It was a typical day in the neighborhood of Magnolia Plantation — a subdivision of about 500 houses in Lake Mary, just north of Orlando — where the three-legged bear makes himself at home so often that residents have given him a name befitting a creature with just a trio of limbs: Tripod.

People who live in Central Florida and in other parts of the state have become accustomed to visits by wildlife that wander, like bears and deer, or slither, like snakes, into yards, defying the man-made concept of property lines imposed on land abutting reserves and forests.

Burmese pythons, Argentine lizards, alligators, peacocks, tree frogs and spiny-tailed iguanas invade gardens, splash in pools and jostle garbage cans.

In 2014, after a Lake Mary woman was mauled in her garage, several bears who appeared habituated and dangerous to humans were put down, local news reports said.

It is illegal to feed them, and residents are told to use bear-resistant garbage cans and to avoid unintentionally attracting them by keeping pet food inside their homes.

And beware the season: At this time of year, bears are seeking to consume up to 20,000 calories a day to prepare for winter and food shortages, Mr. Orlando said.
