August 3, 2012 Duck River Unit, TNWR. I stopped in, hoping to get photos of the tricolored herons for the ones who doubted my report.I couldn`t find them anywhere, but I had a good time anyway! There were 85 Caspian Terns resting on thier island. 4 smaller terns were with them,I believe were Forsters, but not totally sure because they were so far away. I got a good view of an American Avocet feeding along the shore, and also a flyby Willet. Other shorebirds were Greater and Lesser Yellowlegs, Least, Pectoral, Solitary, and Spotted Sandpipers. There was one lone Snowy Egret, and several Bank Swallows flew by. I saw about a dozen imm. Little Blues and 4 adults but no calico birds. I`ve seen molting ones many times, but none that looked like a Tricolored Heron. Sorry about the lack of photographs, but my 3 birding buddies and I have no doubt about what we saw. Ruben Stoll.
