I'm thinking I lost the bottoms to 16 bird houses (8 of each) and am needing to cut them again. How much room will the birds need to perch on if I make new ones that fold down this time rather than the plug ones?

  • Do you mean how big should a nesting box be ? The standard pattern I have ( for either ) has a 4 X 4" bottom. The location of nest boxes is more important than size. I have Carolina wrens ( little larger than house wren) and they nest anywhere , like in car bumpers. Commented Apr 3, 2021 at 20:01
  • the ledge inside the box itself so that a nest has something to sit on
