I am not an expert at identifying birds so I tend to categorize simply. Here are a few friends with white feathers who were at the beach recently for Bird Weekly by Our Eyes Open.
Two views of a sculpture on the waterfront of Seattle, of Ivar Hagland, a local character who was real and larger than life. Ironically the seagulls in this sculpture are larger than life and Ivar is pretty close to life size. Of course gulls feel bigger than they are when coming at you for left-over french fries.
