The Sunda Pangolin Manis javanica is naturally present in Gaya Island, Sabah, but its population status is largely unknown.  Results from a recent survey using camera traps indicated the presence of a few individuals, who were strictly nocturnal.  There is a strong indication that the population in Gaya Island is in danger of local extinction.  There is also an urgent need to conduct an in-depth study to gather scientific information for further conservation action.

Large areas of tropical forest worldwide have been converted rapidly into forest plantation. Plantation can play an important role in restoring productivity, ecosystem stability, and biological diversity to degraded tropical lands. However, the conversion of forest areas to plantation rapidly resulting birds to lose their natural habitat. Therefore, Acacia mangium plantations have the potential as the refuges for birds. As such, this study was conducted to investigate the bird population in 2-year Acacia mangium plantation, Sabah Forest Industries (SFI), Sabah to determine the bird population density and diversity of 2 year mangium plantation in SFI. There is no published information of the detailed status of bird in SFI yet. Bird survey was done by using point count method. The bird population density was analyzed by using distance 6.2 and bird diversity was calculated by using Shannon-Wiener diversity index. A total of 343 birds belong to 53 species from 21 families were detected. The bird population in 2-year mangium plantation was 17.71 individual per hectare and Shannon-Wiener diversity index for bird diversity was 3.24. This study shows that the bird population density and diversity in SFI were higher as compared to other past studies in Borneo plantation area.

This review addresses the impacts of the noise, the vital role of acoustic communication and the response of the bird in overcoming the increased anthropogenic noise. The rapid development human activities nowadays induce the noise that interrupt the acoustic communication of birds. Disturbance of the signals transmission causes detrimental impact on the birds as they are highly depending on the acoustic communication for their survival, territory defense and reproduction. Continuous exposure of the noise then results in the declination of species richness of which have been stated by several past studies. Although most of the studies stated that the negative impact as a consequences from the anthropogenic noise, however there is positive effect contributed by the noise of which are also recorded in other studies. Moreover, the impacts other variables such as vegetation density that cause major changes to the bird population as compared to noise have also been highlighted in several studies. This indicates that considering several influencing factor is important in measuring impact that leads to the changes that occur within the bird population. Thus, in depth studies on the impacts of anthropogenic noise towards the species of birds by taking into account other contributing variables is important to enable the noise management to be conducted effectively especially in development areas as way in conserving the biodiversity of the bird population.
