Thats crazy. Thanks for all the feedback, I learn something new every year!I've seen them eat charred wood, there is a massive mineral release after a fire. So all of the new growth for the first few years draws them in for two reasons, high nutrient content, and the fresh new growth.
And then the Forest service comes in and sprays for weeds after fires, this draws in animals too, and ruins any benefit that fire may have had for wildlife.
