It is likely that the Fall issue also will be delayed as the WSO Board searches... Read More   

Late Migration Brought Great and Abundant Rarities

It was a cold and wet month that triggered a late migration. The first big warbler waves were behind schedule this May with many areas not seeing a good flight until May 15. Once the dam finally burst there was a steady stream of migrants through the Memorial Day weekend. Some great rarities were reported and some species were seen in unprecedented numbers. The state's second Hooded Oriole was... Read More

Wisconsin’s Peregrine Falcons: A Spring Update

-By Greg Septon-  Many Peregrine Falcons in Wisconsin overwinter and those that do generally get a head start on the nesting season. Such was the case again this year with the first eggs of the season laid on March 26 and continuing on a regular basis through April 16. Of the 30 or so nest sites I monitor, there were a total of 80 eggs under incubation at 21 sites by mid April with... Read More

White River Marsh Field Trip Report – 2019

It was a chilly but nice morning on May 4 at the White River Marsh, as birders began gathering prior to 5:00 AM.

Jupiter and Saturn were on full display in the still-dim southern sky, and a number of us enjoyed views of both of them through a scope. All around us, the dawning marsh... Read More

In the January issue, it was noted that the Madison Bird Club had in mind a statewide bird club. The... Read More
