Seasonal effects on the thermoregulation of invasive rose-ringed parakeets (Psittacula krameri)
Journal of Thermal Biology, 2013Abstract Invasive species are a major threat to global biodiversity. Rose-ringed parakeets Psittacula krameri are widely established outside their native range and are successful invaders in many countries, including South Africa. Physiological and behavioral responses to environmental conditions are considered to be major factors that influence ...

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.

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 ...

Anatomischer Anzeiger, 1976
Anatomy, histology and innervation of the heart of the rose ringed parakeet, Psittacula krameri have been studied in the present investigation. The sinuatrial node is found to be well-developed. It is located towards the right side of the cephalic end of the interatrial septum and composed of a few nucleated cells and a large fibrous mass.
