I live in Shreveport, LA.  There are various bodies of water nearby, many of them offshoots of the Red River from its direction changing over the years.  I found this bird feather in a parking lot.  It is approximately 7 inches long.  With unusual coloration, I believed it would be easy to photo ID online.  But that is not so, at least not for me!  Since it is fairly large, I had in my mind the idea that it belongs to some type of waterfowl.  From looking at pictures of green herons, I believe it might be from one of those.  Yet I can find no individual feather photos to confirm that.  I usually find success using the Feather Atlas, but the only feathers I can find there for a green heron are all one color and there are only 3 in total listed. If anyone can provide insight and direction as to a correct ID I would truly appreciate it.
