This trick's called "Walking the Goat."
Those are mountain goats, and before you get too concerned, this isn't some kind of prank or terrifying new thing Amazon is working on. This is science. It's cool.
You see, when it's time to relocate animals across mountainous landscapes to friendlier, healthier habitats, a helicopter is the best option available. A truck would have to travel by winding, indirect roads, necessitating that the goat be sedated for longer than is healthy for them. But when transported by air, these goats evidently only need blindfolds and most of a canvas bag to be comfortable. In fact, goat relocation practically mandates a helicopter. After being transplanted, goats have been known to navigate hundreds of miles back to their original homes. So if you wanna lose a goat, you really have to huck that bastard way, way out there.
And they're not the only ones.
Below, an uncontacted tribe looks up and discovers their new god.
That's a black rhino, and it's a similar deal to the goats. When they used to transport the rhinos, they'd have to do it in trucks on bumpy roads, and the rhinos would have to be dangerously sedated to make it work. Helicopters had been used for moving rhinos in the past, but after some experimentation, they found that nets weren't really ideal because of the way they constricted the animal's breathing. Which is how we ended up with this setup: a blindfold, a truss, and a slap on the ass is all it takes for the world's most opulent pinata to take flight.
