Saturday, May 18th, 2002 the Riveredge Bird Club held its 14th Annual Birdathon/Bandathon. The Birdathon portion of the event identified 107 species of birds on the Riveredge property. The Bandathon portion set a record, capturing and banding 201 birds representing 39 species. Thanks to Everyone who helped with the birind and banding. It was certainly a wonderful day to be birding at Riveredge Nature Center.

The forecast Friday was for very cold overnight temperatures including frost warnings. Saturday was to be cool with rain in the afternoon. We had to scrape frost off our car to go to Riveredge. Rather than starting at 5AM we started at 6:30. Due to the cold we checked nets every 10 minutes in the early morning. The hummingbirds we captured as well as the warblers and other birds all seemed to be doing well with the cold weather.

The warblers at the river were often at eye-level, seldom higher than 20 feet in the trees. I had heard about birding like this, but never experienced it. At one point Saturday we had 27 birds in one net (all removed and handled without any harm).

Two Banding Stations

We had enough people to run two banding teams and banded in two different habitats, one along the bank of Milwaukee River and the second farther inland near ponds, a stream, and prairies and wet meadows.
