You can learn about the most visible bird along the shoreline of Door County this coming week. Staff at Crossroads at Big Creek in Sturgeon Bay have been documenting bird migration at the Cove Estuary Preserve for the past month. On Thursday, October 13, Dr. Ray Faber will present his program, “A Century with Herring Gulls.”  He will discuss his research to understand better the herring gull population and their challenges in reproducing. Kathleen Harris of the Ephraim Historical Foundation will open the evening by speaking about the ground-breaking work Harold Wilson did on Strawberry Island near Ephraim. This free event is open to the public and is offered in conjunction with the Ephraim Historical Foundation. Dr. Faber is presenting the same program earlier on Thursday, from 1:00 – 2:00 p.m., at the Ephraim Town Hall. The presentation at Crossroads at Big Creek will be in the lecture hall of the Collins Learning Center and will start at 7:00 p.m.
