中文摘要 | 本研究自1996年至1999年在南投縣仁愛鄉瑞岩溪野生動物重要棲息環境內進行小鷦眉的生殖習性觀察。小鷦眉主要在每年的4月中旬至7月下旬進行生殖活動。小鷦眉築巢於陡坡上的苔蘚之中,巢體完全被厚實的苔蘚所覆蓋,僅留開口於側面。巢體呈球形,主要由植物之細根所構成。每窩產蛋 3 枚(n=4),蛋為純白色,無斑點,重 2.05g(n=2),長徑與短徑為 20.0x15.0 mm(n=2)。孵卵期約 16天(n=1),幼鳥由孵化到離巢約需 15 天(n=1)。4 個巢的 12 個蛋中,成功孵化 9 隻雛鳥,孵化成功率為 75.0%,成功離巢有7隻,離巢成功率為 66.7%。小鷦眉的配對方式為一夫一妻制,孵卵、育雛等工作均是共同負擔。育雛期間親鳥餵食幼鳥的食物種類以昆蟲、蜘蛛等無脊椎動物為主。 |
英文摘要 | A field observation was conducted on breeding habit of the pygmy wren babbler pnoepyga pusilla in the Zueyenshi major wildlife habitat in central Taiwan during the period from May 1996 to July 1999. The babbler was a small monogamous bird. Both parents shared the duties on nest building, egg incubating, and nestling feeding and brooding. The breeding season was from late spring to early summer(April to July). The nests were built with small plant roots in mosses on the mountain slope. Each nest was dome shaped, and covered completely by mosses except its lateral entrance. The clutch size was three, each 20.0±1.5 mm in diameter, 2.05g in weight, and white in color. The incubation period was 16 days, and the nestling period was 15 days. Food items of nestlings were small invertebrates, mainly insects and spiders. |
