They're also one of the few species to build roads and bridges.

I suspect the quiet part of the three assertions is "under human supervision".

You can certainly visit various zoos and purchase art by elephants and watch them paint with brushes on large canvases.

Typically less dense than a Jackson Pollack and less use of spaghetti than a Pro Hart* carpet.

Fun fact: Bison created deep, wide grooves in the plains and prairies that were subsequently used by the settlers moving west in their wagons.

Assuming that the videos are real, elephants on zoos had being recorded painting scenes on canvasses that aren't completely abstract. They are trained to paint to please visitors, but curiously they seem to enjoy drawing trees.

Is not clear to me if they just parrot the training or really try to send a message or draw some scene that they find instinctively pleasant. (but wouldn't be strange having in mind their intelligence).
