I had never heard of, or seen, this bird before and had to look it up. It's really a large bird.
My bird book says that the Anhinga is about 35" with close to a four foot wingspan.
The males and females look a lot alike, but if I'm reading my book correctly this is a female. The buff brown neck and breast are on the females. The one I shared last week was the male, black head and neck.
