Thanks everyone! My present thought is that I'll be mounting cages in the dinette area (table down and cushions removed). The cages can be easily removed. Wife already has other plans to mount cages, floor to ceiling, in the area across from the sofa where a small recliner is sitting (behind front passenger seat). This won't give the birds much window space though. We're even looking at removing the sofa and putting a single recliner there along with the bird cages.
Our macaw is a scarlet and usually is the center of attention wherever she is. Ha ha!
