double hummingbird nest

Hello ,
First post here.
I'm a casual birder from my back yard and around town.
I have what seems to me to be a strange hummingbird nest. It's two nests seemingly made at the same time, and melded into one. Each one has two eggs, and is attended by a bird, however, I've never seen two birds there at the same time. There are birds that regularly sit on each pair of eggs, just not at the same time as far as I've seen. I'm not certain that there ARE two different birds.
This does not seem normal to me, but I'm certainly no expert. Can any one tell me how unusual this is?

Thank you,

Sounds very unusual. And, if there's only one bird incubating alternatively, I doubt that any of the eggs will hatch.
Known to follow bird waves.

Certainly not a normal occurrence!

A few species of birds, such as American Robins, have been known to build multiple adjacent nests on a flat surface, apparently due to confusion. However, the fact that two eggs are in EACH nest is interesting! I'd love to know if you ever see two adults at each nest simultaneously.

Here’s a double hummingbird nest of an entirely different kind—

We are keeping an eye on the nest as much as we can, but still have seen only one bird at a time. I'll let everyone know if two show up, and try to get pics.

Well, the hummer has deserted the nest. I guess she just couldn't keep both nests, 4 eggs, properly tended. I'm pretty sure there was only one bird on both nests.
We're sad to see this experiment end, but life goes on.
