Nest

Hello everyone.
Bird nests are quite interesting. You can see them on the trees or any building that is suitable. When I was kid it was amusing when I would come across some kind of nest. There were nests of pigeons, magpies, barn swallows and sparrows. Magpies would use some different materials in its nests. I think other birds use them as well. Some wires, ropes, plastic cables what ever it looks fitting for the nest.
Sometimes you wonder how they built it.
I think this should be nest of a magpie but I could be wrong.
Nest - black & white.
