Macroanatomic Examination of the Trachea and Syrinx in Budgerigars and Canaries

The purpose of the present study is to examine and compare the trachea and larynx caudalis of budgerigars and canaries in a macroanatomic manner. 18 canaries and 29 budgerigars that were collected as dead from the clinics of the surrounding area were used in this study. The number of cartilago trachea was 46-47 in canaries; and 53-61 in budgerigars. Crossman’s Triple Staining Method was used for histological examinations. 0.1% methylene blue solution was used to examine in a stereo microscope. Tracheobronchial-type syrinx was observed in both species. In canaries last 4-5 trachea rings were joined together to form the tympanum. It was observed that in all species the trachea rings were full. The ligamentum annulare and musculus trachealis were not observed in both species. While pessulus and tympanum were observed in canaries, they were not detected in budgerigars. Musculi syringeales was detected in budgerigars in an extremely developed structure. Cartilagines bronchosyringeales formed the last part of the syrinx; and it consisted 8-9 cartilages in canaries and 6-7 cartilages in budgerigars.
