a No eggs of wild origin were transferred to PWRC in 1972, 1973, and 1975 -1981.
Limited transfers were resumed in 1982 to increase the size and genetic diversity of the
captive flock. Transfers were increased in 1987 to build the captive flocks.
b Unhatched eggs are opened and examined.
c Includes one wet, newly- hatched chick which was removed from the nest (instead of the
other egg) to avoid chilling.
d Two eggs were infertile and sent only for examination; a third had an embryo that died in
incubation.
