White-tailed deer (Odocoileus virginianus) can be found throughout Florida from the panhandle to the keys. The common name refers to the tail; it is brown above and white below. When deer are alarmed, the tails are held erect and waved back and forth like a flag, signaling a warning to other deer. White-tailed deer vary in size depending on the habitat in which they occur. Adult male deer in Florida average 115 pounds while the smaller females average 90 pounds.
