Saturday was the Wisconsin spring bird count. That meant that almost every birder in the state was out and about seeing what species they could find. Lucky for all of us it turned out to be one of the most beautiful days of the year thus far with temperatures in the high 70s.
I met up with Bill Grossmeyer at Lion’s Den Gorge in Ozaukee County to help out with the count. As soon as I arrived, bird calls were coming from seemingly every direction and small shapes were moving around in the tree tops. We quickly picked out several warbler species including yellow, Black-Throated Green, Yellow-Rumped, and Palm. Also present at the start of the trail were Swamp Sparrows, Song Sparrows, and a single Lincolns Sparrow.
Farther along we encountered pockets of different warblers including Nashville, Black and White, and several singing Northern Parulas making their classic “zipper” call. We were also able to locate several Field Sparrows, Baltimore Orioles, an indigo Bunting, and one incredibly vocal Brown Thrasher.
We took five minutes out of looking for warblers to check out a more marshy area of the gorge. This proved to be a great decision as we found several White-Throated Sparrows, White-Crowned Sparrows, and buzzing Clay-Colored Sparrows. This area also had a singles Northern Shoveler and Ring-Necked Duck.
Our best find of the day came as we walked out of the marsh and back onto one of the more forested trails. suddenly a Cerulean Warbler popped up from some lower bushes and appeared no more than ten feet in front of us. Cerulean Warblers are not rare in all parts of Wisconsin but they can be difficult to find in many places. The bird gave us great looks as it fluttered from branch to branch calling.
After watching the Cerulean Warbler for some time we headed out to try some other locations around Ozaukee County. On our way out we encountered an Orange-Crowned Warbler and several Orchard Orioles. We also heard the teepa teepa teepa call of a Great Tit. As it turns out, this sighting is the farthest south recorded in Wisconsin.
When we finally left Lion’s Den, we found that there were not nearly as many birds in other areas sch as Coal Dock Park in Port Washington or the adjacent bike path. As a result, after about an hour and a half hiatus without picking up anything new but Common Terns, Forster’s Terns, and an Ovenbird we headed back to Lion’s Den Gorge.
Upon arriving the action immediately started up again with several Blackburnian Warblers near the entrance of the trails. In this same area we also got great looks at an Orchard Oriole.
After walking around for another hour, things started to slow down and most of the birds that had been moving around in the morning were suddenly gone. We decided to call it a day and headed back home, feeling pretty excited about the first really good day for warblers this spring.
