Hi all -
It was another overcast "spring" day at Marymoor, but better than normal - only a tiny bit of drizzle.
We had some nice birds throughout the day:

Black Swift - among the big flock of Vaux's, we had maybe 10 or so over the Community Garden
Spotted Sandpiper - 2 at the Rowing Club - First of Year (FOY)
Short-billed Gull - a late flock of 17 over Lake Sammamish
Western Screech-Owl - one adult, one newly fledged young, pre-dawn
Western Wood-Pewee- 1 seen, others heard, FOY
Willow Flycatcher - heard only FOY
Pacific-slope Flycatcher - 1 giving what is called the female location call - FOY
Cassin's Vireo - 1 FOY - our first since 2019
N. Rough-winged Swallow - at the garden, seemingly exploring the crevices in the cement bins like they might try to nest there??
Swainson's Thrush - still haven't seen any, but more were in today, including somme singing pre-dawn
Evening Grosbeak - 3 flyovers , FOY
Golden-crowned Sparrow - 1- getting late
Western Meadowlark - 1 in soccer fields, also late
Bullock's Oriole - 4-5 - seemed to be about 3 territories getting set up
Nashville Warbler - nice looks at 1 FOY
MacGillivray's Warbler - 1 near windmill FOY - sang and then refused to come out for views despite way too long trying to glimpse it.
Lazuli Bunting - ~7 - five males in the east meadow and 2 females in the garden

Several of those - Nashville, MacGillivray's Cassin's, and even Pac-slope aren't guaranteed any year, much less on a single day

I think if I've got things right we had 7 firsts and overall 76 species for the day.

Misses included Hooded Merganser, Rock Pigeon, Green Heron, Cliff Swallow, Western Tanager [maybe heard],
