By Andrew Penny – LEARNZ field trip teacher
During Conservation Week last month, the LEARNZ team ventured over to Franz Josef for another action-packed virtual field trip for 2011.
LEARNZ provides New Zealand registered teachers with unlimited free access to the largest contemporary collection of New Zealand online education material. LEARNZ specialises in virtual field trips, where students experience going right to the centre of the most fascinating events, businesses and locations around the country, in real-time. Participation is supported by online background materials and activities, and is enabled using live audioconferencing, web board, and diaries, images and videos uploaded daily.
Over 100 classes from all over the country joined me online to meet and talk with kiwi experts, as well as access a range of internet-based material related to BNZ Operation Nest Egg . We also met with members of Te Runanga o Makaawhio, kaitiaki/guardians of the population of rowi in Okarito.

There were a number of highlights on this field trip over the three days. One of these was our visit to the West Coast Wildlife Centre. The centre is the official home to the incubation and captive rearing programme for rowi and Haast tokoeka kiwi. Kiwi ranger Kim took us behind the scenes where the captive-reared eggs are processed after being brought in from Okarito forest. It was exciting to see the incubation room where they were currently incubating both rowi and Haast tokoeka eggs, with one just starting to hatch!

Also at the Wildlife Centre is a very cool nocturnal walk-through, where there are actual kiwi rummaging about in a naturalised habitat. It is the next best thing to stepping into a real forest and seeing these guys in action. One of the kiwi running around was Richter, the first rowi kiwi born after the September 2010 Christchurch Earthquake. Very cool indeed!
Another highlight was trekking into Okarito forest with rowi team leader Duncan Kay to check on a recently released juvenile rowi. It didn’t take long to find where its burrow was, but accessing it was another story!

The young kiwi was well hidden under a big old rata log, determined not to be woken up. Duncan couldn’t see where the burrow entrance was but eventually got hold of the sleepy kiwi through a narrow opening above. It was certainly an amazing experience and I felt very special because I got to hold one of the rarest kiwi in New Zealand while Duncan changed its transmitter.
On our last day Duncan took us back to the forest in search of a rowi kiwi egg that was ready to be lifted and taken to the West Coast Wildlife Centre for incubation. This particular egg was on the other side of Lake Mapourika, so Duncan took us across in the boat, the wind in our faces and incredible scenery all around us.

Once we got to the other side of the lake, Duncan got his aerial and radio receiver working. We trudged through thick native forest with the song of tui and sound of a kereru’s wing-beat high above us. The radio receiver was soon giving off loud beeps which meant the nest was not far away.
Duncan soon spotted the kiwi’s burrow. He pointed out a worn path leading to the entrance, and the remains of kiwi poo and a fallen feather were also key indicators that we were in the right spot. We were all very excited. I was holding the chilly bin that was filled with shredded paper to nurse the egg on its journey to the wildlife centre. There was also a hot water bottle inside to keep the egg warm, with a thermometer to ensure it did not get too hot.

The burrow was inside the base of a large tree. Duncan tried to get the egg through the burrow entrance but it was out of his reach. Several attempts were made to access the burrow from all around the base of the tree, but a massive tangle of roots and other climbing plants simply made it too difficult. In the end, the egg lift had to be abandoned.
I was gutted that we never got to see the egg and take it back to the West Coast Wildlife Centre. But Duncan wasn’t too worried at all. He said that the eggs are too big for stoats to get their mouths round so it would be safe until it hatches. And when it does hatch, the DOC team will head back to the burrow and remove the newly-hatched chick.
Although it was an unsuccessful egg lift, it was still great to get out into the forest and see part of BNZ Operation Nest Egg in action.

So all in all we had a fantastic three days on the LEARNZ Kiwi virtual field trip. We discovered a lot about how rowi kiwi are being saved from extinction and the great work being done through BNZ Operation Nest Egg. I certainly hope to head back soon and check up on this very special bird.
