    Ah, yes the typical warm, furry-feathery bias. It’s a nice patch (probably a clone) of Equisetum (hymale?). Oh and there’s an animal there too.

    It’s a Dusky Grouse, a female. Fieldmarks include the yellow combs over the eyes and bluish-gray belly.

    Also, the location of the bird helps rule out a lot of other grouse. Ruffed Grouse I think is the only overlapping grouse, and they have a distinct white line on either side of the eye.

    I knew what it wasn’t (Ruffed, Sage, or any prairie grouse), but I had to consult my Sibley to figure it out and I think Andy is right, a female Blue (Dusky) Grouse.
