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

Infectious agents present in monk parakeet (Myiopsitta monachus) and rose-ringed parakeet (Psittacula krameri) invasive species in the parks of Madrid and Seville, Spain [PDF]
Frontiers in Veterinary Science, 2023 IntroductionThe introduction of invasive species into an ecosystem could result in biodiversity loss and the spread of infectious agents that could cause re-emergent or emergent zoonotic diseases.

Evidence for vocal signatures and voice-prints in a wild parrot [PDF]
Royal Society Open Science, 2023 In humans, identity is partly encoded in a voice-print that is carried across multiple vocalizations. Other species also signal vocal identity in calls, such as shown in the contact call of parrots.

Novel food resources and conservation of ecological interactions between the Andean Araucaria and the Austral parakeet [PDF]
Ecology and Evolution, 2022 In fragile ecosystems, the introduction of exotic species could alter some ecological processes. The Austral parakeet (Enicognathus ferrugineous) shows close ecological and evolutionary relationships with the Andean Araucaria (Araucaria araucana), so any

Multi-layer networks reveal changes in plant-bird interactions driven by invasive species [PDF]
Communications BiologyBiological invasions can strongly disrupt ecosystems, reshaping their structure and functioning. We investigate how two widespread invasive parrots –the rose-ringed parakeet Psittacula krameri and the monk parakeet Myiopsitta monachus- affect plant-bird ...

Temporary Behavioral Responses to Playbacks by a Pest Parrot and Implications for Management [PDF]
Animal Behavior and Cognition, 2022 Human-wildlife interactions continue to increase due to anthropogenic disturbances, with some interactions resulting in conflict. Leveraging a taxa’s bias for a particular sensory cue is a promising management avenue for reducing the potential and ...

Birds, 2022 Monk Parakeets are considered one of the most invasive bird species given its unique capacity among psittacines to build their own communal nests. Originally introduced as pets in houses from where they escaped or were released, they are currently ...

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.

BMC Zoology, 2021 Background The Orange-fronted Parakeet (Eupsittula canicularis) is the Mexican psittacine that is most captured for the illegal pet trade. However, as for most wildlife exploited by illegal trade, the genetic diversity that is extracted from species and ...

An overlooked plant–parakeet mutualism counteracts human overharvesting on an endangered tree [PDF]
Royal Society Open Science, 2018 The exponential growth of the human population often causes the overexploitation of resources and disruption of ecological interactions. Here, we propose that the antagonist effect of humans on exploited species might be alleviated with the advent of a ...
