Report for July 20, 2023                                                                                                                   Birding at Marymoor

It was a nice a day as possible at Marymoor today: temps in the 60's - 70's, clear blue sky, hint of breeze.  Breeding season is wrapping up, and we saw the first signs of post-breeding dispersal; we saw a few species that don't actually breed in the park.  Total number of birds was actually not that high, possibly since some of our breeders are off on their own post-breeding dispersal.

  • Caspian Tern - One fishing on the lake appeared to be a juvenile
  • Great Blue Heron - Fewer than 10 occupied nests, and not that many birds seen foraging at the park
  • Green Heron - Two present, and heard them call about 4 times.  Slough below the weir, and later from the Lake Platform
  • OLIVE-SIDED FLYCATCHER - Scott got a good recording of a song from across the slough.  Unseen, but unmistakable Quick Three Beers
  • Purple Martin - Appear to be active still at both the gourds and in the snags west of the slough
  • Black-throated Gray Warbler - Adult feeding a juvenile along Dog Meadow edge
  • Western Tanager - Adult male, southwest edge of Dog Meadow
Misses today included Red-tailed Hawk, Warbling Vireo, Violet-green Swallow, Cliff Swallow, Bushtit, and Red-winged Blackbird

Even with those misses, we had 58 species today plus "dark wing-tipped gull".  We also had beaver and a deer.

Report for July 21, 2022                                                                                                                   Birding at Marymoor

Another gorgeous summer day, with temps running from 60-70 degrees, and few clouds.  Fairly birdy.  We're just beginning to get the start of post-breeding dispersal, so we had a few birds we haven't seen in a while.

  • Gadwall - One female with Mallards.  We probably often overlook these, since they are hard to ID at this time of year
  • Pied-billed Grebe - Two from Lake Platform.  First since mid-May
  • Virginia Rail - At least 4, and we got to see the one on our side of the slough near the start of the boardwalk.  First since mid-May
  • Spotted Sandpiper - One on weir.  Our only other sighting for 2022 was mid-May
  • Green Heron - Finally, one below weir, one at Rowing Club.  First of Year (FOY)
  • Red-breasted Sapsucker - At least three
  • Hairy Woodpecker - Two, completing our 4 woodpecker species day
  • Violet-green Swallow - ONLY ONE
  • BANK SWALLOW - One from Lake Platform (FOY).  Only our 13th record for this species at Marymoor
  • Swainson's Thrush - Still quite a bit of singing, plus saw about 3 on bug catching on the trail
  • Purple Finch - Some singing, plus 3-4 juveniles in the East Meadow
  • Bullock's Oriole - Adult male(s), plus 1-2 more scattered around the slough
  • Black-throated Gray Warbler - Two between Dog Meadow and slough
  • Western Tanager - One or more at the Rowing Club
  • Lazuli Bunting - One singing male, northwest corner of Dog Meadow near portapotties
Our mammal list included American Beaver, Raccoon, and Bat.  We failed to see a squirrel.

Misses today included Hooded Merganser, Rock Pigeon, Rufous Hummingbird, Red-tailed Hawk, Barn Owl, Cliff Swallow, and Black-headed Grosbeak.

For the day, 60 species.

Report for July 19, 2018                                                                                                                    Birding at Marymoor

Cooler temps, and a gloomy overcast that threatened rain, added to the end-of-breeding-season quiet, making birding somewhat uneventful and QUIET today.

We’re definitely seeing shifts in bird populations, such as large flocks of European Starlings and House Finches, and a large drop in the numbers of Great Blue Herons. In general, we found fewer birds, less singing, and few good views today. Many species were only glimpsed, with some just barely heard. Swainson’s Thrush and Willow Flycatcher were both present in pretty good numbers still, but both were doing more whits than songs, and neither species was seen.


  • Wood Duck – again, at least one clutch of tiny ducklings – every week there’re more
  • BLACK SWIFT – three or four overhead briefly, but close
  • Rufous Hummingbird – only one, a juvenile at the Pea Patch
  • Killdeer – adult with two chicks below weir
  • Spotted Sandpiper – adult near two chicks below the weir
  • Great Blue Heron – heronry empty or nearly empty; birds dispersed
  • Cooper’s Hawk – one aggressively chased an adult Bald Eagle – nesting nearby?
  • Barn Owl – Matt heard juvenile in windmill very early, again
  • Western Screech-Owl – two heard, adult seen, early
  • Tree Swallow – only one seen, but entering a nest box in East Meadow
  • Northern Rough-winged Swallow – one over fields 7-8-9
  • BANK SWALLOW – at least two over fields 7-8-9
  • Savannah Sparrow – at least a few juveniles
  • White-crowned Sparrow – at least 2 young-looking juveniles
  • BLACK-THROATED GRAY WARBLER – one seen 1500 feet downstream of weir along slough
  • Yellow Warbler – one made a couple of half-hearted songs, unseen
  • Western Tanager – adult male East Meadow south end, another singing near windmill
  • Black-headed Grosbeak – only one seen, another heard
  • LAZULI BUNTING – male north of fields 7-8-9; probably will leave soon

Critters seen included dozens of Eastern Cottontails, Matt had a Mule Deer, and a few of us spotted a LONG-TAILED WEASEL at the north end of the East Meadow.

Misses today included Rock Pigeon, Green Heron, Warbling Vireo, Cliff Swallow, and Marsh Wren.

For the day, 61 species. Bank Swallow was new for 2018 for us, but has been previously reported on eBird this year.

Report for July 20, 2017                                                                                                                   Birding at Marymoor

Mostly cloudy and a bit breezy, and QUIET. We’re pretty much into the post-breeding lull; birds have left the park, and not much has moved in. Really noticeable change from last week, though some of what we missed today might just have been that we missed them.


  • Rufous Hummingbird – two at south end of Dog Meadow, after zero last 2 weeks
  • Spotted Sandpiper – at least 1 adult, at least 2 babies, at weir
  • Great Blue Heron – could only see 2-3 still-active nests in the heronry
  • Osprey – especially numerous; young may have fledged from both nearby nests
  • Cooper’s Hawk – Dog meadow, caught *something* that was approximately robin-sized
  • Barn Owl – As late as 5:10 in the East Meadow
  • WESTERN SCREECH-OWL – baby just SE of East Footbridge!
  • Hairy Woodpecker – flew across Dog Meadow
  • MERLIN – flew low over boardwalk, causing consternation amongst swallows
  • BANK SWALLOW – one from Lake Platform

Brian and I found the WESTERN SCREECH-OWL at 4:30 precisely one of the places adult Screech were frequently seen this spring (near the old “willow” interpretive sign). It was fledged, but still in juvenile plumage, very similar to this photo from Paws:  I believe this makes the baby somewhere in the 4-6 week-old range. We did not see an adult nearby, but as it was still very dark, there may well have been one. Given that we had a pair of adult Screech-Owls well into May, and now (at a date just perfect for incubation+fledging) we have a juvenile, it appears highly likely that they nested in that immediate area!

At the Lake Platform, we stood around for AT LEAST 10 minutes, with no sign of any PURPLE MARTINS. Then, just as we were about to leave, two emerged from the gourd(s), surprising us all.

The really notable thing today was all of the species we didn’t find, or where the numbers were WAY down from last week. We had only a single WESTERN WOOD-PEWEE, and that was heard-only. Misses included Chestnut-backed Chickadee, Red-breasted Nuthatch, Purple Finch (might have heard one), Yellow Warbler and Yellow-rumped Warbler (or indeed any warbler besides Common Yellowthroat), Black-headed Grosbeak !!!, Lazuli Bunting, and Brown-headed Cowbird.

On the mammal front, Brian and I had myotis sp. bats from the boardwalk.

For the day, just 54 species.

Western Screech-Owl,
juvenile plumage - 5 to 8 weeks old perhaps? Overall very gray. Fine, dense, medium-gray horizontal barring on frontside, darker crown. Did not appear to have fuzzy down on head, so not real, real young.

Report for July 21, 2016                                                                                              Birding at Marymoor

A glorious day today, with perfect temperatures, sunshine, and BIRDS. Lots of babies, lots to be seen.


Wood Duck                        Two clutches of ducklings
Mallard                               Female with tiny ducklings at lake. 2nd clutch?
Great Blue Heron                Still at least 1 baby on nest
Green Heron                       At least 3, 2 adults, 1 subadult
Cooper’s Hawk                  Juvenile and adult seen
Spotted Sandpiper              1 adult, 2 juveniles below weir: breeding confirmation| GR. YELLOWLEGS         1 called twice – First of Year
CASPIAN TERN              Twice had single birds flying downslough – FOY
- all 5 woodpeckers -        
Tree Swallow                      Female at Lake Platform gourd nest|
Orange-crowned Warbler    First of Fall, one along west edge of Dog Meadow
Yellow-rumped Warbler      Might be nesting east of mansion
Bl.-throated Gray Warbler   5-6 along west edge of Dog Meadow, most juv.
Spotted Towhee                  Many juvs., also adult feeding cowbird :(
Western Tanager                 2 different adult males
Bullock’s Oriole                  2 heard
EVENING GROSBEAK    Flock of 10 over Dog Meadow – FOF

At the Rowing Club, we had 2 adult GREEN HERONS at the pond, and between the pond and the row house, we had a large family flock of BUSHTITS. The baby bushtits crammed all along one branch in a chain of at least 10 babies, all touching. Parents were coming in and feeding. Even Matt said we could call them “cute”.

Non-birds included pre-dawn COYOTE, lots of bunnies, one AMERICAN BEAVER, and a good number of GARTER SNAKES. 8-spotted skimmer dragonflies were all around and over the Rowing Club ponds and the slough.

Misses for the day included Pied-billed Grebe, Rock Pigeon, Yellow Warbler, and Red-winged Blackbird. Even so, we managed to find 64 species. Adding GREATER YELLOWLEGS and CASPIAN TERN gets us to 136 species for the year, I believe.

Report for July 16, 2015                                                                                                                     Birding at Marymoor

It was a pleasant morning to walk around today, as the overcast kept the temperatures down in the ‘60’s. No bright glare either. We are officially in The Summer Doldrums, but even the doldrums are good at Marymoor.


Canada Goose                            Actually saw one this week :)
Great Blue Heron                        Almost all the nests empty
Green Heron                               2 sightings – same juvenile both times?
MERLIN                                    Caused quite the uproar amongst swallows
Purple Martin                              Next exchanges at Lake Platform gourd
Tree Swallow                              Still active at 1 nest; overall, very few
Violet-green Swallow                  Close to 100
Barn Swallow                             Close to 100
Yellow-rumped Warbler             Extremely drab juvenile
Black-throated Gray Warbler      1-2
Lazuli Bunting                              2-3 juveniles near Compost Piles, early

I also saw a MINK on the far shore of the slough, a bit above the weir.

For the week, 59 species.

Report for July 17, 2014                                                                                                                     Birding at Marymoor

It was bloody COLD this morning, especially pre-dawn when we also had a stiff wind in our faces (okay, okay, it was 59, but with the wind chill, that’s cold). I arrived 30 seconds too late to see the BARN OWL the others were watching. So much for getting up at 4:00 a.m. There wasn’t much else around pre-dawn except for the crows that appeared just after I arrived. As our walk started, the wind died down a bit, but the clouds thickened, and it never really got warm. Pretty quiet too, and one of the most notable things was the decrease in singing from last week; e.g. very few WILLOW FLYCATCHERS singing, and no BLACK-HEADED GROSBEAK songs, though we did see both species.


Great Blue Heron           Seem to have finished nesting; fencing already removed
Spotted Sandpiper         One at the weir
- gull sp. -                      One bird early, with black wing-tips. Ring-billed?
Caspian Tern                 Quick glimpse of 1 bird flying north over slough
Rufous Hummingbird      Still at least 3; should tail off through August
Pacific-slope Flycatcher One at south end of Dog Meadow, silent
Or.-crowned Warbler?   Juvenile warbler(s) gave us many terrible looks
Yellow-rumped Warbler At least 2
Black-thr. Gray Warbler At least 3, near PSFL and the questionable warbler(s)
Wilson’s Warbler           1-2, also with flock at south end of Dog Meadow

The mixed flock at the south end of the Dog Meadow was the highlight of the day. Great look at the Pacific-slope Flycatcher and then it disappeared, leaving us with BLACK-CAPPED CHICKADEES and BLACK-THROATED GRAY WARBLERS. We were following these north along the west edge of the meadow and found the WILSON’S WARBLER(s) and the mystery warbler(s). Many birds were present, and it was a real challenge to stay on any one bird. Things got way worse when the warbler/chickadee flock merged with a flock of BUSHTITS and headed back south. Now there were twice as many really active birds birds.

Our mystery warbler(s) never gave us more than partial looks. At various times, I saw white undertail coverts; wings with either wing-bars or at least some feathers with white edges; yellow wash over the head, throat, and breast; plain greenish wings (hence my belief that there was more than one bird); a grayish head; a yellowish head; a thickish, longish, blackish warbler bill; kind-of-maybe-an-eye-line. None of the views of this presumed hatch-year bird looked right for Yellow nor for Wilson’s. Sometimes the plumage looked right for Tennessee, but the bill and body looked too big. Our last look seemed really good for Orange-crowned Warbler, except for the whitish undertail coverts. Dang birds.

Ollie went back after the walk to try and refind the bird, but found no flock at all. His only consolation prize was a COMMON MERGANSER (rare for this time of year at Marymoor) which, along with my lone ROCK PIGEON under SR-520 as I left, brought our day total to 61 species. I believe we’re still at 139 for 2014.

Our best other sighting was a LONG-TAILED WEASEL which popped out repeatedly while we were busy looking at the warbler flock!

Report for July 18, 2013                                                                                                                              Birding at Marymoor

60 degrees and overcast? July, huh? Meh. It did NOT feel like summer.  Still we had a pretty nice walk around the park.

At the lake platform, we could find no eagles, but did see an OSPREY carrying a fish back towards the nest (where 3 young were awaiting breakfast). Suddenly, two adult BALD EAGLES appeared. The osprey had at least a 100 yard lead, but the fish must have been pretty heavy. It took only about 20 seconds for the eagles to overtake the osprey. The first eagle appeared to fly under and in front of the osprey, while the second trailed below and just behind the osprey. Realizing he was surrounded, the osprey dropped the fish. The trailing eagle smoothly rotated feet-up and snagged the fish.

Later, we saw the two adult eagles sitting side by side in a tall cottonwood, one vocalizing loudly. They may already have eaten the fish by that point.

When we were at the Viewing Mound, an adult Bald Eagle flew very low over the mound and then swooped to the ground, grabbing a large clump of dried weeds, which it carried off (presumably for nesting material ?!?!?) The weeds must have been heavy and caused a lot of drag, for the eagle flew low and ponderously over the Dog Meadow. An osprey then flew fast across the meadow and took a swipe at the eagle, causing it to drop its weeds! What goes around comes around.

Other highlights:

Great Blue Heron        Heronry is empty.
                                   Heron numbers down from 20 to about ~4
Virginia Rail                Two heard from far side of slough near lake
Caspian Tern              Two flew down high over the river
Cooper’s Hawk          Immature at Compost Piles
Rufous Hummingbird   Female and/or immature at Pea Patch
MERLIN                    Annoyed the swallows over the East and Dog Meadows
N. R-winged Swallow Probably 2 or more

For mammals, we had several MUSKRAT and a LONG-TAILED WEASEL

For the day, 57 species.

Report for July 19, 2012                                                                                                                             Birding at Marymoor

We had nice weather, but it was very quiet today at Marymoor. A few species were singing constantly: Willow Flycatcher, Western Wood-Pewee, Bewick's and Marsh Wrens, Swainson's Thrush, and Common Yellowthroat, but there wasn't a whole lot else. Even those species were not very easy to see. Still, we walked the loop slowly and carefully, and managed to find some birds.


Canada Goose                   Flight lessons for young birds
Cooper's Hawk                 Only our 2nd since April. With prey.
Barn Owl                           Matt had 4-5, including babies near the windmill, early
Cassin's Vireo                    One singing, near dog swim beach 3
N. Rough-winged Swallow 1-2 near grass soccer fields
Brewer's Blackbird             1 female on grass soccer fields
American Beaver                1 in slough at swim beach 3

The CANADA GEESE were learning to do the over-and-back half barrel roll used to "dump air", allowing a quick drop in altitude. This was a family-sized group, and there was no particular reason to be using that flight technique where they were flying, which was fairly low over the weir.


For the day, 56 species. BREWER'S BLACKBIRD appears to be new for our 2012 list.

Report for July 21, 2011                                                                                                                           Birding at Marymoor

I usually try to start our walks soon after sunrise. I was pushing things a bit by starting this morning a few minutes before the 5:33 a.m. official sunrise. It didn't really matter. It was dark before sunrise. It was dark long after sunrise. Heavy overcast, quite a bit of mist, mizzle, drizzle, and a little bit of almost rain this morning. Birds were hard to see, and there wasn't much singing. There were lots of awkward-looking juveniles about, and quite a few fledglings begging for food. But by the end of the morning, we had the largest species count we've had since early June. Go figure.


Green Heron                        Several sightings
MERLIN                             Matt saw one dart across the grass soccer fields
Caspian Tern                       Four flew down to the lake
Black Swift                          Three briefly seen during a moment without rain
Hairy Woodpecker              Male near last dog swim beach
Purple Martin                       One in right gourd at lake platform
Orange-crowned Warbler    One along Snag Row - juvenile?
Bullock's Oriole                    3-5, adult male(s?), adult female, juvenile(s?)
Pine Siskin                           Heard over mansion area

For the day, 63 species, though the numbers for each species were often pretty low.

Report for July 22, 2010

It was cold, with heavy overcast, breezy, and at times misty at Marymoor this morning.  Add in the late-summer blahs, and it wasn't our most exciting day at the park.

  • Matt heard the WESTERN SCREECH-OWL near the windmill at about 4:10 a.m.  I didn't hear my alarm clock until 4:45 a.m., so I can't confirm.

  • Lots of WOOD DUCK babies, in a variety of sizes.

  • We had 1 or 2 juvenile RED-BREASTED SAPSUCKERS.  One was getting red on the face, but the rest of the head was still dark gray.

  • The Least Flycatcher was not heard this morning.  Maybe he only sings on sunny days.

  • Still lots of WILLOW FLYCATCHER and SWAINSON'S THRUSH singing.  BLACK-HEADED GROSBEAK numbers are way down, though.  We had a YELLOW-RUMPED WARBLER near the barns.

  • There were many juvenile (and a few adult) WHITE-CROWNED SPARROWS in the Pea Patch, along with many ANNA'S HUMMINGBIRDS and HOUSE FINCHES.

  • At the end of the morning, we had a tight, swirling flock of small gulls that looked to me to be MEW GULL, but that could not be confirmed, as they rose up and disappeared into the clouds.

For the day, 56 species were noted.  It was a group effort (translation: several species were seen only by 1-2 people).

Report for July 16, 2009

It was a really nice summer day.  Unfortunately, I had to leave after only 2 hours to take my son to the airport, so Brian Bell compiled the list for the day.


The male RING-NECKED PHEASANT was seen early on the grass fields, and heard later.

We had one CALIFORNIA GULL fly down the slough at about 6:00 a.m.

We had our first-ever July sighting of PILEATED WOODPECKER, calling and seen flying west of the park.

Sharon Aagaard found a juvenile BARN OWL in the maple tree next to the nest box, straight above the path.  The rest of us had given up on finding one.  It appears that only a single baby was fledged this year from the nest box.

BROWN CREEPER was heard singing; later, a family with adult and juveniles was seen.

At least one LAZULI BUNTING was still singing near the Compost Piles.

BULLOCK'S ORIOLE:  Brian noted "2 or 3 males, female, several young being fed, including one without a tail"

For the day, I think 56 species.

Report for July 17, 2008

It was chilly, a touch breezy, and more overcast than I was expecting this morning.  We're in the doldrums - nothing unusual expected or found - but the park still has it's attractions.  We had a really good day.

The first highlight were three RIVER OTTERS actively fishing (or crawfishing perhaps) in the slough above the weir.  They gave a great show.

We had a STELLER'S JAY already going after the very green Hazelnuts

One CASPIAN TERN was over the lake

Nice looks at a RED-EYED VIREO north of the east end of the boardwalk

And then there were the babies:

Wood Duck                      3 clutches of ducklings
Green Heron                     5 fledged young at Rowing Club with adult
Osprey                              2 babies on nest
Cooper's Hawk                 3 babies and adult
Red-tailed Hawk               Watched a very awkward landing!
Warbling Vireo                  Baby being fed at Rowing Club

The COOPER'S HAWK nest lay on the ground under the tree it was in.  The three babies were in the trees nearby, two together and a third a little apart.  An adult was seen leaving the scene.

The five fledged GREEN HERONS were at the main pond at the Rowing Club, flying (and especially landing) awkwardly.  One was thinking about trying to fish, but was working from a branch too high above the water.  The rest seemed willing to wait for Mom or Dad to deliver.  An adult did arrive and was mobbed.

Report for July 19, 2007

Eight of us enjoyed a pleasant and interesting morning at Marymoor. As we move into the post-breeding period, a few new things are moving in/through.  The weather was overcast, but clearing (no rain, no wind).


Green Heron                            Multiple sightings, at least 2 adults
GREATER YELLOWLEGS    Flyby, with kingfishers.  Only 3rd ever.
Mourning Dove                        1st of 2007, in Snag Row
Belted Kingfisher                      At least 3, seen together
WILSON'S WARBLER          First of fall, several

At about 5:45 a.m., to BELTED KINGFISHERS flew north over the South Lot.  A third bird flying with them looked slightly different - pointed wings, a thinner bill, trailing legs - Just as I got on it, it gave the tew-tew-tew call of a GREATER YELLOWLEGS.  In a weird deja vu moment, five hours later, as we came back through the South Lot, three birds flew north.  This time, all three were kingfishers.

Lots and lots of babies of just about everything.  Trees dripping with young  VIOLET-GREEN SWALLOWS.  Ducklings (MALLARD, WOODIE, HOODIE), Goslings, wrens, finches, etc.  Young warblers were a bit of a challenge to ID - certainly several COMMON YELLOWTHROATS, at least one YELLOW WARBLER, maybe a WILSON'S...

Anyway, a good day.  For the day, including the LEAST FLYCATCHER (see below), 61 species.  The Mourning Dove and the Greater Yellowlegs were new for 2007.

Today [2007-07-19] we couldn't do the early morning walk but we got out there later and did an abbreviated version of it. we found the LEAST FLYCATCHER calling at the compost mounds in a large willow (?) tree surrounded by blackberries. he was doing his "chebeck" call quite a bit so he should not be to hard to find. we last saw him at about 11:50.
