摘要
白喉噪鹛Pterorhinus albogularis是一种典型的森林鸟类,其基础生态学资料十分匮乏。2022—2023年繁殖季(4—9月),在云南乌蒙山国家级自然保护区小岩方片区内,对白喉噪鹛的繁殖生态进行了初步研究。共记录了20群89只次白喉噪鹛,区域种群密度为(28.3±12.2)只/km2。发现的4个白喉噪鹛巢均在筇竹Qiongzhuea tumidinoda上。巢呈杯状,隐蔽度高。4个巢的窝卵数均为3枚,卵呈暗蓝色。白喉噪鹛具有合作繁殖行为。该鸟类偏好在高大乔木数量多、盖度高和植被总盖度大的栖息地活动。Logistic回归分析表明:乔木因子和植被总盖度是影响白喉噪鹛活动区选择的关键生态因子。本研究结果丰富了白喉噪鹛的生态生物学资料。
White-throated laughingthrush(Pterorhinus albogularis)is a typical forest bird.Currently,there is limited ecological information available on the species.In order to deepen the understanding of this bird,a preliminary study on the breeding ecology of P.albogularis was conducted within the Xiaoyanfang area of Wumengshan National Nature Reserve(Yunnan Province)during the breeding seasons(from April to September)in 2022 and 2023.A total of 89 individuals in 20 flocks were observed,with a local population density of about 28.3 ind./km2±12.2 ind./km2.Four nests were found on Qiongzhuea tumidinoda.The nests are cup-shaped and well-concealed,with a clutch size of 3 eggs.The egg color is cyaneous.P.albogularis was found to exhibit cooperative breeding behavior,and prefers to move around in the habitats with abundant tall and large trees,high tree cover,and high total vegetation cover.Logistic regression analysis indicated that tree factors and total vegetation cover might be the key ecological factors influencing the home-range selection of this species.This study enriches the ecological and biological information of P.albogularis.
