One question I have is about the Crows. I presume that at one time they were "good" species with breeding barriers (habitat) in place. At some point, these broke down due to settlement . But, at one time in the not too distant past they were 2 species. Consequently, any sighting pre-(some date) could be presumed to be Northwestern Crow and should be retained on life-lists. They just became extinct, in some ways similar to what the swamping by Barred Owls is doing to Spotteds.

have to wonder what was wrong with the name "Mew" that neither side of the split continues with that name.

I assume county reviewers will be removing Common Gull if there are no prior records in their area (such as for "Kamchatka" Common Gull, the most likely Common Gull to reach the PNW).
