This sort of thing is a huge problem here in New Zealand. The only native mammal here is a bat, we have mostly birds which evolved for a really long time with only avian predators. So they’re hilariously poorly adapted for surviving standard predators (cats, rats, dogs etc) which first the Maori and subsequently Europeans brought. For example, many of them are flightless and tend to freeze when threatened - works well against eagles but is a terrible idea when threatened by a cat.

As a result, we have many animals, mostly birds, which are totally unique and also critically endangered. Many of them can only survive on offshore islands which have been comprehensively cleared of predators at vast effort and expense. The islands need to be relatively accessible since humans have to get to them to maintain them, but it turns out that once in a while a predator will swim quite vast distances for no apparent reason, and it only takes one to mess up years of painstaking work. Quite apart from killing a bunch of birds whose total remaining numbers might range from the tens to the hundreds of individuals.

It's a 1.5mi swim.

I remember visiting Angel Island (a 0.5mi swim) and seeing the abundance of raccoons they have, and asked a ranger how they got there. They also swam.

Growing up on a lake I would regularly watch deer swim the quarter mile back and forth between the shore and a nearby island, with no problem.

If you time things right, and don't get swept out to sea, it's the 54 degree water that is the real danger. I'm no medical person, but it sure seems like that the animal is suffering from hypothermia and fatigue. I'm sure it'll have happy hunting once it recovers.

I would be surprised if the Coyote would be quick to get back into the water after such a difficult swim. It would, I suspect, want to recover and find food. So I support the theory the Coyote is just hiding somewhere. The island is small but not that small that it couldn’t hide somewhere.

I didn't think anti-bot stuff could get more annoying but to sit there and hold a button for like 20 seconds straight with nothing else on the screen to look at is incredibly boring and annoying and I gave up and left the page 3/4 of the way through it.

Poor thing, talk about going in the wrong direction :)

Impressive though.

I wonder if a turtle drowned halfway across.

That roadrunner thought he'd be safe hiding out on the notorious prison island...

aw poor baby

I really like the coyotes here.

Only dumbass mfs who let their pets off leash (I live in Pac Heights, you're supposed to have a leash on your dog at Lafayette Park and yet every day I see morons letting their dogs off leash OUTSIDE THE DAMN DOG PARK AREA. FUCK OFF!!!!) or let their small children go without supervision where they're not supposed to are at risk.

The worst part is that the authorities will put down the coyote (for being a coyote) and I hate reading stories about coyote culling.

Life would be so much better if morons were fined and eventually displaced into oblivion for making dumbass decisions that could have been easily avoided if they were not so negligent.

But yeah its nice to live in a city with cool nature like that. We have parrots, raccoons (there's a little family of them living near my home), coyotes, owls, hawks. Love it!

The article speculates that this coyote might attempt to establish a pack on Alcatraz, by calling until a mate makes the same 1.5 mile swim in treacherous cold water.

I wish everyone the best of luck here, but I can't shake the image of the lonely guy unwittingly calling young females in proestrus to their likely deaths. An appropriately gender-swapped Coyote Siren of Alcatraz.

Maybe female coyotes are smart enough to understand SF Bay tides and currents, or just to ignore the crazy loud guy. I sure hope so.

If a Coyote could do it, all those famous escapees must have had too.
