Myth- Human urine drives away deer. (It is actually an attractant)

Myth- Deer can locate you if you make a brief sound. (In truth, deer have to focus their hearing, brief quick sounds, while heard by deer, do not give your location away. Deer have independently moving ears and they have to "focus" their hearing. This is why deer will often look in the wrong direction at a gun shot or other brief noise.)

Human's hearing, while not as sharp as a deer, is always in focus. A human can hear a little pop and immediately know where it came from.
