Chris Izworski's daily Michigan birding report turns to Allegan County this morning, where waterfowl congregations are building steadily through mid-October and late-season warblers continue to trickle through residential areas. The past fourteen days have produced 114 species across 114 observations, a solid showing for this stage of fall migration in the southern Lower Peninsula.
Waterfowl and Waterbird Activity at the County's Key Sites
Bonaparte's Gulls remain the dominant count in the county, with 68 individuals reported at the Kalamazoo River mouth over the past two weeks, most recently on October 9. That concentration is worth a visit if you're working regional gull identification or simply want to confirm the species composition in that setting. Equally significant, Sandhill Cranes have staged 29 individuals at 11th Street lake, with the most recent sighting dated October 13, suggesting the birds are holding in the area. Wade's Bayou Park has been productive for waterbird variety: Double-crested Cormorants number 20, Mute Swans 13, and Mallards 12, all observed within the past four days.
Blue-winged Teal appear to be lingering longer than usual this year, with 14 recorded at Pratt Lake near Shelbyville as recently as October 12. Wood Duck numbers stand at 15, last seen October 10 at the Mildred A. Peterson Nature Preserve. These dabbling ducks are moving through, and the relatively mild temperatures forecast for today (67 degrees, light northeast wind) may slow any mass departure that a cold front would otherwise trigger.
Late Warblers and Resident Passerines
The notable sightings flagged in the past fourteen days center on a cluster at 304 McVea Drive in Douglas. A Magnolia Warbler appeared there on October 12; Ruby-throated Hummingbirds showed on October 11 and 12; and a Rose-breasted Grosbeak was present October 11. A Bay-breasted Warbler was recorded at the same address on October 9. These are the birds birders should be pursuing if they're targeting late warblers. Two separate Tennessee Warbler reports came in on October 11, location listed as "home," so coverage elsewhere in the county may be incomplete. A Yellow Rail, an always-welcome find in October, turned up at South Plainwell on October 9 and warrants follow-up effort if the bird is still present.
Resident and short-distance migrants are consolidating. American Goldfinches number 12 at the Outdoor Discovery Center as of October 13. Dark-eyed Juncos and Cedar Waxwings both show 10 individuals at Farr's Yard, also October 13, indicating typical fall landfall activity. White-crowned Sparrows (5 birds, October 13 at Farr's Yard) and American Golden-Plovers (6 birds at 11th Street on October 13) round out the transient passerine picture.
Conditions and Hotspot Recommendations
Today's forecast offers a narrow window: partly sunny skies, northeast winds at 3 to 7 miles per hour, and negligible rain chance. Sunrise is 7:53 a.m., with the dawn chorus window running from 7:23 to 9:23 a.m. The mild temperature and calm conditions favor early morning effort, though the northeast wind is not optimal for pushing new birds into the county. Showers and thunderstorms arrive tomorrow afternoon, which may disrupt movement or concentrate birds temporarily.
Allegan State Game Area, particularly the Farm Unit, remains the county's most reliable hotspot for species diversity (248 species all-time). Wade's Bayou Park, given its current waterbird density, deserves priority if you're targeting the gull and cormorant activity. The Douglas area (around 304 McVea Drive) should hold birders' attention for any remaining warbler vagrants, though these sightings are sporadic and not guaranteed.
