Hi Tweets -
After we finished the walk today, Michael headed directly to the WOS conference, so I’ll be doing the write-up.
Today we had a beautiful May day at Marymoor. This is traditionally one of the weeks with the highest number to species recorded at Marymoor over the years, so we were open to anything showing up. We didn’t record a particularly high total species count in the end, but there were some nice surprises for the 4 of us who joined in for the walk.
Highlights:
Great Egret - one flew over our heads while at the weir. Then later it returned and perched near the heron rookery for quite a while for nice views. This in only our 3rd or 4th Marymoor record, and the first since 2020.
Great Blue Heron - many young on the nests, and one or two fledged and in the slough, looking awkward as they learn to fish.
Western Wood-Pewee - heard a few and saw one - first of year (FOY)
Willow Flycatcher - one heard only, around dawn. FOY
empid sp. - one that got away along the slough that looked enticing
Swainson’s Thrush - many calling and some in full song, before dawn. Once the sun rose, only heard one or two calling during the walk
Bullock’s Oriole - one first year bird for another FOY
Wilson’s Warbler - particularly numerous today - we seemed to be able to hear one singing at almost any point in the walk.
Black-headed Grosbeak - competed with Wilson’s Warbler for one of the most numerous singers today.
Lazuli Bunting - a couple around, but not particularly cooperative
ducklings - several clutches of Mallards swimming around
Misses today were numerous, including most ducks, Green Heron, Downy & Hairy Woodpecker
For the day, about 57 species - with 4 FOY birds, I think that brings us to 107 for the walk year list
