Chris Izworski's daily Michigan birding report turns to Manistee County this morning, where Arcadia Marsh continues to dominate recent activity with 100 Red-winged Blackbirds tallied over the past two weeks and consistent reports through yesterday. The marsh is functioning as expected for late June, with secondary numbers on Song Sparrow (20), Swamp Sparrow (10), and Sandhill Crane (10) all logged there. A Northern Mockingbird turned up at Arcadia Dunes Grasslands on June 23, which warrants a targeted check if you're working the county today; this remains a noteworthy sighting for the region.
What's on the Board at Arcadia
The marsh system is carrying the county's breeding season activity. Beyond the sheer volume of blackbirds, yesterday's visit logged Brown Thrasher at 11 individuals from Arcadia Dunes Grasslands, Field Sparrow at 8, Tree Swallow at 8, Common Yellowthroat at 6, Marsh Wren at 4, Common Grackle at 4, American Goldfinch at 4, and Indigo Bunting at 4. This reflects the typical late-June breeding assemblage for a healthy marsh complex in the northern Lower Peninsula. Mallards at 10 and Arcadia's 267 species all-time listing make it the clear focal point for any Manistee County visit.
Secondary Activity and Sparse Reporting
The eBird data from the past 14 days totals 122 species reported across 122 observations, which is thin coverage for a two-week window. Manistee River SGA holds 200 species all-time and should be worked, but no recent reports are flagged in the live data. Willamsport, Arcadia Lakeshore at Chamberlain Road, First Street pier, and Penny Park in Eastlake all sit on the hotspot list but lack current detail. The Ring-billed Gulls logged at Manistee Pizza Hut on June 26 is the only non-marsh highlight from secondary sites. This suggests either sparse observer effort or a genuinely quiet period in those locations.
Today's Weather and Timing
Mostly sunny conditions with 84 degrees and minimal southeast wind at 5 miles per hour make for a benign day. The real story arrives tonight and tomorrow: thunderstorms develop tonight into tomorrow, with temperatures climbing to 94 and wind shifting to 10 to 15 miles from the south. Breeding activity will be muted today given the heat and lack of overcast cover; dawn chorus peaked six weeks ago. If you're heading out, arrive before sunrise at 6:01 AM to catch residual singing before the day heats up. The south wind tomorrow could push some movement, but the storm chance makes tomorrow unpredictable.
Recommendation
Arcadia Marsh is the only location with fresh, repeatable data. Start there this morning before 9 AM and focus on the mix of marsh wrens, sparrows, and cranes in the wet areas. Work the grassland edges for Brown Thrasher if you haven't logged county birds recently. If the mockingbird is still holding at Arcadia Dunes Grasslands, it's worth the effort given its status as an uncommon summer bird for this region. Manistee River SGA is the secondary option if morning activity feels slow, though you'll be working without recent reports to guide you.
