You can also see white-tailed deer rubs and scrapes this time of year. Male deer (bucks) are responsible for these tale-tell marks. Rubs are made when bucks rub their antlers against trees to help shed the velvet. Contrary to popular belief, it is not to "sharpen" their antlers. Scrapes are where the buck has used his front feet to scrape away the leaves and other debris from the forest floor. Scent is left from his feet, and he also may urinate near by. This is one way he communicates with other deer.
Other neat animal signs you can see in the fall are beaver scent mounds. Like the scrapes, beavers leave their scent to communicate with others of their kind. It's a very strong scent and even us humans with our puny sense of smell can catch a whiff.
Even after all the cool ways to see signs of animals, sometimes its nice to see the real deal.
