White-Tailed Deer
The white-tailed deer is the largest wild animal in southern Minnesota. Its running speed is about 30 miles per hour, with a maximum of 50 m.p.h. Still, a deer depends on camouflage and its keen senses to survive.
Deer can jump exceedingly well, clearing objects 7-8 feet high from a standing position. White tails also can swim, but enter deep water only when pressed.
Deer are colored blind, seeing the world in monochromatic tones and shades of gray. They do not appear to see an object that does not move; however, the slightest movement will be seen immediately. Even the blink of a human eyelid can be enough to send the alerted deer running off to safety.
The sense of smell plays a very important role in a deer's world. Observations show that a distance of about one-third of a mile is the maximum range scent can be detected by deer. Also, their hearing is excellent. Ears are constantly in motion, picking up sounds of possible danger. Alarm calls of the blue jay, American crow or red squirrel can send a deer bounding away, tails erect and showing their "white flags."
