From Dan & Trudy Rottino: 4/18/13-- Madison, Hammonasset SP-- 1 AMERICAN BITTERN. Also 4 PURPLE MARTINS. A very strange sighting was a Turkey Vulture lying down in the marsh at very close range by Willard's Island. I figure it was sick or incubating??? Usually a vulture would flush at that close range. They've gotta be somewhere. Dan Rottino Sent from my iPhone.
