the first mating in early February and
it was actually before Christmas.”
The conditions allowed the team
to double-clutch the birds: the
first clutch was taken for artificial
incubation, leaving females free to
lay a second clutch. For some nests,
transporting the eggs involved a
toughthree-hour night hike.
“There’s a huge weight of
responsibility. You can’t put aside the
thought that every life is completely
invaluable,” she explains. Upon
hatching, the team acted as
surrogate mothers until the
chicks could be returned to the
nest. It paid off. “We currently
have 70 surviving chicks from
this breeding season! It’s the
gest breeding season since
conservation efforts began.”
