A lone coyote that swam over a mile across the San Francisco Bay to Alcatraz Island is being monitored by scientists. The coyote, named Floyd, is currently thriving on the island and appears to be living off an avian diet. Experts say whether Floyd can stay on Alcatraz depends on his behavior, and there are concerns over local seabird populations. With no freshwater sources on the island, Floyd's survival might require human intervention. Captured video footage shows Floyd hopping onto the island's rocks after his swim, and his presence marks the first documented coyote sighting on Alcatraz since it became a national park in 1972. Visitors to the island can still access it as researchers observe Floyd's impact on the ecosystem and determine his needs for survival.
