The purpose of this study was to have a general view of pancreas in one species of pigeon.Some disorders affect avian pancreas.Pancreatitis and Pancreatic degeneration have been described in many infections and deficiencies. In pigeon, lymphoid infiltration and necrosis diffusion is a common finding. After anesthesia, tissue pieces were dissected from the lobes. Samples were fixed in Bouin, processed and stained by H&E and Gomori for light microscopy study. The pancreas of this pigeon had four lobes. The acini had oval shape with centroacinar cell. Ducts had simple to stratified cuboidal epithelium and muscular layers were around of ducts.Isletsare more numerous in ventral part of lobe B and in dorsal part of lobe A.The spleen segment in this pigeon contained fewer islets than the rest of the pancreas.The cells of islets in this species of pigeon were not distributed evenly throughout each islet.There were B cell and a few D cells inside light B islets andthere were A cell and a few D cells inside dark A islets.There were some similarities and differences in pancreas of this species to other birds.
