| Summary: | 碩士 === 國立屏東科技大學 === 野生動物保育研究所 === 100 === In this study, I used stable hydrogen isotope (δDf) to survey migratory restlessness (Zugunruhe) of black-faced buntings (Emveriza spidocephala) and explore their migration pattern. Total of 33 black-faced buntings were bought or captured in this research, the breeding sites of black-faced buntings obtained by examining stable hydrogen isotope (δDf) of their feathers. This research was executed from February to December, 2011. Results revealed that the distance from breeding sites was related to migratory restlessness and the date of migratory restlessness started, but not related to the date of migratory restlessness finished. I speculated that, the distance from breeding sites farther, the migratory restlessness would achieve migration started earlier. Conversely, if the distance from breeding sites nearer, the migratory restlessness lower and migration started later. There is no relation between the date of migratory restlessness of black-faced buntings and the distance from breeding sites, I presumed that birds would rest and supply power at stopover site when they are migrating, this probably effect the date of migratory restlessness finished. This research also found out the migratory restlessness of black-faced buntings was related to their weights, I assumed the foraging strategy of black-faced buntings is supplying energy and migrating in the meantime. Time of the highest migratory restlessness of black-faced buntings was 22:00 to 00:00, it might be the migration peak of black-faced buntings. In the monthly variation of migratory restlessness of black-faced bunting in all year, there is no apparent stop from February to November, only the variation of gradually increase or decrease, I concluded that besides the endogenous control, migratory restlessness of birds was also effected by temperature, physiological condition and other factors.
