Hey Great Pictures!!!
The two piebalds in the herd near me are both female. And even though they say it is not a genetically inherited trait, I swear they are mother & daughter. I've watched the mother for the last three years and the daughter showed up a year ago. It makes them easier to spot as individuals but I haven't noticed that it detracts from their camouflage as it is still hard to spot them in the woods. I'll see if I can get some photo's this summer and post them too. I also have a melanistic black over dark grey down the road I've watched. Her young one this year was normal. Will try to get a photo of her also.
