The 7:00 AM temperature on Saturday, March 24 was only slightly below normal, in the upper 20s, but the very strong east wind really brought the “feels like” temperature down – into the single digits!  The tough wind chill likely kept the attendance down this year, since we only had around 20 hardy birders show up for this outing. The field trip attendees gathered at... Read More   

Our group of 14 recently returned from our 2018 WSO Costa Rica Tour (Feb. 25 to March 10), after another fabulous tropical adventure! Eleven of us flew together from Milwaukee, via Houston, and met three other participants flying in from elsewhere. After driving south from the airport, our tour started out near the Pacific Coast, at a lodge not far from Carara National Park. We spent most of our... Read More   

There is a statewide advisory question all bird enthusiasts should weigh in on at the April 9th Wisconsin Conservation Congress spring hearings. It relates to banning the use of neonicotinoid insecticides on state owned agriculture and forest land. While neonics are effective against various insect pests, they also kill non-target insects, including many pollinators, along with having significant... Read More   

This year the field trip attendees gathered at the Buena Vista Grasslands kiosk along Hwy. W, around 8:00 AM.  The weather was unusually mild, with a starting temperature of about 30 degrees.  The sky was partly cloudy, the winds were light to moderate, and there was very little snow on the ground.  We had no trouble with snowdrifts and impassible roads this year!  There...

Save the date! And please watch the Badger Birder and the websites of the Wisconsin Bird Conservation Initiative Read More   

WSO has joined forces with other funders to support the electronic tagging of as many as six Snowy Owls in Wisconsin this winter as part of a multistate effort known as Project SNOWstorm. More than 50 owls have been tagged in 10 states from North Dakota to Maine since 2013. WSO earlier funded transmitters for two of the six owls tagged in Wisconsin during previous winters -- for a bird known as... Read More   

There will be a couple of new twists to this year’s Honey Creek Birdathon/Bandathon weekend. Place a hold on your calendar for the weekend of May 12-13. Both the birdathon and bandathon will take place at WSO’s Honey Creek Nature Preserve on Sunday May 13, rather than holding them over both days.  But we’re resurrecting the once-popular Saturday evening campout for those who...

As expected, the temperature was bitterly cold (starting at 2 degrees), just has it has been for the past couple of weeks.  Participants started gathering at South Shore Yacht Club a little before 8:00 AM, and many took the time to add a layer or two of warmer insulation before joining the group.  The attendance today (1/6) was greatly limited by the cold conditions, and there were only...
