摘要/Abstract

摘要： 巢捕食是导致鸟类繁殖失败的主要原因之一。2012年5—7月，在贵州宽阔水自然保护区，采用红外自动摄像机对鸟类地面巢的捕食者进行了调查。在15个自然巢中监测到7个捕食事件，包括黄鼬(Mustela sibirica) 2个(28.6%)，红嘴蓝鹊(Urocissa erythrorhyncha)、喜鹊(Pica pica)、果子狸(Paguma larvata)、白腹巨鼠(Rattus edwardsi)和王锦蛇(Rattus edwardsi)各1个(占14.3%)。在22个人工巢中共记录到17个捕食事件，其中果子狸11个（64.7%），白腹巨鼠5个（29.4%），红嘴蓝鹊1个（5.9%）。兽类捕食者占83.3%，是鸟类地面巢的主要捕食者。各种捕食者捕食的时间不同，兽类捕食者主要出现在黄昏到凌晨之间，而鸟类和蛇类捕食者主要出现在白天。

Abstract: Nest predation is the primary cause of nest failure and leads to low or zero breeding success for most birds. From May to July, 2012, infrared cameras were used to identify predators of ground nests of birds in Kuankuoshui Nature Reserve, Guizhou, southwestern China. A total of 7 predation events were recorded for 15 natural ground nests, including 2 (28.6%) by Siberian Weasel (Mustela sibirica), 1 (14.3%) by Red-billed Blue Magpie (Urocissa erythrorhyncha), Magpie (Pica pica), Civet Cat (Paguma larvata), Edward’s Rat (Rattus edwardsi) and King Rat Snake (Elaphe carinata), respectively. Totally, 17 predation events were recorded for 22 artificial ground nests, including 11 (64.7%) predated by Civet Cat, 5 (29.4%) by Edward’s Rat and 1 (5.9%) by Red-billed Blue Magpie. Mammals were responsible for 83.3% of total predation events, and thought to be the main predators of ground nests of birds. Time of predation varied with different types of predators, i.e. mammal predation occurred mainly at night, while both predation events by birds and snakes were exclusively diurnal.
