San Francisco coyote swims to Alcatraz for first time ever

Park officials confirmed the first recorded coyote swimming to Alcatraz, likely driven by seasonal territory dispersal or accidental currents, witnessed and filmed by visitors.

  • Julian Espinoza confirmed that visitors and staff saw a coyote paddling to shore at Alcatraz Island's southern edge near the Agave Trail, a rare event for park biologists.
  • Moore speculated the coyote may have fallen in chasing prey and been swept by unusually strong currents estimated at eight or nine knots, while Christine Wilkinson suggested dispersal and January mating season could explain the crossing.
  • A tourist showed staff an iPhone recording and AirDropped it to Moore, who then radioed park rangers; they searched but could not locate the coyote after it arrived panting and shivering.
  • With nesting season underway, biologists warned the lone coyote could threaten eggs and chicks of western and California gulls, cormorants and snowy egrets on Alcatraz Island.
  • Researchers noted a coyote family recently established territory on Angel Island after swimming from the North Bay, while Wilkinson pointed to Interstate 280 and vehicle strikes as dispersal drivers.
