A seagull that was sitting higher up on the rock jumps over a seagull into the water below much to the dismay of the lower seagull.
A Sanderling (Calidris alba) lost its footing and slid down the rock.
I spent about a half an hour watching two Great Egrets (Ardea herodias) fishing. Neither egret was having much luck. I thought the Egret's expression in this photo told the story.
