White tail are more curious than mulies, and wander around more. Mulies are sorta on the lazy side, and stay bedded down longer. White tail bucks are more aggressive about mating than mulies.
The bucks of both species--in hilly or mountainous country--tend to bed down just below the downwind crest of a ridge, and near some sort of low cross-over or saddle of the ridge. When spooked, they go uphill and upwind. If they can't do that at first, they'll eventually circle back into the wind.
In general, white tail seem to get imprinted with an area, pretty much remaining within a section or so of land. My only mulie experience is in desert country, where lengthy travel to and from water is common. Three or four miles for a once or twice a week drink is a common pattern.
