January 4 - Gull Darn It!


At 11 a.m. I drove downtown to scope the mudflats at the Port of Olympia's North Point, and arrived in the midst of a Puget Sound 45° rain,

which the birds were trying to snooze their way through.

or, this miserable Double-crested Cormorant
I did see a Western Grebe near the Hearthfire Restaurant,

which was my first for the year as was this White-crowned Sparrow on my way back to the car.

Then I drove over to Mud Bay to scope the gulls, looking for an immature Glaucous Gull that had been seen there this week, but no luck.  I continued down to the Department of Natural Resources Preserve at the mouth of Kennedy Creek,

but it was high tide and little to be seen,

although there was a single Black-bellied Plover on the grassy island, which was new for me for the year.
I returned to Perry Creek to scope through the gull congregation there.  Although I couldn’t find the Glaucous Gull among the 600 or so gulls roosting there and scavenging on old chum salmon carcasses,

I did find a single immature Thayer’s Iceland Gull in the flock (sorry, no photo).  The mergansers were feeding in amongst the gulls.

I finished the day with another stop at Mud Bay and called it a day with 3 new species for the year, bringing my species count to 86.  I didn't find the Glaucous Gull, but it wasn't a bad day at all.

December 14 - Perry Creek Gulls and Chum Salmon


I drove over to the mouth of Perry Creek to see what gulls might be congregated for the chum salmon run.  As I arrived, 3 immature bald eagles were just leaving, and the gulls were settling back down for their lunches.

Perry Creek, along with McLane, Perkins, and Swift Creeks, furnishes the bulk of the fall chum that return to Eld Inlet.  The four creeks together have averaged an annual ‘escapement’ of about 45,000 adults over the past 5 years.  The bounty of fish eggs and fish carcasses is a big draw - and a huge source of protein - for gulls, eagles and ducks.
Feeding on a chum carcass - Yum!
The peak of the run into Perry Creek appears to be past, but there are still fish entering from Puget Sound, although none are “bright”.  Now, even the freshest fish are what the commercial fishermen refer to as “alligators”: pretty colored-up as they enter fresh water

I scanned the large flock of over 400 gulls and saw an immature gull with a bi-colored bill.  Oh, joy! I thought; it may be an immature Glaucous Gull, which is an uncommon visitor from the northlands.

But, the bird turned to show its side, and revealed itself to likely be ‘just’ a Glaucous-winged Gull.  Steve Howell’s book Gulls of the Americas notes that “… some (pure?) birds … have strongly bicolored bills, recalling Glaucous Gull."

There were mostly Glaucous-winged gulls in the flock, although there are always some hybrid Glaucous-winged X Western Gulls, told by their darker wingtips and mantles, combined with dusky head feathering.  These hybrid gulls are common enough here in south Puget Sound - especially during the salmon runs

The Western X Glaucous-winged Gull hybrid is often referred to, among local birders, as the "Olympic Gull"
I believe that there were a number of Glaucous-winged X Herring Gull hybrids in the flock, as well, because several had very pale eyes - more so than the other Glaucous-winged birds.  I do note that Howell (op. cit.) tells us that up to 5% of the Glaucous-winged Gulls can have pale eyes.  However, the only birds I saw with the really pale eyes also had dark wing-tips.

Please let me know if I've mistaken my ID:  I’m always up for being schooled on gull identification skills!

While I was watching, all the gulls crouched and looked up, and sure enough, an adult Bald Eagle came dropping into the flock.

The gulls barely got out of the eagle’s way as it fed on a chum carcass.

This is a great place to sort through the gulls during and after the salmon run.  There will be dead spawn-outs at the mouth of the creek into next month, attracting the gulls and immature eagles.
