|April 2017 concluded with a new Big Day record for Monterey County: 217 species.
On 28 Apr 2017, the team of Blake Matheson, Paul Fenwick, Cooper
Scollan, and Brian Sullivan (L to R, photo © B.T. Matheson)
shattered the prior record of 208 species, set back on 1 May 1999. This
was the first 'serious' Big Day in MTY in the 21st century under formal
ABA rules [>95% of species must be identified by all; this team had
97%. They also used no playbacks]. Extensive scouting before the Day
helped locate most breeding species as well as 5 species of lingering
geese; strong winds at the coast helped sea-watching (lots of
Black-footed Albatross); and a string of rarities around Moss Landing
added the frosting: Redhead, White-faced Ibis, Red Knot, Franklin's
Gull and even better — and fully consistent with the "Year of the Gull"
— were two extraordinary gulls at the Pajaro R. mouth: a first-cycle Lesser Black-backed Gull (the 3rd for 2017!) and a first-summer Little Gull flying over (below left © Paul Fenwick). And then — even more remarkable — an adult Little Stint was
at Jetty Road, Moss Landing (below right © B.L. Sullivan;
left-hand wader with Western Sandpipers & Semipalmated Plover).
This is the first spring record for Monterey (3rd MTY record overall)
and a major rarity anywhere in North America. The i.d. of this rare
wader did not get sorted out until a day later, and efforts to relocate
read below that three rare passerines at Laguna Grande lingered into
March. As it turned out, one of them remained until the third week of
April. This Yellow-breasted Chat (left, photo 19 Apr
© D. Roberson) was initially discovered 20 Nov 2016 and lingered
through at least 21 April, a full 5 months later. On its last date it
was singing a 'whisper song' in its favorite patch of willows at Laguna
Grande. The fact that it was singing, and had developed a black bill
and black lores over the winter, means that it was a first-winter male.
The speculation (below) that it might be a female because of pink bill
and brown lores turned out to be wrong. The bird did replace its tail
over the winter, and the loss of that tail might have been the reason
it stopped migration and stayed here. Again, that's speculation.
THE YEAR OF THE GULL
first four months of 2017 may long hereafter be known as the "Year of
the Gull." It started in January, with the California Central Coast "Trifecta" — a Slaty-backed and Black-tailed Gull here in MTY — and an adult Ross's Gull in San Mateo County. Alternatively, local MTY birders were also treated to a gull "Trifecta" — with a Lesser Black-backed substituting for Ross's. All are featured farther down this page.
March brought further madness (see just below) but in early April a first-winter Laughing Gull
at Pt. Pinos, found by Blake Matheson on 4 April, added yet another
vagrant to the pile. It was in active wing, tail, and body molt (photos
right, upper © BT Matheson, lower © D. Roberson). Laughing
Gull is occurring with more frequency; this was at least the 17th MTY
record, but just the 4th for the Monterey Peninsula, all at Pt. Pinos.
The prior birds were on 21 May 1966, 27 June 1975, and 1 May 1999 --
but this is the first to be documented with photos.
As it turned out, the first-cycle Lesser Black-backed Gull
at Marina (see details and photos from January, below) was an even
rarer bird than initially thought. It was rediscovered in March by
Brian Sullivan. In reviewing his photos, expert opinion from the Old
World was that it is assignable to the taxa taimyrensis, breeding in northeast Asia and wintering in southeast Asia. This population is currently assigned to Larus fuscus [Lesser Black-backed] but some authorities split fuscus into several species. Under that approach, taimyrensis is a race of "Heuglin's Gull" Larus heuglini. The MTY bird, if accepted as taimyrensis,
would represent a first for the New World under a new taxonomy. In
Sullivan's photo below (17 Mar © B.L. Sullivan), the vagrant is on
the left. It has new first-cycle back feathers but has retained juvenal
lower scaps, upperwing coverts, and tertials. This state of plumage in
late winter supports the i.d. as taimyrensis.
|Also in March, Blake Matheson found another Slaty-backed Gull,
this one near Marina on 17 March (above left © B.T. Matheson). At
the same location on 17 March was the same first-cycle Iceland Gull
that Brian Sullivan had previously photographed at the Carmel River
lagoon back on 22 January (see below; a March photo is above right,
© B.L. Sullivan). This individual had a unique smear of tar across
two secondary feathers on its right wing, as shown in this shot. When
one considers the amazing Black-tailed Gull, a taimyrensis Lesser Black-backed, two Slaty-backs, at least two Iceland Gulls, plus a vegae Herring Gull and an apparent kamtschatschensis
Mew Gull, with a Laughing Gull as a late throw-in, well, never have so
many high-quality vagrant gulls been seen within such a short span of
time and place. And equally remarkable — every one was documented with
was also the month in which our three amazing passerines at Laguna
Grande finally departed, each having successfully wintered locally. The
first to depart was the Lucy's Warbler, whose last known date was 4 March when it was photographed by Bill Hill (left, upper photo © Bill Hill).
The Black-throated Green Warbler
was last seen on 22 March, and also photographed that date (left, lower
photo © D. Roberson). By then it was showing more black on the
throat than had been there when it was discovered in December.
The lingering Yellow-breasted Chat
— which you'll recall was an adult female that had lost its tail in
late fall but grew in another over the winter — was last observed on 27
March (Virginia Chomat), still frequenting the same dense willow
thicket at which it had spent most of the winter.
Other passerines that completed a wintering stay included a male Orchard Oriole in Moss Landing, returning for a second winter (David & Jane Styer) and a male Summer Tanager
in Pacific Grove that spent its 4th winter here (D. Roberson, R.
Carratello, B.T. Matheson). Somewhat less rare, but always nice, were
single Yellow, Palm, and Black-and-white Warblers at Laguna Grande, and
another Black-and-white at San Carlos cemetery in Monterey. A scarcer
bird — a male Williamson's Sapsucker found on private
property in Corral de Tierra on 9 Feb (Patricia Farr) — did not survive
the winter. It hit a window and is now a specimen at Calif. Academy of
A Solitary Sandpiper
found by Paul Fenwick on 15 January represented only the second winter
record for MTY. This year's individual (photo right © P. Fenwick)
was on a small rain-filled wetland near the west end of the now-closed
Rancho Canada golf course, adjacent to the Carmel River in lower Carmel
Valley. It is the first to be documented in a MTY winter by photos.
The prior winter record was a long time ago: 27 Jan 1994 near the Pajaro River mouth (Michael Perrone).
were the focus of most everyone's attention in January 2017. The story
begins with "a man and his gull" (below © BL Sullivan). That's
Blake Matheson pointing to the only gull on the beach at the very tip
of Pt. Pinos. It is a Slaty-backed Gull.
discovered this mega-rarity — just the 3rd ever in MTY and super rare
anywhere in California — on 9 January, and took photos, including this
flight shot (below © B.T. Matheson). Notoriously difficult to
identify, the fact that this second-cycle Slaty-backed Gull was molting in dark gray back feathers, and had a bright yellow eye, aided identification.
Blake saw the Slaty-backed on 9 Jan, but it was on the beach at the tip
of Pt. Pinos again the next morning; many locals got photos. It was
seen off-and-on through at least 12 Jan. On 12 January, the Ross's Gull
in San Mateo County was the headline news (see Sidebar to right) but by
mid-day on 13 January, word got out that a first-cycle Black-tailed Gull (below © D. Roberson) was at Pt. Pinos!
While multitudes were still combing Pt. Pinos for the Slaty-backed Gull, word came at 2 p.m. on 12 January that an adult Ross's Gull was at Princeton harbor in San Mateo Co.,
two hours hard drive to the north. At least 4 MTY locals made it there
before dark that day, and others reveled to the unworldly loveliness of
this Siberian breeder the following two days. This was only the second
California record. Given its preference for the edge of Arctic
pack-ice, its presence in central California made it one the most
spectacular rarities ever to reach this State [these photos, below,
from 12 Jan © D. Roberson].
The odyssey of this Arctic gull had a poignant ending at 2 p.m. on 14 January. Tom Stienstra, wildlife writer for the San Francisco Chronicle, described it this way in the Sunday paper for 22 Jan: "After
hundreds of people sighted and photographed the bird at the harbor, it
flew north a mile to a field of Brussels sprouts opposite Half Moon Bay
Airport . . . What followed shocked many who aren't always exposed to
the full spectrum of nature: A pair of peregrine falcons, the fastest
bird in the world and a fierce predator, teamed up and bushwhacked the
rare gull. After a flight of 9,000 miles, one of the rarest wildlife
sightings in California history ended up as lunch."
Sometimes we underestimate the perils faced by the
vagrant birds we so enjoy. Many continue on 'wrong-way' flights across
the Pacific and are lost at sea. Others, like this incredible lovely
Ross's Gull, face new and unexpected predators. R I P
combination of these three unexpected gulls from northeastern Asia
within the span of just five days — and two of them in MTY — is
unprecedented. The Ross's was a second State record. The Black-tailed was the first ever for MTY, and just the 4th for California. Slaty-backed
averages less than 4/year in all of California, and almost none have
been 'chaseable' for nearly a week. For those chasing and seeing all
three of these gulls, the accomplishment became known as The Trifecta.
A bit more about the two MTY gulls below. . .
|The Slaty-backed Gull
(above and left, © D. Roberson) behaved quite differently that the
other large gulls packed together at the tip of Pt. Pinos at high tide.
It strode off alone, away from the other gulls. It hunkered down by
itself just over the lip of the parking lot. On the day it was
rediscovered — just after a rainy night — it walked into the middle of
the parking lot and drank from rain puddles. It then strolled down
Oceanview Drive until flushed by a jogger, flew a short distance to the
next parking lot south, and went to sleep on a large comfortable rock.
Like the Ross's at Half Moon Bay, it seemed oblivious to people and
cars, sometimes walking right up to them.
|As to the Black-tailed Gull
at Pt. Pinos, the initial question by many local observers was "Who
found it?" It was a first-cycle gull of a species not known to most
American birders (its primary range is Japan and Korea). We got word by
text from local birder Bill Hill at noon on Friday, 13 January.
As it turned out, the Black-tailed Gull was
discovered on the rocks across from Crespi Pond in late afternoon of
Thursday, 12 Jan by Mark and Lucas Stephenson, father and son from
Napa. They did not know what it was but took this photo (right ©
Mark Stephenson). The next morning an unfamiliar gull was spotted
bathing in Crespi by Steve Turley, from Long Beach, birding with Becky
Turley and Nancy Strang. The gull flew across the road to the beach,
where Steve pointed it out to Tom Wurster, with Andrew and Vernon Howe,
also from southern California. All of them were present in search of
the Slaty-backed Gull (which was not found). Bill Hill arrived and
together they came up with a probable Black-tailed Gull. Bill got the
word out at noon— with a photo (one of Bill's photos is below, ©
Bill Hill) — and the stampede was on. Alas, at 2 p.m. the gull flew off
northwest into Monterey Bay; many arrived too late.
In the early afternoon of Sunday, 15 Jan, Breck Tyler rediscovered the first-cycle Black-tailed Gull
at the Carmel River mouth lagoon (photo left, with a California Gull,
© W.B. Tyler). Two days later, near dusk on 17 Jan, a number of
local birders watched it fly in from the sea to check out the Carmel
lagoon, and fly out to sea again. It was then seen at Crespi and nearby
on 18 Jan, but it has not been convincingly reported since then,
despite the efforts of many to relocate it.
Since then more interesting gulls have occurred, some of them controversial, and all initially discovered by Brian Sullivan:
- An apparent first-cycle "Kumlien's" Iceland Gull
at the Carmel River lagoon on 22 Jan (photo right © B.L.
Sullivan). Bill color shows this is a different bird than the Marina
- Another apparent first-cycle "Kumlien's" Iceland Gull at the Marina landfill, first photographed by Sullivan on 14 Dec 2016 (see prior update) seen several times since, and photographed on 21 Jan (below left © Blake T. Matheson); and
- A gull showing characters "Kamchatka" Common Gull, a NE Asian population currently lumped by AOU with Mew Gull [L. canus kamtschatschensis] but split by other authorities, at Pt. Pinos on 21 Jan (below right, photo © D. Roberson).
to the latter, the "Kamchatka" Gull looked structurally like a
Ring-billed Gull, being larger, longer-legged, and longer-and-thicker
billed than Mew Gulls nearby. Tail pattern (mostly dark) was a concern
but this pattern was similar to 40% of the Kamchatka tails studied by
Adriaens & Gibbons (2016). In the photo here, it had just caught a
small fish in the high surf.
And then — just when we thought no more rare gulls could possibly be found — Brian Sullivan struck again with a first-cycle Lesser Black-backed Gull
at the Marina landfill on 25 Jan (photos right and below © B.L.
Sullivan). The white rump and tail, with its broad blackish subterminal
band, is distinctive. Note also the many crisply-edged juvenal feathers
on the lower back, scaps, and coverts, producing an appearance in
first-winter gulls unlike anything shown among other usual assortment
of Larus gulls and their hybrids. This is the 3d MTY record and a rarity anywhere in the State.
first two record for MTY were adults, and both were a long time ago: 14
Jan 1978 Roberts Lake (L.C. Binford, B.D. Parmeter, Ron Branson) and 11
Jan 2003 on a sandbar in Elkhorn Slough (Todd Easterla, Steve Rovell).
Word of these birds did not get out quickly, so neither proved
chaseable. The 1978 gull was the first record for California, and
Laurie Binford published a classic paper on its occurrence and
identification (Binford 1978).
|In decades past, all claims of Swainson's Hawk
in winter were considered bogus the moment they were mentioned. Many
birders have problems identifying raptors. But in recent years a few
absolutely legitimate Swainson's Hawks have been found in winter here
in MTY. This year it was this light-morph bird (photo right © Paul
Fenwick) seen over Laguna Grande Park on 6 Jan by Fenwick, Jim
Mitchell, Steve Rovell, and Rick Fournier. Later in the day it was seen
again over Hwy 68, heading towards Salinas, and then either this bird,
or another like it was north of Salinas over Hwy 101 on 14 Jan (Karen
birding year begins on 1 January, as always, with the Moss Landing CBC.
This year's count was very good, with 199 species (pending review of
rarities). Among the best from the MTY part of the count circle was a
Bank Swallow on the private-owned Packard Ranch, north side of Elkhorn
Slough, found by Peter Metropolus and well-described by Mark Kudrav in
eBird. This is now the 3rd MTY record in winter (all in early to mid
January) but the best documented one yet (none of them was
photographed). Last year's male Orchard Oriole also returned to Moss
Landing town over the New Year (David Styer).
What was nicely photographed was this vagrant Royal Tern,
foraging inshore from Otter Pt. to Pt. Pinos on 4 Jan, found by Brian
Sullivan (photo left © Cooper Scollan from Otter Pt.).
Perhaps even more amazing was that the rare landbirds at Laguna Grande Park, all photographed on the Mty Pen CBC (see last update),
that were still present into January: Yellow-breasted Chat, Lucy's
Warbler, Black-and-white Warbler, and Black-throated Green Warbler. All
were seen into late January when this report was updated.

first found at Carr Lake, Salinas, on 10 Dec (Mike Stake) — apparently
lingered only to 5 Jan 2017 (right, photo © Kent Van Vuren)
