Promoting the enjoyment, study, and conservation of Wisconsin's birds.

The highlight of the birding year is the frenzy of spring migration, peaking in May. The array of sights and sounds is amazing as colorful Neotropical migrants return or pass through on their way north. Adding to the excitement of this color and diversity is the chance that some mega-rarity will show up way out of range. This happened several times last month. The highlight occurred on Saturday,...

Most of the 14 participants in WSO’s 2016 tour to Costa Rica, led by Tom and Wendy Schultz, met in Milwaukee on the evening of Feb. 24 and flew out at 5:55 the next morning. After a stopover in Atlanta, we arrived in San Jose around 1 p.m. and met our guide, Kevin Easley, loaded our gear onto our coaster bus, and were off –- surrounded by the new sights, sounds and birds of Costa Rica! The... Read More   

A few weeks ago in a valley not far away… an early-rising Swamp Sparrow became the first bird tallied on the 2016 Honey Creek Birdathon. It was 3:17 a.m. and the full moon cast long, clear shadows; perhaps the sparrow was an insomniac or simply confused. While the Swamp Sparrow was not an “exciting” bird, it was a harbinger of things to come -– a lot of the expected species, and not a lot... Read More   

There was a bit of orange glow in the eastern sky as we gathered around 5:00 AM on May 7, but for the most part the sky was pretty cloudy. The temperature was fairly moderate, but there was a stiff wind blowing out of the north, which made it a little more challenging to hear the bird sounds around us. Not far away an American Woodcock was peenting and doing his flight display, and a Wilson’s... Read More

This season’s warm weather has prompted many migrants to take flight earlier than usual. A few species, like Greater Yellowlegs, Lesser Yellowlegs, and Franklin’s Gull, have been reported this year at the earliest dates on record, and many species are running a few weeks ahead of schedule. If you’re eBirding, these early migrants might be wreaking havoc on your reporting. If your records... Read More   

As the heart of spring quickly approaches we longingly look forward to the return of the neotropical migrants. Many of us have been doing so for years -- trying to free up time in mid-May to get out and experience the color and variety of the wonderful birds that have been wisely down in the tropics since last fall. Absence does make the heart grow fonder, and it reminds me how important it is... Read More   

This year marked a new and earlier start time- 7:00 AM- for this popular field trip. We had decided to try an earlier meeting time because in the past we had noted that many geese had flown out from the flooded fields where they had been present just an hour before- and the new starting time appeared to work well for that reason! There were about 40 enthusiastic birders present at the Goose... Read More   

On Sunday March 6, 42 people assembled at the Sheboygan Marina at about 8 AM, for WSO’s annual spring lakefront field trip. The weather was fairly pleasant but the moderate winds put a bite to the air. So hats, gloves and a heavy coat were in order. Within the Sheboygan Harbor and river channel we found 25 species. From the marina we had scope views of 2 Adult Great Black-backed Gulls and a... Read More
