Bird nest
There are several types of cup nests. A suspended cup nest is attached to the branch at the top and sides but then drops like a bag down below. It really looks more like a vase than a cup. The bird is almost hidden when she warms her eggs. The mother bird can sit down on the branch above the nest and bend down to feed her baby birds. Orioles are very famous for building amazingly long bags that hang far below the branch.
