中文摘要 | [摘要] 本研究以地面觀測方式,調查2010年春、秋二季恆春半島過境日行性猛禽的數量和種類,並採用當地的逐時氣象資料,分析秋季氣象因子對數量最多的赤腹鷹(Accipiter soloensis)與灰面鵟鷹(Butastur indicus)等二種過境猛禽過境行為的影響。春季調查共記錄2科12種、41,400隻次遷移性猛禽,秋季的調查則共記錄2科12種、179,865隻次遷移性猛禽,春秋二季皆以赤腹鷹和灰面鵟鷹的數量最多。春季灰面鵟鷹的過境高峰在3月中旬,赤腹鷹的過境高峰在於4月下旬;秋季赤腹鷹的過境高峰則在於9月下旬,灰面鵟鷹的過境高峰則在10月中旬。9月赤腹鷹偏好在溫度和氣壓較高、風速較低的好天氣出海南遷,10月因東北季風開始盛行,灰面鵟鷹偏好在降雨較少且風速較低的清晨出海。 |
英文摘要 | ABSTRACT A ground survey was conducted on the migratory raptors on Hengchun Peninsula, Taiwan in the spring and autumn of 2010. Also analyzed was the effect of autumn weather conditions on the migration of the gray-faced buzzard (Butastur indicus) and Chinese goshawk (Accipiter soloensis), the two most abundant migratory raptors Twelve species, or two families, of raptors were recorded in each seasons. There were 41,400 individuals in spring and 179,865 individuals in autumn. The gray-faced buzzard and Chinese goshawk were the two most abundant species in both seasons. The migration of the grey-faced buzzard peaked in mid-March in spring and in mid-October in autumn, while that of the Chinese goshawk peaked in late April in spring and late September in autumn. During autumn migration, the Chinese goshawk bounded southward in weather conditions of tail wind, higher air temperature and pressure, and lower wind speed; while the grey-faced buzzard migrated south under less rain, lower wind speed and lower air temperature, conditions typically found in early morning, when the north-eastern seasonal wind began to prevail. |
