Eight mallards (five female, three male) weighing 1244±114 g were examined. It was observed that the syrinx in mallard was tracheabronchial type formed by tympanum, cartilagines tracheosyringeales and cartilagines bronchosyringeales. Tympanum and cartilagines tracheosyringeales were formed from four and six cartilage rings, respectively, while cartilagines bronchosyringeales was formed from C-shaped cartilage rings. It was found that pessulus was contained ossified tissue partially and was extended into cavum syrinx as wedge-shaped. It was determined that syrinx in male ducks was found to be asymmetrical and had a large expansion on the left side called bulla tympaniformis. The right and left bronchus primarius were bound together by a tight ligamentum interbronchiale. Membrana tympaniformis medialis was extending from pessulus to the 3th cartilago. bronchosyringealis ring. Membrana tympaniformis lateralis was found to be between the last tympanum ring and the 1st cart. bronchosyringealis ring. Histological examinations of both pesulus as well as syrinx partially ossified structure were determined.}, number={2}, publisher={Harran University}
