Your habitat sounds like a great location for Purple Martins, especially since a neighbor is a Purple Martin landlord.

One of the reasons that you may not see birds at your site is the internal dimensions of the metal house nest cavities. One indicator would be if when you measure the nest cavity it is less that 6 inches by six inches as a minimum.

Our first house was a metal, Octagon, shaped house that the birds would look at but, not stay overnight nor nest. When we replaced the house with Purple Martin Association listed gourds we got results.

This is what we would try:

1. Measure the internal dimensions of a current individual nest cavity -- must be greater
   than 6x6in If the cavities are larger than 6x6 carefully read the attachments to see
   what could be the problem. Then continue to the recommendations below.
   
2. Visit the Purple Martin Association and consider purchasing three Super Gourds from their online store.
   
3. Hang these new gourds below the present housing
   
4. Put about a handful of dry pine needles inside the gourds
   
5. Consider purchasing a Purple Martin Decoy or two and put on top of the metal housing

You still have a about a month or so to attract Sub-adults - Purple Martins born last spring.

Check out a couple articles from the Purple Martin Association that may help.
