Brown Bear enclosure at Salzburg Zoo

Do they not swim?

They do - but apparently they don't get out. I assume the water gets deep very quickly.

That looks very dangerous..!

It looks like a nice exhibit!

Yes , but i think bears like more forest. In zoos, al bears lives on mounitans, but they more like the forest. Why?

Why is it that so many glass barriers have bird drawings on them?

I thought it was to stop birds flying into them. I don't actually know but I was just assuming.
