A Glaucous-winged Gull (my guess!) tugs on something stuck under the water at the Ridgefield NWR, Jan. 21, 2015. As I drove up to the area I noticed the gull out in the shallow lake fluttering around, even using its wings to increase its pulling power on the prize that it had found. This frame with the wings up seemed to portray the situation the best.
