  1. Regarding dating methods by using SSN: The SSN is not assigned in order of birth. The pre-fixes are regional. There’s a more complete explanation here: http://en.wikipedia.org/wiki/Social_Security_number

    I had a friend who claimed his grandma was so old her SSN was 000-00-0003, but that didn’t sound right to me, so I checked it out. My grandparents were older, and their SSN’s each stared with “47” like mine, so what he said didn’t make sense.

  2. There are many more methods than these, most involving assessing the molt. Some birds can be aged to 3 or more years using molt limits.
