Recent News

The Fall Meeting planned for late September/early Ocotober in Centerville has been canceled. We'll hold an IOU Big Weekend September 26-27 to find as many bird species as possible in the state. A page will be added to the website that works like the County Checklists page. IOU members can enter the species they see in each county and a total will be calculated. Our goal is 200 species. Plan to do some safe birding that weekend and have fun out there!
