Differences in seasonal migration might promote reproductive isolation and differentiation by causing populations in migratory divides to arrive on the breeding grounds at different times and/or produce hybrids that take inferior migratory routes. We examined this question by quantifying divergence in song, colour, and morphology between sister pairs of(More)
Elucidating the relationship between genetic and cultural evolution is important in understanding speciation, as learned premating barriers might be involved in maintaining species differences. Here we test this relationship by examining a widely recognized premating barrier, bird song, in a hybrid zone between black-throated green (Setophaga virens) and(More)
Areas where divergent taxa come into secondary contact are important in identifying the reproductive barriers that may have evolved between them. Here we investigate whether song variation plays a role in maintaining a recently described hybrid zone between MacGillivray's (Oporornis tolmiei) and Mourning War-blers (O. philadelphia) in northeastern British(More)
