Coyote's Epic Swim to Alcatraz: Origin Shocks Experts
6 May
Summary
- Coyote swam from Angel Island, twice the suspected distance.
- DNA evidence confirmed the coyote's surprising origin.
- The animal's current whereabouts remain unknown.

A male coyote that recently swam to Alcatraz Island, a first since 1972, has surprised researchers with its true origin. Initially believed to have swum from San Francisco, DNA evidence now indicates the coyote originated from Angel Island, a significantly longer two-mile journey. Wildlife ecologist Bill Merkle expressed surprise, as the shorter San Francisco route was the working assumption.
This resilient and adaptable animal, nicknamed Floyd by some, embarked on an "epic swim" through the cold, choppy waters of San Francisco Bay. Researchers utilized camera traps and scat analysis, with lab results from UC Davis confirming the Angel Island population connection. The National Park Service noted three distinct coyote populations exist in the Bay Area.
Despite extensive monitoring, the coyote has not been seen since its initial sighting on Alcatraz and is no longer believed to be on the island. Its current whereabouts remain unknown, leaving its ultimate fate a mystery. Officials hope the animal successfully navigated its return journey.
