Chris Izworski's daily Michigan birding report turns to Otsego County this morning, where 97 species have been logged over the past two weeks and the transition into late fall migration is well underway. The county is showing the typical October mix of lingering summer breeding birds, arriving winter residents, and waterfowl numbers climbing as fronts push through. This is a working landscape in the northern Lower Peninsula, and the birds reflect that reality.
What's Moving Through Right Now
Morgan Road farm ponds continue to be the reliable waterfowl staging area. The most recent count from October 3 documented 20 Canada Geese, 9 Mallards, and 7 Ring-necked Ducks, all viewable from the road. Six Sandhill Cranes were also present at the same location on October 3, which is worth watching for if you're working that area. The ponds hold steady as the primary attraction for dabbling ducks and diving ducks building up for the push south.
South Otsego Lake marsh showed 7 American Herring Gulls as of October 2, along with the Ring-necked Ducks noted above. Lake-based birds remain scattered in early October; counts will build as the month progresses and deeper cold arrives.
Passerines are still moving. Otsego County Demonstration Garden has been the most active reporting site with 66 European Starlings, 14 Turkey Vultures, 9 White-throated Sparrows, and 6 Chipping Sparrows as of October 3. The Vanderbilt Vines Winery area turned up 10 Horned Larks and 6 Dark-eyed Juncos on the same date. Juncos are establishing themselves now; expect them to increase through the month.
Notable Late Birds and Rare Sightings
The flag list carries some interest. An Indigo Bunting was reported twice at Aspen Park on September 27, and again at a Gaylord location on October 1. Late buntings are always worth checking if you're in the area. A Red-eyed Vireo lingered at Stowe Lane in Gaylord as recently as October 2, which is getting late for that species but not unprecedented in a warm fall. Most significantly, a Rose-breasted Grosbeak was documented at Pigeon Bridge State Forest Campground on September 28. Groseaks typically clear out well before October, so that bird was either delayed or may have already moved on.
Two flycatchers were noted at Aspen Park on September 26: a Least Flycatcher and an Olive-sided Flycatcher. Both species are on the tail end of their migration window; early October records are possible but not common this far north. Aspen Park has consistently productive conifer habitat and is worth checking if you're targeting late migrants and winter residents like Pine Warblers, which have been recorded there.
Weather and Conditions for Today
Today's forecast shows 61 degrees with isolated rain showers and a 15-mph westerly wind; rain chance sits at 18 percent. Tonight will drop to 37 and clear partly, setting up tomorrow nicely at 55 and mostly sunny with lighter winds. A light westerly flow right now does not suggest any major movement is imminent, but the cooler overnight tonight and tomorrow's clearer conditions may push a few more birds through, particularly if you're out early. Sunrise is 7:38 AM with the dawn chorus window closing by 9:08 AM; this time of year the window is short enough that early mornings are essential.
Where to Focus Today
Pigeon Bridge State Forest Campground remains the top hotspot in the county with 164 all-time species and recent records including that Rose-breasted Grosbeak. If late migrants are still lingering, that's where diversity will show. The habitat around the campground is reliable year-round. Alternatively, if you want to work waterfowl and cranes, Morgan Road farm ponds offer viewable birds from the car without trespassing; the recent Sandhill Crane activity there makes it worth the drive. Both hotspots have performed well this past two weeks.
October 4 is neither a peak movement day nor a slow day in Otsego County. The data shows solid diversity across 97 species in 14 days, which is respectable early-month activity. What's here is here; what's moved on has moved on. The county is between seasons rather than in the midst of one.
