 note = {Marine mammals and marine birds perform diving to forage underwater. Recent technological advances have led to rapid progress in our understanding of diving behavior, but additional research is required into feeding behavior to determine the timing of prey ingestion, prey mass, and prey type. To achieve a comprehensive understanding of the foraging and diving behavior of these endotherms, it is essential to integrate information on feeding behavior with other data. The challenges involved in developing an appropriate research method have been addressed, and several methods have been tested and used in the field, including the stomach temperature method, the esophagus method for marine birds, the stomach temperature telemeter method for seals, and the beak magnet sensor method. In the present study, I review these methods, suggest the necessity of their further development in field studies, and propose a new practical method that involves the measurement of jaw movements underwater as an indicator of the feeding behavior of seals., 海生哺乳類と海鳥の採餌潜水行動は、近年のバイオロギングの技術の進歩によってよく理解されるようになっています。しかし捕食した獲物の大きさ、種類、その消化過程をより詳しく調べるために、さらなる手法が必要です。本論文では今までの手法を概観し、また胃温度センサーや嘴マグネットセンサーなどの新手法の必要性を述べ、野外で計測するための実用的な方法を提案します。},
