I birded at lunchtime at Blackhawk Springs Forest Preserve and found an Olive-sided Flycatcher high atop a large tree along the bike path past the 1st bridge on the Mulford Road side. Other interesting birds - many White-breasted Nuthatches and American Robins… still seeing lots of Indigo Buntings and there was also a Tufted Titmouse mixed in.

I haven’t found any warbler activity yet but it is usually quite hot and humid in my 45 minute or so lunchtime hikes.
