The purpose of this study is to characterize the histological and immunohistochemical features of endocrine pancreas of common quail (Coturnixcoturnix).Small pieces of tissue from ten apparently healthy adult quail males pancreaseswere dissected after slaughtered. Sections were stained with Gomorra’s method stain for distinguish pancreatic islets .Sections were also processed for standard immunohistochemistry techniques using polyclonal primary and secondary antibodies for glucagon and insulin hormones .The histological examination showed three types were identified: alphais lets were mainly composed of alpha and delta cells, beta islets were mainly composed of beta and delta cells and mixed is lets were mainly composed of alpha, beta and delta cells. Furthermore alpha cells were round, oval or columnar in shape, beta cells appeared as round, elliptical or sometimes appeared polygonal in shape, delta cells are small in size, roughly spherical or polygonal in shape.Immunohistochemical staining of endocrine pancreas revealed glucagon immune reactive cells occupying most of the dark islets, periphery of mixed islets whereas insulin immune reactive cells in the center of beta islets and mixed islets. In conclusion, the endocrine histology and immunohistochemistry technique results of quails are similar to observations in other bird species such as chickens, ducks and geese.
