 note = {P(論文), As a part of the ecological studies on Adelie penguin, the banding was performed by the present author. 55 adult penguins were marked at the Ongulkalven rookery between 17 and 20 January 1972. The observation of the homing behavior of the marked birds has been continued till the present by the personnel of the Japanese Antarctic Research Expedition. The results obtained till 1977 austral summer are described in the present paper. The individual number of the marked birds which returned to the rookery decreased at a constant rate of about 38% annually and diminished to four birds in the summer of 1977. The age of the four birds was over 7 years old. The nest sites of 29 individuals out of 55 marked birds were identified in 1972. Out of the 29 birds 17 returned to the original nests in the 1972-73 breeding season. The affinity of Adelie penguin to the area around the original nest site is firm. However, the returned birds do not always strictly prefer the original nests. The removal between the rookeries adjacent to each other was observed. But the number of marked birds found in the neighboring rookeries was three out of 55 between 1972 and 1977.},
