There are birds around the world that use strands of different materials to craft marvelous woven nests that hang from tree branches — if you’re lucky enough to see them!

That’s right, the photo above isn’t of some weird fruit tree, but a tree-wide colony of oropendolas at Las Isletas, in Nicaragua!
