‘Some like it alien’: predation on invasive ring-necked parakeets by the long-eared owl in an urban area

Animal Biodiversity and Conservation, 2020
El gusto por lo exótico: la depredación de la cotorra de Kramer invasora por el búho chico en una zona urbana La presión predatoria que ejercen las especies nativas puede limitar la propagación de especies invasoras exóticas y, en consecuencia, tener ...

Snowmelt predicts earlier breeding across the latitudinal range of an Arctic nesting seabird, the Little Auk (Alle alle)

Journal of Animal Ecology, EarlyView.
Multi‐year monitoring of the crevice‐nesting High Arctic seabird, the Little Auk (Alle alle), across four colonies spanning distinct climatic regimes revealed that snowmelt timing is a key and consistent driver of breeding phenology. Earlier snowmelt advances access to nesting habitat, enabling birds to initiate reproduction sooner. These findings show

Fatal dual infection of avian polyomavirus and psittacine beak and feather disease virus in Chile

Austral Journal of Veterinary Sciences, 2017
A 6 week old Plum-headed parakeet (Psittacula cyanocephala) from a private bird collection in the Metropolitan Region of Chile died after presenting depression, ataxia, tremors of the head, subcutaneous hemorrhage and delayed crop emptying.

Studies on the Rose-ringed Parakeet Psittacula krameri colony of Genoa (Liguria, NW Italy)

Avocetta, 2022
Taking into account that the previous quantitative data relating to the Rose-ringed Parakeet Psittacula krameri of Genoa (Liguria, Italy) dates back to 2009 and considering the potential impact that an alien species can have on native ones and the ...

A Multispecies Systematic and Critical Review of Intranasal Administration in Veterinary Anaesthesia and Emergency Care: Promising Evidence and Overlooked Challenges

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
This review evaluates the clinical potential and limitations of intranasal (IN) drug administration in veterinary anaesthesia and emergency care. IN delivery can provide clinically relevant sedation, analgesia and drug reversal, but its success is not universally reliable and is strongly influenced by species‐specific anatomy, formulation ...

Non‐native parrot species expand the trait space of avian communities by filling empty niches in urban areas

Ibis, Volume 168, Issue 3, Page 1055-1070, July 2026.
Non‐native species are one of the greatest threats to biodiversity worldwide due to their direct and indirect effects on native communities. There are two opposing hypotheses to explain how non‐native species successfully establish outside their native range.

Presence of the alien rose-ringed parakeet Psittacula krameri (Psittacidae) in Mozambique

, 2023
The biology of the Rose-ringed Parakeet Psittacula krameri has been widely studied in many of its naturalized habitats around the world. However, its potential status and impacts may have gone unnoticed in regions with limited monitoring. In this report,

Balancing conflict and coexistence: Interactions between invasive monk parakeets and native urban birds

Ecological Applications, Volume 36, Issue 4, June 2026.
Abstract Biological invasions often generate complex ecological paradoxes, particularly when invasive species act as ecosystem engineers that simultaneously compete with and benefit native communities. Understanding these dual dynamics is critical for managing urban biodiversity.

Beyond species loss: Community reshuffling shapes biodiversity along the urban–rural gradient

Journal of Applied Ecology, Volume 63, Issue 6, June 2026.
Our results indicate that species turnover is a general ecological mechanism shaping vertebrate communities along the urban gradient, driven by taxon‐ and species‐specific responses to environmental and spatial features. Community differences primarily reflect habitat suitability rather than dispersal limitation, highlighting the potential of targeted ...
