In exception, in cases where captures are the only recorded event prior to a known acquisition date, the capture date is assigned as 1 January or 15 July of the six month period preceeding acquisition. Although this convention may indicate an inordinate amount of time between wild hatch and capture, it minimizes the presumption of undocumented time in captivity. An additional related convention used here is the assignment of wild hatch and capture dates to the one year period preceeding a dated event not preceeded by any other event when no estimations for originating events have been provided. As many of the studbook vultures have unknown or rough accounts regarding their origination, these conventions give the studbook population minimal age and longevity approximations. Requests for electronic copies should be made to the studbook keeper.
