Chris Izworski, reporting from Michigan, turns to Isabella County this morning with the county in the thick of fall migration. One hundred one species have moved through in the past two weeks, and the usual suspects are holding, but the weather today may shift what shows up by evening.
Warblers Still Present at Mill Pond Park
Mill Pond Park remains the focal point for migrant warblers in Isabella County. Bay-breasted Warblers hit seven individuals as recently as August 31, and Black-throated Green Warblers were at seven as well on August 30. Magnolia Warblers checked in at four on the same date. These birds are still moving through, and the dawn chorus window from 6:33 to 8:33 AM is your best window before the forecast chance of showers kicks in around midday. The 39 percent rain chance and WSW wind at 3 to 9 mph is not ideal for holding migrants in place, but the overcast conditions may keep birds active longer than a clear morning would.
Waterfowl Concentrated on the County's Southern End
Wood Ducks are showing eleven individuals at the Fremont area site on S Nottawa Road as of September 1, and Canada Geese are at eight on the same location. This southern hotspot, well away from Lake Isabella itself, has been productive for water birds through the late summer transition. The calm winds and morning conditions may keep these birds on the water longer before they disperse into feeding areas.
Resident Passerines and Upland Birds Holding
Red-winged Blackbirds continue to dominate the count at Mill Pond Park with fifteen individuals recorded through August 29. Wild Turkey sightings hit nine birds on September 1 at the Riverside Drive location in Mount Pleasant, suggesting local flocks are stable and moving through residential edge habitat. Cedar Waxwings, always mobile in September, show five at the Fremont site. House Finches are steady with eight at Riverside Drive. These are birds that breed locally and remain through the season, so they anchor the daily count even as the transient warblers rotate through.
Barn Swallows Staging for Departure
Seven Barn Swallows were reported at Lake Isabella on August 31. Swallows typically stage in loose flocks before making long flights south, and Lake Isabella's open water and insect productivity make it an obvious staging ground. Watch for larger aggregations as the month progresses, particularly around dawn when insects become active.
Eastern Meadowlarks on Valley Road
The Valley Road corridor from Summerton Road to Leaton Road showed five Eastern Meadowlarks as of August 19. This species is declining statewide and any sighting warrants documentation. The data is now two weeks old, so this hotspot may be worth revisiting to confirm birds are still using the area.
Where to Bird Isabella County Today
Mill Pond Park and the Fremont area on S Nottawa Road are your priority targets. Mill Pond Park delivers the warbler activity and will be most reliable for the full suite of migrants still working through the county. Arrive early before the clouds thicken and rain chance climbs. The Fremont site offers waterfowl and some passerine diversity in a more open setting. Lake Isabella rounds out the county's three tier-one hotspots and has a 183 all-time species total, but the eBird activity there has been quieter in recent days. All three are solid choices depending on your focus.
Today's weather is workable for early morning birding. The 87-degree forecast and 39 percent rain chance mean you want to be out by 7:00 AM and plan to be off the water or under cover by early afternoon. Tomorrow shows rain showers lingering into the morning, so today is the better option.
