It seems to me that the foster-parent
system falls apart with the foster parents themselves, some of whom are very, very good, many of whom are abysmal, and a minority who are God-awful and should never be allowed near children.
In late December 2001, we placed orphaned-chick X into the nest of foster-parents A, and in early January 2002, we placed orphaned-chicks Y and Z into nests of foster-parents B and C, respectively.
Time between death of the chick of foster parents and start of adoption trials was 3 h for foster-parents A, 16 h for foster-parents B, and 15 min for foster-parents C.
Only one adoption was successful, as chick X was accepted and effectively provisioned and protected y foster-parents A until a tropical storm occurred in early April 2002 and almost all chicks on the island died, including chick X; the other two attempts failed (Ta le 1).
