The Age of a Saw-whet Owl
is determined by examinating the wing for flight feathers of different ages.
The feather indicated by the white line is the oldest primary, and is so worn that it is broken at the tip.  The feathers with the most pink are the newest, formed after this year's breeding season.  We aged this owl as ASY, meaning that she is at least in her Third Year;  she hatched at least as early as 2009.
