'Some like it alien': predation on invasive ring–necked parakeets by the long–eared owl in an urban area [PDF]

Animal Biodiversity and Conservation, 2020
Predation pressure by native species may limit the spread of alien invasive species, thus playing a pivotal role in the impact and implementation of management strategies. The ring–necked parakeet Psittacula krameri is one of the most widespread alien bird species in Europe, with nearly 70 established populations.

A Cross‐Sectional Study on Parakeets Feeding and Housing Practices in Italy

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Italy has one of the largest companion bird populations in Europe. This study aimed to investigate feeding and housing practices among Italian parakeet owners. An online questionnaire was distributed, yielding 433 voluntary responses. Participants were classified as hobbyists (HBY; ≤ 13 birds owned) or breeders (BRD; > 13 birds owned) to ...

Preventing Invasive Non‐Native Species: A Horizon Scanning for the Canary Islands

Diversity and Distributions, Volume 32, Issue 10, October 2026.
ABSTRACT Aim Oceanic islands host exceptional biodiversity and endemism but are highly vulnerable to biological invasions. We aimed to identify non‐native species with high potential to invade the Canary Islands within the next decade and to prioritise them based on their environmental and socioeconomic risks.

The Legal International Wildlife Trade Favours Invasive Species Establishment: The Monk and Ring-Necked Parakeets in Spain [PDF]

Ardeola, 2018
The international wildlife trade is a lucrative business. Although a huge variety of animal groups are trafficked, the Psittaciformes (parrots) are amongst the most traded avian groups. Deliberate or accidental releases of imported parrots have led to the establishment of feral populations in many countries.

Invasive mammals disrupt sea–land nutrient inputs over 169 years on subtropical oceanic islands

Ecosphere, Volume 17, Issue 9, September 2026.
Abstract Invasive mammals have severely impacted oceanic islands, reducing or extirpating seabird populations and driving the collapse of nutrient flows with lasting ecosystem effects. We investigated these dynamics on contrasting subtropical oceanic islands in the South Pacific: Rangitāhua, a large island where goats, cats, and rats caused the ...

Assessment of reproductive parameters of privately bred ring-necked parakeets (Psittacula krameri)

Roczniki Naukowe Polskiego Towarzystwa Zootechnicznego, 2019
The aim of this study was to assess the reproductive parameters of privately bred ring-necked parakeets (Psittacula krameri). The study was carried out in an amateur breeding facility in the Masovian voivodeship in 2013–2017. Observations were carried out on four pairs of ring-necked parakeets kept year round in outdoor aviaries. The analysis was based

Worldwide distribution of non–native Amazon parrots and temporal trends of their global trade [PDF]

Animal Biodiversity and Conservation, 2017
Alien species are the second leading cause of the global biodiversity crisis, after habitat loss and fragmentation. Popular pet species, such as parrots and parakeets (Aves, Psittaciformes), are often introduced outside their native range as a result of ...

Attitudes to Exotic Parakeets: A Comparative Case Study and Citizen Science Review

Diversity
Invasive, non-native species are recognised as a global problem, and their dispersal and introduction are controversial topics. However, a source of particular interest is that of human–nature interactions and consequent perceptions of natives and non ...
