt species recognition. We test the hypothesis that song acts as a reproductive isolation mechanism by examining song …
