I live about the Wind River and all along the river is farm land. Seeing herds of deer on those fields is common. The White Tails don't expose themselves as much as the mule deer do but in the early mornings it's common to see the 2 species of deer in what looks like the same herd. I think it's more likely that 2 herds are simply eating the same feed on the same field because even in the times we see them close together you'll not see them evenly mixed. So there may be 20 WTs and 40 Mule deer but the Whitetails groups up and the mule deer scatter out more. So them hearing together is not actually what they are intending to do. More like neighbors running to each other at the grocery store.
