I think Carolina Wrens can easily fit through a 1" hole, but will probably pick a site other than a nice nesting box for their nest. I have a nest of them right now in my garage. They come and go through a crack at the bottom of the garage door. The nest is in a box that has the lid cracked open just a bit. Once the babies are ready to go, I'll leave the garage door open a few inches so they can follow their mother out into the world. Carolina Wrens are creative nest builders. I have had them nest in nail aprons hanging on the wall and buckets. I have had them nest under the house, in the crawl space. They try to nest in my gas grill and lawn mower if allowed to. I have seen them checking out parked cars for possible nesting spots.

There are several little beaks bobbing and weaving in the nest. Mother and Father Phoebe are feeding them together. One of the parents--looked like Father Phoebe--served up a bug with its wings still on. Father Phoebe was working with the bug for some time. When he delivered it, the bug's body was facing towards Baby Phoebe. Baby Phoebe gulped it down with no complaints. Both parents stand together on the stamped concrete under the deck. They constantly scour the walls of the house for bugs. Now and then, they go up to the nest for a look-see. I haven't figured that out. Maybe looking for fecal sacs? Anyway, I can gawk all I want at this little family and they cannot see me.

Hi! A couple weeks ago we noticed 2 Carolina wrens building their nest in our fern right outside of our kitchen window. We were so excited! Then a few days ago we no longer saw them around and sadly thought that they had abandoned their nest. This morning we were talking about removing the nest from the fern and when I peeked, I saw 5 eggs! Now we are concerned if they have abandoned their eggs :( Is this possible? We haven't seen them around at all. What time of the day do they incubate? Would it be possible that we are missing their timing? We are not morning risers. Agh! I'd be so sad if by any chance we scared them away :( We have been very respectful, however sometimes we would open the window. I do not know how long the eggs have been there. I thought that as soon as they were close to being done building their nest, they had left. Do they first build and then lay their eggs? Thank you so much!

My daughter had a Carolina Wren nest (with eggs) in a precarious location. It was in a flower pot. We moved it a few feet every day until it was in a safe spot. The wren had no problem finding the nest each day, and continued to incubate the eggs. The result was a total success.
