May 19, Saturday, All Day, BERRIEN COUNTY’S ANNUAL BIRDATHON. Birdwatchers from all over Michigan will spend the day searching to see as many bird species as possible. Teams from Sarett will be trying their skill and luck. This event has become a very important fundraiser for the nature center. Each team’s members find sponsors who pledge for each species seen that day. If you would like to sponsor a team, please call Sarett. If you would like to join a team or form your own team, please give us a call.
