Diet to tissue discrimination factors for the blood and feathers of the monk parakeet (Myiopsitta monachus) and the ring-necked parakeet (Psittacula krameri) [PDF]
Animal Biodiversity and Conservation, 2019 Stable isotope analyses (SIAs) have been widely used in recent years to infer the diet of many species. This isotopic approach requires using diet to tissue discrimination factors (DTDFs) for each prey type and predator tissue, i.e., to determine the ...

Not in the countryside please! Investigating UK residents’ perceptions of an introduced species, the ring-necked parakeet (Psittacula krameri) [PDF]
NeoBiota, 2023 Wildlife management can generate social conflict when stakeholder perceptions of the target species are not considered. Introduced Ring-necked Parakeets (RNP) are established in the UK and have been added to the ‘general licence’ of birds that can be ...

Cranial integration in the ring-necked parakeet, Psittacula krameri (Psittaciformes: Psittaculidae) [PDF]
Biological Journal of the Linnean Society, 2021 Abstract The study of integration and modularity aims to describe the organization of components that make up organisms, and the evolutionary, developmental and functional relationships among them. Both have been studied at the interspecific (evolutionary) and intraspecific (phenotypic and ontogenetic) levels to different degrees across ...

Leaf bathing in ring-necked parakeets Psittacula krameri [PDF]
Arxius de Miscel·lània Zoològica, 2021 Bathing is one of the main actions birds perform as part of their preening. They may bathe in water, snow, dust, and even ants. Leaf bathing, where birds make use of water droplets on leaves to bathe, is less common. Here we describe four observations between 2017 and 2021 of ring-necked parakeets Psittacula krameri bathing on water droplets on leaves ...

Understanding the origins of the ring‐necked parakeet in the UK [PDF]
Journal of Zoology, 2019 AbstractThe ring‐necked parakeet Psittacula krameri is one of the best‐known invasive species in the UK. It is also arguably the species whose origins as an invasive have been the subject of the greatest speculation, with explanations ranging from birds escaping from the set of the film ‘The African Queen’ to animals being released in Carnaby Street in

Microsatellite characterisation and sex-typing in two invasive parakeet species, the monk parakeet Myiopsitta monachus and ring-necked parakeet Psittacula krameri [PDF]
Molecular Biology Reports, 2019 AbstractInvasive species can have wide-ranging negative impacts, and an understanding of the process and success of invasions can be vital to determine management strategies, mitigate impacts and predict range expansions of such species. Monk parakeets (Myiopsitta monachus) and ring-necked parakeets (Psittacula krameri) are both widespread invasive ...
