Chris Izworski's daily Michigan birding report focuses on Saginaw County this morning, where the past two weeks have been dominated entirely by activity at Shiawassee National Wildlife Refuge. The Wildlife Drive there continues to be the only location generating substantial observation effort, with 142 species reported across 142 observations in the last 14 days. What's being seen right now tells a clear story: mid-July means waterfowl and marsh birds congregating in good numbers, with some notable wanderers showing up.
Waterfowl and Rails Holding Strong at Shiawassee
Mallards lead the count at 48 individuals, followed closely by 38 Wood Ducks, all reported yesterday from the Wildlife Drive. American Coots are staging in good numbers at 33 birds. Double-crested Cormorants have pushed to 18, and Sandhill Cranes are matching that count. The marsh birds are equally active: 15 Common Gallinules, 12 Marsh Wrens, and sustained reports of Green Herons at 7 individuals. These numbers are exactly what you expect in late July when breeding activity is winding down and pre-migratory staging begins in earnest. The shallow impoundments and reed beds at Shiawassee are doing their job.
Caspian Terns have appeared at 12 birds, with Common Terns also present at 8. Both species favor large open water or nearby fishing habitat. The tern activity suggests the refuge's larger pools are holding well and attracting feeding flocks.
Little Blue Herons and Western Cattle-Egrets: The News
The most noteworthy observation is the repeated appearance of Little Blue Herons at Shiawassee NWR's Wildlife Drive, with multiple reports flagged as notable including 2 birds on July 19. Western Cattle-Egrets have also been reported multiple times at the same location over the past two weeks. Both of these are well outside their typical range for Saginaw County and represent legitimate rarities. The Little Blue Herons could be post-breeding wanderers moving north; Cattle-Egrets appearing in Michigan in mid-summer are increasingly documented but still warrant attention. If you're heading to the refuge today, these two species should be on your shortlist. A Pine Siskin was also reported in Saginaw proper on July 19, an unusual record for summer in the lower peninsula.
Tern Activity and Song Sparrows in the Marshes
Song Sparrows are well distributed at 14 individuals, a healthy number for the marsh habitat that Shiawassee protects. Eastern Kingbirds tally 8 birds, working the shrubby margins. Common Yellowthroats are present at 8 as well, though July is when they become quieter and harder to locate. Rock Pigeons round out the top counts at 22, typical for any refuge with building infrastructure.
Weather and What to Expect Today
Conditions this morning favor early birding before the heat builds. Sunrise is at 6:13 AM with a dawn chorus window extending to 7:43 AM. The SSW wind at 6 to 15 mph is mild and shouldn't disrupt activity. Patchy smoke is noted in the forecast, likely from western fires; visibility may be compromised depending on time of day. More importantly, tonight brings showers and thunderstorms with tomorrow bringing a 20 percent wind from the west. By midweek, conditions may push some additional waterfowl into the refuge system, though late July is primarily a staging period rather than a migration peak in this region.
Where to Bird Saginaw County Right Now
Shiawassee NWR's Wildlife Drive is clearly where the activity is concentrated. The refuge's 276 all-time species at that location and the consistent recent reports make it the obvious choice. If you have time for a second location, Ferguson Bayou Trail within the refuge system offers 259 all-time species in a different habitat structure and might turn up something different from the drive. The north section of Shiawassee River SGA is also available with 199 species recorded but appears to be receiving less observer effort currently.
Observation effort in Saginaw County remains narrow, focused almost entirely on Shiawassee. Other locations like Crow Island SGA's West Units and the Woodland Trail are not generating current reports despite historical records. If you visit those areas and find activity, those sightings would expand the county's coverage picture.
