Presence of the alien Rose-ringed Parakeet Psittacula krameri (Psittacidae) in Mozambique
Ostrich, 2023The 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, we bring attention to recent sightings of the species in Mozambique and the possibility

Acute, fatal Sarcocystis falcatula infection in rose-ringed parakeets (Psittacula krameri)
Veterinary Parasitology: Regional Studies and Reports, 2023Sarcocystosis is an important avian disease that affects several intermediate host species. Birds not endemic from Americas, like Old World psittacine species, appear to be more susceptible to lethal infection than New World psittacine species. The aim of this study was to investigate the sudden death of rose-ringed parakeets (Psittacula krameri) in an

Primary structure of the hemolglobin β-chain of Rose-ringed Parakeet (Psittacula krameri)
Journal of Protein Chemistry, 1989The primary structure of Rose-ringed Parakeet hemoglobin beta-chain was established, completing the analysis of this hemoglobin. Comparison with other avian beta-chains show variations smaller than those for the corresponding alpha-chains. There are 11 amino acid exchanges in relationship to the only other characterized psittaciform beta-chain, and a ...

Primary structure of the hemoglobin α-chain of rose-ringed parakeet (Psittacula krameri)
Journal of Protein Chemistry, 1988The structure of the hemoglobin alpha-chain of Rose-ringed Parakeet was determined by sequence degradations of the intact subunit, the CNBr fragments, and peptides obtained by digestion with staphylococcal Glu-specific protease and trypsin. Using this analysis, the complete alpha-chain structure of 21 avian species is known, permitting comparisons of ...

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 ...

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.

Elemental Analysis of Various Feathers of Indian Rose Ringed Parakeet Psittacula krameri
2016The plumage coloration is a costly phenomenon adapted by birds. In birds, coloration can occur either by pigmentation or structural variation. The feather coloration helps to find partner and protect from predators. A few birds adapted cosmetic coloration, to protect themselves from the predators either by gland secretion or by accumulating certain ...

A case report of vascular hamartoma in a rose-ringed parakeet (Psittacula krameri)
Journal of Poultry Sciences and Avian DiseasesVascular hamartomas, though rare, can manifest in avian species, presenting diagnostic intricacies for clinicians. A 12-year-old male rose-ringed parakeet presented with a mass between the upper and lower mandibular angles on the left side. The mass was surgically removed.
