I have no idea who built this little home, but it's firmly attached to a branch of the horrible Autumn Olive.
The whole thing was only about 2.5 inches across. Seemed a bit large for a hummingbird, but definitely had to belong to a very small bird. I love how tightly it's woven into the foliage.
I carefully pulled the branch down to take a peek. The nest was empty, and judging from the hole in the far side, abandoned. The birds probably already hatched and fledged. I think it's adorable! I really need to get that field guide for bird's nests.
Maybe one of you real birder readers will know who lived here. I've added a closeup of the "cord" that holds the nest to the branch, in case that will help with the ID.
