The Florida black bear (Ursus americanus floridanus) is black with a brown muzzle, weighing up to 400 pounds. Black bears are active during the day, particularly in the early morning and evening hours. Bears roam large areas in search of a mate or food. About 80 percent of a black bear's diet consists of vegetative matter, including roots, berries and nuts, but they also eat insects and small animals. They have long, sharp claws that enable them to climb trees for food or protection.
Sharing much of their habitat with people, bears are often considered a nuisance because they raid garbage cans and bird feeders at times when natural food is in short supply. The Florida black bear is listed as a threatened species and has been documented using the upland habitats within Rookery Bay Reserve.
