This evening in Shady Valley at Orchard bog I spotted a large white bird interacting with a Blue Heron. Both would emerge from the tall grass and then retreat back to cover. I witnessed this behavior several times from 8:15 PM until dark around 9:00pm. There was a great distance between the birds and I and they appeared to be closer to the Orchard Bog road than my location at the Nature Conservancy site. I relocated to the Bog road and one more display was observed, however just as far away. If I were to hazard a guess I would say an great egret although I really do not know. It was comparable in size to the Blue Heron. Anyone else spotted this one? Don Carrier Bristol, Tennessee www.birdsgonewild.org
