Hi Tweets,

A group of biologists here at work were discussing avifaunal changes in the
past twenty years in relation to global warming, and other influences.
Dennis Paulson and I think Klaus Richter have previously discussed this
issue. Anyhow, we started a list of bird species we believe have expanded
their range into Washington in the last twenty years:

Canada goose
Eurasian widgeon
Anna's hummingbird
Barred owl
White tailed kite
Red shouldered hawk
Scrub jay
Tricolored blackbird
Acorn woodpecker
Lesser goldfinch
Black Phoebe
Eurasian collared dove

Does anyone have any additions (subtractions??) for this list?
