Cedar Waxwings like a tree called "Service Berry." It is a multi-trunk tree and the berries are sweet. (The tree does shoot sucker shoots but I just clip them off). I have seen Waxwings between two 7-story buildings not more than 30 feet apart, feeding on these berries. I planted two of them and the following spring I had my first waxwings. They seem to travel in groups. I was thrilled. Looking for them again this year.
We have a very rocky soil. I don't really know what thrives best in this area and what not to attempt. I guess I will learn through a combination of research and experimentation.
