With growing band recoveries and a newly implemented Breeding Population and Habitat Survey, waterfowl managers in the 1950s sought a more science-based understanding of population dynamics and harvest regulations. The 1960s brought plummeting waterfowl populations, reductions in harvest limits, declining hunter numbers, and shifts in waterfowl distribution. On this episode, Dr. Mike Brasher discusses these important changes and concerning times with Dale Humburg and Ken Babcock.  www.ducks.org/DUPodcast
