Abstract : Birds have 27 orders and about 7800 species. Waterfowl, a bird with long or very long legs, long wings that are usually pointed and angled, and a long, slender beak that may be straight or curved. The aim of this study was to eva‎luate the histomorphology of liver and gallbladder in waterfowl compared with domestic duck. Pheasants are waterfowl of the Abchilkan group. As we know, the importance of the liver and gallbladder in the human body, animals and birds, both domestic and wild, has not been hidden from anyone for years. For research operations, 10 adult male and female birds were randomly prepared and licensed from Sari city and studied morphology. From all of them, tissue samples were taken and after preparation, by normal method and laboratory staining with hematoxin and eosin (H&E).Macroscopic results obtained from these birds show the following. The average width of the right lobe of the liver in sampled birds is 6.05 mm and its length is 15.59 mm. Also, the average width and length of the left lobe of the liver of these birds were 10.81 and 19.34 mm, respectively. Also, the average width of gallbladder in sampled birds was 3.21 mm and its length was 52.08 mm. have been. Also, the average width of the right lobe of the liver in sample ducks in terms of mm is equal to 31.96 and its length is equal to 66.04 mm. Also, the average width and length of the left lobe of the liver of these ducks were 41.14 and 36.38 mm, respectively. Finally, by comparing the measurements, it can be said that the average length and width of both the left and right lobes of ducks is greater than that of waterfowl. Also, according to the obtained coefficient of importance, which is less than 0.05, this difference is significant.
