Gross anatomy of some digestive organs of the domestic canary ( Serinuscanarià )

Abstract

PURPOSE: The domestic canary (Serinus canariа) is a widely spread representative of the largest avian order Passeriformis. The increased interest to canaries as pets, the scarce anatomical data and the frequently encountered digestive tract pathology are the motives of the present study. The purpose of the research was to investigate the normal anatomy and topography of some digestive organs of the domestic canary. MATERIALS AND METHODS: The corpses of 12 canaries at 2 years of age were investigated. The bodies were divided into 2 groups of 6 birds each. The birds from group I were dissected and anatomo-topographic features of some digestive organs were examined in situ. The obtained data were used in bodies from group II for determination of percutaneous anatomic projections of the gizzard, duodenum, ileum and the liver. The sternal margo caudalis, last pair of ribs and os pubis were used as bone markers for more precise projections. After determination of percutaneous projections of organs, the bodies of canaries from group II were subjected to dissection for comparison of anatomical findings. RESULTS: The anatomo-topographic features of some digestive organs of the domestic canary and associated normal anatomic percutaneous projections were determined and documented. CONCLUSION: The results could serve for macroscopic in vivo and pathoanatomical diagnostic studies, as well as for prophylaxis of digestive organs’ illnesses
