I am really thankful this topic came up.
I was at the vet about a month ago for a parrotlet checkup and being that it is a clinic at a teaching hospital, the doc was talking things out for the four or five students with us in the examination room.
At one point she was commenting on how beautiful the bird's feathers are and pulled out her wing to show the students and said: "Look, absolutely no stress bars." I had no idea what a 'stress bar' is/was, though took it in as a 'good thing' and noted it for further investigation, which I promptly forgot.
What an interesting indicator of whatever. I may have to study this further... Is it like the inner rings of an old tree trunk, where you can determine certain eras where an otherwise healthy tree experienced a brief period of trauma, one which was 'grown past and forgotten' though stamped in its biological record?
