Abstract:
The red-rumped parrot (Psephotus haematonotus), which appears to be undergoing range expansion, started colonising metropolitan Melbourne ~30 years ago. The factors that have facilitated this colonisation have not been evaluated. We investigated aspects of the parrot’s ecology at six parkland sites through late autumn and winter 2006 to elucidate these factors. The predominantly ground-feeding red-rumped parrot consumed mainly seeds of exotic grass and herb species, four of which were particularly important in providing a continuous winter food resource. Two of these species were common turf grasses and their visible and concealed seeds provided >50% of the diet. Sites occupied by parrots had relatively more native trees, tall trees and dense canopy cover than unoccupied sites; this may be important in providing suitable daytime and nocturnal roost sites. Little aggressive interference competition occurred with other ground-feeding birds. Mean population density in occupied sites was 1.3 parrots ha–1. Mean flock size was 10 ± 6 and, on average, males comprised 67 ± 19% of a flock’s members. We suggest that abundant, continuously available food (seed) resources, apparently limited competition for food and the presence of suitable roosting sites are probably important in facilitating winter occupancy of parkland by red-rumped parrots in Melbourne.

Abstract:
Indonesia has been identified as the highest priority country for parrot conservation based on the number of species, endemics, and threats (trapping and smuggling). It is crucial to understand the current population status of parrots in the wild in relation to the illegal wildlife trade but the ecology and population dynamics of most parrot species in this region remain poorly understood. We conducted a parrot survey around an area of high biodiversity in the Manusela National Park, in Seram Island, Indonesia. We used a combination of fixed-radius point counts and fixed-width line transects to count multiple species of parrots. We recorded nearly 530 wild parrots from 10 species in and around Manusela National Park. The dominant parrot species were Eos bornea, Trichoglosus haematodus, and Geoffroyus geoffroyi. We applied the Savage selectivity index to evaluate poaching of parrot species in proportion to their abundance and which species had higher than expected poaching pressure. This study has important implications for the conservation status of endemic parrots (Cacatua moluccensis, Lorius domicella, and Eos semilarvata) and shows that parrots in the Manusela NP are largely threatened by poaching.

Abstract:
Despite New Guinea's importance for parrot species, there is an almost total lack of quantitative data on abundances or habitat associations of parrots on the island. We present such data for 15 parrot species within the species-rich (21 species) Crater Mountain Wildlife Management Area, Papua New Guinea. The four most abundant parrot species made up 70% of all parrots recorded in primary forest and 76% in old gardens. Several species had estimated densities of 10?60 birds per km2 and we suggest that the most abundant species on New Guinea are at least as common as those on the surrounding islands. Two species of particular conservation importance, Palm Cockatoo Probosciger aterrimus and Pesquefs Parrot Psittrichas fulgidus had estimated densities of just one bird per km2, while several other notably rare species included Dusky Lory Pseudeos fuscata and the fig-parrots Cyclopsitta diopthalma and Psittaculirostris desmarestii. Most parrot species were strongly associated with the lower and flatter areas of the site, where mature secondary forest dominated. Again, this is a pattern shared with parrots on nearby islands, and the finding emphasizes the importance of protecting lower-altitude mature forests within the region.

Abstract:
Abstract Parrots are vocal learners and many species of parrots are capable of learning new calls, even as adults. This capability gives parrots the potential to develop communication systems that can vary dramatically over space. St. Lucia Parrot (Amazona versicolor) flight vocalizations were examined for geographic variation between four different sites on the island of St. Lucia. Spectrographic cross-correlation analysis of a commonly used flight vocalization, the p-chow call, demonstrated quantitative differences between sites. Additionally, the similarity of p-chows decreased as the distance between sites increased. Flight call repertoires also differed among sites; parrots at the Des Bottes and Quilesse sites each used one flight call unique to those sites, while parrots at the Barre de L'Isle site used a flight call that Quilesse parrots gave only while perched. It is unclear whether the vocal variation changed clinally with distance, or whether there were discrete dialect boundaries as in a congener, the Yellow-naped Parrot (Amazona auropalliata, Wright 1996). The geographical scale over which the St. Lucia Parrot's vocal variation occurred was dramatically smaller than that of the Yellow-naped Parrot. Similar patterns of fine-scale vocal variation may be more widespread among other parrot species in the Caribbean than previously documented. Variación Geográfica de las Vocalizaciones de Vuelo de Amazona versicolor Resumen. Los loros aprenden vocalizaciones y los individuos de muchas especies son capaces de aprender nuevas llamadas incluso cuando son adultos. Esta habilidad otorga a los loros el potencial de desarrollar sistemas de comunicación que pueden variar notablemente en el espacio. Se estudiaron las vocalizaciones de vuelo de Amazona versicolor para determinar la ocurrencia de variaciones geográficas entre cuatro lugares diferentes de la isla de Santa Lucía. Un análisis espectrográfico de correlación cruzada de la llamada común, conocida como “p-chow”, demostró diferencias cuantitativas entre los distintos lugares. Además, la similitud entre estas llamadas disminuyó con incrementos en la distancia entre los lugares. Los repertorios de llamadas de vuelo también difirieron entre lugares: los loros de las localidades de Des Bottes y Quilesse emplearon una llamada de vuelo exclusiva para cada uno de esos sitios, mientras que los de Barre De L'Isle usaron como llamada de vuelo una vocalización que los de Quilesse sólo emitieron cuando estaban posados. No queda claro si las vocalizaciones cambian clinalmente con la distancia, o si existen distintos tipos discretos de vocalizaciones, como en su congénere A. auropalliata (Wright 1996). La escala geográfica a la que se da la variación vocal en A. versicolor es bastante menor que aquella a la cual se presenta en A. auropalliata. Patrones similares de variación vocal a pequeña escala pueden ser más comunes en otras especies de loros del Caribe de lo que se ha documentado hasta ahora.

Abstract:
Parrots are traded globally and pose a substantial risk for disease transmission involving parrot-specific pathogens. Parrot bornavirus (PaBV) belongs to the Bornaviridae family and encompasses two clades: alphapsittaciforme (PaBV-1 to -4, PaBV-7, and -8) and betapsittaciforme (PaBV-5 and PaBV-6). These clades cause proventricular dilatation disease, a chronic disease affecting all parrot species. PaBV infections can persist for varying durations in parrots, but the transmission routes are still not well understood. Therefore, surveillance of PaBV-infected parrots is necessary for disease control and improving psittacine aviculture. This study used isolated PaBV-4 NTUCL7 and PaBV-5 NTUCL54 strains to establish and validate two serological diagnostic methods: immunoblotting (IB) and immunocytochemical staining (ICC). To determine the prevalence of PaBV in parrots in Taiwan, 370 clinical serum samples were collected from 13 collaborative veterinary hospitals during a 1-year surveillance period. Serological surveillance revealed a seropositivity rate of 25.68%. Among the seropositive samples, 91.58% were infected with alphapsittaciforme PaBV, demonstrating the predominance of this viral clade in parrots. An analysis of risk factors also demonstrated an association between seropositivity and parrot genera, age, and clinical signs. Cohen’s kappa coefficient analysis showed a high degree of similarity (kappa value = 0.975) between the IB and ICC results, which shows that these serological diagnostic measures are robust. This study established two reliable serological diagnostic measures that are instrumental in serological surveillance, particularly in one of the major parrot-exporting regions. The surveillance results increase the understanding of PaBV infection and associated risk factors and allow methods to be devised for the conservation and protection of parrot populations.

Abstract:
The New Zealand (NZ) native parrots kākāpō, kākā and kea are classified as critically endangered, endangered and vulnerable respectively. Successful reproduction of kākāpō and kākā is linked to years of high levels of fruiting in native flora (mast years). To assess a possible hormonal link between native plants and reproductive success in these parrots in mast years, we examined the ligand-binding domains (LBD) of the progesterone receptor (PR), androgen receptor (AR), estrogen receptor 1 (ESR1) and estrogen receptor 2 (ESR2) in NZ native (kākāpō, kākā, kea and kākāriki) and non-native (Australian cockatiel) parrots and compared them with those in the chicken. The amino acid sequences for PR, AR, ESR1 and ESR2 shared >90% homology among the NZ parrots, the cockatiel and, in most cases, the chicken. The exception was for the ESR1 LBD, which contained an extra eight amino acids at the C-terminal in all the parrots compared with the chicken and with published sequences of non-parrot species. These results support the notion that the ESR1 LBD of parrots responds differently to putative oestrogenic compounds in native trees in NZ during times of intermittent masting. In turn, this may provide important information for generating parrot-specific bioassays and linkages to steroidogenic activity in native plants.

Abstract:
Maluku is widely considered as a global avifauna hotspot. However, illegal parrot trades threatens numerous species to extinction. To date, there is no study on the extent of illegal trade in Maluku, which as a result, hampers efforts at targeting conservation initiatives. The aims of this study are to identify the pattern of illegal parrot trade, to identify factors that contribute to illegal parrot trade, and to identify actors involved in illegal parrot trade in Maluku and North Maluku Provinces. The study found that the number of wildlife rescued in 2018 was 1,402 individuals. Surprisingly, 84% (1,177 individuals) of the rescued wildlife were birds and approximately 96% (1,135 individuals) of the birds were parrots. Furthermore, the most commonly rescued parrots (90%) were from illegal trade seizures, and the remainder were handed over voluntarily by local communities. These trends indicate that the traffic of illegal parrot trade is extremely high. Meanwhile, the small number of handovers for birds indicates that there is an insufficient understanding and awareness among locals about wildlife laws and ecological values. The study identified three factors contributing to illegal parrot trade, which are the high potential for obtaining parrots with exotic appearances; the economic value of wild-caught parrots; and overall accessibility. The characteristics of the trade involved actors that can be defined as subsistence and opportunist harvesters, that work with several intermediaries, and consumers demand for pets. To overcome these challenges, there are two strategies which are proposed based on this research: (1) expand the upstream strategy focusing on protecting parrots in their habitats and empowering local communities to be involved in conservation; and (2) engage more on downstream strategies of emphasizing law enforcement and raising awareness.

Abstract:
Parrots include in birds of Aves class and Psittaciformes order. In Indonesia, parrots in known by their local species names such as Nuri (true parrot), Kakatua (Cockatoo), and Perkici (Loriini). Parrots can be found almost in all type of habitat in Halmahera Island, Maluku Utara Province, from mangrove forest to tropical rainforest in lowlands and highlands in Halmahera Island. The research aims to describe community activities in the exploitation of parrots around the Aketajawe Lolobata National Park, Halmahera Island. The study uses the ex-post facto method with the questionnaire as the instrument to interview the communities consist of the catcher, seller, and owner of parrots. Research result data is analyzed descriptively and presented in the form of tables and charts. The result shows that there are five kinds of parrots that are caught, sold, and raised by the communities of Gitaraja, Bale, Koli, and Kosa Village. The exploited birds are Kasturi Ternate (Lorius garrulus) Nuri Kalung Ungu (Eos scuamata), Nuri Bayan (Eclectus roratus), Kakatua Putih (Cacatua alba) and Kakatua Jambul Kuning (Cacatua galerita). The number of parrots being caught during 2013-2016 is 327, 320 are sold, and 213 are raised. The highest percentage of parrot catching and selling is 21% in 2013, and the lowest is 2% in 2016-2018. The highest percentage of raising is 8% in 2015, and the lowest is 3% in 2018. Kasturi Ternate (Lorius garrulus) is the species with the highest rate of exploitation.

Abstract:
Literature’s Most Human Bird: Beckett and His Parrots. Perhaps more so than any other animal, the parrot has achieved a unique status as a cultural symbol and cliché in Western literature. Ever since its first introduction in Europe by Alexander the Great, the parrot’s ability to imitate human language has been a never-ending source of fascination for human society. In literature, the talking parrot has always evoked the question of what it means to be human, reminding us of the painful possibility that language and thought might be merely a product of mindless imitation, and thus of no greater value. The parrot features as a significant presence in practically every work written by Samuel Beckett during his first thirty years as a writer. This article inscribes Beckett into a tradition of utilizing parrots as means of satire, in which the meaninglessness and mindlessness of everyday language and inveterate phrases are compared with the pure sound-imitations uttered by the bird. The parrot may be studied as a motif more deeply integrated into the Beckett oeuvre than his complex web of quotes and references to the literary tradition and writers such as Gustave Flaubert and James Joyce. One can argue that the parrot embodies the Beckettian theme of repetition and difference, present at almost every level of his writing. In this article, this assertion is explored through an interpretation of Lucky’s monologue in En attendant Godot (1952), based on the principles of aural similarity and repetition gone wrong.

Abstract:
The circovirus Beak and feather disease virus (BFDV) causes psittacine beak and feather disease (PBFD) that is characterised by a chronic disease process associated with feather abnormalities, beak deformities and eventual death in various species of birds in the order Psittaciformes. This disease is seen in captive and wild psittacine species in Australia and several other countries and is a significant threat to the survival of some endangered psittacine species. This thesis reports on genetic studies that have furthered the understanding of the diversity of BFDV present within Australia. These studies have optimised methods of detecting BFDV. They have also resulted in the production of an immunogenic and antigenic recombinant BFDV Capsid protein that could lead to alternate methods of producing viral antigen for serological tests and the development of a BFDV vaccine. To assess the optimal method of the detection of BFDV infection, feather and blood samples were submitted by referring veterinarians throughout Australia from psittacine birds tentatively diagnosed with PBFD or with a history of being in contact with PBFD-affected birds. These samples were examined by 3 procedures commonly used to detect BFDV infection: a polymerase chain reaction (PCR) assay and haemagglutination (HA) for the detection of virus, and haemagglutination inhibition (HI) tests for the detection of virus antibody in response to infection. Of the samples examined from 623 psittacine birds, the prevalence of BFDV DNA in feather samples detected by PCR was 18.85%. There was a strong correlation between PCR and HA testing of feather samples, although possible false-positive and false-negative PCR and HA results were obtained in some samples. Of the 143 birds that were PCR feather-positive only 2 had detectable HI antibody and these birds were also HA feather-negative, which suggests that they were developing immunity to recent infection. All birds with HI antibody were feather HA negative. Despite the rare occurrence of PBFD in cockatiels (Nymphicus hollandicus), 2 of the 13 samples collected from this species were PCR and HA positive indicating that this species can be infected with BFDV. Three studies were undertaken to further our understanding of the genetics of BFDV in Australian avifauna: sequence analysis of the BFDV detected in a grey cockatiel (Nymphicus hollandicus), a species normally considered resistant to infection with BFDV; analysis of the genome of BFDV present in lorikeets (Trichoglossus sp.) in Australia; and analysis of the genome of BFDV detected in endangered swift parrots (Lathamus discolor). Sequence analysis of the entire genome of the cockatiel BFDV isolate revealed that it clustered phylogenetically with 2 other viruses, one from a sulphur crested cockatoo (SCC1-AUS) and one from a Major Mitchell cockatoo (MMC-AUS), which suggests that this isolate from the grey cockatiel was not a cockatiel-specific biotype. Phylogenetic analysis of the ORF V1 of BFDV detected in 7 lorikeets demonstrated these 7 isolates clustered phylogenetically with other BFDV isolates obtained from Loriidae species elsewhere in the world and confirmed the presence of a loriid-specific genotype. Phylogenetic analysis of the sequence data generated from ORF V1 of virus detected in 2 endangered swift parrots provided evidence they were also infected with BFDV genotypes derived from other species of birds, one isolate clustering with viruses from a Loriidae genotype and the other with isolates derived from species of Cacatuidae and Psittacidae. As part of this research, a baculovirus expression system was successfully developed for the production of recombinant BFDV Capsid protein. Inoculation of this protein into chickens resulted in the development of HI antibody, which demonstrated its immunogenicity. When used as an antigen in HI tests it detected antibody in virus-infected birds, which demonstrated its antigenicity. This protein offers potential application as an antigen for the development of serological tests and as an immunogen for incorporation into vaccines for control of PBFD.

Abstract:
The world is now thought to have entered into a sixth mass extinction event, which unlike previous mass extinctions, is entirely driven by human impacts. The early colonisation of humans has led to as many as a thousand endemic bird species becoming extinct, while increasing human mediated transport of species around the world has led to invasive species becoming one of the largest global conservation challenges of today. Studies in molecular ecology can help us to unravel how evolutionary processes are important for informing conservation and invasion biology by understanding genetic mechanisms that enable populations to grow and adapt in a changing world. As genetic diversity is essential for the persistence of populations, this thesis aims to understand how species respond, at a genetic level, to human-driven events such as the reduction of a population to a small size, or the introduction of a species into a novel environment. The findings demonstrate the important use of genetic markers for phylogenetic reconstruction and understanding population structure. These phylogenetic reconstructions examine taxonomic distinctiveness and patterns of evolution, and allow the identification of ancestral origins for invasive ring-necked parakeets. Evidence from genetic phylogroups, trade data and drivers of population growth, highlight how multiple introductions and patterns of climate matching between the native and invasive ranges of ring-necked parakeets, are mechanisms for invasion success. In contrast to mild genetic bottleneck effects, high levels of diversity and the avoidance of problems associated with small population size within populations of invasive ring-necked parakeet, the endemic Seychelles black parrot exhibited a reduction in population size and reduced levels of genetic diversity over time. Moreover, the inclusion of new genetic data for a number of extinct parrot species enabled an examination of the loss of broader scale phylogenetic diversity, important for ecosystem function, as a result of extinctions of endemic species and invasions of ring-necked parakeets. The findings from this thesis have already been applied to conservation and invasion biology by contributing to the reclassification of the endemic Seychelles black parrot, and to improving the ability of ecological niche models to predict areas suitable for future invasions of ring-necked parakeets. Furthermore they provide a novel approach to identifying potential candidates as ecological replacements to restore ecosystem function and lost phylogenetic diversity.

Abstract:
It is now widely understood that species boundaries are often semipermeable, and that hybridisation and introgression occur frequently in nature and have the potential to dramatically alter the evolutionary trajectory of the taxa involved. Hybrid zones, regions where genetically distinct populations overlap and produce hybrid offspring, provide a valuable opportunity to gain insight into the speciation process. They can arise without a period of isolation when distributions span environmental gradients or ecotones (primary hybrid zone), or as a result of secondary contact following allopatric divergence (secondary hybrid zone), and their structure and ultimate evolutionary outcome can vary greatly depending on the strength of pre- and post-mating barriers to gene flow, as well as the impact of other evolutionary forces (e.g. selection). The dawn of the age of genomics offers great possibility for the analysis of potentially hybridising taxa. In this thesis, I employ a genomic approach alongside more traditional molecular and non-molecular techniques to examine the presence and influence of hybridisation on two native Australian parrot species, the pale-headed (Platycercus adscitus) and eastern rosellas (P. eximius). Together, these species, which are each composed of readily identifiable subspecies, span the eastern seaboard of Australia, with species and subspecies reportedly hybridising where their ranges overlap.

Abstract:
Similarities in brain size, life histories, psychology and behaviour in parrots, corvids and apes suggest that certain socio-ecological selection pressures may have driven the convergent evolution of cognition in these families. However, very little is known about parrot behaviour and cognition, outside of African greys and kea. Therefore, captive red-shouldered macaws (Diopsittaca nobilis) and black-headed caiques (Pionites melanocephala) were presented with a variety of tasks to assess their social and physical cognition and behavioural flexibility. Although these species possess many similarities in their life history and ecology, there are also substantial differences in their morphology and natural habitats that could have driven differences in their cognitive evolution. Observations of social and physical interactions in both species revealed that macaws engaged in high levels of affiliative behaviour, and object neophobia, whereas caiques displayed high levels of social play and object exploration. However, such differences did not appear to result in differences in their social or physical cognition. Macaws and caiques displayed comparable performances on Serial Reversal Learning tasks (as an index of behavioural flexibility). Both species also demonstrated similar performances on two Means-End transfer tasks and a series of innovative foraging tasks that were designed to assess their comprehension of object relationships. However, macaws and caiques appeared to solve such problems by generalising learned information across novel tasks. Overall, these findings suggest that these two species may approach certain socio-ecological problems using flexible cognition that may be generalised across different problems, supporting claims for a domain general intelligence.
