Did a little reading on house wrens.
They have a bad reputation for attacking other bird's nests even though they are little things.

They also build dummy nests.
This may be what we are seeing here?

Are dummy nests to make predators think they live there and to not go to their real nest?

I guess it is a decoy.
It might keep other birds from building there too.
But I think the males might build several nests and try to get the female interested to pick one of them.

If its a decoy and no birds will move in since they think its taken, then move the decoy somewhere else, so we can have some more residents in the WEO bird house Hotel. Any takers?

EDIT: Why was Coolgal's comment deleted? Shocked

I have decided that this is for sure a dummy nest.
See the white things in the nest?
Those are cocoons placed there by the male.
Here is an explanation of what is known about that.


Males in the cavity-nesting house wren (Troglodytes aedon) frequently add arthropod cocoons to their nests during building, possibly as an ornamental cue for female choice. We tested this hypothesis by comparing the time to pairing for males that did and did not add cocoons to their nests and for males in whose nests we manipulated the number of cocoons prior to pairing. We also tested the hypothesis that females acquire fitness-related benefits by selecting mates based on their use of cocoons. The use of cocoons by males was not consistently related to habitat, but the number of cocoons added per nest increased during the course of the breeding season. Contrary to prediction, the time to pairing for males adding cocoons was significantly longer than that for males without cocoons in their nests at both unmanipulated and experimental nests. There was also no consistent fitness-related benefit for females related to the use of cocoons by their mates. Therefore, we conclude that females did not prefer males that added cocoons to their nests, and that the increased time to pairing for males that add cocoons likely results in fitness-related costs brought about by delayed breeding. Nonetheless, male house wrens routinely use cocoons, and why they do so remains unknown.

They must find the cocoons and bring them in.
I don't think birds make cocoons.

We talked about the dummy nest.
Well here was the real nest in a bird house with no camera.
It just got attacked by a snake, and here is the whole story.
