A couple years ago we discussed on tweeters whether the El Nino cycle
had an effect on Snowy Owl numbers in Washington. The current El Nino
is now beginning to show its appearance in our area:

Following the scientific method, it might be interesting before the
fact to speculate on what might be possible: there is evidence that
in the falls coming after sufficiently strong El Nino events there
are corresponding good flight years for Snowy Owls in Washington.

Thoughts?
