The fall warbler migration in Milwaukee, was what I would consider average. There were definitely some very cool birds, but the overall numbers were just okay and the weather wasn’t very good. Highlights of the fall were a beautiful male Kentucky Warbler (no photos) at Lake Park, 6 different Connecticut Warblers at multiple local parks, and several Mourning Warblers scattered around the local parks as well. 9/5 was my first big day with 17 warbler species. Two days later was my best day of the fall, with 24 warbler species, including my first of six Connecticut Warblers. I also had several Black-throated Blue, Golden-winged and Blue-winged Warblers. I couldn’t get out again until 9/13, if my memory serves me right, the weather was not very good that week. On the 13th, I had 18 warbler species, at Warnimont Park during the morning hours. That was also the day I saw the Kentucky Warbler at Lake Park. I didn’t get there until after 4pm, but I still had 21 warbler species there! The rest of the days were below average for me, with right around 10 warbler species. On 10/22 at Grant Park, I saw a late male Nashville Warbler and a week later at Grant Park, was a late beautiful male Pine Warbler. I ended the fall migration with 28 warbler species. Photos in the post are by specie and are from this year’s fall migration. I try to include males, females and hatch year birds and each photo is labelled. Enjoy!

  1. All the photos are stunning, but I particularly appreciate the Connecticut Warbler and Mourning Warbler photos. Those are the best I’ve seen for comparing the two species which can be confusing in fall since the immature Mourning has a partial eyeing and lacks the large black breast patch. Good work and thanks for posting!
