Hello all,
Late this afternoon I made a quick stop at Haines Wharf Park in North
Edmonds to do a short quick scan of the area. Heat shimmer and rough water
made distant birds unidentifiable, so I turned my attention to the gulls
that roost on the old wharf building there. Pretty quickly I noticed a very
dark mantled gull. After eliminating a very dark Western as a possibility
due to extensive head streaking I spent some time taking photos and video
of the bird. My hunch in the field was either Slaty-Backed or possibly
Lesser Black-Backed, but the pale pink leg color among other field marks
seem more consistent with Slaty-Backed.

Birders later in the evening were unable to relocate the bird, but it could
conceivably turn up at any of the gull roosts on south Whidbey Island or
the Kitsap Peninsula as well as Edmonds.

A couple photos are on my Flickr page:
