Feeding ecology of the Green-cheeked Parakeet, Pyrrhura molinae (Psittaciformes, Psittacidae), in a subtropical forest of Argentina [PDF]

Neotropical Biology and Conservation, 2021
Although there are studies on certain aspects of the feeding ecology of several species of Neotropical parrots, there is scarce ecological information about Pyrrhura molinae – a Psittacidae species which is widely distributed in South America and ...

The prevalence of Trichomonas gallinae in budgerigars (Melopsittacus undulatus) in a Veterinary Clinic in Vienna between 2000-2019

Veterinární Medicína, 2021
The aim of this clinical retrospective study was to analyse the prevalence of Trichomonas gallinae in budgerigars (Melopsittacus undulatus). The role of T. gallinae in budgerigars as the cause of a typical clinical picture (young vomiting budgerigars) is

How far will they go? Considerations on the potential expansion of the Ring-necked Parakeet (Psittacula krameri) and Monk Parakeet (Myiopsitta monachus) in Veneto region (Italy) with MaxEnt distribution models

Journal of Biological Research, 2022
Predictive models of species distribution, including several parakeets, may be very useful for understanding the actual and potential distribution of alien species. The Ring-necked Parakeet and the Monk Parakeet are two alien species found in the Veneto

Diet to tissue discrimination factors for the blood and feathers of the monk parakeet (Myiopsitta monachus) and the ring-necked parakeet (Psittacula krameri)

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 ...

Annual Censuses and Citizen Science Data Show Rapid Population Increases and Range Expansion of Invasive Rose-Ringed and Monk Parakeets in Seville, Spain

Animals, 2022
Population changes of invasive species can go unnoticed long before population explosions, so long-term monitoring programs are needed to assess changes in population size.

The Role of Monk Parakeets as Nest-Site Facilitators in Their Native and Invaded Areas

Biology, 2021
While most of the knowledge on invasive species focuses on their impacts, little is known about their potential positive effects on other species. Invasive ecosystem engineers can disrupt recipient environments; however, they may also facilitate access ...

First record of Ornithonyssus bursa (Berlese, 1888) (Mesostigmata: Macronyssidae) parasitizing invasive monk parakeets in Santiago, Chile

Revista Brasileira de Parasitologia Veterinária, 2021
Myiopsitta monachus is an invasive psittacine with wide distribution due to the pet trade. Its large communal nests and synanthropic nature contribute to its successful colonization of cities, from where it seems to be expanding in range and numbers ...

A novel parakeet‐selective feeder for control of invasive psittacines

Wildlife Society Bulletin, 2023
Over 40 species of parrots, members of order Psittaciformes, have established nonnative populations globally. Monk parakeets (Myiopsitta monachus) are among the most invasive bird species worldwide.
