Subject: Journal article on Northwest rufous hummingbird arrival dates
Some on this list may have already read this article. A bird-nerd relative on
the east coast gets this journal and mailed me the article a while back. I'll
try to attach a scan of the first page and abstract. The author compared recent
e-bird data for arrival dates with some much older data from before 1969. The
conclusion drawn was that rufous hummingbirds are arriving later on the Oregon
coast at Coos Bay and Newport and earlier up in British Columbia. The author
speculates that rufous hummingbirds may be using inland routes more in recent
years and also that the birds are extending their range northward. Interesting.
