Bird surveys were conducted in the Bukit Kepala Gajah limestone area in Lenggong, Perak from July 2010 to January 2011. The study area was divided into three zones: forest edge, forest intermediate and forest interior. A point-count distance sampling method was used in the bird surveys. The study recorded 7789 detections, representing 100 bird species belonging to 28 families. Pycnonotidae, Timaliidae and Nectariniidae were the dominant families overall and showed the highest number of observations recorded in the study area whereas Motacillidae showed the fewest observations. The bird species were grouped into three feeding guilds: insectivores, frugivores and others (omnivores, carnivores, nectarivores and granivores). The species richness of insectivorous birds differed significantly among the forest zones sampled (Kruskal-Wallis: α=0.05, H=10.979, d.f.=2, p=0.004), with more insectivorous birds occurring in the forest interior. No significant differences were found among the zones in the species richness of either the frugivore guild or the composite others guild.
2010年7月至2011年1月，在霹雳州冷岳的武吉吉打石灰岩地区进行了鸟类调查。研究区域分为三个区域：森林边缘、森林中间地带和森林内部。鸟类调查采用了点计数距离抽样方法。该研究记录了7789次观测，代表了属于28个科的100种鸟类。总体而言，鹎科、画眉科和太阳鸟科是优势科，在研究区域记录的观测次数最多，而鹡鸰科的观测次数最少。鸟类被分为三个取食类群：食虫鸟类、食果鸟类和其他类群（杂食性、肉食性、食蜜性和食谷性）。在所采样的森林区域中，食虫鸟类的物种丰富度存在显著差异（Kruskal-Wallis检验：α=0.05，H=10.979，自由度=2，p=0.004），森林内部的食虫鸟类更多。在食果鸟类类群或其他类群的物种丰富度方面，各区域之间未发现显著差异。
