Heron?

Just before sundown I saw a huge shadow on the window blind that faces west.  Jumping up and looking out one of the windows that faces the arroyo I saw what I thought was a Sandhill Crane sitting at the top of our neighbor's tree.  The more I look at this silhouette image, though, the more it looks like a heron to me.  If it is a Blue Heron it probably came from Mesilla Valley Bosque State Park.
