| Outline of Final Research Achievements |
In six species of penguins, the structure of feathers was examined by gross-anatomy and microstructural observation using SEM. In the digits of Owls, moreover, the dynamics was analyzed using CT scanner. In the examination of penguin feathers, contour, down, semiplumes and filoplume feathers were identified, and there are no apteria in all penguins. The contour feathers were recognized in the trunk and flipper. The down feathers appeared on the head, trunk and brachial parts of flippers, and the filoplumes was noticed in head and trunk. In the flippers, contour feathers with the flat rachis were densely distributed and indicated the scale-like arrangement. In the Owl digit analysis, the digits showed anisodactylous. However, the forth digit directed the palm side into the medial direction. Therefore, when the tarsal join was flexed, the forth digit was moved into the medial direction.
