Wrens in the garage

I noticed a wren several times entering the garage by hopping under the door and so I knew to look for a nest. I found it cunningly concealed so it couldn't be seen from the outside even with the garage doors open. It is an impressive construction particularly when you consider the size of the wren and the size of some of the bracken and other things used to build the nest and the fact they were presumably taken in under the door. Look closely and you can see an adult bird in the nest.
