In the post immediately above, I mentioned how Tucson garden writer and designer Scott Calhoun likes to use dried agave and desert spoon stalks for his native bee nesting sites.  And I love the naturalness of that approach, especially for casual gardens.

If your style is more formal, though, you might prefer the approach of his Tucson colleague, Greg Corman.  Landscape designer Corman designs nesting habitats that can double as sculpture.  They are constructed of pieces of wood rescued from salvage yards framed in steel.  (The steel is often recycled, too.)  Metal artist Tidhar Ozeri helps him construct the pieces.  There are more examples on Corman's website.
