Answer
Red-eyed vireo
According to naturalist Bernd Heinrich, red-eyed vireos build their nests at any height but always in a deciduous tree. Their nests can be found in both forest and edge habitat. The nest is always a hanging cup suspended along its edges from a thin, horizontal, forked branch. It is a neat, tidy, compact structure that will have bits of birch bark, and usually also wasp paper, decorating the outside. The inside cup diameter of a vireo nest is 2 inches.
