Chris Izworski's daily Michigan birding report looks at Antrim County this morning, where the past two weeks have produced 85 species across the Northern Lower Peninsula. The county is showing typical early August activity: Ring-billed Gulls dominating waterfront counts at Antrim Creek Natural Area with 55 individuals through July 31, Purple Martins holding steady at 30 birds around Hofer Cottage, and a scattering of mid-summer residents and migrants trickling through the wetland and river systems.
What's Moving Through Antrim Right Now
The data from the past 14 days reflects August's particular rhythm in this region. Ring-billed Gulls anchor the top count, suggesting consistent loafing habitat at Antrim Creek, a reliable spot for waterbirds. Cedar Waxwings and European Starlings each scored multiple observations on US Highway 31 North near Ellsworth as recently as today, the kind of loose flocking behavior typical when fruit crops are ripening. Common Merganser reports from Alden (5 birds on July 19) indicate breeding birds lingering or early migrants not yet pushing south in serious numbers.
Warbler activity is beginning to shift into migration mode. Common Yellowthroat appeared three times at Grass River Natural Area through July 25, and while counts are modest, the species is right on schedule for fall movement. This is the time to watch for late warblers in worn plumage; many will be nearly impossible to pin down to subspecies or even species in some cases. Swamp Sparrows, also three sightings at Grass River, are another August fixture worth tracking as juvenile birds fledge out and begin moving through suitable habitat.
Hotspots and Recommendations for August 1
Grass River Natural Area continues as the top contributor, with 193 all-time species recorded. It delivered Red-breasted Nuthatch, Red-winged Blackbird, and the aforementioned warblers and sparrows in the past two weeks. Campbell Road wetland (155 all-time species) and Bellaire WWTP (145 all-time) are worth checking if you're mobility-limited or want to focus on shorebirds and waders, which should be peaking now. Antrim Creek Natural Area, despite being lower on the all-time list, is clearly active right now with gull concentrations and Double-crested Cormorants.
The weather forecast shows 47 percent rain chance today with temperatures reaching 75 degrees. Tonight's lows near 58 will be warm enough to encourage activity. Tomorrow looks cleaner: mostly sunny, 76 degrees, and a light northeast wind developing. If you're planning an outing, tomorrow morning may offer better conditions, especially given the long day length; sunrise is 6:25 AM and the dawn chorus window extends from 5:55 to 7:55 AM. The calm conditions this evening could also trigger nighthawk flights, a possibility in early August when conditions are right.
Overall Assessment
Antrim County is neither slow nor exceptional at the moment. The 85 species reported over two weeks is solid baseline activity for the season. No rare or notable sightings have been flagged by eBird, so this is steady-state August: resident species, local breeders, and the earliest trickle of fall migrants. The county's major wetland systems, particularly Grass River and the creek corridors, remain the draw. Purple Martins are still in reasonable numbers at Hofer Cottage, though these birds will be departing soon. Chimney Swifts reported at Bridge Street in Bellaire (10 individuals on July 24) are another species to note as populations thin through August.
If you are heading to Antrim County today or tomorrow, Grass River Natural Area remains the best bet for species diversity and recent activity. The wetland habitat there is excellent for warblers, sparrows, and the occasional unexpected transient. Check the margins where woodland meets cattail marsh; that is where the most interesting early migrants typically appear.
