Isn’t he beautiful? He was caught in the hills in Marin County, not all that far from me, and kept in captivity until he died in 1931.
You might think he’s purely colorless at first glance, but he isn’t. He’s more blue-silver than white, an incredible color to come shining out of a drawer of junco specimens when you’ve just spent the last few weeks measuring the same brown-and-black birds over and over. When you look close you find that hidden in those pale feathers are the whispers of normal junco coloration.
