Fog over the wildflowers in the retention pond near the parking area at Bles Park. It is full of blooming goldenrod, Common Boneset, Blue Mistflower, Bidens and more. Sadly, this is one of the areas that will become a parking lot.

As we ventured into an open area, we picked up more warblers along with our missing mimic: the Brown Thrasher.  Two Brown Thrashers posed helpfully at the top of a nearby tree.  The marsh was quiet with only a Green Heron visible.  Down the path, we happened upon another Magnolia Warbler that was hanging out with a Common Yellowthroat and a Blue-winged Warbler.   Around the bend, we found a Least Flycatcher.  Along the Potomac Heritage Trail, we found another flock that seemed to move with us for a good portion of the walk.  The flock was high in the trees, but provided glimpses of Black-and-white Warbler, Chestnut-sided Warbler, American Redstart and Canada Warbler.  Several Swainson’s Thrushes filled out our list of migrants in the mature forest section of the park.  In the parking lot when we were about to leave, we spotted a migrating Broad-winged Hawk high overhead.  What a blissful day!  All told, we found 48 species of birds.  The full list of species (including eight species of warblers) can be viewed on eBird:  https://ebird.org/checklist/S118900041).
