Gilbert Derouen, Reece Jamerson and Bryan Stevens birded at Austin Springs on Boone Lake, Washington Co., TN, on Tuesday, April 25, around 1 p.m. We enjoyed great looks at a singing male Prothonotary Warbler and later heard a second bird. We also saw three Least Sandpipers and two Solitary Sandpipers. We also had an Osprey, two Eastern Kingbirds and a female Purple Martin. We heard a Great Crested Flycatcher. On the way to Musick's Campground, South Holston Lake, Sullivan Co., TN, we stopped at the pond on left of entrance to Observation Knob Campground. We had one Spotted Sandpiper and one Solitary Sandpiper. At Musick's, 52 Ring-billed Gulls, four Common Loons, two Double-crested Çormorants, a Green Heron and an Eastern Kingbird were the highlights. At TWRA Access Area adjacent to Musick's, we had singing Pine Warbler and White-eyed Vireo. Bryan Stevens, Hampton, TN
