Swift Parrot Husbandry Guidelines for Photograph by Greg Miles, July 2011 Swift Parrot Lathamus discolor (Aves: Psittacidae) Date By From Version 2019 Crystal Capach RARES Fndn v 1 WORK HEALTH AND SAFETY RISKS Species Risk Category The Swift Parrot (Lathamus discolor) is considered a low risk, or innocuous parrot. The largest risk of harm would occur by the beak through biting, so care should be taken whilst handling or restraining the bird to reduce the chances of being bitten. WHS SUMMARY Though generally non aggressive in nature, injury may still occur through mishandling the bird, or through something as simple as working within the enclosure. A keeper must always take precautions whilst working to ensure their own safety and the safety of their fellow workers. If it happens that a serious injury occurs within the workplace, the regulator must be notified immediately in accordance with the Work Health and Safety Act 2011 (Workcover NSW). Workplace Risk Types 1. Biological There is a risk of zoonotic diseases being contracted when coming into contact with this species, as well as other bird species within the Psittacidae family. Namely, the highest zoonotic risk is the bacterial disease psittacosis, also known as ornithosis and chlamydiosis. Transmitted mainly through the inhalation of contaminated airborne faecal matter, feather dander, or beak-to-mouth contact, this disease can be diagnosed through the flu-like symptoms and respiratory tract illness presented. Maintaining proper hygiene practices and regular screening of birds should help prevent the zoonotic spread of this disease (Harkinezhad et al. 2009; West 2011). This disease as well as several others will be discussed further in Section 8. 2 2. Chemical The cleaning and regular maintenance of any enclosure carries the risk of injury from chemicals used during the cleaning process. Corrosive chemicals used such as bleach to clean water bowls or ponds will cause damage to the eyes if splashed into them, and may cause damage to the skin if continued contact occurs with the chemical. As such, MSDS (Material Safety Data Sheet) booklets should be located in easily accessible areas within the vicinity of the area where the chemicals are stored. Additionally PPE (Personal Protective Equipment) should be made available to all workers who come in to contact with this chemical, including (but not limited to) protective eye gear, rubber gloves, and overalls (Pers. Obs. Crystal Capach). 3. Environmental Working in an outdoor environment lends the risk of being exposed to poor conditions throughout the year. Whilst working in an enclosure preparations should be made to endure sun exposure, extremes in heat/cold, and strong winds. Protective equipment including sun screen, sunglasses, and hats should be worn to protect the body from sun damage. In extreme temperatures, care should be taken to wear appropriate clothing for the weather, and maintain hydration (for heat). In the case of strong winds, it is important to keep an eye out for any structure which may be damaged and could fall leading to injury (e.g. falling tree branches) (Pers. Obs. Crystal Capach). 4. Ergonomic Enclosures should be designed with not only the safety and security of the birds in mind, but also allowing for ease of movement and reduction of strain for workers whilst performing daily maintenance tasks, including cleaning and enclosure repairs. Keepers should not be forced to bend or strain their back in the process of entering the enclosure by making sure the door is tall enough. Additionally, proper posture should be maintained during maintenance to reduce strain on the back and neck (Pers. Obs. Crystal Capach). 3 5. Physical Physical labour carries the risk of injury through common activities such as heavy lifting or repetitive movement. It is always important to ensure that strain is not placed on the body (e.g. back and neck) by lifting objects heavier than 20kg (or sometimes objects more than half one’s body weight) without assistance, and signage around the workplace should indicate as much. Repetitive movement or strain related injuries can be avoided by maintaining proper posture while lifting (Pers. Obs. Crystal Capach). 6. Psychological Forming close attachments to animals being cared for can result in grief upon the death of an individual. Grief can adversely impact upon the mental wellbeing of a keeper, with reactions being immediate, or manifesting over time. Management through the use of counselling should be taken into consideration and be offered should a keeper be considered under psychological strain. Unresolved psychological strain may eventuate in negative interactions with fellow workers or other animals within the workplace (Pers. Obs. Crystal Capach). 4 TABLE OF CONTENTS WORK HEALTH AND SAFETY RISKS ...............................................................................................................................2 TABLE OF CONTENTS ..............................................................................................................................................................5 1 INTRODUCTION................................................................................................................................................................8 2 TAXONOMY ........................................................................................................................................................................9 2.1 NOMENCLATURE ................................................................................................................................................................9 2.2 SUBSPECIES.........................................................................................................................................................................9 2.3 RECENT SYNONYMS ..........................................................................................................................................................9 2.4 OTHER COMMON NAMES..................................................................................................................................................9 3 NATURAL HISTORY......................................................................................................................................................10 3.1 MORPHOMETRICS.............................................................................................................................................................10 3.1.1 Mass And Basic Body Measurements ...............................................................................................................10 3.1.2 Sexual Dimorphism ..............................................................................................................................................10 3.1.3 Distinguishing Features ......................................................................................................................................13 3.2 DISTRIBUTION AND HABITAT.........................................................................................................................................14 3.3 CONSERVATION STATUS .................................................................................................................................................15 3.4 LONGEVITY .......................................................................................................................................................................15 3.4.1 In the Wild..............................................................................................................................................................15 3.4.2 In Captivity ............................................................................................................................................................15 3.4.3 Techniques Used to Determine Age in Adults .................................................................................................15 4 HOUSING REQUIREMENTS .......................................................................................................................................16 4.1 EXHIBIT/ENCLOSURE DESIGN ........................................................................................................................................16 4.2 HOLDING AREA DESIGN .................................................................................................................................................19 4.3 SPATIAL REQUIREMENTS ................................................................................................................................................19 4.4 POSITION OF ENCLOSURES..............................................................................................................................................19 4.5 WEATHER PROTECTION ..................................................................................................................................................19 4.6 TEMPERATURE REQUIREMENTS.....................................................................................................................................20 4.7 SUBSTRATE .......................................................................................................................................................................20 4.8 NESTBOXES AND/OR BEDDING MATERIAL ..................................................................................................................21 4.9 ENCLOSURE FURNISHINGS..............................................................................................................................................22

    Eastern rosella (Platycercus eximius) Class: Aves Order: Psittaciformes Family: Psittaculidae Characteristics: The Eastern rosella averages 30 cm (12 in) in length and 99gm (3.5oz) in weight. With a red head and white cheeks, the upper breast is red and the lower breast is yellow fading to pale green over the abdomen. The feathers of the back and shoulders are black, and have yellowish or greenish margins giving rise to a scalloped appearance that varies slightly between three subspecies and the sexes. The wings and lateral tail feathers are bluish while the tail is dark green. Range & Habitat: Behavior: Like most parrots, Eastern rosellas are cavity nesters, generally Eastern Australia down to nesting high in older large trees in forested areas. They enjoy bathing in Tasmania in wooded country, puddles of water in the wild and in captivity and frequently scratch their open forests, woodlands and heads with the foot behind the wing. Typical behavior also includes an parks. Nests in tree cavities, undulating flight, strutting by the male, and tail wagging during various stumps or posts. displays such as courting, and a high-pitched whistle consisting of sharp notes repeated rapidly in quick succession. Reproduction: Breeding season is influenced by rain and location. Courting male bows while sounding out mating call followed by mutual feeding and then mating. Female alone incubates eggs while male bring food. 2-9 eggs will hatch in 18 - 20 days. Hatchlings are ready to leave the nest in about 5 weeks but may stay with their parents for several months unless there is another mating.

  • Australia: Tasmania and the Orange- Bellied Parrot 24 – 29 October 2020 24 – 29 October 2021
    AUSTRALIA: TASMANIA AND THE ORANGE- BELLIED PARROT 24 – 29 OCTOBER 2020 24 – 29 OCTOBER 2021 The handsome Orange-bellied Parrot is the primary target on this tour. www.birdingecotours.com [email protected] 2 | ITINERARY Australia: Tasmania and the Orange-bellied Parrot Adjoined to the mainland until the end of the last glacial period about ten thousand years ago, Tasmania is both geographically and genetically isolated from Australia. Through the millennia this island has developed its own unique set of plants and animals, including twelve avian endemics that include Forty-spotted Pardalote, Green Rosella, and Strong-billed Honeyeater. Beyond the endemics Tasmania also harbors several species which winter on the mainland and breed on Tasmania, such as Swift Parrot and Orange-bellied Parrot. These two breeding endemics are globally Critically Endangered (IUCN) and major targets on this tour. Forty-spotted Pardalote is one of the Tasmanian endemics we will target on this tour. Our search for the endemics and breeding specialties of Tasmania is set within a stunning backdrop of rugged coastlines, tall evergreen sclerophyll forests, alpine heathlands, and cool temperate rainforests, undoubtedly enriching our experience here. In addition, due to the lack of foxes many marsupials are notably more numerous in Tasmania, and we should be able to observe several of these unique animals during our stay. For those wishing to continue exploring Australia, this tour can be combined with our set of Australia tours: Australia: from the Outback to the Wet Tropics, Australia: Top End Birding, and Australia: Southwest Specialties. All four Australia tours could be combined. We can also arrange other extensions (e.g., sightseeing trips to Sydney, Uluru, etc., and pelagic trips).

Black gum (E. ovata). The more of these gums in the Photo: Rob Wiltshire area, and the closer they are to tree-hollows suitable for nesting, the better for the parrots. Swift Parrots have declined dramatically to fewer than 1,000 breeding pairs, chiefly because their forest habitat has b. been cleared and altered. All the main forest types used by breeding Swift Parrots have been affected in Tasmania; for instance, less than 30% of the original area of dry Blue gum forest remains, and only 3% of Black gum forest. Another significant threat is death or injury when their rapid flight causes them to collide with windows, fences and overhead wires. Changes to habitat can lead to increased competition from other birds which use tree-hollows for nesting in degraded areas. Because their survival is so tied to their breeding habitat, the fate of Swift Parrots is in our hands - every little action that we take today can go a long way towards ensuring that Photo: Chris Tzaros future generations continue to see and hear these birds.

  • New Caledonia, Fiji & Vanuatu
    Field Guides Tour Report Part I: New Caledonia Sep 5, 2011 to Sep 15, 2011 Phil Gregory The revamped tour was a little later this year and it seemed to make some things a bit easier, note how well we did with the rare Crow Honeyeater, and Kagu was as ever a standout. One first-year bird was rewarded with a nice juicy scorpion that our guide found, and this really is a fabulous bird to see, another down on Harlan's famiy quest, too, as an added bonus to what is a quite unique bird. Cloven-feathered Dove was also truly memorable, and watching one give that strange, constipated hooting call was fantastic and this really is one of the world's best pigeons. Air Calin did their best to make life hard with a somewhat late flight to Lifou, and I have to say the contrast with the Aussie pilots in Vanuatu was remarkable -- these French guys must still be learning as they landed the ATR 42's so hard and had to brake so fiercely! Still, it all worked out and the day trip for the Ouvea Parakeet worked nicely, whilst the 2 endemic white-eyes on Lifou were got really early for once. Nice food, an interesting Kanak culture, with a trip to the amazing Renzo Piano-designed Tjibaou Cultural Center also feasible this The fantastic Kagu, star of the tour! (Photo by guide Phil year, and a relaxed pace make this a fun birding tour with some Gregory) terrific endemic birds as a bonus. My thanks to Karen at the Field Guides office for hard work on the complex logistics for this South Pacific tour, to the very helpful Armstrong at Arc en Ciel, Jean-Marc at Riviere Bleue, and to Harlan and Bart for helping me with my bags when I had a back problem.

We started the tour in Cairns in Far North Queensland, where we found ourselves surrounded by multiple habitats from the tidal mudflats of the Cairns Esplanade, the Great Barrier Reef and its sandy cays, lush lowland and highland rainforests of the Atherton Tablelands, and we even made it to the edge of the Outback near Mount Carbine; the next leg of the tour took us south to Southeast Queensland where we spent time in temperate rainforests and wet sclerophyll forests within Lamington National Park. The third, and my favorite leg, of the tour took us down to New South Wales, where we birded a huge variety of new habitats from coastal heathland to rocky shorelines and temperate rainforests in Royal National Park, to the mallee and brigalow of Inland New South Wales. The fourth and final leg of the tour saw us on the beautiful island state of Tasmania, where we found all 13 “Tassie” endemics. We had a huge list of highlights, from finding a roosting Lesser Sooty Owl in Malanda; to finding two roosting Powerful Owls near Brisbane; to having an Albert’s Lyrebird walk out in front of us at O Reilly’s; to seeing the rare and endangered Regent Honeyeaters in the Capertee Valley, and finding the endangered Swift Parrot on Bruny Island, in Tasmania.

  • Tasmania and the Orange-Bellied Parrot – Set Departure Trip Report
    AUSTRALIA: TASMANIA AND THE ORANGE-BELLIED PARROT – SET DEPARTURE TRIP REPORT 22 – 27 OCTOBER 2018 By Andy Walker We enjoyed excellent views of several of the Critically Endangered (IUCN) Orange-bellied Parrots during the tour. www.birdingecotours.com [email protected] 2 | TRIP REPORT Australia: Tasmania and the Orange-bellied Parrot: October 2018 Overview This short Tasmania group tour commenced in the state capital Hobart on the 22nd of October 2018 and concluded back there on the 27th of October 2018. The tour focused on finding the state’s endemic birds as well as two breeding endemic species (both Critically Endangered [IUCN] parrots), and the tour is a great way to get accustomed to Australian birds and birding ahead of the longer East Coast tour. The tour included a couple of days birding in the Hobart environs, a day trip by light aircraft to the southwest of the state, and a couple of days on the picturesque and bird-rich Bruny Island. We found, and got very good views of, all twelve endemic birds of Tasmania, these being Forty- spotted Pardalote, Green Rosella, Tasmanian Nativehen, Scrubtit, Tasmanian Scrubwren, Dusky Robin, Strong-billed, Black-headed, and Yellow-throated Honeyeaters, Yellow Wattlebird, Tasmanian Thornbill, and Black Currawong, as well as the two Critically Endangered breeding endemic species (Orange-bellied Parrot and Swift Parrot), of which we also got excellent and prolonged views of a sizeable proportion of their global populations. Other highlights included Little Penguin, Hooded Dotterel, Freckled Duck, White-bellied Sea Eagle, Wedge-tailed Eagle, Grey Goshawk, Laughing Kookaburra, Yellow-tailed Black Cockatoo, Blue-winged Parrot, Pink Robin, Flame Robin, Scarlet Robin, Striated Fieldwren, Southern Emu-wren, and Beautiful Firetail.

  • Swift Parrot (Lathamus Discolor)
    Action Statement Flora and Fauna Guarantee Act 1988 No. 169 Swift Parrot Lathamus discolor Description and distribution The Swift Parrot Lathamus discolor Shaw 1790 (Psittaciformes: Platycercidae) is a non-breeding winter migrant to the mainland from Tasmania. It has a restricted breeding area in the east of Tasmania, arriving on the mainland in autumn to spend the winter period in foraging groups inhabiting forests and woodlands in south-east Australia. Swift Parrots are small to medium size birds reaching a length of 245mm, including a 120mm tail. Sexes are similar, except that the female is generally duller than the male. General plumage is green. Crown and ear coverts are dark blue and the face is red with yellow margins. Underparts are lighter and paler than back. Shoulder and underwing coverts are red, eye yellow and bill a horn colour. Brown (1989) and Higgins (1999) give Swift Parrot Latham discolor a full description of the species. (Photo: Mike Carter) Habitat In Victoria, the over-wintering habitat of the Swift Parrot is eucalypt forests and woodlands consisting primarily of the winter-flowering Grey Box (Eucalyptus microcarpa), Red Ironbark (Eucalyptus tricarpa), Mugga Ironbark (Eucalyptus sideroxylon) (far north-east Victoria), Yellow Gum (Eucalyptus leucoxylon) and White Box (Eucalyptus albens) (Brown 1989; Emison et al. 1987, C. Tzaros pers. comm.). They feed in gregarious flocks on nectar where eucalypts are in blossom or where lerps/psyllids are common. Blakers et al. (1985) describes Swift Parrots feeding on lerp psyllids amongst Red Gum (Eucalyptus camaldulensis) as Distribution in Victoria well as the aforementioned species. + before 1970, since 1970 [source: DSE 2004] In general terms, Grey Box flowers in autumn when the birds first arrive, followed by the Ironbarks with Yellow Gum and White Box often flowering Conservation status late prior to birds departing for Tasmania.

  • Winter Habitat Use by the Endangered, Migratory Swift Parrot (Lathamus Discolor) in New South Wales
    CSIRO PUBLISHING www.publish.csiro.au/journals/emu Emu, 2008, 108, 81–89 Winter habitat use by the endangered, migratory Swift Parrot (Lathamus discolor) in New South Wales Debra L. Saunders A,B and Robert HeinsohnA AThe Fenner School of Environment and Society, The Australian National University, Canberra, ACT 0200, Australia. BCorresponding author. Email: [email protected] Abstract. Migratory birds are dependent on a combination of suitable wintering, migration and breeding habitats. Identification and protection of these habitats is essential for the conservation of the birds. The endangered Swift Parrot (Psittacidae:Lathamus discolor) migrates north from Tasmania to south-eastern mainland Australia in search of suitable winter food resources. This 5-year study examines the use of known winter foraging habitats by Swift Parrots on a state- wide scale not previously attempted. Swift Parrots used a diversity of winter foraging habitats in regions of the coast and western slopes of New South Wales each year, including several habitats that occur in endangered ecological communi- ties. The abundance of Swift Parrots in New South Wales fluctuated significantly between years and regions, with coastal areas providing important drought-refuge habitats for a large proportion of the population. Over half of all foraging sites were used repeatedly, highlighting their likely importance for conservation. Landscapes containing winter foraging habitat included scattered trees, remnant vegetation and continuous forests, and Swift Parrots foraged extensively on lerp and nectar from a diversity of tree species within these. The occurrence of Swift Parrots at foraging sites was primarily asso- ciated with the abundance of lerp, nectar and non-aggressive competitors.

They daz- zle the beholder with every color in the rainbow (figure 3). They range in size from tiny pygmy parrots weighing just over 10 grams to giant macaws weighing over a kilogram. They consume a wide variety of foods, including fruit, seeds, nectar, insects, and in a few cases, flesh. They produce large repertoires of sounds, ranging from grating squawks to cheery whistles to, more rarely, long melodious songs. They inhabit a broad array of habitats, from lowland tropical rainforest to high-altitude tundra to desert scrubland to urban jungle. They range over every continent but Antarctica, and inhabit some of the most far-flung islands on the planet. They include some of the most endangered species on Earth and some of the most rapidly expanding and aggressive invaders of human-altered landscapes. Increasingly, research into the lives of wild parrots is revealing that they exhibit a corresponding variety of mating systems, communication signals, social organizations, mental capacities, and life spans.
