Apropos of nothing, here are 12 #birds that aren't dismantling the democratic order. #birdsky #1: Acorn Woodpecker Once accused of communism. Even used to be called the "California Woodpecker," amirite? And yet, not dismantling the democratic order.
A male Acorn Woodpecker perched at the entrance of its nest cavity. The bird has a streaked breast and a bold, clown-like color pattern on its head and face. This individual has colored bands on its legs, used for identification in a research study.Screen grab of the first page of a paper published in 1924 in the ornithology journal The Condor, entitled "Communism in the California Woodpecker."
