Acorn Woodpecker at Lake Lagunitas this afternoon.
The Acorn Woodpecker is the only species that regularly drills holes for food storage, caching acorns in trees, telephone poles, or fence posts. These sites are referred to as granaries. The Acorn Woodpecker is a communal, cooperative breeder, with groups of birds filling, using, and defending granaries.
And it occurs to me that, if we had Woodpecker brains, we wouldn't be in the economic pickle we find ourselves in.
