Subject: [pen-bird] Photos of Slaty-backed Gull
Hello all,

I got a message that Aaron Maizlish found the bird a few minutes ago. So
it is still there.

Here are some photos:

https://ebird.org/checklist/S63397461

Visible from the Venice Beach parking lot overlook of the mouth of
Frenchman's Creek. There is a big pond at the creek mouth all the way up
Pilarcitos Creek, so few people were on the beach as some of the access
points are not available. So hopefully it will not get spooked.

It is like a Western Gull, an adult, with pink legs and a dark back.
However the back is darker. It has pale eyes with some brown flecks and some
crisp streaking on the head, unlike Western. The legs are brighter almost
bubblegum pink. The outer primary has an entirely white tip, not just a
white mirror. Also there is a mirror on p9, the next primary in from the
outermost. On Western, there is one mirror on the outer one and it does not
reach to the tip. Inside of this there are white tongue tips, or half moon
shaped bits on primaries where the black meets the slaty gray. They form a
series of pale "spots" that creep out along the open wing creating what has
been termed the "string of pearls." It has been a while since a classic,
adult Slaty-backed Gull has been out on the beach. So it was a nice one to
see!
