Many of us are aware of the southern "pockets" of Common Ravens along the
south/western edge of Sherburne Refuge (including Ann Lake), and Carlos
Avery.
Today I heard a Common Raven calling on the south side of Princeton, 12+
miles from their typical areas. I also seem to remember an MOU post about a
significant number seen on either the Isanti or Chisago CBC.
I'm wondering if we're beginning to see evidence of a more southerly
distribution, or if ravens simply cover a wide area in their daily
feeding/travels. Thoughts?

PS By the way, where did all those "boreal birds" visiting in December go?
Can't even find a redpoll, siskin or waxwing in the area this month.
