Cassin's Finches invaded central Colorado's Ponderosa mountains west of the Springs last fall and were still around here just a few weeks ago in huge numbers. I was birding Ponderosa Pine forests near Boulder a couple months ago and didn't have any Cassin's Finches, so I wonder if the recent invasion into Boulder is due to finally depleting most of the Ponderosa Pine crop down here.
