I noticed in the Unique Birdhouse group, that "free Standing houses, Bat Houses, Duck, Goose and Swan Houses" including Pigeonniers are not allowed, and are denied.
I have ran across some very large and ornate Pigeonniers or DoveCotes. Pigeonniers are quite prevalent here. Seems different types of large bird houses are located in different parts of the world, for either food , down and fertilizer.
Even one listed on the National Register of Historic Places (http://www.waymarking.com/waymarks/WM5FDE_Barthel_Pigeonnier_Baton_Rouge_LA)
I was wondering if a Category for Waymarking these larger bird houses, such as Pigeonniers, Bat Houses, or Fowl houses would be of interest. I found that Bats houses can be quite different (http://www.floridabats.org/CBH_Articles/UF-BatHouse.htm) Maybe a Chicken Coup located at a Museum complex that has some sort of historic significance?
I was just thinking to "fill in a gap" that the unique Birdhouse group seems to have.
Maybe they can be put in already exsisting category... If so, please let me know.
