I think Anna’s Hummingbird has to be the winner here. They now tally hundreds on the Victoria, B.C. Christmas Bird Count and have for some time. If Barred Owl weren’t nocturnal and we could better appreciate their density it would likely be the runner-up. Both of these species far outpace Black Phoebe in terms if both geographic distribution and numbers in Oregon.
Would you say that Black Phoebes as a native North American species have had the fastest breeding range expansion into Oregon? The only other one I can think of is Barred Owl. Any more off the top of your head?
