Chattahoochee River 7/15/12

A few days ago, my father, sister and I went to the Cochran Shoals Unit of the Chattahoochee River. We walked the usual route, but did not see as many individual birds as usual. There were a few highlights, though, including a Yellow-crowned Night-Heron across the river, a Common Yellowthroat that flew from one bush to another and sang its “wee-wichity-wichity-wichity” song and a Red-headed Woodpecker that flew across the path, a first for Atlanta for me. The Yellow-crowned Night-Heron could have been and probably was the same one I saw just off the swamp boardwalk last time I visited. I have never seen or heard a Common Yellowthroat at that location so that was a cool first! There was a juvenile male Northern Cardinal at the top of a tree and I got to see some of the swallow nests under the lip of the bridge-portion of I-285 as cars passed over above. The species count was also low, but it was later in the evening and so perhaps there were not as many birds around. There were quite a few trees and one perched dragonfly that I identified as a Blue Dasher. Here are the species of animals and plants seen:
