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:
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 need for information on Grey Parrot distribution and vegetation associations for informed management and policy decisions was the basis for this study. A nationwide survey of the Grey Parrot population and habitat status was carried out, using questionnaire and point count methods. From the results, the extent of the contemporary range of the parrots was restricted to Southern Cameroon, which harbours the rainforest. Regional parrot population means ranged from 3,487 parrots in the Littoral to 1,351,275 parrots in the East Regions. The extent of the contemporary range as a percentage of the whole country was 25.4% and as a percentage of the regions with rainforest was 44.5%. The historic range of the bird has been reduced by over 55.5%. Estimated percentage of forest lost per region ranged from 20.4% in the Centre to 57.1% in the East and South Regions. At a global level, Cameroon contributed 9% to the total extent of the range of the Grey Parrot in Africa. The range is increasingly fragmented, contracted, and lost through land-based socioeconomic activities. These degradation pressures on the range called for urgent conservation considerations for long-term survival of the parrot species and its associated biodiversity in Cameroon.

Abstract:
SummaryParrot poaching and the subsequent illegal trade in the Neotropics are exacerbating the decline in parrot populations. Little is known, however, on where, when and how parrots are poached. The goals of this study were to identify the spatio-temporal patterns of parrot poaching in order to identify ways in which poaching could be reduced, using parrot data (9,013 individuals from 27 species) collected daily in a major illicit wildlife market in Santa Cruz de la Sierra, Bolivia, in 2005. Parrot data identified the individuals by species, age, date of arrival at market, and the poaching location. Parrot poaching strongly varied seasonally, with differences among municipalities, species, and age classes. While almost 90% of parrots were poached within a 234 km radius of the market, 84% originated from seven municipalities in which two of them accounted for 56% alone. With regard to species, six of the 27 market species accounted for nearly 90% of total individuals. A disproportionate share of parrots (47%) arrived between July and September. Poaching of adults and juveniles peaked however at different times of the year, offering valuable information for species where very little is known about their breeding phenology. Contrary to the idea that most parrot trade comes from nest poaching, most poached parrots (c.70%) were adults, which outnumbered juveniles in 21 out of the 26 native species. Therefore, the detrimental effects of parrot poaching are higher than simple trade numbers would suggest when considering that harvesting of adults has a stronger impact on the population viability and risk of extinction of long-lived species. Based on the findings, we recommend the allocation of police and conservation resources to patrol particular areas at particular times of the year in order to reduce the likelihood of poaching by species, age classes, and conservation status.

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:
AbstractUnsustainable harvesting to supply the demand for pets is the second most significant threat to parrots (Psittacidae). Given that parrot keeping is widespread, in-depth and culturally sensitive research is needed to inform and develop interventions targeted at changing consumer preferences and purchasing behaviours. Parrot keeping is thought to be driven mainly by a desire for companionship (the affection hypothesis). Alternative hypotheses include a deeply ingrained culture of parrot ownership (the tradition hypothesis) or the influence of socio-economic context (the contextual hypothesis). We used the theory of planned behaviour to evaluate the relative importance of behavioural and contextual factors influencing the intention to keep the yellow-shouldered Amazon Amazona barbadensis as a pet. We interviewed 150 owners and non-owners of parrots in two locations in Macanao Peninsula, Margarita Island, Venezuela, where the primary population of this species is located. We found mixed evidence supporting both the affection and contextual hypotheses: intention to keep parrots was higher in non-owners with high education level, strong affective attitudes regarding human–animal relationships, and higher expectations about social norms (41% of explained variance). Our study expands previous research on the illegal parrot trade by taking into account behavioural measures beyond attitudes, highlighting the role of social norms frequently ignored in such research. We discuss how a behaviour change campaign could redirect affective attitudes in the human–parrot relationship, and promote new social norms that support parrot conservation. Future research should consider the inclusion of moral and injunctive norms, and monitoring of intervention effectiveness.

Abstract:
Biological invasions are often one of the main causes of global biodiversity loss. Parrots are among the most globally traded taxa and have successfully invaded urban areas. Studies analyzing alien parrot–habitat relationships are scarce in cities of the southern hemisphere. This study aims to determine habitat characteristics influencing exotic parrot species richness, presence, and composition in urban parks in Buenos Aires City and to analyze variations during breeding and non-breeding seasons. A total of 35 parks were sampled during the breeding season and the non-breeding season, and habitat variables at local and landscape scales were measured. Parrot species richness was positively associated with tree species richness and a shorter distance to the La Plata River throughout the year. During the non-breeding season, parrot species richness increased in parks with a higher abundance of tree genera such as Eugenia, Podocarpus, Olea, and Washingtonia. However, during the breeding season, parrot species richness decreased with increased environmental noise. Taxonomic richness was higher during the breeding season. The occurrence of different species and composition depended differentially on each variable, and it varied between seasons. Our findings suggest that exotic parrot richness and presence may be influenced not only by tree diversity and park proximity to green corridors but also by specific exotic tree species providing resources for the parrots. Future urban green space designs should prioritize native tree planting to support local biodiversity over exotic trees that benefit invasive bird species.

Abstract:
It is a challenging interaction design task to design for and with animals, especially when it comes to parrots as users. Not only because working with parrots requires a lot of patience, but also because there is very few related work. Parrots are highly intelligent and that is often the problem when they are kept as companion animal. Parrots need a lot of stimuli to trigger their intelligence and to keep them busy, to avoid serious problems such as unwanted behaviour or self-mutilation.The body language and the needs of my parrot were the main input and formed the basis for the project. Through an iterative process of testing a variety of existing applications, small experiments and prototypes, a couple of interactive playgrounds have been developed for my parrot.

Abstract:
This project stems out of the need to improve the quality of life for both animals and humans, and facilitate the interaction between both environments into one habitat. The design will serve as a framework for the co-habitation and interaction of humans and animals in one habitat. At the core of this dissertation lies the concept of an animan habitat. This term embodies the concept of an intergrated habitat for all species. In arriving at the final design, a sequential thought process was applied. The logic behind this process will now be outlined (each corresponding section will be addressed in this document). Exploring the diversity of Architectural habitats and products has made it evident that involving Architects and Interior Architects into projects concerning animal space design can benefit wild animals and humans alike. Research into South African recreational nature spaces show the importance of the conservation of these existing spaces to different parties on local, national and international levels. The investigation of the importance of experiential nature spaces in Tshwane and the Tshwane CBDs (section 2.2.2) shows the importance and location of an establishment (the National Zoological Gardens of South Africa) with great human experiential, and animal conservation opportunities. The study of the contributions of global zoos to the world (section 2.3) confirms that any designs need to consider the principles and ethics followed by these zoos-conservation, recreation, education, experience, research, and community values. Behavioural enrichment (section 2.4) as a conservation contribution of zoos is an aspect that can be reinterpreted and incorporated into animal enclosures to enrich their environments, and further educate visitors. Studies about zoo evolutions (section 2.5) through the ages show how thoughts about captive environments are evolving. The subsequent study of exhibit design (section 2.6) makes clear the importance of considering the needs of the environment, animals, zoo occupants and visitors alike. Furthermore, research into design styles and illusions (section2.6) prove that designs (using whichever approach) should consider the wellbeing of animals before educating or entertaining humans. Design illusions could instead be used to change mans’ negative perceptions about zoos and other conserving environments. A study into design elements and principles (as studied by Ching and Miller) are currently used at the Zoo (section 2.7) to claim human and animal spaces. A variety of precedent investigations (section 3) make it clear that other institutions, zoos, reserves, bird parks, discovery centres, playgrounds, and an amphitheater, individuals (the work of Frei Otto) or companies (lightweight structure experts) offer products and techniques that could well suit animan space design. The result of the above is the cohabitation and respect for humans, animal and the environment in a bidirectional habitat. This forms the core of the animan concept and approach for the design of the Parrot Animan Precinct at the National Zoological Gardens of South Africa (Zoo). This development is a turnkey solution comprising of Site Selection and Study (section 4); Design Discourse (section 5); Technical Investigation (section 6) and Design Drawings (section 7).

Abstract:
Interactions between nesting birds and invertebrates are a common, yet poorly understood ecological phenomenon. Many of these types of interactions are close and prolonged, and therefore potentially critical to one or both of the species involved in the interaction. However it is unusual for the nature of the interaction to be evaluated in a manner that reveals the impact of the relationship on both parties to the interaction. This study examines two relationships between nesting birds and invertebrates, both of which involve the hooded parrot (Psephotus dissimilis), a small grass parrot that inhabits the tropical savannas of northern Australia. ¶ The field-work for this project was conducted over two parrot breeding seasons in 2006 and 2007 near Katherine, Northern Territory, in the Australian dry tropics. In chapter II, I present data on the breeding biology of the hooded parrot as background for the study that follows. Nest building commenced in January, with peak activity in February and the last chicks fledged in April. Fifty three active nests were located. The mean number of eggs laid per nest was 4.5 (s.d. ± 0.9), of which 3.0 (± 1.79) hatched and 2.0 (± 2.0) fledged. Clutches were laid asynchronously over a period of a week and chicks remained in eggs for 18.6 (± 1.95 days). Chicks were 29.2 (± 2.9) days old when they fledged from the nest. These data are typical for Australian parrots. ¶ In chapter III, the unusual nature of the parrot’s nest site is examined. Many species of bird nest in natural cavities or those they excavate. Whilst cavity nesters as a whole experience increased nesting success, the greatest success is experienced by species that can excavate their own nests. Certain arboreal cavity nesters, such as woodpeckers, require extensive morphological adaptation for this behaviour, but this has not occurred in Australia, despite competition among birds and a suite of arboreal mammals for naturally occurring cavities. Some species, however, have adapted their behaviour to make use of substrates that are not as hard as wood. Hooded parrots excavate nests in terrestrial termitaria, releasing them from competition for limited arboreal cavities. However, I show that only termitaria with a high level of termite activity, and which are more than two metres tall, are suitable, and that the parrots exhibit a strong preference for the cathedral mounds of Nasutitermes triodiae. Nests placed in highly active mounds had a significantly higher success rate than those in mounds where activity was somewhat lower, suggesting that the behaviour is adaptive. ¶ The thesis then shifts focus from the parrot to its nest symbiont, first describing the species involved in the interaction in chapter IV, and then its behaviour in the nests of hooded parrots in chapter V. Trisyntopa neossophila sp. n. (Lepidoptera: Oecophoridae) was reared from the nest of the hooded parrot and described using morphological characters. Aspects of its biology are reported and similarities to the biology of Trisyntopa scatophaga found in the nests of the golden-shouldered parrot (Psephotus chrysopterygius) are discussed. The possibility that a moth was associated with the extinct paradise parrot (Psephotus pulcherrimus) is considered in the light of the phylogenetic relationships between the parrots. ¶ Trisyntopa neossophila is an unusual moth whose breeding cycle is shown to be closely synchronised with the hooded parrot. T. neossophila is one of three coprophagous, nest dwelling moths in the genus Trisyntopa. True coprophagy is rare in the Lepidoptera, although some species occasionally consume faeces to gain rare nutrients. T. neossophila lays its eggs in the nest of hooded parrots so that larvae hatch in synchrony with the hatching of the parrot’s eggs. The larvae spend their larval period in the nest and exclusively consume the excrement of the nestling parrots. When the parrot chicks fledge, the larvae move to the walls of the nest cavity to pupate, emerging the following wet season to repeat the process during the next parrot breeding season. ¶ With a description of the ecology of both species involved in the nesting symbiosis, chapter VI reviews the literature surrounding other interactions between nesting birds and invertebrates. A large number of birds are shown to nest in, or in close proximity to, structures made by invertebrates and avian nesting material provides a reliable shelter for many invertebrate species. However, the nature of such relationships has rarely been experimentally demonstrated. I propose that in order to understand the nature of these relationships they need to be explored within the theoretical framework of community ecology. Putative commensal and parasitic relationships have all been documented in the bird/invertebrate nesting literature, yet researchers, with few exceptions, repeatedly overlook the impact that these relationships are having on the invertebrate, at best assuming the nature of its impact, but more often ignoring its impact entirely. Here I present a framework for formulating hypotheses to ensure that the nature of the relationship can be identified. Only by explicitly stating the level of organisation at which the experiment is to occur (individual or population), identifying the net cost or benefit of the interaction, the range of conditions under which such costs or benefits would apply and the spatial and temporal context in which they apply, can an investigator expect to recognise and describe the often complex nature of these relationships. ¶ While parasitic and commensal relationships between nesting birds and invertebrates are commonly reported, mutualisms between birds and invertebrates have not been reported. Despite this, candidates for this type of relationship exist. Chapter VII uses the framework outlined in the literature review (chapter VI) to experimentally examine the relationship between the hooded parrot and Trisyntopa neossophila. By manipulating the populations of moth larvae in a sample of hooded parrot nests, we sought to establish the impact of the relationship on each species. The moth depends on the parrot for provision of shelter and a reliable food source. The parrot however, was neither benefited nor harmed by the interaction in terms of short term reproductive output or chick growth, although differences between the experimental and control nests were noted. The relationship between the hooded parrot and T. neossophila, at least during the study period, is therefore concluded to be commensal. ¶ Collectively, the chapters of this thesis explore the complicated interactions between species. The dependence of the moth on the parrot and the parrot on the termite, demonstrate the importance of understanding interactions between species in a manner that reveals the impacts of the interactions, the range of conditions under which they would apply and the level of organisation at which they apply, as outlined in chapter VI. The dependence of the animals in this study on each other makes them more vulnerable to extinction than previously thought. Whilst this may not be immediately significant for the hooded parrot/T. neossophila system, which is thought to be secure, the ecologically similar system on the Cape York Peninsula, involving the golden-shouldered parrot and its nest attendant moth Trysintopa scatophaga, is vulnerable to extinction and subject to intensive management to ensure its persistence. This study brings new information to the management of the golden-shouldered parrots and urgently recommends increased protection for Trysintopa scatophaga.

Abstract:
Urbanisation typically results in homogenisation of the constituent avifauna, as generalists that are able to adapt to and persist within the urban landscape replace specialist species whose specific habitat needs are removed. Recently, within some major urban centres, parrots have become a conspicuous component of the avifauna, present in higher abundance in the urban landscape than in the natural environment. This thesis examines the composition and distribution of the parrot community within a large urban centre and evaluates the relative importance of key abiotic and biotic factors that may explain the increase in abundance of urban parrots. I demonstrated that parrot species were present in higher abundance within the urban landscape, compared to natural habitat and that, historically, both drought and wild fire resulted in an influx of some parrot species into the urban landscape. I demonstrated that the standing crop of nectar was consistently higher within streetscapes compared to the non-urban habitat and is capable of sustaining large populations of large-bodied nectarivores. I also demonstrated that trees within the urban landscape produce more flowers and flower for longer than the same species of tree outside the urban landscape. I showed that there were significantly more visitations to hollows by parrots within the urban landscape, compared to forest, as well as significantly more aggressive interactions. My results demonstrate that the urban landscape is capable of sustaining a diverse community of native parrots, particularly nectarivores such as the rainbow lorikeet. The urban landscape provides food resources in excess of that found in natural habitat, however nesting resources are fewer compared to natural habitat. My research suggest that there may be a shortage of tree hollows and I discuss how, if the density of parrots continues to increase, there may be a simplification in the current avifauna due to a shortage of breeding resources.

The swift parrot (Lathamus discolor, Psittacidae) is an endangered, austral migrant that inhabits forests and woodlands of south-eastern Australia. With a small population size (2500 birds), broad winter distribution (1 250 000 km2) and often cryptic nature, the swift parrot is a challenging species to study. In autumn they migrate north from their Tasmanian breeding grounds in search of suitable food resources throughout their winter range on mainland Australia. They are therefore dependent on a combination of suitable wintering, migration and breeding habitats. Although they spend a large proportion of their lives within winter habitats, the spatial and temporal dynamics of habitat use in this part of their range is poorly understood. This thesis aims to provide a greater understanding of large-scale winter habitat use by swift parrots, in both historic and current contexts, and provide a basis for future conservation management. ¶ Swift parrots, or red-shouldered paroquets as they were previously known, were among the first Australian birds to be scientifically described and illustrated following European settlement in 1788. However, within 60 years of settlement, habitats throughout the range of the species were being impacted upon. An important aspect of this habitat loss is the speed and spatial extent with which it occurred throughout the parrots’ broad distribution. Although the most extensive habitat loss in some areas occurred during colonial times, habitats continue to be lost as a result of various land management practices. Such impacts are also likely to be exacerbated by the ongoing cumulative impact with rapid climate change. As a result the swift parrot is an endangered species and is the subject of an ongoing national recovery program, to which this thesis contributes. ¶ Conserving habitat for the swift parrot, and other wide-ranging fauna species, is challenging since impacts in one area tend to be dismissed based on the assumption that there is sufficient habitat in other areas. These conservation challenges are discussed in regard to the national swift parrot recovery program. Although recovery program implementation for this species has been successful in identifying and protecting some important habitats, there are still many gaps in our knowledge that need to be addressed through a continuing and adaptive recovery effort, including an understanding of variable habitat use throughout their winter range. ¶ A study of swift parrot winter habitat use was therefore conducted at 53 sites across New South Wales over five years (2001-2005). Swift parrots used a diversity of winter foraging habitats in coastal and/or western slopes regions of New South Wales each year, including several habitats that occur in endangered ecological communities. 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 associated with the abundance of lerp, nectar and non-aggressive competitors. Although swift parrot abundance fluctuated significantly between years and regions, over half of all foraging sites were used repeatedly, highlighting their likely importance for conservation. ¶ Patterns of habitat use throughout the species’ winter range were also studied across five states/territories using volunteer data from 4140 surveys. These surveys were conducted by up to 300 volunteers twice a year, for seven years (1998-2004) with swift parrots detected in 19% of surveys. As a result, this study provided the first demonstration of large-scale drought related movements by a migratory population throughout their winter range. It also demonstrated the dynamic spatial and temporal patterns of winter habitat use, including repeated use of sites, by an austral migrant. Four regions in central Victoria were used most consistently, although the birds also visited other regions each year. ¶ During drought swift parrot abundance was significantly correlated with rainfall, whereby most of the population either concentrated in a few regions or migrated longer distances (up to 1000km) to drought refuges in wetter coastal areas. However, swift parrot abundance was not associated with specific climate variables during years of average to high rainfall throughout most of their range. Instead they appeared to prefer habitats within particular regions. Importantly this study emphasises that conservation measures need to be implemented throughout the distribution of migratory species, including drought refuge habitats and areas outside conservation reserves.

Abstract:
This paper presents novel evidence of an intervention to foster preschool students cognitive skills during COVID-19 pandemic. We conducted a policy experiment that provided preschool student parents with a SMS text message program to support student learning at home. Taking advantage of existing parent networks, we study the direct effect of being selected to receive the SMS text messages, and the spillovers of being part of a parent network. We show that after 15 weeks of intervention, SMS text messages increase student cognitive skills by 0.11 to 0.12 standard deviations. The effect is driven by an increase of parental involvement through the proposed activities. We find no evidence that information is transferred within parent networks.
