I love listening to bird calls and bird songs
I do too. We have a nest of morning doves and carolina wrens right outside our door. 
Yes the wren loves to live in dense forests and suburban areas
We live in Suburbia. Wrens have a beautiful song that they sing bright and early in the morning.
Yes wrens are small birds but they are loud and have some very complex songs
These wrens are not afraid of heights and their nest fits in our gutter.  They are very loud and make sure that you are awake.
Yes the most common wren is called a house wren - probably because they love people's houses!
