The behaviour you indicated is a doe in heat/very close. They will squat to urinate on the ground and gland area, will lick the gland area and they will lick branchs all in a effort to attract boyfriends.

Last year while mulie hunting I watched a string of does in a wide open hay meadow all do this behaviour, your right it was quite comical to see 6 or 7 does come out of the willows and do this squating thing. Less than a hour later the first of 4 bucks appeared nose to the ground on the trail of the honeys.
