Heads of ten healthy adult ostrich obtained from slaughter house were the constituted materials of the study. The Harderian gland (HG) was dissected out, and all of the gross morphometrical parameters including length, width and thickness as well as weight of left and right glands were recorded. Tissue sections were stained, using haematoxylin and eosin, Masson trichrome, periodic acid- Schiff and Alcian blue (pH 2.5) techniques. In ostrich, HG was an orbital organ located ventromedially around the posterior part of the eyeball. It was an oval flatted shape, light pink colour with irregular outline and was pointed in the dorsal end. Its mean length was 35.30  2.84 mm and 35.55  3.58 mm in left and right sides, respectively, and mean width 15.30  1.20 mm and 15.65  1.18 mm in left and right sides, respectively. There was no significant difference between length, thickness, weight and width of left and right glands. Histological results showed that the glandular epithelium was multilobular and compound tubuloalveolar. The gland was surrounded by a connective tissue capsule, and the epithelium was lined by simple columnar epithelial cells of varying height. The secretion of HG was mucous and the secretion type was apocrine. Mucosubstance analysis revealed that secretory units contained acidic and neutral glycoproteins. The granules within the epithelial cells lining the intralobular and inter-lobular excretory ducts of the gland were positive for periodic acid-Schiff and Alcian blue (pH 2.5).
