Tim, my dad, and I birded Deer Run Forest Preserve from around 6 am to 11 am and found nearly 70 species of birds. We found several Bobolinks, a first summer male Orchard Oriole and Henslow’s Sparrow before getting back into the woods.

Other notable birds were high numbers of cuckoos. ~8 Yellow-billed and 2 Black-billed. In the big field south of the railroad tracks we found another Henslow’s Sparrow and a Northern Harrier. We had 2 Olive-sided Flycatchers and a Prothonotary Warbler that gave us pleasant views as he sang his golden heart out.

There were lots of Lark Sparrows and at least one singing Vesper Sparrow.

No Dickcissels or Sedge Wrens yet. Since December 1st we’ve found 136 species at Deer Run.
