📋 Research on Purple Martins shows that breeding latitude was highly associated with migration timing, explaining population-level differences across both spring and fall migration. Populations breeding at more northern latitudes migrated later in fall, in spring, and nested later than populations breeding at more southern latitudes. 💻 Learn more about Purple Martins on our website. www.purplemartin.org #PurpleMartin #ResearchShows #Science #Study #Migration #PMCA #Birds #Conservation #Research #BirdLovers
