摘要2003年1月至2004年5月，我们在印度南部蒂鲁内尔维利的奈纳尔池塘对紫沼泽（Porphyrio porphyrio poliocephalus）的繁殖生物学进行了研究。繁殖活动的高峰出现在1月的第二周至3月的第一周。鸟巢建在靠近池塘岸边的厚厚的漂浮植物上。以凤眼莲、爵床、水浮莲、空心菜和香附子的全株、茎、叶为巢材，用E.最优选粗果。巢的尺寸是可变的。窝卵数从3个到7个不等，平均（± SD）窝卵数为4.5 ± 1.5个，模型窝卵数为4个。所有卵的平均体积为32.3 ± 3.5 cm3。潜伏期估计为19.8 ± 1.2天。巢和蛋孵化成功率估计分别为80.0%和61.1%，而总体雏鸟成功率为42.0%。
Abstract We studied the breeding biology of Purple Swamphens (Porphyrio porphyrio poliocephalus) at Nainar Pond in Tirunelveli, South India from January 2003 to May 2004. Peak breeding activity occurred from the second week of January to the first week of March. Nests were built on thick floating vegetation closest to the bank of the pond. Nesting material consisted of whole plants, stems, and leaves of Eichhornia crassipes, Jussieua repens, Pistia stratiotes, Ipomoea aquatica, and Cyperus rotundus with E. crassipes being most preferred. Nest dimensions were variable. Clutch size varied from three to seven eggs with a mean (± SD) clutch size of 4.5 ± 1.5 and a model clutch size of four eggs. Mean volume of all eggs was 32.3 ± 3.5 cm3. The length of the incubation period was estimated as 19.8 ± 1.2 days. Nest and egg hatching success were estimated as 80.0% and 61.1%, respectively, while overall fledging success was 42.0%.
