Impressive Numbers of Monarchs Witnessed
Watch the migration unfold on Journey North.
From the Great Lakes region to South Dakota, Nebraska, Idaho and even Colorado, Journey North citizen scientists are witnessing impressive monarch roosts. Journey North observers are also reporting large numbers of migrating monarchs. A large exodus of monarchs is happening right now as monarchs roost along shorelines and traverse the skies on their way to Mexico. Take a moment to view the many wonderful photographs and videos posted to the Journey North monarch migration maps.

From Clearville Park, ON: Steve estimated, “15,000 butterflies per hour flying at various altitudes above the bluffs on Lake Erie’s north shore…all flying in the same direction – southwest towards Pt Pelee…For two, 10-minute periods, I count as many as I can see…compare the totals for each period and continue observing throughout the hour to see if the rate changes. I then used this information to estimate hourly totals.” (09/08/2019) Read the full report
