Report for September 21, 2017                                                                                                                 Birding at Marymoor

Arguably the best day birding at Marymoor ever. No, really. The place was just dripping with birds. The weather cooperated by hardly dripping at all. Week 38 is often a pretty special week during fall migration, but it really outdid itself this time.

Highlights:

  • Cackling Goose – two or three flocks – First of Fall (FOF)
  • Western Grebe – one on lake
  • Virginia Rail – one heard spontaneously calling near Lake Platform
  • DOWITCHERSfour, presumed LONG-BILLED, in flight with ~8 other shorebirds (Pectorals?)
  • Glaucous-winged Gull – long overdue FOF
  • Double-crested Cormorant – at least 2; FOF
  • TURKEY VULTURE – a tight kettle of TWENTY-ONE, moving south
  • Northern Harrier – probably at least 6 birds; all the ones seen well juveniles
  • Sharp-shinned Hawk – one – FOF
  • Barn Owl – one at south end of East Meadow, 6:32 am. First in 5 weeks
  • Hairy Woodpecker – one across the slough
  • Pileated Woodpecker – one seen distantly in flight
  • AMERICAN KESTREL – beautiful adult male – First for 2017
  • Merlin – chased Kestrel, as well as many other birds
  • Western Wood-Pewee – 2
  • Willow Flycatcher – 1
  • Warbling Vireo – 1 at Rowing Club
  • Violet-green Swallow – everywhere; probably 120+
  • Barn Swallow – at least 10
  • Ruby-crowned Kinglet – perhaps 4; FOF
  • Varied Thrush – perhaps 4; FOF
  • LAPLAND LONGSPUR – at least 3, East Meadow & Dog Meadow
  • Orange-crowned warbler – in the ballpark of 40 birds!
  • Common Yellowthroat – numbers down, but still a dozen or so
  • Yellow Warbler – perhaps 10
  • Yellow-rumped Warbler – drab Audubon’s type – about 15
  • Black-throated Gray Warbler – ~4
  • Townsends’s Warbler – 1 or 2 at Rowing Club
  • Savannah Sparrow – maybe 50
  • CHIPPING SPARROW – 1 at Pea Patch
  • Fox Sparrow – ~25, many singing; FOF
  • Lincoln's Sparrow – at least 20, with one singing
  • Western Tanager – at least 4; FOF
  • Western Meadowlark – at least 2

I’m pretty certain we set high counts for Dowitcher, Turkey Vulture, Northern Harrier, Orange-crowned Warbler, Savannah Sparrow, Fox Sparrow, and Lincoln’s Sparrow.

Our total for the day, at 78 species, is almost certainly a high count for fall, and very close to our all-time high species count over the last 23 years!

I didn’t want to leave; I’m pretty sure with more time we could have topped 80 species. But I had to race home to head north for the WOS Conference in Blaine.

Report for September 17, 2016                                                                                             Birding at Marymoor

This is the end of Week 38, which is notable for being the week in the fall where summer and winter birds overlap the most, with a pretty wide variety of migrants thrown in as well. We’ve cumulatively recorded 127 species for Week 38, which is ten species more than any other Fall week. Today was probably pretty typical of a Week 38 outing. We fought through morning fog, which greatly limited our viewing for the first hour (as well as pre-dawn), and were rewarded later with a beautiful, sunny morning.

Highlights:

Western Grebe                    One on lake late; First of Fall
Green Heron                        Adult and subadult at Rowing Club
Turkey Vulture                     1 from Rowing Club, looking east of slough – FOF
Osprey                                Still one seen
Northern Harrier                  Juvenile in East Meadow
Cooper’s Hawk                   Several sightings
Band-tailed Pigeon               A few flybys
Vaux’s Swift                        Notably many ~15
Red-breasted Sapsucker      Many sightings
Willow Flycatcher                One near Compost Piles – 2nd latest ever
Violet-green Swallow           25+
Barn Swallow                       50-100
Bushtit                                  Single flock of 30+
Pacific Wren                        One near start of boardwalk
American Pipit                      Several unseen flyovers
Cedar Waxwing                   Single flock of a dozen
Common Yellowthroat         Only a very few
Yellow Warbler?                  One yellowish warbler
Bl.-throated Gray Warbler    Two together along slough
Western Meadowlark           One, East Meadow, FOF

For the day, 62 species.

Report for September 17, 2015                                                                                             Birding at Marymoor

This was one of those times when I have trouble sleeping because it rains all night, and I wake up worrying about being prepared for the deluge in the morning, only to have the rain stop well before dawn and not start up again until late morning. Matt got a little wet with his ridiculously early arrival, and we had a bit of light rain at the Rowing Club, but otherwise we lucked out. It was even moderately birdy to boot, with some nice surprises. Definitely getting to be fall, though.

Highlights:

Green-winged Teal                      Small flyby flock – First of Fall
Double-crested Cormorant          2 at lake – First of Fall
Osprey                                        Still one around, according to Ollie
American Coot                            Small flock on lake
COMMON TERN                      Two well south on lake
Barn Owl                                     Matt had 1, 6:00-6:10 a.m. I got there at 6:15
Red-breasted Sapsucker              At least 2
Pileated Woodpecker                  1 glimpsed twice, heard often
Merlin                                          Landed near east end of boardwalk
Hammond’s Flycatcher                Ollie had one in Pea Patch
HUTTON’S VIREO                   Rowing Club parking lot
- swallow sp. -                            About 3 seen well to the east
Swainson’s Thrush                      Matt heard a few pre-dawn
Varied Thrush                             1 calling, Big Cottonwood Forest – First of Fall
American Pipit                             Flyovers
Orange-crowned Warbler            Three in/near the Pea Patch
Yellow-rumped Warbler              Several in slough below weir – First of Fall
Fox Sparrow                               2-3, one singing – First of Fall

We saw the two COMMON TERNS from the Lake Platform at extreme distance. They looked very small and tern-like, but never plunged into the water. Because they were surface-foraging without diving, we thought they might be Bonaparte’s Gulls, but from Marymoor they appeared pure white. In fact, in at least 20 minutes of viewing, I never once saw either one dive. However, they both were frequently making swirling swoops where they would suddenly turn and drop the the surface but then just dip their bills at the surface. I expect there was some kind of insect they were picking off the surface. From Idylwood Park, down the west side of Lake Sammamish from Marymoor, I was able to see the birds well and determine that they were juvenile Common Terns, and not gulls.

As for the HUTTON’S VIREO, I don’t know how Matt picked out some vocalizations over the loud road noise off West Lake Samm. Parkway. But I played the song, and then the call. The vireo came straight in, quite aggressively, to the call.

While COMMON TERN and HUTTON’S VIREO have each been seen fewer than 10 times at Marymoor, amazingly neither of these was new for the year.

For the day, a quite respectable 64 species.

Report for September 18, 2014                                                                                                                     Birding at Marymoor

It was dark and misty this morning, though we didn’t get rain or even drizzle, really. But it was dark, and it was QUIET, especially for the first couple of hours. Also rather steamy and moist, with temps in the 60’s, and humidity that you could practically wring out of the air.

The big highlight were 3 JAEGERS that flew past the Lake Platform heading north. This wasn’t a total surprise, since we had a Jaeger fly north on the very same day of September, back in 2008. Our consensus was that today’s birds were Long-Tailed Jaegers, for they looked slim and had very long tails. Last year, we had a Long-tailed Jaeger on August 29th for our only other Jaeger sighting at the park. However, I had a niggling suspicion that we were wrong on the identification.  I thought I'd seen chestbands and white in the wings, both features of PARASITIC JAEGER.  Ollie's photos seem to confirm that ID.  ANOTHER NEW SPECIES FOR MARYMOOR PARK.

Other highlights:

Common Loon                      One WELL out on the lake – First of fall
Osprey                                  Still 2 over the lake
Bald Eagle                             Adult at lake, after 2 week summer vacation
Wilson’s Snipe                      Again, 2 below weir
American Kestrel                  1 over mansion area, 11:20 a.m. – First of fall
Merlin                                   1 perched near mansion, 11:20 a.m, – First of fall
Willow Flycatcher                  Last of the year?1-2
Black-throated Gray Warbler Grace saw 1, south end of Dog Meadow
HOUSE SPARROW             One male at Compost Piles – First for 2014

In the last two years, we’ve had as many sightings of Jaegers (2) as House Sparrows :)

For the day, 58 species. Misses today included Green Heron, Vaux’s Swift, Barn Swallow, and Yellow-rumped Warbler.

I believe we’re up to 152 species for the year.

Report for September 19, 2013                                                                                                                     Birding at Marymoor

NOTE:  Lillian Reis was with the group, and took a photo of a bird that was mostly unnoticed by other members of the group.  The photos reveal a WESTERN SCRUB-JAY, a species seen only 2 times previously at Marymoor! See photos at the end of this post.  - Michael

The early day at Marymoor started out with low fog that obscured the view. By out start time most of it had lifted and we had a nice clear, but cold, day with lots of sunshine.

We could definitely tell we have moved into Fall with much reduced numbers of many of the birds.
Interesting birds for the day:

Barn Owl                                 Heard by Matt early
Green Heron                          Juvenile at rowing club
Fox Sparrow                           First of season
Golden-crowned Sparrow     First of season
Osprey                                     Lingering
Savannah Sparrow                Flock of 25 early all at once
Yellow Warbler                        Late
Orange-crowned Warbler      Late
Barn Swallow                          Late
Vaux's Swift                             Late
White-crowned Sparrow        Both gambelli and pugetensis subspecies

It was a good day, even with Michael in Greece.

Good Birding

Report for September 20, 2012                                                                                                                             Birding at Marymoor

We had fog for much of the morning, which may be why we didn’t see a Bald Eagle, but it cleared just as we left the lake, and we managed to find quite a few species.

Highlights:

Greater White-fronted Goose     Juvenile near windmill – First of Fall
Osprey                                      Two sightings, probably 1 bird
MERLIN                                   South end of Dog Meadow, from boardwalk
Virginia Rail                               One heard across the slough
Hairy Woodpecker                    Two together in Big Cottonwood Forest
PURPLE MARTIN                   Four over boardwalk – LATE for them to be here
Swainson’s Thrush                     One seen, a couple more heard
AMERICAN PIPIT                  Several flyovers – a dozen birds?
Golden-crowned Sparrow         First of Fall - 2+ at Pea Patch
WESTERN MEADOWLARK Ollie and Houston saw 1 near Compost Piles
Evening Grosbeak                     1 seen near windmill, flyovers heard several times

For warblers, ORANGE-CROWNED (several), YELLOW-RUMPED (a few), BLACK-THROATED GRAY (1-2), TOWNSEND’S (1), and COMMON YELLOWTHROAT (several). No flycatchers or vireos.

For the day, 57 species

Report for September 22, 2011                                                                                                                           Birding at Marymoor

It was as quiet a day as I can remember in any September this morning. We had heavy overcast, and warm wet air, though no precipitation during the walk. We also had no birds, or so it seemed at times. What we did have was often distant, heard-only, and/or fleeting.

Highlights:

Sharp-shinned Hawk                2 sightings. One sent starlings into a ball
Barn Owl                                 Matt had at least 2, as late as 6:30 a.m.
SHORT-EARED OWL           One flew over Pea Patch 7:45 a.m.
Vaux's Swift                             2 over mansion
COMMON RAVEN               2nd straight week, over lake platform
Orange-crowned Warbler        1-2
Yellow-rumped Warbler           Several, all drab
Black-throated Gray Warbler   1-2
Purple Finch                             Many, some singing
Evening Grosbeak                     Invisible flyovers

We've only had COMMON RAVEN 20 times at Marymoor, but 5 of those sightings have been in 2011.

It was a good day for mammal sightings, with COYOTE and MULE DEER as well as the usual rabbits and squirrels.

Misses for the day: We had no flycatchers or vireos. Also, no Brown Creeper, Common Yellowthroat, Fox Sparrow, or Lincoln's Sparrow, though Ollie Oliver sent me photos of a Lincoln's Sparrow from yesterday. He also photographed NORTHERN HARRIER and WESTERN MEADOWLARK yesterday.

For the day, only just 50 species, but at least 53 for the week.

Report for September 23, 2010

No rain until we got to the compost piles,  though mostly overcast. Hard rain as we walked around the mansion.  Not a great day for actually SEEING birds, but still a really good day.

We had a very sad, but very exciting start to the morning.  Brian Bell found a recently run-over (still warm) COMMON POORWILL, which he showed to all of us.  This is a new bird for the Marymoor Park list, and one that I don't think anybody expected.

Elsewise, we still had some "summer" birds, along with a few returning winter birds (a few FOF- First of Fall birds).

Highlights:

Greater White-fronted Goose        1 with Canadas - FOF
Horned Grebe                               2 well out on the lake
Western Grebe                              3 well out on the lake
Double-crested Cormorant            2 - FOF
American Kestre l                          Female or juvenile on grass soccer fields
Wilson's Snipe                               Scott heard one, East Meadow early. FOF
Vaux's Swift                                  Somewhere between 1-3, with VGSWs
Pileated Woodpecker                   Heard off to the west
Violet-green Swallow                    Large flocks (75+ total)
Barn Swallow                               1-5, with VGSWs
Orange-crowned Warbler             2+
Yellow Warbler                            2
Yellow-rumped Warbler               Fairly common
MacGillivray's Warbler ?               Ollie had a gray-headed yellowish warbler
Wilson's Warbler                          2+
Fox Sparrows                               Lots of singing, a couple of good looks
Evening Grosbeak                        25+ in one flock, plus a few more. All in flight.

Part of the group also had a close encounter with a Townsend's Vole, which was fun (ran right over my boot).

For the day, 62 species.

Report for September 18, 2008

In the morning, it was cloudy, dark, humid, almost chilly, but not windy and it didn't really even mist much. The lighting conditions weren't great, so while we had several sightings of flying ducks, identifications were uncertain.  We had at least 4 species besides Mallard, Wood Duck, and Hooded Merganser, but couldn't count anything for sure.  Maybe Gadwall, Wigeon, Pintail, Shoveler, Green-winged Teal, and Common Merganser, but in the end, only the 3 on the list.

A little after 7:00 a.m., while we were still getting out of our cars, a PARASITIC or LONG-TAILED JAEGER flew right over our heads, flying north.  I got one of the less good looks amongst those who saw it.  Here's what I saw: A gull-like bird with pointed central tail feathers.  They were not very long, but Long-tailed Jaeger don't always have long tails.  Length good for Parasitic.  The wings seemed uniformly dark on the underside, and the body was quite light.  I saw the bird only flying away, but the body seemed slender and did NOT appear to have a strong "collar" appearance on the upper chest, like a typical adult light-morph Parasitic.  In the big Sibley, the jaeger image the seems closest to my memory is the small picture of the Long-tailed Jaeger "Adult nonbreeding".  However, unless Matt Bartels or one of the others who got a better look can confirm an identification, I think it will have to go down as Jaeger sp.  Still, WAY COOL, and totally
unexpected.  We've been having a contest to predict the next new Marymoor birds that will show up.  About 15 of us predicted up to 15 species each that might appear next at Marymoor.  At total of 84 species were nominated (including some that were WAY out there).  Nobody chose a Jaeger though. Maybe sometime soon my jaw will return from the ground...

Houston Flores had a SWAINSON'S HAWK (the second Marymoor sighting ever), at around 5:00 p.m.

Other highlights:

Virginia Rail                       One seen flying a short distance below the weir
Killdeer                              Flock size up to 40
Wilson's Snipe                   One below the weir - First of Fall
Mourning Dove                  One over East Meadow
Barn Owl                           4 simultaneously in 2 different spots early
Great Horned Owl             Scott heard predawn hoots from near of Dog Central
Hairy Woodpecker            Always a good day when we see one
Swainson's Thrush              Still a couple
American Pipit                    One seen with Killdeers west of velodrome
Orange-crowned Warbler  3+
Yellow-rumped Warbler     MANY, mostly very drab
Wilson's Warbler                One at the Rowing Club
8 species of sparrows:         Towhee, Savannah, Fox, Song, Lincoln's,
                                           White-crowned, Golden-crowned, Junco
Black-headed Grosbeak      2+ still around
House Sparrow                   First since July, only 2nd since April - Joy

A great group was with me for a great day, with 58 species seen or heard.

Report for September 20, 2007

It was a good day at Marymoor today. We managed to ferret out quite a few species, including several good birds. Great looks were sometimes lacking, but that's the way birding is sometimes.

The day was overcast, and we had a couple of moments of heavy mist or light rain, but generally the weather was quite good. There were eleven birders all told.

Highlights:

Horned Grebe Two out on the lake Western Grebe Two out on the lake D.-crested Cormorant Two out on the lake Green Heron Nice adult at Rowing Club Northern Harrier Flyover at lake, later in East Meadow Cooper's Hawk 2 juveniles at Compost Piles, adult at Pea Patch American Kestrel 1 flying down the river early Spotted Sandpiper On slough from Rowing Club late Wilson's Snipe One at RC pond, one over slough earlier Vaux's Swift Several, but these should be our last of the year Pileated Woodpecker Heard calling several times; only Mason saw one HORNED LARK Three landed at east edge of grass soccer fields Evening Grosbeak Two distantly glimpsed, near the mansion

Around 6:30 a.m., Matt Bartells had a fly-over COMMON NIGHTHAWK. This is the fourth nighthawk noted over Marymoor, and all have been during Week 38: 9/17/04, 9/18/05, 9/20/05, and now 9/20/07. Pretty consistant!

The three HORNED LARK landed on the logs at the east edge of fields 7-8-9, right next to the driveway to the Interpretive Lot. We got decent looks, before they flushed out of there when one of the juvenile COOPER'S HAWKS came through. They appeared to be completely devoid of yellow coloration - does that make them Arctic birds?

We had both HERMIT THRUSH and SWAINSON'S THRUSH. They don't usually overlap much, as we usually don't get Hermits until October, just after the Swainson's leave. But we've had some September Hermits this year.

We had a six warbler day, with MANY ORANGE-CROWNED WARBLERS, one YELLOW, a handful of YELLOW-RUMPED, a single BLACK-THROATED GRAY with a single TOWNSEND'S WARBLER northeast of the mansion, and a few COMMON YELLOWTHROATS.

First of Fall FOX and GOLDEN-CROWNED SPARROWS.

For the day, 65 species.
