My migration plots are interesting but for every species there are
anomalies. For CLSW, from S. to N.: Olympia 3/19, Tacoma 4/2, Vancouver,WA
4/3, Seattle 4/3, Spencer Is. 3/24, Skagit W.R. 3/23, Bellingham
(4/6-4/14), Vancouver (Reifel + Iona) 4/10. Overall, not too bad a trend
but Spencer-Skagit birds must have had a tailwind. For E. of Cascades, I
have Ft. Boise, ID 3/23 and Tri Cities 3/22. For BASW, Forest Grove, OR
1/28!, Tacoma 4/2, Spencer Is. 3/24, Bellingham (4/6-4/14), Vancouver 4/10.
For E. side, Ft. Boise, ID 3/23. For VGSW, Forest Grove 1/28, Spencer Is.
1/27!!!!!, Bellingham 2/24, Vancouver (avg. date=3/1), Port Alberni 3/2.
For E. side: Ft. Boise 3/23, Tri Cities 3/22. Yakima 3/15, Malott 2/18!!!!,
Winthrop 3/16, Calgary 4/3. For RWSW: Seattle 3/23, Spencer Is. 3/24,
Skagit Co. 3/23, Bellingham (4/6-4/14), and Vancouver 4/10. For E. side:
Ft. Boise 3/23. Need more data on all of these species, especially in
Canada and on E. side of mountains. Many thanks for your many postings!
