Any day now, the Pine Grosbeaks should be moving back into northern Minnesota for the winter. That is their idea of a southern vacation. Pine Grosbeaks spend most of the season in Canada where they breed, but come October and November, they start to wander south. One of the foods that they favor are the seeds of the Ash tree.
I watch these trees in particular during the late fall, because that is where it seems the first of the Pine Grosbeaks will stop and eat.
