One particular hills inside the Lenggong Valley, is about 50 m above sea
A single hills inside the Lenggong Valley, is about 50 m above sea level and is located around three km north of Lenggong town. The Lenggong Valley is an significant archaeological web page. Proof of Palaeolithic human settlement has been found inside the valley (Majid 994). The vegetation is typically mixed and consists of limestone forest, lowland dipterocarp forest, orchards and secondary forest. Birds have been surveyed in the sites in 3 zones: forest edge, PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/16123306 forest intermediate and forest interior (Fig. ). This survey was carried out on ordinary soils close to the limestone area.Habitat Loss Impact on Malaysian BirdsFigure : Schematic displaying areas of study internet sites in Lenggong limestone region, Perak, Malaysia. Zones are indicated as follows: forest edge, forest intermediate, forest interior. A, B and C refer to the two replicate sets of web sites.Point Counts A pointcount distance sampling strategy was used within the bird surveys. Six transects (two in each forest zone) had been randomly placed in the study sites and surveyed five days monthly. The transects have been approximately 300 m long and spaced 50 m apart, with census stations positioned at 50 m intervals. Bird surveys had been conducted from 0700 to 00 and 600 to 830. The surveys had been only performed in the course of suitable climate (i.e inside the absence of rain or sturdy wind). At every plot, all birds noticed and heard for the duration of a 0 min observation period were recorded. Flushed birds have been recorded at their original position, but flying birds were not recorded due to the fact their original positions were unknown. The bird identification was aided by Robson (2008). Data Evaluation KruskalWallis tests have been performed to evaluate the number of Isoginkgetin species found in the three habitat zones. Separate tests were performed for every single with the 3 bird feeding guilds designated for this study (i.e insectivores, frugivores and other individuals). A twobytwo Gtest of independence was used to recognize the bird feeding guilds that were more likely to be restricted towards the undisturbed area. [Note: species have been counted according to species discovered in forest interior according to their presence or absence in forest edge, and vice versa]. Birds flying silently high in 
the air (e.g swallows, raptors, swifts) were not integrated in any on the analyses.Mohammad Saiful Mansor and Shahrul Anuar Mohd SahRESULTS Bird Species The study recorded a total of 7789 bird detections, that belonged too 00 bird species (Appendix ). Transect walks carried out have been about 260 (05 days six transects 2 occasions every day). A total of 2603 bird detections occurred in the forest edge habitat, 2826 inside the forest intermediate and 2360 in the forest interior. In all, 58 species have been recorded inside the forest edge, 83 species within the forest intermediate and 7 species in the forest interior. A total of species were found only on the forest edge (8.97 ). A total of five species (7.04 ) were identified only inside the forest interior and species was identified only inside the forest intermediate (.20 ).Figure 2: Species accumulation curves of bird species in Lenggong limestone area, Perak.Lonchura striata (283 observations; 0.87 ), Lonchura punctulata (23 observations; eight.eight ) and Amaurornis phoenicurus (88 observations; 7.22 ) have been the three most abundant bird species recorded on the forest edge. Merops leschenaulti (278 observations; 9.84 ) Prinia flaviventris (three observations; four.00 ) and Iole olivacea (02 observations; 3.six ) were the 3 most abundant bird species recorded inside the forest intermediate. Stachyris erythroptera (84 observations;.
