Military macaws have burgundy tail feathers
Buffons have an orange-red look.
The green of a buffons is said to be lime green. However Google shows many buffons with darker green feathers. However the tail feathers are always 100% either burgandy(military) or red-orange(buffons).
The eye ring is not 100% safe way to tell. Diet and age affects eye ring coloration.
