Very few museum specimens of the Chatham Island taiko exist. The type specimen (called the magenta petrel) is held in the Turin Regional Natural Science Museum in Italy, having been collected in the south-eastern pactifc by His Italian Majesty's ship Magenta on July 22, 1867. No other taiko specimens are known to be held by any other overseas museum and Te Papa Tongarewa Museum of New Zealand holds one adult study skin and one mounted juvenile.
Recently Paul Scofield of Canterbury Museum discovered what appeared to be a mounted taiko specimen in the Canterbury Museum collection, however it was labelled as a Tahiti petrel. The only information on the origin of the specimen is that it was collected in the Pacific Ocean and has been in the Canterbury Museum collection since at least 1910.
Hayley Lawrence of Massey University was able to compare the DNA of this bird to the original magenta petrel with blood samples taken from Chatham Island taiko and confirm that they were all of the same species.

A common woodland lichen of eastern Australia that has been recorded only twice from
New Zealand in 1934 and
1976, and then only from the far north of the North
Island has turned up on the Chatham Islands. The lichen, Heterodea muelleri is a leafy species that in Australia grows in moderately open
woodland habitats. In New Zealand,
until it was recognised from the Chatham Islands it had only ever been recorded
from dune slacks somewhere on the Ninety
Mile Beach
and from damp sandstone ridges in light scrub near Puheke, Karikari Peninsula.
The Chatham
gatherings came from the north-western end of Ocean
Bay, Chatham
Island and from the top of Hakepa Hill
(Walkemup), Pitt Island. At Ocean Bay
the lichen grew on sandy peat and clay above schist on the margin of salt and
wind blasted vegetation. In this habitat it was associated with the lichens Cladia aggregata and C. retipora, and sedge Lepidosperma australe. On Hakepa Hill
specimens were gathered from amongst the dense drifts of Cladonia lichens that grow between the low, windswept fernland that
covers most of that trachyte peaks summit.

The Chatham Island tui translocated by the Taiko Trust from Rangatira Island to the Awatotara Manuel and Evelyn Tuanui Family Covenant in March are doing well. All 14 birds are still visiting the feeders, and an unbanded bird, first seen during DOCs parea survey, has also joined the group.
Liz Tuanui reported today that the first signs of breeding have been spotted with one banded bird seen collecting dry grass. Bruce Tuanui was able to follow the bird to its nest in a hoho tree.
Banded tui have been seen in several gardens on the South coast - Ollie Seymour was particularly delighted to see them feeding on karo flowers in her garden as she has not seen them since she was a girl at Te Awatea 60 years ago. |

The team of Department of Conservation and Taiko Trust team running spotlights in the Tuku valley have been successful in catching three unbanded taiko in one night. All three birds had radio transmitters attached and it is hoped that the birds can be tracked back to a burrow which can be then managed in order to protect the nest from predators and increase the world population of taiko from just 15 breeding pairs.
Update: as of Oct 27th 13 birds have been caught, 7 of which were unbanded. Well done team!
