A Sedge Wren showed up yesterday evening at the Fountain Custer Road corner in Mason County, a notably rare sighting that flagged immediately on eBird. This is the kind of find that makes late April worth getting out for in the Northern Lower Peninsula. The bird appeared at 8:16 p.m., which is not typical wren behavior, but migration pushes birds in unexpected directions and at unusual hours. If it lingers, it will be worth a targeted search this morning before the rain showers move in.
Migration is in full swing across Mason County right now, and the warbler pulse is noticeable. Yesterday brought multiple Black-and-white Warblers across the county: three at Best in the East, two more at the same location, and one at Ludington State Park. Rose-breasted Grosbeaks, a prize sighting in late April, made an appearance with two birds at Best in the East. A Western Meadowlark turned up at the Beyer Road area near Free Soil, another notable record for the county. These are the birds that make April worthwhile.
The waterfowl situation remains active. Ruby-crowned Kinglets are still moving through in good numbers, with 40 individuals logged at Ludington SP as recently as yesterday. Yellow-rumped Warblers dominate the warbler counts at 50 birds seen at Best in the East. American Goldfinches and Turkey Vultures are still present in significant counts: 35 goldfinches and 15 vultures at Best in the East. Shorebirds are working the muddy margins now; Greater Yellowlegs hit 20 at the Beyer Road fluddles on April 27, with 10 Lesser Yellowlegs at the same location. Blue-winged Teal are staging at Freeman Road ponds in groups of 10. The American White Pelicans that moved through earlier in the month have mostly cleared, but 17 were still at Ludington SP on April 22.
Today's Weather and the Morning Light
Rain showers are likely today with a 69 percent chance and temperatures holding around 51 degrees. The wind will stay light, 6 to 10 mph from the north-northeast. These conditions are not ideal for active birding, but they can push migrants to take shelter and make them more vocal. The real advantage comes in the next 36 hours: the frost tonight will clear into mostly sunny conditions tomorrow with calm winds. If the Sedge Wren is still on territory, tomorrow morning will be better for finding it. Sunrise comes at 6:40 a.m., giving a solid two-hour dawn chorus window before the sun gets high.
Where to Find the Action
Best in the East continues to deliver the most consistent activity, particularly for warblers and rare sightings. The Sedge Wren report from Fountain Custer Road makes that spot worth checking, though the wren's exact status today is unknown. Ludington State Park remains the county's most productive location with 271 species on the all-time list and strong recent activity across waterfowl, shorebirds, and migrants. The Beyer Road fluddles are still active for shorebirds if you want to work the yellowlegs and other waders. Freeman Road ponds remain reliable for dabbling ducks as they move through and stage.
The 156 species reported over the past 14 days shows solid spring activity for Mason County, though the count reflects scattered reports across multiple hotspots rather than concentrated pulses at any single location. This is typical for this time of year when migrants are spread across the entire county. The Sedge Wren is the headline story. Everything else is steady late April passage. Get out today if you can; check Best in the East and the Fountain Custer area, and plan a solid morning session tomorrow when the light improves.
