摘    要:红耳鹎(Pycnonotus jocosus)为华南区常见鸟类。我们在整理中国鹎科鸟类分布区变化情况时发现,2006年以来红耳鹎的地理分布范围发生较大的变化。本文收集整理了中国1976至2016年期间红耳鹎的分布信息,并利用GIS技术详细地描述分析了该物种的地理分布变化情况。结果显示,红耳鹎jocosus亚种的分布范围呈现一个辐射状的扩散趋势,且向北方地区迁移。除少数扩散属人为因素造成外,基本上都是自然扩散。本研究还初步讨论了生境选择、繁殖习性以及食性等生态特征对红耳鹎扩散的影响,并对该物种地理分布扩散可能造成的影响进行讨论。

关 键 词:红耳鹎  地理分布  扩散  生态习性  Pycnonotus  jocosus  Geographical  distribution  Dispersal  Ecological  habits

Abstract:The Red-whiskered Bulbul (Pycnonotus jocosus) is a common species in southern China. When we reviewed the geographical distributional records of the Bulbuls (Pycnonotidae), we noticed that the geographic area of the Red-whiskered Bulbul has been expanded rapidly in recent years. Based on the publications and field records of Red-whiskered Bulbul from 1976 to 2016, we analyzed the distributed status of the bird using ArcGIS and found the distribution range of P. j. jocosushas been extended to the northern regions in China (Fig. 1), compared to its previously records. Except a few cases of birds released by human, most of expansions were most likely due to natural dispersal. The sub-zoogeographical regions of Red-whiskered Bulbul had increased between 1976 to 2016 (Table 1). We also listed the habitat and abundance of P. j. jocosus in China (Appendix). We suggested habitat selection, breeding and feeding behavior to be important factors for the expansion, and discussed its potential influences.
Keywords:Pycnonotus jocosus  Geographical distribution  Dispersal  Ecological habits
