Rimutaka Forest Park Kiwi Produce a Viable Egg

January, 2007 - By Margaret Willard

An egg laid by Manaia, one of the eight kiwi released in Rimutaka Forest Park during 2006, has been found to be viable.

The egg has been taken to Mt Bruce Wildlife Reserve for incubation and hatching. If it hatches successfully, the chick will at some stage be returned to the forest park.

Volunteers using telemetry equipment to monitor the birds received a signal that Manaia’s mate Waikiwianui was incubating an egg in his burrow. They found two eggs in the burrow, one of which was rotten, but use of a candling technique showed the other to be viable.

Volunteer Annette Harvey says the chick was about 65 days old when examined. “We could see it moving inside. All going well, the chick should hatch within another two weeks.”

The egg is the first promising sign that the birds will reproduce, contributing to the goal of ten pairs of birds within ten years. Three more birds will be transferred to the park this year, making an adult population of ten, after the age-related death of Koniwi during November 2006.

“The egg’s arrival is a good sign for the future of the birds in the park,” says Annette Harvey. “That two are already breeding after eight months is encouraging, and we’re
excited about the possibility of a chick.”
