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.

Invasion success of a global avian invader is explained by within-taxon niche structure and association with humans in the native range [PDF]

, 2015
Aim To mitigate the threat invasive species pose to ecosystem functioning, reli- able risk assessment is paramount. Spatially explicit predictions of invasion risk obtained through bioclimatic envelope models calibrated with native species distribution ...

Dimorfismo sexual da traquéia e siringe de periquito (Touist sp.) Sexual dimorphism of the parakeet (Touist sp.) trachea and syrinx

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2007
Investigaram-se as diferenças morfológicas da siringe do periquito Touist sp, cinco machos e cinco fêmeas. A traquéia e a siringe foram dissecadas com o auxílio de uma lupa estereoscópia e avaliaram-se o número de anéis, o comprimento da traquéia e da ...

Effects of cold winters and roost site stability on population development of non-native Asian ring-necked parakeets (Alexandrinus manillensis) in temperate Central Europe – Results of a 16-year census [PDF]

, 2018
Asian ring-necked parakeets (Alexandrinus manillensis, formerly Psittacula krameri, hereafter RNP) first bred in Germany in 1969. Since then, RNP numbers increased in all three major German subpopulations (Rhineland, Rhine-Main, Rhine-Neckar ...
