Leucistic dusky grouse

The blue grouse I grew up with has fallen prey to the splitters (yes, yes, I've heard- DNA, distinct geographical populations, etc. etc.), and now is the dusky grouse.

Recently, A and I were up in the north central mountains of NM looking for edible mushrooms when we came across a leucistic grouse, of the now dusky variety, part of a family group or covey.

A normally colored member of the covey:

What a cool variation. I hope the white bird makes it through the season and is able to pass those genes along.
