The species has been on the Oregon coast for nearly 50 years. I first saw one at the island of timber on Bayocean spit,Tillamook with Fred Ramsey on the 1976 CBC. Dave Irons and team saw one at Oceanside, Cape Meare's flip side, on another mid 70s CBC. The isolated forest at Bayocean is miles from a human habitation. Anna's Hummingbirds colonized the Oregon Coast decades ahead of Scrub Jays, and with much less dependence on humans. About six years ago there were single digit temperatures in the Willamette Valley the first week of December. Apparently some of the Anna's Hummingbirds in Bend survived that. Conditions at sea level in southeast Alaska presumably never get that extreme.
