Establishment success of invasive ring-necked and monk parakeets in Europe
Journal of Biogeography, 2009AbstractAim Invasive alien species are a growing threat to biodiversity, and identifying the mechanisms that enable these species to establish viable populations in their new environment is paramount for management of the problems they pose. Using an unusually large number of both failed and successful documented introductions of parakeets (Aves ...

‘The early bird catches the nest’: possible competition between scops owls and ring-necked parakeets [PDF]
Animal Conservation, 2017 AbstractCompetition for critical resources is one of the key mechanisms through which invasive species impact on native communities. Among birds, the widely introduced ring‐necked parakeet Psittacula krameri locally affects cavity‐nesting communities through competition for suitable tree cavities, although it remains unclear to what extent such ...

Nestling Development of Ring-necked Parakeets (Psittacula krameri) in a Nest Box Population [PDF]
Open Ornithology Journal, 2013 Chick development of a population of non-native Ring-necked Parakeets (Psittacula krameri) (RNP) has been investigated between 2006 and 2008 in Heidelberg, Germany. In parrots hatching asynchrony is common. RNP chicks are under natural selection to fledge synchronously with their siblings, as parents return less often to the nest after the first chick ...

Biological Invasions, 2017
Climate similarity favors biological invasion, but a match between seasonality in the novel range and the timing of life cycle events of the invader also influences the outcome of species introduction. Yet, phenology effects on invasion success have generally been neglected. Here we study whether a phenological mismatch limits the non-native range of a

Invasive Ring-Necked Parakeet Negatively Affects Indigenous Eurasian Hoopoe
Annales Zoologici Fennici, 2016The ring-necked parakeet invaded southern Israel and competes with indigenous cavity-nesting species for nest sites. However, the parakeet can also excavate its own cavities, providing other birds with breeding places, so the final impact on native avifauna is questionable.

Foot preferences in wild-living ring-necked parakeets (Psittacula krameri, Psittacidae)
Laterality: Asymmetries of Body, Brain and Cognition, 2011Evidence for foot preferences has been reported in parrots and the majority of parrot species uses the left foot to hold and process food objects. Here we assessed the footedness of ring-necked parakeets (Psittacula krameri) in a wild-living non-native population in Heidelberg, Baden-Wurttemberg, Germany.

CHLAMYDIA AVIUM DETECTION FROM A RING-NECKED PARAKEET ( PSITTACULA KRAMERI ) IN FRANCE
Journal of Exotic Pet Medicine, 2018Abstract The crossing of host species barriers, through the spreading populations of introduced pet animals that become established in the wild, sets the stage for zoonotic pathogen (re)emergence. A literature review on pathogens that are hosted by the ring-necked parakeet ( Psittacula krameri ), a worldwide introduced pet, highlighted local ...

Effects of the Recent World Invasion by Ring-Necked Parakeets Psittacula krameri
2015Over 60 out of 355 currently living parrot species have established at least one breeding population outside their natural distribution ranges. Among those, the ring-necked parakeet is one of the most successful invaders. This species is a gregarious Afro-Asian parakeet with an extremely large distribution range, recorded in over 35 countries outside ...
