Parrots and Their Interesting Habits/Parts by the World Parrot Trust Parrots and Their Interesting Habits/Parts by the World Parrot Trust A Duchess Lorikeet acrobatically forages for nectar with its unique brush tongue, twisting this way and that and clinging upside down to branches. A female Vasa Parrot experiences an extraordinary plumage change when coming into breeding condition. And the Kea includes general mayhem in some of its daily habits. And the list goes on: parrots as a group, right from the start, are fascinating creatures, but some species are definitely edgier than others. Some of these beguiling birds have evolved some very interesting behaviours and/or appendages. The Lories: Unique adaptation for special food Lories and lorikeets, from the subfamily Loriinae, have glossy, colourful plumage and elongated bills – but the most interesting part of these birds is their brush‐like tongue, coated on the tip with papillae, or finger‐like projections. Built for specialized feeding on nectar, these handy accessories harvest pollen, nectar and sometimes an insect or two, all the while spreading around valuable genetic material from flower to flower – thereby ensuring future reproduction of these vital plants. And they do this all in the comfort of the warm, tropical regions of the world: lories and lorikeets are confined to an area that © neoporcupine All rights reserved. License: Creative encompasses the eastern Pacific Ocean islands west to Commons 2 Mindanao in the S Philippines and Sunda Islands in Indonesia. The Kakapo: Love is in the air The owlish, quiet‐mannered Kakapo would be an oddity without its ambitious breeding habits: its lack of the power of flight, island isolation and invisibility in the forest it lives in make it a strange one indeed. But this bird does one better: its determination to breed makes it legendary. The Kakapo, being flightless, is of course confined to the ground – but it makes the most of it. The male Kakapo, once old enough to breed, builds an epic arena from which to declare its availability to the opposite sex. Each male has an approximately 50‐hectare domain in which it maintains up to ten conspicuous bowl‐like excavations. It is in these bowls that it proclaims its readiness to available females – by emitting loud (there aren’t many of these guys left, so they have to be VERY loud) booming calls, beginning at dusk every night, on and on, for about three months. Once a female presents herself the male proceeds with all haste to do the deed (again, there aren’t many of them – especially females) thereby preserving his seed. A very important endeavour for a species in which the total world population numbers 120. The Vasa Parrot: Pardon me while I change into something more…yellow The Vasa Parrot is a marvelous, jet‐black parrot from Madagascar – a wonderful character that has a wide range of calls in its repertoire. Whistling, puppy‐like yapping, harsh squawks, raucous yells, and vibrating, grating sounds are some of the noises that come from this parrot and are enjoyed by other woodland creatures, but that’s not the strangest thing. More bizarre is the female Vasa in breeding condition: in a move that would seem counterintuitive to attracting a male the females lose all the feathers on their head, which then turns canary‐ yellow. The bird goes from parrot‐like to vulturine in one rapid step – all to aid the reproduction of its kind. Hanging Parrots: To sleep, perchance to dream…upside down Bats, it seems, have not cornered the market on unusual sleep positions. There is a group of parrots that do the same thing. Hanging parrots, aptly titled, do just that: they sleep or rest hanging upside down. These small parrots spend their lives in trees – and they are comfortable doing just about everything in them. They are perfectly adapted for their lives in tropical India, Indonesia and the Philippines – feeding on nectar, crawling about acrobatically, © sfitzgerald86 All rights reserved. License: Creative Commons 2 and then having a nice inverted lie‐in when they need to rest. And since they are quiet and mainly green in colour they are devilishly tricky to spot: a great adaptation for survival. The Kea: The Gangs of New Zealand This mottled‐green New Zealand parrot, of the genus Nestor, is a generally scarce denizen of the steep‐sided, sub‐alpine areas that most sane animals shun, but it apparently enjoys – so much so that when we do see them, we really see them. This parrot is conspicuous in that it loves to collect in gangs of 50 or more to visit car‐parks and campgrounds to rummage around in the things we humans leave sitting out while camping: tents, cars, food. Then when they’re not doing this they enjoy rolling around in the snow, bathing in puddles and engaging in other general mayhem. Keas are more puppy than parrot, with the intelligence of inquisitive children – and this makes them one of the most interesting parrots around. Eclectus Parrots: Coats of many colours Species: In biology, a species is one of the basic units of biological classification and a taxonomic rank; a group of organisms capable of interbreeding and producing fertile offspring. While in many cases this definition is adequate, more precise or differing measures are often used, such as similarity of DNA, morphology or ecological niche. (Wikipedia) It’s no surprise that when male and female Eclectus parrots were first discovered scientists thought they were two distinct species – the two birds could not be more different: males are emerald green with an orange beacon of a bill, females are candy‐apple red with stunning purple/blue highlights along the wings and belly. Then people saw © Kai Bey All rights reserved. License: Creative Commons 2 them breeding together. All the time. This, among other things, led to the conclusion that they belonged to the same species. Most parrots display sexual dimorphism (physical differences between the sexes) such as size, weight and a few colour changes, but Eclectus parrots took it to a whole other level. Cool. Odds and Ends: Weird‐looking but lovable parrots Last, but not least, we come to some real eccentrics: Pesquet’s parrots, found in mainland New Guinea, and Orange‐headed and Vulturine parrots, hailing from parts of South America. They are all charmingly weird and wonderful with their bare, raptor‐like heads and psittacine bodies – adaptations which, it is thought, better aid in the hygiene of the feathers while feeding on the pulpy fruit they enjoy. No muss, no fuss. Isn’t evolution grand! In sum, the world of parrots is an absorbing one – they are birds of high intelligence, awesome beauty and prodigious charm. And the parrots in this article are even more so – in all their mysterious and splendid ways. They will be celebrated, marveled over and hopefully protected – until the end of time. © 2009 Jamie Gilardi. All rights reserved. .

    1.13 NEW ZEALAND’S GENETIC DIVERSITY NEW ZEALAND’S GENETIC DIVERSITY Dennis P. Gordon National Institute of Water and Atmospheric Research, Private Bag 14901, Kilbirnie, Wellington 6022, New Zealand ABSTRACT: The known genetic diversity represented by the New Zealand biota is reviewed and summarised, largely based on a recently published New Zealand inventory of biodiversity. All kingdoms and eukaryote phyla are covered, updated to refl ect the latest phylogenetic view of Eukaryota. The total known biota comprises a nominal 57 406 species (c. 48 640 described). Subtraction of the 4889 naturalised-alien species gives a biota of 52 517 native species. A minimum (the status of a number of the unnamed species is uncertain) of 27 380 (52%) of these species are endemic (cf. 26% for Fungi, 38% for all marine species, 46% for marine Animalia, 68% for all Animalia, 78% for vascular plants and 91% for terrestrial Animalia). In passing, examples are given both of the roles of the major taxa in providing ecosystem services and of the use of genetic resources in the New Zealand economy. Key words: Animalia, Chromista, freshwater, Fungi, genetic diversity, marine, New Zealand, Prokaryota, Protozoa, terrestrial.

Amy Waldmann 2016 The Tasman parakeet (Cyanoramphus cookii) Photo: L. Ortiz-Catedral© ii ABSTRACT I studied the foraging ecology of the world’s only population of the critically endangered Tasman parakeet (Cyanoramphus cookii) on Norfolk Island, from July 2013 to March 2015. I characterised, for the first time in nearly 30 years of management, the diversity of foods consumed and seasonal trends in foraging heights and foraging group sizes. In addition to field observations, I also collated available information on the feeding biology of the genus Cyanoramphus, to understand the diversity of species and food types consumed by Tasman parakeets and their closest living relatives as a function of bill morphology. I discuss my findings in the context of the conservation of the Tasman parakeet, specifically the impending translocation of the species to Phillip Island. I demonstrate that Tasman parakeets have a broad and flexible diet that includes seeds, fruits, flowers, pollen, sori, sprout rhizomes and bark of 30 native and introduced plant species found within Norfolk Island National Park. Dry seeds (predominantly Araucaria heterophylla) are consumed most frequently during autumn (81% of diet), over a foraging area of ca.

Between April 2006 and June 2009 kea were captured in various parts of their range and samples of their blood were taken for blood lead analysis. All kea (n = 88) had been exposed to lead, with a range in blood lead concentrations of 0.014 – 16.55 μmol L–1 (mean ± SE, 1.11 ± 0.220 μmol L–1). A retrospective analysis of necropsy reports from 30 kea was also carried out. Of these, tissue lead levels were available for 20 birds, and 11 of those had liver and/or kidney lead levels reported to cause lead poisoning in other avian species. Blood lead levels for kea sampled in populated areas (with permanent human settlements) were significantly higher (P < 0.001) than those in remote areas. Sixty-four percent of kea sampled in populated areas had elevated blood lead levels (> 0.97 μmol L–1, the level suggestive of lead poisoning in parrots), and 22% had levels > 1.93 μmol L–1 – the level diagnostic of lead poisoning in parrots.

  • A Synopsis of the Pre-Human Avifauna of the Mascarene Islands
    – 195 – Paleornithological Research 2013 Proceed. 8th Inter nat. Meeting Society of Avian Paleontology and Evolution Ursula B. Göhlich & Andreas Kroh (Eds) A synopsis of the pre-human avifauna of the Mascarene Islands JULIAN P. HUME Bird Group, Department of Life Sciences, The Natural History Museum, Tring, UK Abstract — The isolated Mascarene Islands of Mauritius, Réunion and Rodrigues are situated in the south- western Indian Ocean. All are volcanic in origin and have never been connected to each other or any other land mass. Despite their comparatively close proximity to each other, each island differs topographically and the islands have generally distinct avifaunas. The Mascarenes remained pristine until recently, resulting in some documentation of their ecology being made before they rapidly suffered severe degradation by humans. The first major fossil discoveries were made in 1865 on Mauritius and on Rodrigues and in the late 20th century on Réunion. However, for both Mauritius and Rodrigues, the documented fossil record initially was biased toward larger, non-passerine bird species, especially the dodo Raphus cucullatus and solitaire Pezophaps solitaria. This paper provides a synopsis of the fossil Mascarene avifauna, which demonstrates that it was more diverse than previously realised. Therefore, as the islands have suffered severe anthropogenic changes and the fossil record is far from complete, any conclusions based on present avian biogeography must be viewed with caution. Key words: Mauritius, Réunion, Rodrigues, ecological history, biogeography, extinction Introduction ily described or illustrated in ships’ logs and journals, which became the source material for The Mascarene Islands of Mauritius, Réunion popular articles and books and, along with col- and Rodrigues are situated in the south-western lected specimens, enabled monographs such as Indian Ocean (Fig.

Re-establishing North Island kākā (Nestor meridionalis septentrionalis) in New Zealand A thesis presented in fulfilment of the requirements for the degree of Master of Science In Conservation Biology Massey University Auckland, New Zealand Tineke Joustra 2018 ii For Orlando, Aurora and Nayeli “I don’t want my children to follow in my footsteps, I want them to take the path next to me and go further than I could have ever dreamt possible” Anonymous iii iv Abstract Recently there has been a global increase in concern over the unprecedented loss of biodiversity and how the sixth mass extinction event is mainly due to human activities. Countries such as New Zealand have unique ecosystems which led to the evolution of many endemic species. One such New Zealand species is the kākā (Nestor meridionalis). Historically, kākā abundance has been affected by human activities (kākā were an important food source for Māori and Europeans). Today, introduced mammalian predators are one of the main threats to wild kākā populations. Although widespread and common throughout New Zealand until the 1800’s, kākā populations on the mainland now heavily rely on active conservation management. The main methods of kākā management include pest control and re-establishments. This thesis evaluated current and past commitments to New Zealand species restoration, as well as an analysis of global Psittacine re-establishment efforts.

The ecology and anatomy of scent in the critically endangered kakapo (Strigops habroptilus) A thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Zoology at Massey University, Auckland, New Zealand Anna Clarissa Gsell May 2012 Hoki, the kakapo - Photo by Dr. Luis Ortiz Catedral Kakapo chicks born in 2008;©Photo by Chris Birmingham ABSTRACT The focus of the research presented here is the analysis of feather scent emitted by a parrot, the kakapo (Strigops habroptilus) and the kakapo’s ability to perceive scent by studying the anatomy of its brain and the olfactory bulb. In addition, behavioural research was conducted to determine the capability of the kakapo’s closest relatives, the kea (Nestor notabilis) and kaka (N. meridionalis) to detect scents and to distinguish between different concentrations of scents. The strong odour of the kakapo is one of the many unique characteristics of this critically endan- gered parrot, but its sense of smell has never been described in detail. The kakapo is the largest par- rot worldwide, it is nocturnal and flightless. Kakapo are herbivorous and it is the only parrot with a lek breeding system. Males defend several display arenas during the breeding season and continu- ously produce low frequency booming calls. Females come from afar and appraise different males and choose one with which they want to mate.

  • The Responses of New Zealand's Arboreal Forest Birds to Invasive
    The responses of New Zealand’s arboreal forest birds to invasive mammal control Nyree Fea A thesis submitted to the Victoria University of Wellington in fulfilment of the requirements for the degree of Doctor of Philosophy Victoria University of Wellington Te Whare Wānanga o te Ūpoko o te Ika a Māui 2018 ii This thesis was conducted under the supervision of Dr. Stephen Hartley (primary supervisor) School of Biological Sciences Victoria University of Wellington Wellington, New Zealand and Associate Professor Wayne Linklater (secondary supervisor) School of Biological Sciences Victoria University of Wellington Wellington, New Zealand iii iv Abstract Introduced mammalian predators are responsible for over half of contemporary extinctions and declines of birds. Endemic bird species on islands are particularly vulnerable to invasions of mammalian predators. The native bird species that remain in New Zealand forests continue to be threatened by predation from invasive mammals, with brushtail possums (Trichosurus vulpecula) ship rats (Rattus rattus) and stoats (Mustela erminea) identified as the primary agents responsible for their ongoing decline. Extensive efforts to suppress these pests across New Zealand’s forests have created “management experiments” with potential to provide insights into the ecological forces structuring forest bird communities. To understand the effects of invasive mammals on birds, I studied responses of New Zealand bird species at different temporal and spatial scales to different intensities of control and residual densities of mammals. In my first empirical chapter (Chapter 2), I present two meta-analyses of bird responses to invasive mammal control. I collate data from biodiversity projects across New Zealand where long-term monitoring of arboreal bird species was undertaken.
