Monarch Migration Happenings
Monarchs are making their way to overwintering locations! For the Eastern population, the first peak migration event was reported in Mexico. For the Western population, every Western state posted new sightings over past two weeks.
Migration Happenings
It's hard to keep up with all the migration happenings.
The Eastern population of monarchs: From peninsulas to coastal ports, Journey North volunteers are documenting monarch roosting behavior. Early in September, monarch roost numbers kept increasing along the shores of the Great Lakes. Mid September, volunteers observed roosts in the central U.S. This week, volunteers are observing roosts in Texas. Along the Atlantic Flyway, the Delaware Bay and the Chesapeake Bay continue to be hotspots for roost activity.
Worries about the impact of extreme weather events abound.
The Western population of monarchs: Journey North volunteers are reporting monarch activity across all Western states.
