Dr. Mike Schummer, SUNY-ESF, rejoins the show with host Dr. Mike Brasher to provide a late season update on prevailing weather patterns in the eastern U.S. and how these have influenced waterfowl migration since the outbreak of cold weather in November. We wade into a discussion about large-scale atmospheric patterns that affect weather across the U.S. with a specific focus on the \u201cpolar vortex.\u201d The show concludes with advice on how hunters can adapt their strategies in the face of weather patterns that aren\u2019t conducive to strong bird movements. www.ducks.org/dupodcast
