Dorsal/side view of tail, showing all-white outer webs of R6 and R5, and small white tip of R4.
COLBY WRITES: Continuing. The wind unfortunately blew up my recordings. Blue-gray above, white below, white eye ring, long thin tail with at least some white outer tail feathers that it often held partially cocked in the air. First heard and seen near the SW corner of Pintail Marsh in the trees between the dike and the Tualatin River at ~845am, but we lost it in the celebration...we thought it went to the west along the path that follows the river, but we could not relocate it when we went back around. I went on a second pass around Pintail Marsh around 1020am and heard it along the Tualatin River on the east-southeast side of Pintail Marsh, but could not locate it visually due to the sunlight. It seems to call occasionally, but definitely goes long bouts without calling. It seemed to be on its own during the first observation. ..... JAY WRITES: I have gone through my video and have created screenshots that show the tail pattern as well as possible. Based on what I see in these screenshots and understand of the eastern and western birds' plumages, I am leaning toward this bird being of the eastern subspecies, caerulea.
