1 brief flyby RED-HEADED WOODPECKER
1 first year BALD EAGLE (soaring)
hatch-year Tree Swallows; Rough-winged Swallows, loads of Indigo 
Buntings, Eastern Bluebird, Green Heron, Great Egret, Great Blue 
Heron, Canada Goose, Northern Parula (along Hunting Quarter Rd), 
Prothonotary Warbler, Acadian Flycatcher, Eastern Wood-Pewee, Great 
Crested Flycatcher, Eastern Kingbird, Common Grackle, Red-winged 
Blackbird, Fish & American Crows, Wood Thrush, American Goldfinch,

Two birders who were there earlier told us they had a LEAST BITTERN 
flush from the marsh, but no such luck for us.

Sycamore Landing
Added a Yellow-billed Cuckoo heard along the towpath
Photographed an Acadian Flycatcher on a NEST, suspended directly 
above Sycamore Landing Road.

Good birding,
Dan
