What's Moving Through Kalamazoo County Right Now
Chris Izworski's daily Michigan birding report turns to Kalamazoo County this morning, where fall migration is pushing warblers and sparrows through in steady numbers. The past 14 days have yielded 138 species across the county, with Bay-breasted Warblers showing up at the Kalamazoo Nature Center in the last week. That's the real signal right now: the warbler wave is still on, and small reserves are catching birds daily.
Beyond the migrants, Kalamazoo is hosting its usual cast of late-summer holdovers. Chimney Swifts remain common at Twin Lakes with 12 individuals noted as recently as September 3. Sedge Wrens are persisting at Asylum Lake Preserve, where 7 were logged on August 31, suggesting the marsh there is holding breeding birds or early migrants. Ring-billed Gulls continue to loaf at Fort Custer SRA with 12 seen on September 2. The waterfowl picture is modest at present: 13 Mute Swans at Twin Lakes, 10 Canada Geese at Cranes Pond neighborhood, and a handful of Great Blue Herons working the usual spots.
Notable Records and Recent Sightings
The flagged sightings from eBird warrant attention. A Willow Flycatcher turned up at the Kalamazoo Nature Center visitors center on September 3, which is a reasonable late-summer record for the county. White-throated Sparrows have made multiple appearances at Gourdneck SGA Hike in late August, suggesting they are beginning their southbound push earlier than usual. A Red Phalarope at Stafford Farms pond on August 21 is the kind of inland vagrant that makes Kalamazoo County worth working; those records cluster around bigger water bodies and agricultural wetlands when conditions align.
Weather and Movement Patterns
Today's forecast calls for 88 degrees with a 44 percent chance of showers and thunderstorms, winds light at 3 to 7 mph from the southeast. Tonight turns wet, with rain likely, and temperatures dropping to 67. Tomorrow improves with a high of 81, northeast winds, and decreasing precipitation chances. That SSE flow today is marginal for pushing additional warblers northward, but it's sustaining the current wave. The overnight rain may ground birds, making Saturday morning's dawn chorus window, 6:39 to 8:39 AM, potentially productive if skies clear. The northeast wind tomorrow should bring fresh birds through weedy edges and marsh margins where Sedge Wrens and sparrows concentrate.
Where to Bird Kalamazoo County Today
Fort Custer SRA and Kleinstuck Preserve are the logical choices for a Friday outing. Fort Custer's 216 all-time species make it the county's top hotspot, and gulls and herons are reliable there. Kleinstuck Preserve, with 211 all-time species and its mix of woodland and wetland, is better positioned to intercept migrants in this season. The Kalamazoo Nature Center visitors center has proven productive for warblers this week, so if you are in town proper, that is a low-commitment option.
Asylum Lake Preserve deserves a dedicated visit if you want to nail down the Sedge Wrens before migration clears them out. That preserve is producing, and the species is worth the effort.
