Appendicular Skeleton of Rose-Ringed Parakeet (Psittacula krameri): Influence of age, gender and breeding season

Abstract

The present project was designed to study and compare different parameters of the forelimb and hind limb bones in juvenile, adult male and female rose-ringed parakeet in breeding and non-breeding seasons. For morphometric measurement, the forelimb and hind limb bones of juvenile and adult parrots (male = 9, female= 9) were collected in breeding and non-breeding seasons after autopsy. - The data was computed with Microsoft excel® and statistically analyzed using Minitab software. The groups were compared using Tukey’s honestly significant difference test. - The results showed the measurements of breeding season female bones were slightly larger in size than the bones of non-breeding season female and juvenile female. Moreover, breeding season male showed slightly larger values than the bones of non-breeding-season male and juvenile groups. Hence, the current study provided novel information about the comparative morpho-functional features and detailed description along with illustration of forelimb and hind limb bones of a juvenile, adult male, and a female rose-ringed parakeets in breeding and non-breeding seasons.
