Ultra-rare Gull Visits Stanislaus County

February 23, 2019 By Jim Gain 1 Comment

Few experiences in birding match the thrill of finding a “first” record, which involves not just seeing a bird for its first occurrence in a given place, but documenting (recording) its presence. His impressive skill at photography has enabled Jim Gain to document many of our rarest visitors, including the ultra-rare gull he found a few days ago. More of Jim’s birding adventures and superb photos are at his website, Reflections of the Natural World. ed

In French, it is known as the Gray-mantled Gull, Goéland à manteau ardoisé. In Spanish, it is the Kamchatka Gull, Gaviota de Kamchatka. In English, we call it the Slaty-backed Gull. For those of us living in California’s Central Valley, we call it the “Extremely Rare Gull”. So rare in fact, that it has only ever been seen once before in the entire San Joaquin Valley, and never in Stanislaus County.

SLATY-BACKED GULL WORLDWIDE DISTRIBUTION The Slaty-backed Gull is a regular breeding bird along the coastal areas of the Western Pacific from North Korea, Russia (including the Kamchatka Peninsula) and just a tiny portion of the Seward Peninsula in north Alaska. It spends the winter mostly in the coastal areas of Japan, Korea and the Yellow Sea area of China and can show up unexpectedly in random locations in the US, from California to Texas. As of February 18th of this year, it can now be counted as a visitor to Stanislaus County.

STANISLAUS COUNTY CHECK IN

If it were a FaceBook-using gull, on February 18th of this past week, it could have done a “Check In” from the Recology Grover Environmental Products facility north of the Westley Rest Area.

Or more precisely, it was hanging out with 6,000 of its Facebook friends along the California Aqueduct next to the Recology Facility.

A LITTLE CALIFORNIA HISTORY

According to the records from the California Bird Records Committee data base, the first ever accepted record for the state dates back to February 5, 1995, with the second ever record coming six years later in 2001. Over the past decade there have been a total of 36 accepted sightings. The increase in records could be due to an actual rise in the numbers of birds straying here from Asia, or it could be that birders are more informed and knowledgeable on the identification of the bird. I suspect that it is a combination of both factors.

A FIRST RECORD FOR THE SAN JOAQUIN VALLEY

In February of last year, David Yee (aka birdmanyee) spotted and carefully recorded the first Slaty-backed Gull for the entire San Joaquin Valley, from Bakersfield to the Delta. The bird he recorded was found at the gravel pits along Koster Rd, San Joaquin County, barely a mile north of the Recology Facility on Gaffery Rd, Stanislaus County.

A DREAM BECOME REALITY

In an email communication with Eric Caine on January 29 of this year, I stated, “I’m going to find a Slaty-backed gull in February and I’ll call you when I find it!” Little did I know that less than 3 weeks later, this prediction would turn to fact. I got up early as usual on President’s Day and checked my email, looking for a reason to get out of house cleaning. I soon discovered that birdmanyee had reported another Slaty-backed Gull at the same spot, a year later, as the first record. Knowing that the gulls like to move between the gravel pond on Koster Rd to the canal along the Recology Facility, I jumped in my car and drove, as quickly as legally possible, out to the Recology canal. I have made this trip many times in the past only to find the canal completely empty. As I crossed the bridge over the canal, my adrenaline kicked in as I saw at least 5,000 plus gulls along both sides of the canal. The words came to mind, “Be careful what you wish for!”

SEARCHING FOR A NEEDLE IN A HAYSTACK

So, how hard is it to find and identify correctly, a Slaty-backed Gull? For reference, the same CBRC database of Slaty-backed Gull records over the past decade, also shows that 40% of submitted sightings were not accepted due to the difficulty of identification. There have been 16 different species of gulls documented in Stanislaus County, 8 of which are in the same bird family, Larus. Of these 8 similar shaped and sized species, for adult birds, identification can be narrowed down by a quick look at feet and back color. Adult Larus gulls have a mostly solid mantle ranging from medium gray to dark gray to black. In the photo below the ranges are pretty visible from the medium gray-backed gulls in the middle to the black-backed gull on the upper right corner. In the case of the Slaty-backed Gull in this post, we are looking for one like that black-backed gull.

So as I scanned the flock, I had a search cue set for birds with an obvious black back. The challenge was that the flock moved constantly. Birds came and went, and, on occasion, the entire flock burst upwards in unison, circled around and landed back on the canal bank or in the water, completely mixing up which birds I had already scanned and which ones I hadn’t.

I made one pass though the entire flock, taking about 45 minutes to do so. I turned around and started back. During my first pass, I noted at least 8 to 10 Western Gulls, which have the black(ish) back. They are actually somewhat rare in the county, but can be found here if the gull flock is large enough. I made my way slowly back down the canal, gently causing the birds to mostly just peel off a couple at a time and then fly behind the car and land. Most of them just walked out of the way. I was going very slowly and they practically ignored me.

 So many Gulls

So many Gulls

I was almost completely through the end of the flock again when I noticed a 1st year Glaucous Gull on the other side of the canal. That is another rare species, about as uncommon as the Western Gulls, but not an extreme rarity. I frequently glanced in my side-view mirror to make sure another vehicle wasn’t coming so I could focus on the gull across the canal. I noticed there were two “black-backed” gulls on the berm behind me. I thought to myself, “after I get shots of this Glaucous Gull, I can shoot the two Westerns behind me”.

As a photographer, you can never get too many shots of a rare gull, so after shooting 2 dozen shots of the Glaucous Gull across the canal, I got out of my car slowly, so I could get some shots of the two Western Gulls. I zoomed in and took a shot of the closest Western that was right next to a common Herring Gull, with the other “Western” gull behind them both.

As I focused on the front Western, I took a couple of shots and then decided to try and get all three birds in focus. It was the next focus in my viewfinder that knocked my socks off! The second “Western” gull was clearly NOT a Western Gull, it was THE Slaty-backed Gull.

Suddenly, I couldn’t hold my camera straight, my hands started to shake and my heart beat went off the charts. But I knew that I had to get about a million shots of this bird AND I had to get it in flight. The absolute positive ID of this bird is cemented by the documentation of a series of white pearl spots along the primary flight feathers. The pattern visible on the extended wing shows a terminal white spot, a black spot and a second white spot above the black one. These spots are not present on the similar looking Western Gulls.

Pretty soon, I calmed down because the bird simply could not be bothered by my presence. I slowly started walking towards it, click, click, clicking as I went. Not wanting to scare the poor thing, I just stood there clicking more shots. I even went to video mode and shot about 4 minutes of it just standing there doing nothing. At one point, part of the flock flew up and moved back about 40 feet, but the Slaty-backed just stood there. At this point, the gull was a mere 13 feet away and just watching me.

Suddenly once again, the gull flock took off, and this time the Slaty-backed Gull went with them. I tried to keep up with it amongst the swirling cloud of gulls, but most shots were either blurred or partially blocked by other gulls.

AND NOW, THE REST OF THE STORY

After I had calmed down and was certain I had some decent photos, I reached out to David Yee to see if this gull had the same appearance as the one he had the day before. I sent two snapshots from my camera’s viewfinder via email and he promptly responded that it looked like it might be the same bird. I then texted a few local birders and sent Eric Caine an email with the information. He responded that he was running out the door and would get there as soon as possible. Notifications were then also sent to the local bird groups.

Unfortunately, by the time Eric got out to me at the canal, THE gull was awol.

When I got home, I proceeded to go through the 750 images and 5 videos I had taken and came up with a few shareable images. I then jumped online to social media and I posted on the North American Gulls and the California Rare Bird Facebook Groups. I had over 6,000 hits on my SmugMug site the first couple of days after I had posted them. As of today (2/22/19), while it has been seen at the Koster Rd Pond in San Joaquin County, no one else has seen the gull in Stanislaus County. Queue the music…”I Ran (So Far Away).” The Slaty-backed Gull was number 324 on the Stanislaus County bird list, and one of the rarest ever to make an appearance in our region.

    Mr. Gain,

    With all the junk that happens in this valley, it’s nice to see a feel-good story. But I can’t help but feel for the bird — poor thing got lost and wandered into a man-made ditch in one of the least desirable parts of the US. I wish this bird the best.

    Let’s keep this under wraps, though. If Trump gets wind, he’ll start pushing for a bird wall. Nice work and cool pictures. Thanks,

    JT
