We have a bird house full of baby house wrens, and they are the noisiest baby birds I have ever heard. As they have gotten bigger, their noise is nearly constant and is audible from all over the yard. I Googled “noisiest baby birds,” and house wrens were often listed. So it’s a thing.
There was one baby who clogged up the exit hole. His is the voice most often heard.
Does he look a little grumpy to you?
