Spent a very pleasant morning on Mary's Peak (Benton County) today, enjoying a spectacular smoke-enhanced sunrise on the drive up. Most surprising bird was an Acorn Woodpecker that I first heard, and then watched cross overhead when I was in the meadow near the cell phone towers on the lower peak (a little below the campground). Using the Species Map function in eBird, I could find only one other record of an Acorn Woodpecker on Mary's Peak, from 1977 (mid-July). On OBOL, there have been recent reports from Portland neighborhood that doesn't normally host them, and on Mt Hebo in the Coast Range in Tillamook County. Perhaps these are dispersing individuals after the breeding season?
Other highlights on the peak included a nice flock of 16 American Pipits and 2 Townsend's Solitaires. Links to 3 full eBird checklists follow.
