The Ouvéa Parakeet (Eunymphicus uvaeensis), endemic to Ouvéa Island (Loyalty Islands, New Caledonia, south-west Pacific), is a rainforest bird that is dependent on tree cavities for nesting. It is threatened by deforestation, but also by competition for nest sites with introduced bees, harvesting for pets, and potentially predation by introduced species. Despite these threats, we show that the Ouvéa Parakeet population increased exponentially from an estimated 617 (274–996) birds in 1993 to 2… Expand

Using ecological niche models to infer the distribution and population size of parakeets in New Caledonia
Knowing the distribution and abundance of species is critical for conservation, yet field surveys are often limited in their spatial extent. In this study, we use ecological niche models to infer theExpand
Parrots of Oceania – a comparative study of extinction risk
ABSTRACT Australia, New Zealand, New Guinea, Wallacea, and the islands of the Pacific Ocean collectively possess 42% of the world’s parrot species, including half of all Critically EndangeredExpand
Experimental test of a conservation intervention for a highly threatened waterbird.
TLDR
Comparison with other studies suggests that nest guarding effectiveness may be context-specific and differ between species that are exploited opportunistically, such as white-shouldered ibis, and those routinely targeted for trade. Expand
Large-scale habitat selection by parrots in New Caledonia
TLDR
It is considered rainforests on oligotrophic soils at intermediate altitudes at 200–800 m to be most important for parrot conservation in New Caledonia, as these habitats are likely to support significant parakeet populations. Expand
Positive range–abundance relationships in Indo‐Pacific bird communities
TLDR
Clear evidence is found that range–abundance relationships are positive and endemic species have narrower habitat niches than wide-range species in New Caledonia. Expand
Using Species Distribution Model to Estimate the Wintering Population Size of the Endangered Scaly-Sided Merganser in China
TLDR
The entire wintering population of Scaly-sided Merganser in China is estimated to be 3,561 ± 478 individuals, which is consistent with estimate in its breeding ground, and area under the receiver operating characteristic curve (AUC) method suggests high predictive power of the model. Expand
Temporal Variation in Flock Size and Habitat Use of Parrots in New Caledonia
TLDR
It is suggested that the observed difference in habitat use between the New Caledonian Parakeet and Horned Parakeets is the result of spatial resource partitioning, which allows these closely related species to coexist. Expand
Preliminary surveillance for beak and feather disease virus in wild parrots of New Caledonia: implications of a reservoir species for Ouvea Parakeets
TLDR
Findings from a survey in 2012 are presented to investigate the presence of BFDV in wild New Caledonian parrots, including the endangered Ouvea Parakeet, suggesting this species may act as a reservoir for persistence of B FDV in the wild, placing other parrots in NewCaledonia at risk. Expand
Analysis of Genetic Diversity and Evolution through Recombination of Beak and Feather Disease Virus
TLDR
This study provides evidence that more than one strain of BFDV is present in New Zealand, and highlights the need for continuous screening of both wild and captive birds, in order to limit the risk of transmission to New Zealand’s other endangered parrots. Expand
Standardising distance sampling surveys of parrots in New Caledonia
Standardised surveys are essential for moni- toring populations and identifying areas that are critical for conservation. With the aim of developing a standardised method of surveying parrots in theExpand

Population Estimate for the Ouvea Parakeet Eunymphicus cornutus uvaeensis: Its Present Range and Implications for Conservation
TLDR
A population count using fixed distance line transects was made in December 1993 during the breeding season to estimate the minimum size of the population, its distribution in the island of Ouvea and to emiphasise threats to its survival in order to plan a conservation program. Expand
The Ouvéa parakeet - state of knowledge and conservation status
TLDR
New Caledonia, a French territory in the south-west Pacific has a very high number of endemic taxa, including a monotypic genus of parakeets Eunymphicus, which is seriously threatened by degradation of its natural habitat, natural predators and capture for sale to collectors. Expand
Threats on Pacific islands: the spread of the Tramp Ant Wasmannia auropunctata (Hymenoptera: Formicidae)
TLDR
Invasions are not an abnormality in the evolutionary process, but an increase in their rate could lead to a dramatic homogenization of fauna and flora. Expand
Nest Poaching in Neotropical Parrots
Although the poaching of nestlings for the pet trade is thought to contribute to the decline of many species of parrots, its effects have been poorly demonstrated. We calculated rates of mortalityExpand
Impact of protection on nest take and nesting success of parrots in Africa, Asia and Australasia
TLDR
The results corroborate those for the Neotropics and suggest that conservation of parrots globally would benefit from similar legislation introduced in other regions, such as the EU, which is responsible for more than 60% of global imports of wild parrots. Expand
Ecology and Management of Nesting Blue-and-Yellow Macaws (Ara ararauna) in Mauritia Palm Swamps
TLDR
The data presented here suggest that cutting five palms a year in perpetuity would produce a stand of approximately 20 standing dead palms used by 6 or more pairs of macaws annually, however, macaw occupancy rates would depend on the density of macaw and density of naturally occurring nest sites.

Morphological, behavioural and genetic differentiation within the Horned Parakeet (Eunymphicus cornutus) and its affinities to Cyanoramphus and Prosopeia
TLDR
From genetic, behavioural and morphological data, the two Eunymphicus taxa should be considered separate species, a suggestion that is supported by ecological data as well as anecdotal data on hybridisation from captive birds. Expand
Cooperative breeding, mate guarding, and nest sharing in two parrot species of New Caledonia
TLDR
Evidence for cooperative breeding in two endemic parrot species of New Caledonia, the NewCaledonian Parakeets and the Horned Parakeet, is provided and genetic analyses showed that males shared paternity. Expand

TLDR
Considering the dramatic and well known effects resulting from the introduction of rat species such as R. rattus and R. norvegicus on small Pacific Island environments, the authors have alerted local authorities and the population of Ouvea, and have proposed initial measures as part of an action plan.
