Lake Merritt was the first wildlife refuge in North America and is on the migratory path of many bird species. Egrets and herons tend to hang around the bay's shoreline. This one was intent on grabbing something that caught his eye and made several passes at it, but came up with empty talons. I'm linking to Weekend Reflections even though this is more of a shadow than anything else. Hope it's allowed. BTW, this is a color photo, not a b&w.
