To advance the conservation of birds and bats in Wisconsin and throughout the Western Great Lakes Region through coordinated research, monitoring, and education.

Today more than ever, we are certain of two things:

1. That people like you can make a real, beneficial difference to the birds and bats of Wisconsin and the Western Great Lakes Region 

2. That one of the best ways to do this is by supporting the Western Great Lakes Bird and Bat Observatory

We had an exceptionally productive year in 2018, our first as an independent non-profit organization.
