Unbelievable Journey: Coyote Swims to Alcatraz – Discover the Impressive Distance Covered!

An unexpected guest surprised visitors at Alcatraz Island earlier this year: a lone coyote, whose presence sparked both curiosity and intrigue. This uninvited visitor didn’t just make a splash by swimming to the infamous former prison island; it likely undertook a far more challenging aquatic journey than initially imagined.

The coyote was first sighted on January 24, its sudden appearance captured by a visitor’s video, which prompted a quick response from National Park Service staff. This surprising encounter sent biologists scrambling to investigate, as they discovered fresh tracks and scat, and promptly set up cameras and audio equipment in hopes of tracking the elusive animal.

Despite the promising early signs, the coyote vanished as quickly as it had appeared. Though evidence of its presence was abundant in the initial days, and experts kept a vigilant watch for months afterward, the coyote remained hidden, leaving behind only questions and speculation.

The mystery deepened with the coyote’s sudden disappearance, adding another layer to the enigmatic tale of its daring adventure to and from the shores of Alcatraz.

What happened next only deepened the mystery.

Scientists analyzed DNA from the scat at the UC Davis Mammalian Ecology and Conservation Unit (MECU) to trace the animal’s origin. 

Initially, experts thought the coyote had crossed the bay from San Francisco, a challenging swim on its own.

The lab results told a different story.

“Three distinct coyote populations could have been the source of the Alcatraz coyote: San Francisco, Southern Marin, and Angel Island,” Dr. Ben Sacks of MECU told KRON.

“Our lab was able to take the DNA sample and match it to a coyote previously sampled from the Angel Island population.”

That finding means the animal likely swam from Angel Island, roughly two miles north of Alcatraz, doubling the originally assumed distance across the cold, choppy waters of San Francisco Bay.

Wildlife ecologist Bill Merkle said the feat points to the species’ toughness.

“Coyotes are known to be resilient and adaptable, and he certainly demonstrated those qualities,” he told KRON.

Yet for all its grit, the coyote’s fate remains completely unknown.

There have been no further sightings, no camera captures and no remains discovered anywhere on the island.

“We don’t know what happened to the coyote,” Merkle said. “But he proved himself an expert swimmer to get to Alcatraz, and I hope he made a successful swim back home to Angel Island.”

Alcatraz, once a high-security federal prison that operated from the 1930s until its closure in the 1960s due to high costs, has long been known for failed escape attempts, with most inmates unable to survive the bay’s icy, fast-moving currents.

The island reopened as a public park in 1973.
