    Memory Connection Volume 1 Number 1 © 2011 The Memory Waka Nga¯ Tohu o nga¯ Kairaranga: The Signs of the Weavers Hokimate Pamela Harwood Memory Connection Volume 1 Number 1 © 2011 The Memory Waka Nga¯ Tohu o nga¯ Kairaranga: The Signs of the Weavers Hokimate Pamela Harwood Abstract The whakapapa (genealogy) and histories of iwi Ma¯ori (tribe/peoples) are continued within oral histories, and they are represented in our taonga (Ma¯ori treasures) such as toi whakairo (carving), ta¯ moko (tattoo), and whatu raranga (weaving). This article explores findings from the feather identification of Ma¯ori ka¯kahu (cloaks) in the Museum of New Zealand Te Papa Tongarewa. By examining the techniques and materials used in the making of selected cloaks, I reflect on how this information can potentially tell us about the weaver, the intended wearer, events, and the time and environment in which they were living. I argue that the discovery of possible feather “signatures” in ka¯kahu means that cloaks are a tangible form of retaining histories and memories. Finally, I propose that museums play an important role in unlocking and interpreting the knowledge needed to reconnect these taonga to their origins.

In birds, the most commonly occupy the same breeding and foraging habitats as observed interspecific feeding behaviour is of adults robins. feeding nestlings (Shy 1982). Previous observations I discovered a robin nest on 8 Jan 2010 in a have been opportunistic and brief because it is Hall’s totara (Podocarpus hallii). The female robin difficult to detect and monitor interspecific feeding, was regularly feeding nestlings, but the nest was particularly of cryptic fledglings.

  • Elwyn's Dream.Pages
    Elwyn’s Dream Teacher Notes by Raymond Huber Before Reading What is he holding on the cover? What do you know about the takahe? What do you think Elwyn’s dream is? What decade might this story be set? Introduction Note: You might like to read the introduction after reading the story because it explains the plot. Who ‘rediscovered’ the takahe? Why do you think Elwyn’s journey was a secret? Why would he take chickens with him? Try to define a ‘predator-free environment’. What does DOC stand for? Do you think it existed in the 1950s? Define ‘legislation’. Who makes these laws? What does a sponsor do? Why? Who sponsored this story (see back cover for answer). Comprehension Questions What do takahe eat? Why do you think there is only one takahe in the mountains shown in the first picture? Can takahe fly? Why did the three men let the bird go again? How many years ago was this? List three reasons for the fall in the population of takahe after its rediscovery. How might the deer and stoats have got to New Zealand? What kind of dream do you think Elwyn had: waking or sleeping? Look around Elwyn’s kitchen. List the things that are different to today’s household kitchen. What is a bantam? Why did Elwyn put hard-boiled eggs under the hen? Why did he take the bantams out on his tractor? What is a knapsack? Why must they stay on their nests ‘no matter what’? Why was Elwyn training the bantams with different eggs? Why did Elwyn and the men creep into the tussock? What does ‘iridescent’ mean? What other bird has iridescent feathers? Why must chicks always be kept warm? Do you think Elwyn should have tried to save the takahe in this way? Exploring the Illustrations * Medium: Look closely at the pictures.

    New Zealand 9th – 25th January 2020 (27 Days) Chatham Islands Extension 25th – 28th January 2020 (4 Days) Trip Report The Rare New Zealand Storm Petrel, Hauraki Gulf by Erik Forsyth Trip Report compiled by Tour Leader Erik Forsyth Trip Report – RBL New Zealand – Comprehensive I 2020 2 Tour Summary After a brief get together this morning, we headed to a nearby estuary to look for wading birds on the incoming tide. It worked out well for us as the tide was pushing in nicely and loads of Bart-tailed Godwits could be seen coming closer towards us. Scanning through the flock we could found many Red Knot as well as our target bird for this site, the endemic Wrybill. About 100 of the latter were noted and great scope looks were enjoyed. Other notable species included singletons of Double-banded and New Zealand Plovers as well as Paradise Shelduck all of which were endemics! After this good start, we headed North to the Muriwai Gannet Colony, arriving late morning. The breeding season was in full The Endangered Takahe, Tiritiri Matangi Island swing with many Australasian Gannets by Erik Forsyth feeding large chicks. Elegant White-fronted Terns were seen over-head and Silver and Kelp Gulls were feeding chicks as well. In the surrounding Flax Bushes, a few people saw the endemic Tui, a large nectar-feeding honeyeater as well as a Dunnock. From Muriwai, we drove to east stopping briefly for lunch at a roadside picnic area. Arriving at our hotel in the late afternoon, we had time to rest and prepare for our night walk.

  • Te Anau – Fiordland
    Community – Kea Project Plan Fiordland/Te Anau Funded by: Department of Conservation Community Fund (DOC CF) Period: 1 December 2015 – 31 October 2017. Key contact person: Kea Conservation Trust – Tamsin Orr-Walker – [email protected]; Ph 0274249594 Aim The aim of the Community – Kea Project Plan is to i) facilitate long-term community kea conservation initiatives and ii) to change the way we think, act and live with kea in our communities. This will be actioned through development of collaborative Project Plans across the South Island. Each community plan will address concerns specific to the local community and threats to the resident kea population. Project Background This initial project plan outline has been developed as a result of discussions with communities during the Kea Conservation Trust’s (KCT) Winter Advocacy Tour - 20 July – 3 August 2015. The tour was funded by Dulux and supported by Department of Conservation (DOC). The tour theme, “Building a future with kea”, aimed to promote a new MOU between communities and kea. This initiative is in line with the new Strategic Plan for Kea Conservation (refer attached draft document), objective 3: to i) increase positive perceptions of kea and reduce conflict and ii) facilitate formation of community led kea conservation initiatives. Local Community – Kea Project Plans will be activated by two Community Engagement Coordinator’s (CEC’s) based in the following areas: 1) Upper half of the South Island: Northern region (Nelson/ Motueka/ Kahurangi), Central North (Nelson Lakes/ Murchison/Arthur’s Pass/Christchurch/Mt Hutt) and upper West Coast (Greymouth and Hokitika). There is also the potential to include Kaikoura at a later date (the eastern most population of kea).

  • Released Under the Official Information Act
    From: To: Subject: RE: Traps great risk to kea: advocate | Otago Daily Times Online News Date: Tuesday, 9 May 2017 10:22:00 a.m. Thanks for that, Technically what is saying regarding the potential risk to kea is correct, although I cannot comment on the ‘scale’ of the risk. However, I'm concerned about what the article suggests DOC has said: 1. the captive trials showed that kea could actually access the trigger on an A24 2. as far as I am aware, DOC is not doing the kea monitoring or continual trap improvement as stated in the article. Furthermore, a kaka was killed by an A24 in Boundary Stream, this would indicate that a kea would be able to trigger the trap if it so desired. Cheers Principal Scientist - Threats Conservation leadership for our nature Tākinā te hi tiākinā te hā, o te āo tūroā -----Original Message----- From: Sent: Tuesday, 9 May 2017 9:53 a.m. To: nz> Subject: Traps great risk to kea advocate | Otago Daily Times Online News Hi Released Under The Have you seenOfficial this - https://www.odt.co.nz/regions/wanaka/traps-great-risk-kea-advocate Information Act ? Its possible, even likely that young kea will be attracted to the traps and large numbers of them might be killed. Kea are inquisitive by nature and young kea particularly so. Its not unlikely that all the young kea in these valleys will be killed each year. Until we are confident that only a very small number of kea will be killed in these traps, we can’t afford to use them at sites where kea will be at risk.
