ABSTRACT

The aim of this study is to morphologically describe the lungs and air sac system in Rosy-faced parrots (Agapornis roseicollis) and provide useful data for future veterinary care and treatment of respiratory system disease in these pets. The research was conducted on five birds. In order to obtain the casts of the lungs and air sacs, we applied the corrosion cast technique, where we used the 26% solution of Vinylite mass. The research showed that the basic anatomy of the lungs and air sacs in these parrots was very similar to that in other birds, but there is some specific characteristic regarding onto the arrangement and connection between the air sacs. In Rosy-faced parrots we identified a nine air sacs, the one upaired, saccus clavicularis and paired saccus cervicalis, thoracicus cranialis, thoracicus caudalis and abdominalis. Also, we recorded that clavicular and cranial thoracic air sacs establish a connection through the diverticula sternalia, what can be common to birds from Psittaciformes order.
