After providing an overview of the patterns and processes driving crossbill (Loxia) diversification, I will focus on the premating reproductive isolating barriers contributing to speciation in crossbills. Crossbill are interesting in this regard because many crossbill taxa have diverged recently (<11,000 years ago) and have likely diverged with gene flow. I will emphasize assortative flocking behavior, because crossbills flock year round and choose mates from within flocks, and because high levels of assortative flocking can evolve as a barrier to gene flow without geographic isolation.

Everyone is welcome to the seminar. If you would like to meet with the speaker, please email Dr. Brian Buma at brian.buma@ucdenver.edu
