Bird feeders may sustain feral Rose‐ringed parakeets Psittacula krameri in temperate Europe [PDF]

open access: yesWildlife Biology, 2011
Abstract The Rose‐ringed parakeet Psittacula krameri, a bird species of subtropical origin, has established feral populations in temperate Europe. We analysed the feeding habits of Rose‐ringed parakeets near Paris, France, in order to assess if food provided by humans might contribute to the success of this invasive bird species.

Testing multiple pathways for impacts of the non-native Black-headed Weaver Ploceus melanocephalus on native birds in Iberia in the early phase of invasion [PDF]

open access: yes, 2014
Not all non-native species have strong negative impacts on native species. It is desirable to assess whether a non-native species will have a negative impact at an early stage in the invasion process, when management options such as eradication are still
