I’m really excited to finally have this manuscript submitted for peer review and available on bioRxiv! We use direct re-sampling of a transect originally conducted in the 1950s to assess movement in the flicker hybrid zone over the past 60 years. We find ~73 km westward shift in the center of the hybrid zone, but no associated changes in width.
Check out the preprint to learn more! And definitely reach out if you have any comments!
