昆明动物园野生鸟类多样性调查

Survey on Wild Bird Diversity of Kunming Zoo

在1990—1992年和2006年10月至2008年9月,对昆明圆通山野生鸟类多样性进行样线和定点观测调查,共记录到野生鸟类59种,隶属于7目21科,其中留鸟39种,冬候鸟13种,夏候鸟7种,分别占记录野生鸟类总数的66.1%,22.0%和11.9%。其中,1990—1992年共记录了52种,2006—2008年记录了47种。根据调查结果,分析昆明圆通动物园内野生鸟类种群数量变化情况,探讨变化原因,提出保护建议。

Transect survey and fixed - spot observation were carried out in Kunming Zoo to study the wild bird diversity in two periods of time from 1990 to 1992, and between October 2006 and September 2008. In total, 59species of wild birds were recorded which belonged to 21 families, 7 orders. Among them, 39 species （66.1%） were residents, 13 species （22.0%） were winter migrants, and 7 species （11.9%） were summer migrants, respectively. 52 species were recorded from 1990 to 1992, and 47 species were recorded from 2006 to 2008. Based on the population dynamics of wild bird species surveyed in these two periods of time, the authors explored the contributing causes and proposed some preliminary recommendations on the conservation of the wild bird diversity in the zoo.
