Light goose populations in North America have grown exponentially since the 1960s. The famed goose colony at La Perouse Bay, Manitoba, became the epicenter for studying this explosive growth and its damaging effects on Arctic ecosystems. In this episode, Dr. Mike Brasher is joined by special guests Drs. Rocky Rockwell and Tom Moorman to discuss the emergence of this issue, along with other topics including the evolution of white and blue phases of snow geese and their increasing hybridization. www.ducks.org/dupodcast
