Bob (and Tweeters),



You may have confounded the issue by including Snowy Owl counts from east of
the Cascades. Snowy Owl numbers in eastern Washington, unlike those west of
the Cascades, tend not to show strong year-to-year fluctuations (although
there have been higher numbers in E WA this year). I believe there is some
evidence that Snowy Owls wintering east of the Cascades come from a
different breeding area (northern Alaska) than those wintering west of the
Cascades (western Alaska, especially the Yukon-Kuskokwim Delta). Even if the
Snowy Owl irruptions are related to lemming cycles, the lemming numbers in
these two breeding areas may peak in different years.
