The Wrybill <I>Anarhynchus Frontalis</I>: a Brief Review of Status, Threats and Work in Progress
The Wrybill Anarhynchus frontalis: a brief review of status, threats and work in progress ADRIAN C. RIEGEN '1 & JOHN E. DOWDING 2 •231 ForestHill Road, Waiatarua, Auckland 8, NewZealand, e-maih riegen @xtra.co. nz; 2p.o. BOX36-274, Merivale, Christchurch 8030, New Zealand, e-maih [email protected]. nz Riegen,A.C. & Dowding, J.E. 2003. The Wrybill Anarhynchusfrontalis:a brief review of status,threats and work in progress.Wader Study Group Bull. 100: 20-24. The Wrybill is a threatenedplover endemic to New Zealandand unique in havinga bill curvedto the right.It is specializedfor breedingon bareshingle in thebraided riverbeds of Canterburyand Otago in the SouthIsland. After breeding,almost the entirepopulation migrates north and wintersin the harboursaround Auckland. The speciesis classifiedas Vulnerable. Based on countsof winteringflocks, the population currently appears to number4,500-5,000 individuals.However, countingproblems mean that trendsare difficult to determine. The mainthreats to theWrybill arebelieved to be predationon thebreeding grounds, degradation of breeding habitat,and floodingof nests.In a recentstudy in the MackenzieBasin, predation by introducedmammals (mainly stoats,cats and possibly ferrets) had a substantialimpact on Wrybill survivaland productivity. Prey- switchingby predatorsfollowing the introductionof rabbithaemorrhagic disease in 1997 probablyincreased predationrates on breedingwaders. A recentstudy of stoatsin the TasmanRiver showedthat 11% of stoat densexamined contained Wrybill remains.Breeding habitat is beinglost in somerivers and degraded in oth- ers,mainly by waterabstraction and flow manipulation,invasion of weeds,and human recreational use. Flood- ing causessome loss of nestsbut is alsobeneficial, keeping nesting areas weed-free. The breedingrange of the speciesappears to be contractingand fragmenting, with the bulk of the popula- tion now breedingin three large catchments. -
New Zealand Comprehensive II Trip Report 31St October to 16Th November 2016 (17 Days)
New Zealand Comprehensive II Trip Report 31st October to 16th November 2016 (17 days) The Critically Endangered South Island Takahe by Erik Forsyth Trip report compiled by Tour Leader: Erik Forsyth RBL New Zealand – Comprehensive II Trip Report 2016 2 Tour Summary New Zealand is a must for the serious seabird enthusiast. Not only will you see a variety of albatross, petrels and shearwaters, there are multiple- chances of getting out on the high seas and finding something unusual. Seabirds dominate this tour and views of most birds are alongside the boat. There are also several land birds which are unique to these islands: kiwis - terrestrial nocturnal inhabitants, the huge swamp hen-like Takahe - prehistoric in its looks and movements, and wattlebirds, the saddlebacks and Kokako - poor flyers with short wings Salvin’s Albatross by Erik Forsyth which bound along the branches and on the ground. On this tour we had so many highlights, including close encounters with North Island, South Island and Little Spotted Kiwi, Wandering, Northern and Southern Royal, Black-browed, Shy, Salvin’s and Chatham Albatrosses, Mottled and Black Petrels, Buller’s and Hutton’s Shearwater and South Island Takahe, North Island Kokako, the tiny Rifleman and the very cute New Zealand (South Island wren) Rockwren. With a few members of the group already at the hotel (the afternoon before the tour started), we jumped into our van and drove to the nearby Puketutu Island. Here we had a good introduction to New Zealand birding. Arriving at a bay, the canals were teeming with Black Swans, Australasian Shovelers, Mallard and several White-faced Herons. -

SOUTH ISLAND SADDLEBACK RECOVERY PLAN (Philesturnus Carunculatus Carunculatus )
THREATENED SPECIES RECOVERY PLAN SERIES NO.11 SOUTH ISLAND SADDLEBACK RECOVERY PLAN (Philesturnus carunculatus carunculatus ) Prepared by Andy Roberts (Southland Conservancy) for the Threatened Species Unit Threatened Species Unit Department of Conservation P.O. Box 10-420 Wellington New Zealand © 1994 ISSN 1170-3806 ISBN 0-478-01481-9 Key words: South Island saddleback, Philesturnus carunculatus carunculatus, recovery plan ABSTRACT South Island saddlebacks (tieke) were widely distributed over the South and Stewart Islands in the 19th century. Their rapid decline was documented during the latter 19th century. Following a rodent invasion on their sole remaining island habitat South Island saddlebacks were under threat of immediate extinction. This was thwarted by prompt translocations of remaining birds to nearby predator-free islands. This plan outlines conservation goals and suggests options for continuing the recovery of this subspecies. Recovery is to be achieved through a programme of island habitat restoration and saddleback translocations. Eradication of rodents and weka is promoted by this plan, in some instances this plan suggests that discussions be held with the local Iwi to determine the appropriateness of these eradications. Saddlebacks are to be introduced or re-introduced to a number of islands around the South Island coast. When recovery has been achieved South Island saddleback populations may be established on up to 26 islands with a total of about 4000 individuals. At this population level they will not be ranked as threatened, but be classified as rare and no longer requiring a programme of on-going intensive conservation management. Recovery management proposed in this plan will be undertaken jointly by Department of Conservation staff, Iwi representatives and members of the public. -
Birds Suborder PASSERES (Or POLYMYODI): Oscines
Text extracted from Gill B.J.; Bell, B.D.; Chambers, G.K.; Medway, D.G.; Palma, R.L.; Scofield, R.P.; Tennyson, A.J.D.; Worthy, T.H. 2010. Checklist of the birds of New Zealand, Norfolk and Macquarie Islands, and the Ross Dependency, Antarctica. 4th edition. Wellington, Te Papa Press and Ornithological Society of New Zealand. Pages 275, 279 & 301-305. Order PASSERIFORMES: Passerine (Perching) Birds See Christidis & Boles (2008) for a review of recent studies relevant to the higher-level systematics of the passerine birds. Suborder PASSERES (or POLYMYODI): Oscines (Songbirds) The arrangement of songbirds in the 1970 Checklist (Checklist Committee 1970) was based on the premise that the species endemic to the Australasian region were derived directly from Eurasian groups and belonged in Old World families (e.g. Gerygone and Petroica in Muscicapidae). The 1990 Checklist (Checklist Committee 1990) followed the Australian lead in allocating various native songbirds to their own Australasian families (e.g. Gerygone to Acanthizidae, and Petroica to Eopsaltriidae), but the sequence was still based largely on the old Peters-Mayr arrangement. Since the late 1980s, when the 1990 Checklist was finalised, evidence from molecular biology, especially DNA studies, has shown that most of the Australian and New Zealand endemic songbirds are the product of a major Australasian radiation parallel to the radiation of songbirds in Eurasia and elsewhere. Many superficial morphological and ecological similarities between Australasian and Eurasian songbirds are the result of convergent evolution. Sibley & Ahlquist (1985, 1990) and Sibley et al. (1988) recognised a division of the songbirds into two groups which were called Corvida and Passerida (Sibley & Ahlquist 1990). -

The Impact of Predation by Introduced Mammals on Endemic Shorebirds in New Zealand: a Conservation Perspective
Biological Conservation 99 (2001) 47±64 www.elsevier.com/locate/biocon The impact of predation by introduced mammals on endemic shorebirds in New Zealand: a conservation perspective John E. Dowding a,*, Elaine C. Murphy b aPO Box 36-274, Merivale, Christchurch 8030, New Zealand bScience and Research Unit, Department of Conservation, Private Bag 4715, Christchurch, New Zealand Abstract The avifauna of New Zealand has been severely depleted since human colonisation and currently contains a disproportionately high number of threatened species. Of the 23 threatened shorebird species worldwide, six are endemic to New Zealand. We review the status of New Zealand's endemic shorebirds and examine the impact on them of various threats, particularly predation by introduced mammals. The conservation status of the 10 extant species (three oystercatchers, one stilt, four plovers and two snipe) is outlined and the factors that predisposed them to predation by introduced mammals are summarised. Individual species accounts are presented, including data on population trends, known or suspected impacts of predation, identi®cation of important predator species, other threats, and conservation measures currently in place or required. One species and two subspecies are extinct, three species are con®ned to predator-free islands and another is found only on the Chatham Islands group. Six survive on the mainland but three have declined to varying degrees and are assigned threatened status by Collar et al. (1994). Only one plover and two oystercatchers are still relatively numerous and/or widespread. Rats, cats and mustelids have had the greatest overall impacts. Conservation measures in place to mitigate the eects of introduced predators include the formulation of recovery plans, predator control around breeding areas, captive breeding and rearing programmes and the founding of new populations by translocation. -

Predation As a Primary Limiting Factor: a Comparison of the Effects of Three Predator Control Regimes on South Island Robins (Petroica Australis) in Dunedin, NZ
Predation as a primary limiting factor: A comparison of the effects of three predator control regimes on South Island robins (Petroica australis) in Dunedin, NZ. A thesis submitted for the degree of Master of Science at the University of Otago, Dunedin, New Zealand Michael Alexander Terence Jones 10/02/2016 1 ACKNOWLEDGEMENTS I would like to thank Ian Jamieson for his tireless efforts as my supervisor, mentor and friend. He provided me with an opportunity to work in some of the most remarkable places in New Zealand with some of its most treasured species. He also enabled me to contribute to the field of zoology, one I have been passionate about since as early as I can remember. Without Ian’s support and guidance none of this could have been achieved. I would also like to thank Yolanda van Heezik and Phil Seddon for their willingness to take me and the robin project on after Ian’s passing. They have worked tirelessly to help me mould my thoughts and writing into a legible thesis and I will be forever grateful for their help. This research would not have been achievable without the dedication and hard work of all the field workers and volunteers over the years. I would like to thank Leon ‘Leroy Bernard’ Berard, Jamie Cooper, Fiona Gordon, Tracy Dearlove, Rebecca McMillan and Luke Easton for all the long hours they spent watching countless robins. A special thanks to Sam Ray for organising everything and making sure all the equipment was available and booked and putting up with Leon and myself over the long summer period. -
Translocations of North Island Tomtits (Petroica Macrocephala Toitoi) and North Island Robins (P

Translocations of North Island tomtits (Petroica macrocephala toitoi) and North Island robins (P. longipes) to Zealandia-Karori Sanctuary, an urban sanctuary. What have we learned? RAEWYN EMPSON* Karori Sanctuary Trust, P.O. Box 9267, Wellington 6141, New Zealand DENISE FASTIER Department of Conservation, P.O. Box 644, Napier 4140, New Zealand Abstract Transfers of North Island robin (Petroica longipes) and North Island tomtit (P. macrocephala toitoi) were undertaken from various sites around the Wellington region to within the mammal-proof fence at the Zealandia-Karori Sanctuary from 2001-2004. Differing methodologies were trialled to test translocation protocols for these species. Robin translocations (34 males and 42 females from Kapiti I translocated in 2000 and 2001) were straightforward and robins established in the sanctuary despite the fence not being a physical barrier to dispersal. They bred from the first season and numbers have since increased rapidly. Tomtits were transferred from 2 source populations (Kapiti I and Akatarawas; 39 males and 12 females over 4 years from 2001-2004) but failed to establish. To hold tomtits in an aviary and avoid aggression it was necessary to keep sexes apart. Although successful tomtit breeding was observed both within and outside the sanctuary, predation pressure was higher outside the sanctuary. A progressive move of tomtit territories out of the sanctuary may have been a response to increasing aggression from the expanding robin population. Empson, R.; Fastier, D. 2013.
