The present study include eleven of the Pied Kingfisher (Ceryle rudis) birds from both sex, the weight and length of body were (98 ± 6.901gm), (32 ± 0.524 cm) respectively. The trachea characterized by a long flexible tube (6.34 ± 0.26 cm) in length and this refer to (49.403%) from the ratio length of respiratory system. It was mostly extend along the right side of the neck ventral to the esophagus and then enter the coelomic cavity. The trachea extend rostrally from the caudal end of the cricoid cartilage of the larynx into the connection between the trachea and syrinx (First tracheosyringeal cartilage ) caudally. The weight of trachea was (0.152 ± 0.018 gm) and this refer to (9.331%) from the weight of respiratory system. The cartilage rings which forming the trachea was oval in shaped and form the basic unit structure of the trachea. The total number of tracheal cartilage rings was (64.2 ± 1.2) and the diameter of the cartilage rings unequal and show a gradual decrease of its connection of the larynx into the syrinx and the mean of perimeter of the trachea connection with larynx was (43.252 ± 1.911 mm), while the connection with syrinx was (22.915 ± 1.152 mm). It can be see two skeletal muscles connected with trachea were trachiolateralis and sternotrachealis muscles.
