Nice link to the white “cream” coyotes. Maybe spontaneous or maybe Miley’s kin did get around. Nice outcome either way. I like the black “charcoal grey” wolves very much too. Boring when the pack all looks the same.
Bears can cross breed too. Pizzles have been shot. If the white black bears are better at fishing it might have been from a young male polar bear traveling to the island and siring at least one litter. Or a pipeline worker or fisherman setting a too big and mean to be a pet anymore polar bear loose on the island. It would only take one litter to change the future of bears there. Even if the hybrids were the color of the darker parent, they could have the polar bear’s water skills and hybrid vigor.
There are cream moose too. They don’t appear to have crossed with anything, just a genetic change to cream. There are creams and total albinos in snakes, birds, fish, and plants. Total albinos in plants die, but variegated plants live.
People love to see the strange and different – so long as it doesn’t try to bite them.
