Depends where you live and the deer state of mind.

Around here the deer are peaceful and play hide and seek with peoples pet cats.

They tend to make a low murmur when speaking to each other almost a mooing type sound.

They have nothing to fear in the area so you don't hear them making "alert" sounds, might be different if I was out in the hunting areas. But never heard a white tail bark like that around here.

Seen an albino one, even had them sneeze... but no barking here.
