Since the first of Dec., 2020, we've notice a different type of bird around the pond in my parents' backyard in Georgia. We live in the middle of Georgia, about 80 miles south of Atlanta. It perches on the water drain and spreads its wings after swimming. There were two birds at first, but over the last few days, we've only seen the one. It is fairly large, similar in size to a great blue heron and smaller than a Canadian goose. It appears to have black webbed feet like a Canadian goose, with a yellow beak, tan neck and chest, with dark feathers on its back. Our best guess has been a juvenile or female anhinga. Can anyone identify this bird for us? Thank you!
