The dorsal lingual surfaces of rainbow lorikeet (Trichoglossus haematodus) were examined by scanning electron microscopy. Macroscopically, the tongue of the rainbow lorikeet has a finger-like shape. Three parts are distinguished in the dorsal surface of the tongue: the apex, body, and root of the tongue. The apex of the tongue has numerous processes inclined toward medial side from lateral side. These processes are rod-like structure and smooth surfaces. Many grooves are observed in both lateral sides of the lingual body. A large opening of the lingual gland exists in central part of the lingual root and some large openings of the lingual glands exist in both lateral sides of the lingual root.
