About the White-tailed Deer

The white-tailed deer is the most abundant large wild mammal in North America, estimated at 30 million individuals. When alarmed, it raises its white tail like a flag — a signal that warns nearby deer and may startle predators long enough to escape. Does give birth to spotted fawns that are virtually odourless for the first weeks of life, helping them hide from predators. Bucks grow a new set of antlers each year, shedding the velvet in late summer, and engage in sparring during the autumn rut.
