Monarchs are famous for the dramatic journey they make each autumn through eastern North America to their winter roosts in Mexico. Louise Zemaitis, field coordinator of the Monarch Monitoring Project in Cape May, New Jersey, has been studying these butterflies for the past 25 years. In this lecture she described the natural history of Monarchs, their migration, and the work being done to further our understanding of these amazing butterflies.

The presentation was part of The Biggest Week in American Birding. The lecture was at Maumee Bay State Park.
