Springtime at Ottawa NWR... The trees are starting to bud, the eagles are nesting, kinglets and towhees are making their appearances... But that also means THE BIRDERS ARE COMING!! We are gearing up for the spring migration season! The Biggest Week in American Birding, an event hosted by neighboring non-profit Black Swamp Bird Observatory will be the talk of the town. Ottawa NWR will be hosting part of the talks and presentations for the event, and we will have a full house throughout May.
