Last Week
Chilly April is getting old, at least the sun was out and the trails were dry! Nineteen birders joined us to search for Meadowlarks and Palm Warblers last Sunday. No luck on the Palms, but plenty of Meadowlarks were singing. Highlights: Sora, Blue-winged Teal, Yellow-rumped Warblers, Field Sparrow, Eastern Towhee, and Wood Duck. As always for this time of year Tree Swallows, Eastern Bluebirds, Red-winfed Blackbirds, and Savanah Sparrows. Check out all 34 species on eBird list. Thanks to Katie for listing and David Baxter for grabbing some bird photos!

3-DAY FIELD TRIP: Southern Kettle Moraine to Wyalusing State Park

This trip is earlier on the calendar than in past years, but eBird recorded 20 warbler species at Wyalusing State Park by this date in 2025, and seeing the birds will be easier with the trees not yet fully leafed out.
On Wednesday, we will start the day in the Southern Kettle Moraine (exact meeting spot TBD), then make our way across to Prairie du Chien, have dinner at the Black Angus and overnight. We will make stops along the way to search for birds like Lark Sparrow, Upland Sandpiper, Louisiana Waterthrush. It’s an overnight Wednesday in Prairie du Chien. Thursday will see a pre-dawn start to bird Wyalusing for such specialties as Prothonotary, Kentucky, Yellow-throated and Cerulean Warblers. Later in the day birding east to overnight Thursday in Sauk City. Options late Thursday and Friday include Spring Green Preserve, Gov. Dodge State Park, Honey Creek Preserve and hotspots in Dane and Columbia counties.
Registration and details: Contact Gisela Zelenka-Drysdale, trip coordinator, giselazd@yahoo.com

Webinar: Birding at Lakeshore State Park
Thursday, May 7, 7:00-8:0 pm
The Friends of Lakeshore State Park, in collaboration with Milwaukee Birders and Audubon Great Lakes, are excited to host a Zoom about birding at the Lakeshore State Park!
Stephanie Beilke, Senior Manager of Conservation Science at Audubon Great Lakes, will show why the park is important for birds and the types of birds you may expect to see at the park at different seasons. She will also provide information about our monthly bird walks at the park, and present research data on a previous study about tree swallows found at the park, as well as touching some of Audubon Great Lake’s work in Wisconsin and on Lake Michigan.

List of Milwaukee area BIRD CLUBS !
Milwaukee parks that need birding this week
The county needs eBird records throughout the year for every park and natural area. Every week there are priority parks needing eBird lists. A park could be a priority because no surveys have been done for that week. Alternatively, it could be prioritized because there are surveys, but MKE Parks suspect more species might reside there than previously identified.
We can help MKE Parks! Pick a priority park, go bird, eBird it and note time spent there.
MILWAUKEE COUNTY PARKS : thru April 30
- Currie Park
- Dineen Park
- Dretzka Park
- Franklin Savanna (if you haven’t been and need access help contact Colleen at 414-379-6741)
- Grootemat Nature Preserve
- Kern Park
- Little Menomonee River Pkwy 2, 3, 4, 5, 6
- Menomonee River Parkway 1, 2, 3, 4, 5
- Milwaukee River Pkwy 1, 3, 5
- Oak Creek Pkwy 3, 4, 5, 6, 7, 10, 11, 12 (north and south) 13, 14 (for 12- no trails and for 13, there is no trail, and be VERY careful of property lines as private property is to both sides)
- Root River Pkwy 1, 3, 4, 6, 7, 8, 15, 16, 18 (no trails for 15, 16, 18)
Based on the needs spreadsheet from MKE Parks, Wisconsin Metro Audubon Society (Thanks Colleen!) curates suggested locations based on accessibility to the property and availability on the ebird hotspots tool. Please track your time spent! At the end of the year WMAS provides hours to the county.
Follow Wisconsin Metro Audubon on Facebook for their weekly park posts.
Note- even if it’s already been birded this week, going another day or even a different time of day helps. The parks department wants a number of surveys for each park. Birding more than once in a week is very helpful!
