I have a narrow area between two raised beds where I need to fill in a tall garden detail. I am wondering if someone makes bird homes on a tall pole or that could easily be mounted on a fence post that goes up maybe 12 feet to 20 feet high? I would like something that looks very nice and will remain intact for 10+ years. What are my options?

I am near San Jose, California in a Mediterranean climate. I would be sure to place the homes in a spot that gets morning sun and afternoon shade.
