Where are the birds?

Varied thrush

Mountain Chickadee

It's in the middle of winter and we have a spot or two of snow.  The bird feeders are full of luscious black sunflower seeds.  About two weeks ago I filled the feeders.  Our neighbor squirrel came over, and not able to get to the seeds, provided the longest harangue I ever heard in our forest.  But ever since that announcement or complaint, nary a bird.

The above pictures show the typical birds we were seeing every day only a little while ago.  Photos courtesy of http://www.allaboutbirds.org/guide/search
