Upper mortality estimate is based on fly-out counts, lower number is based on day counts as available; **NA = not available; $Animals moved to new unknown camp (Lakeside) so searches were incomplete in 2006; $$No details about numbers of dead adult animals available, as too many juvenile animals were in care; numbers given were extrapolated from previous years.
