One bird seemed to have a bit more 'bird brain' than the others and would sometimes circle around the tyre looking for the intruders but then would return and attack the Striated Fieldwren © Kevin Williams hubcap even more crossly. We stood and watched for a long time and then left them to it. It was a delightful interlude that left us with grins on our faces. CONTENTS: Happy Birding 2. Outing report & bird list Susan 3.

They call it palaeontologists from Flinders and several other "Squawkzilla". universities have been working the area for the past 20 years. It is, scientists announced on Wednesday, the largest parrot ever discovered. Squawkzilla’s bones were found while the team were digging into mudstone in the side of a hill. A volunteer took dirt and mud from the dig down to a stream and washed it in a sieve. The cold waters washed the dirt away – leaving behind two enormous leg bones, broken into five pieces. Initially, Professor Worthy thought they were probably eagle bones, so they were placed in a drawer and ignored. But later, when he got them back out and inspected them, he realised that wasn’t quite right. Bones have specific marks where the muscles and ligaments are attached. These bones did not have the right attachment marks for an eagle.

  • The Birds Of
    Haast’sThe Eagle Birds of Moa The Haast’s eagle was the largest eagle to have ever existed, weighing up to 230 kg (510 lbs)! It became extinct in the 1400’s after its primary food source, the moa, was hunted to extinction. Kākāpō Early inhabitants hunted the kākāpō for its plumage and meat. European settlers cleared their land, and newly-introduced predators such as cats, rats and stoats hunted them to near extinction. There are fewer than 160 known surviving kākāpō! Kea Kea are the world’s only alpine parrot. They nest in holes in the ground which makes them easy prey for rodents introduced to New Zealand such as stoats, rats, and possums. They are endangered in New Zealand, with fewer than 7,000 left. Kiwi There are fewer than 68,000 kiwis left, and about 2% of unmanaged kiwi are lost every year. Rodents introduced to New Zealand share the same food sources; this appears to stunt the growth of kiwi chicks. Moa New Zealand was home to nine different species of moa, a flightless bird reaching 3.6m (12 ft) in height. They became hunted to extinction by around the year 1400, but are a prime candidate for cloning due to the amount of moa remains in exis- tence. Morepork The morepork is known for its haunting, melancholy song in the night. It is New Zealand’s only surviving native owl. The morepork belong to the spirit world and are watchful guardians in Māori tradition. Pūkeko Pūkeko average 51cm long (20 in). They’re found in marshy or open country.

  • Grounded Birds in New Zealand
    Flightless Grounded Birds in New Zealand An 8th Grade Research Paper By Nathaniel Roth Hilltown Cooperative Charter Public School June 2014 1 More than half of the birds in New Zealand either can’t fly, can only partially fly, or don’t like to fly. (Te Ara) This is a fact. Although only sixteen species in New Zealand are technically flightless, with another sixteen that are extinct (TerraNature), a majority of more than 170 bird species will not fly unless their lives are threatened, or not even then. This is surprising, since birds are usually known for flying. A flightless bird is a bird that cannot fly, such as the well­known ostrich and emu, not to mention penguins. The two main islands southeast of Australia that make up New Zealand have an unusually diverse population of these birds. I am personally very interested in New Zealand and know a lot about it because my mother was born there, and I still have family there. I was very intrigued by these birds in particular, and how different they are from most of the world’s birds. I asked myself, why New Zealand? What made this tiny little country have so many birds that can’t fly, while in the rest of the world, hardly any live in one place? My research has informed me that the population and diversity of flightless birds here is so large because it has been isolated for so long from other land masses. Almost no mammals, and no land predators, lived there in the millions of years after it split from the Australian continent, so flying birds didn’t have as much of an advantage during this time.

It suggests that nostalgia for the Huia specifically, and New Zealand's indigenous birds more generally, has occurred as both restorative nostalgia and reflective nostalgia. It argues that the former problematically looks to recreate a past world in which birds flourished. In contrast, the paintings of Bill Hammond and the sound art of Sally Ann McIntyre are drawn on to explore the potential of reflective nostalgia for remembering the Huia, and New Zealand's extinct indigenous birds more generally, in a more critical and nuanced way.

  • Meet the 'Hercules Parrot' from Prehistoric New Zealand – the Biggest Ever Discovered
    17/06/2020 Meet the 'Hercules parrot' from prehistoric New Zealand – the biggest ever discovered Support accurate, fact-based coverage on COVID-19. Donate Academic rigour, journalistic flair Meet the ‘Hercules parrot’ from prehistoric New Zealand – the biggest ever discovered August 7, 2019 9.13am AEST Author Trevor H. Worthy Associate professor, Flinders University Heracles inexpectatus on the forest floor, with three small wrens foraging at its feet. Brian Choo, Author provided Say hello to Heracles inexpectatus, a parrot the size of a human child. But don’t worry, you won’t meet one face to face. Our new discovery, published today, lived around 20 million years ago in what is now New Zealand – adding to the islands’ rich and storied collection of remarkable bird species. Heracles was truly a giant among birds. It was about 1m long, stood 80-90cm tall, and weighed about 7kg. That makes it about the same size as a dodo, and far bigger than its modern-day cousin, the kākāpō. Unsurprisingly, given its heft, it was likely also flightless. https://theconversation.com/meet-the-hercules-parrot-from-prehistoric-new-zealand-the-biggest-ever-discovered-121437 1/3 17/06/2020 Meet the 'Hercules parrot' from prehistoric New Zealand – the biggest ever discovered Read more: Tall turkeys and nuggety chickens: large 'megapode' birds once lived across Australia Islands are renowned for huge birds, perhaps none more so than New Zealand. Its fame in this regard began in 1839, when the English scientist Richard Owen first revealed the giant moa to the scientific world. In the next few years, many species of moa were named; now there are nine species in six genera, making them the world’s largest grouping of flightless birds.

  • An Extremely Low-Density Human Population Exterminated New Zealand Moa
    ARTICLE Received 15 Apr 2014 | Accepted 1 Oct 2014 | Published 7 Nov 2014 DOI: 10.1038/ncomms6436 An extremely low-density human population exterminated New Zealand moa Richard N. Holdaway1,2, Morten E. Allentoft2,3, Christopher Jacomb4, Charlotte L. Oskam5, Nancy R. Beavan6 & Michael Bunce7 New Zealand moa (Aves: Dinornithiformes) are the only late Quaternary megafauna whose extinction was clearly caused by humans. New Zealand offers the best opportunity to estimate the number of people involved in a megafaunal extinction event because, uniquely, both the Polynesian settlement of New Zealand and moa extinction are recent enough to be dated with a high degree of precision. In addition, the founding human population can be estimated from genetic evidence. Here we show that the Polynesian population of New Zealand would not have exceeded 2,000 individuals before extinction of moa populations in the habitable areas of the eastern South Island. During a brief (o150 years) period and at population densities that never exceeded B0.01 km À 2, Polynesians exterminated viable populations of moa by hunting and removal of habitat. High human population densities are not required in models of megafaunal extinction. 1 Palaecol Research Ltd, PO Box 16569, Christchurch 8042, New Zealand. 2 School of Biological Sciences, University of Canterbury, Christchurch 8140, New Zealand. 3 Centre for Geogenetics, Natural History Museum, University of Copenhagen, Copenhagen DK-1350, Denmark. 4 Southern Pacific Archaeological Research, Department of Anthropology and Archaeology, University of Otago, PO Box 56, Dunedin 9054, New Zealand. 5 School of Veterinary and Life Sciences, Murdoch University, Perth, Western Australia 6150, Australia.

  • Alex Boast, Phd Candidate, School of Environment, University of Auckland
    Alex Boast, PhD candidate, School of Environment, University of Auckland It may be surprising to think that kakapo were once one of the most common and widespread birds in New Zealand. It was just over a Century ago, that the explorer Charlie Douglas wrote that kakapo were so common in some remote forests that they could be shaken out of tutu bushes “like apples”. NZ’s rich fossil record shows that kakapo probably occurred in all the forested habitats on the NZ mainland, whether it be subtropical kauri forest, rainy mountain beech forest, or dry Central Otago woodlands. Furthermore, in some fossil‐rich cave regions, such as Waitomo, kakapo remains dominate above other bird species. These plump, flightless, nocturnal parrots must have once had an important impact on NZ’s ecosystems, and males must have filled the forests with their lusty booming calls during the Summer. They evidently also had the potential to live in a much broader variety of habitats than the tiny surviving populations occupy today. Any information how kakapo may have once lived in different habitats in ancient NZ would therefore be of great interest. NZ has a wealth of different kinds of subfossils, which can tell as lot about what NZ was once like before the arrival of humans – such as bones, feathers, eggshells and even the mummified bodies of birds such as moa. One of the more unusual subfossils identified are coprolites – a general word for preserved, prehistoric dung. Coprolites suspected to have originated from birds such as moa have been found in dry rockshelters and caves in the South Island in the past.

PREFACE Rising 4,205 meters (13,796 feet) above sea level, the volcanic mountain Mauna Kea is the highest peak in the Hawaiian Islands and, from its base on the floor of the Pacific Ocean, the highest mountain on earth. Its main mass is built up from flows of lava and deposits of ash; its summit and upper slopes are dotted with cinder cones from more recent fiery eruptions, the last of which occurred more than 2,000 years ago. To the northeast it descends steeply, reaching the ocean shore 27 kilometers (1 7 miles) from the summit; to the west it drops more gently to the upland Waimea plain. To the south, a high plateau built up of lava from numerous volcanic flows from both Mauna Kea and Mauna Loa forms a Saddle between the two towering volcanic peaks. Snow often whitens the summit in winter, and the name Mauna Kea is often translated in English as White Mountain. In Native Hawaiian traditions, however, “Kea” is also the abbreviated form of Wakea, the great sky god who, together with Papa, the earth mother, and other gods and forces, created the Hawaiian Islands.
