合作繁殖鸟类黑脸噪鹛的夏季族群分布格局

黑脸噪鹛(Garrulaxpers picillatus)是我国南方分布较广的一种合作繁殖鸟类。本研究以江西省吉安市及其郊区的黑脸噪鹛为对象,研究了该鸟家族群的夏季分布格局。研究发现,黑脸噪鹛主要分布在市郊疏林灌丛环境,而在城市居民区未见分布。我们同时测量了家族群相互之间的最近距离,其家族群之间的最小距离平均为600m,最小的家族群间距为230m。吉安市城市绿地面积大多小于该鸟的最小活动范围,且缺乏灌丛疏林环境,不宜黑脸噪鹛栖息繁衍。由于具有特殊的生活习性和栖息地环境要求,建议在城市建设规划时,应充分考虑合作繁殖鸟类的保护问题,建设更加和谐的城市生态系统。

THE SUMMER DISTRIBUTION OF FAMILY GROUPS IN COOPERATIVELY BREEDING MASKED LAUGHINGTHRUSH(GARRULAX PERSPICILLATUS)

Masked Laughingthrush(Garrulax perspicillatus) is a cooperatively breeding bird that widely ranged in south China.The summer distribution of family groups of masked Laughingthrush in Ji'an,Jiangxi province was studied.The birds mainly inhabit in suburban area with forestland or scrubs,and far away from urban area with limited green lands.The minimal distance between family groups was also measured.The average minimal distance is 600 m and the least is 230 m.The least distance is larger than those of the par...
