Chris Izworski's daily Michigan birding report turns to Roscommon County this Sunday morning, where post-breeding season activity is settling into its characteristic midsummer rhythm. The past two weeks have yielded 114 species across 114 observations, a solid return for this stage of the calendar in the northern Lower Peninsula. The data tells a clear story: this is waterfowl and marsh country right now, with swallows working the airspace and breeding warblers growing quieter by the day.
Trumpeter Swans and the Houghton Lake Complex
The standout finding remains a small gathering of Trumpeter Swans at Houghton Lake Sewage Ponds: 10 individuals as of July 7. This is the county's premier hotspot overall with 225 species on the all-time list, though access is limited to weekdays 8 a.m. to 4 p.m. The same location turned up 4 Lesser Scaup on that same date, a more typical finding for this late-summer period. The sewage ponds remain your best bet for lingering waterfowl that have not yet fully dispersed to open water.
Houghton Lake Flats Flooding, the second-ranked hotspot in the county with 206 all-time species, is showing more activity in recent days. Cliff Swallows have been the dominant story here: 12 individuals reported, most recently on July 8. This is classic late-July behavior as breeding birds begin to gather on wires and over the marsh. The same location has also held Green Heron (6 birds), Canada Geese (6), and European Starlings (6). The diversity is modest but typical for the season.
Warblers and Songbirds at Backus Creek
Backus Creek State Game Area is showing the best recent activity for breeding songbirds. July 15 brought reports of six species in reasonable numbers: Black-capped Chickadee, Cedar Waxwing, Red-eyed Vireo, and Ovenbird all at six individuals each. Pine Warbler (4) and Red-breasted Nuthatch (4) were also noted. This site ranks fifth on the county hotspot list with 165 all-time species. The presence of Ovenbirds suggests functional territory occupancy; these birds are typically underreported by casual observers.
Marguerite Gahagan Nature Preserve produced a notable finding on July 12: one Golden-winged Warbler on Rd 602, a species that warrants documentation in Roscommon County. The preserve also holds Mourning Warbler (4) and Red-breasted Nuthatch (4), placing it solidly on the radar for breeding songbird work during the remaining window before birds move out or stop vocalizing entirely.
Common Loons and the Lake Circuit
Higgins Lake is producing Common Loons: five individuals as of July 15. These are likely non-breeding birds holding over or early returnees beginning their southbound movement. Higgins Lake itself is a major water body in the county, and systematic coverage of its shores and the surrounding road network can yield waterfowl, herons, and occasionally shorebirds as migration advances into late July and August.
What to Target Today
The weather today and tomorrow will not complicate birding. Patchy smoke is forecast for both days, likely from western wildfires, but visibility should remain adequate. Temperatures will climb to 77 today and 81 tomorrow, with wind minimal to light. The calm conditions mean early morning activity should be worthwhile if you are willing to move before 7:30 a.m. to catch the latter end of the dawn chorus. Shorebird migration is beginning in earnest in mid-July across Michigan, so any time spent scanning the shallow edges of marshes and ponds may yield early arrivals.
If your schedule permits access on a weekday morning, the Houghton Lake Sewage Ponds remain the highest-value hotspot for diversity and for finding waterfowl that are not sitting out on open water. For weekend birding, concentrate on Houghton Lake Flats Flooding for swallows and marsh birds, or commit to Backus Creek SGA and Marguerite Gahagan Nature Preserve for a full morning of breeding songbird coverage. The latter two sites are worth covering systematically rather than stopping once or twice; Mourning Warbler in particular rewards patient listening in appropriate scrubby habitat.
Activity in Roscommon County is neither explosive nor minimal right now; it is steady and predictable, with clear hotspots and clear reasons to visit them. The season is turning, and the next four to six weeks will bring shorebirds and transients. Today is a solid day to establish baseline coverage for the beginning of that shift.
