We just saw the Swallowtail Gull at 24233 Richmond Beach Dr NW, Edmonds US-WA (47.7799,-122.3934)
The bird is on the pier just below the metal building. It's almost impossible to see from the road you may have to walk along the beach and get to the pier. We've been told the property is closed to the public. There are two rows of birds and the Gull is in the lower row. Look toward the north end of the building by the green shed.
