This week on “Simply Superior,” we hear from James Paruk, author of a new book “Loon Lessons: Uncommon Encounters With the Great Northern Diver.” Paruk discusses the evolution of the common loon and his experiences studying them for several decades. We then extend well wishes and a radio goodbye to local music and arts producer and frequent show guest Daniel Oyinloye, who is moving to the Twin Cities. We end the program with a regional news in review, with WPR reporter Daniele Kaeding and Brooks Johnson of the Minnesota Star Tribune.
