A male King Eider is currently on the backshore. Two gentlemen from Carlisle were kind enough to allow me to look through their scope and Michelle Barton reports that it was there on Friday, too. The eider can be seen while standing at the small cleared space on the side of the road, across from The Elks at Bass Rocks. The King Eider is a spectacularly colored bird and is too far offshore for the capabilities of my 200mm lens but here is a beautiful photo from Wiki Commons Media. King Eiders forage on seabeds up to 82 feet deep and I imagine that is what the diving eider spotted this morning was doing. Happy Birding!
