Since I’m spending the last two weeks of October in Hawaii, the fall warbler migration is over for me. It turned out to be a very good one, with it starting earlier than normal for me. I had huge numbers of birds beginning very early in August (8/10) through the end of the month. My guess is it had something to do with the wildfires in Canada. I was pretty busy in August, so I had limited chances to get out. Because of this, I missed out on some fall birds, including my favorite, the Canada Warbler. I spent all of my time at Warnimont, Grant, Sheridan and Bender Parks this fall. I ended up with 25 species of warblers this fall. September started off very good for warblers, but then we got some terrible weather patterns for the next few weeks and had one major migration day after that, which I wasn’t available for. I was able get the two late passerines, Pine and Orange-crowned Warblers, just before I left. I would have been upset if I didn’t see either of those. It will be a long, cold winter waiting for the colorful little birds to return. Hopefully the owls cooperate in the cold months! The photos below are from early August through the middle of October, when I left. Fall warblers have so many variations of plumages. I try to capture as many as possible to show what you might see when out. The individual photos are labeled male, female or hatch year, if you click on them. Enjoy!
’23 Spring Warbler Migration
Despite having terrible weather conditions in May, to produce huge numbers of warblers, I still ended up with 36 warbler species. I just didn’t have very many big days, like I’m used to. We were stuck with E, NE or N winds for the majority of the warbler migration, thanks to our “great” Lake Michigan! Of the 36 warblers, 35 of them were in Milwaukee County. The lone one outside of Milwaukee County, was a Painted Redstart that showed up in Sauk County. I missed one, a Black-throated Gray Warbler that made an appearance at Wind Point Lighthouse in Racine, and only because I was busy that day. Most of the county parks were just average at best. Warnimont Park was producing rather solid numbers most days, like usual and is still my favorite spring warbler park. One little gem, that was basically the county hotspot, was Shorewood Nature Preserve. This tiny little park, nestled between a couple mansions in Shorewood, hosted some great birds including, Worm-eating Warbler, Cerulean Warbler, multiple Yellow-throated Warblers, Prairie Warbler, multiple Hooded Warblers, and a Louisiana Waterthrush. All of those warblers are great for the county. Lake Park hosted a couple of Connecticut Warblers, like it usually does. Warnimont Park also a had several, however viewing is better a Lake Park for them. This is a very large gallery of photos, but warblers are my favorite and I spend a lot of time with them in the spring. As always, I try for male and female, along with first spring birds, to show the varying plumages between them. It’s tough to get them all though. All of the photos below are from Milwaukee County, with the exception being the Painted Redstart. Enjoy!

Worm-eating Warbler, Northern Waterthrush & Ovenbird in May ’22
Worm-eating Warbler is uncommon in Wisconsin. However, I think Milwaukee County has gotten one the last several years. This year I saw two! One was along a creek at Whitnall Park (5/9), and the other was singing at Warnimont Park (5/15) in the wooded area, east of hole #6. I was able to track down the one at Warnimont and sneak quietly within 25′ of him. I watched him eat spiders, caterpillars and midges, and was also constantly singing. The song is a dry, almost insect-like trill, similar to Chipping Sparrow. It was very hard to get wide open views of him though, as he stayed very low and in patches of thick brush. I still managed decent photos considering the thickets and it was the first time I was able to get one singing, which I love. Northern Waterthrush & Ovenbird are very common in Wisconsin, especially in Milwaukee County during migration. On 5/1, I had 10 Northern Waterthrush and 9 on 5/10, both at Whitnall Park. They can be found anywhere near any kind of water. They are usually singing throughout the entire day. There are many variations of the song, but for the most part it is a loud, ringing, three-part sweet sweet sweet swee wee wee chew chew chew chew. I find that they are very skittish, unless you’re standing still, and they fly and land near you. As soon as you move though, so do they. As for Ovenbird, I had 7 on 5/9 and 6 on 5/10, both at Whitnall Park as well. Ovenbird is found walking the forest floor, picking through leaves and downed branches, looking for insects. They sing a rather loud song, starting quieter and getting louder with each note. It is a rapid, resounding tea-cher, Tea-cher, TEA-cher, TEA-CHER. The photos below were taken in May. Enjoy!
