RE: Whitetail "tail" question
On alert they will put it up but also flare it....
I've seen this behavior in bucks before, specifically when called. It's a stimulated response, Also, I've seen it straight out and pumping....that's a very good sign you've stimulated them. I'm no biologist but to me, like taking flight, they are just showing themselfs...look at me....here I am.....I'm not tucked...etc...
