Abstract

Morphological features of the taste buds and the distribution of the taste pores of the Large-billed Crow Corvus macrorhynchos were investigated by scanning electron microscopy (SEM) and light microscopy (LM). SEM revealed two types of openings on the oral epithelium of the Large-billed Crow. The larger type (more than 50 μm in diameter) was spiral or spindle shaped, while the smaller type (less than 10 μm in diameter) was circular in shape. The former corresponded to the opening of the salivary glands, and the latter to the taste pores, as revealed by conventional LM. An average of 537 (SE = 38.4; N = 4) taste pores were observed, of which 82% were located in the lower mandible and 18% in the upper mandible. The anterior part of the tongue was found to be devoid of taste buds and pores. In addition, taste buds were found to be composed of three cell types: light, dark, and sustentacular.
