The results recommend that insectivorous birds would be the feeding guild that is certainly most influenced by habitat disturbance. Other research have also shown that insectivorous birds are far more sensitive to habitat disturbance than other feeding guilds (Table ). KruskalWallis tests indicated that only the insectivorous birds showed a substantial difference in species richness among the zones. Extra insectivorous birds had been observed in the forest interior. Insectivores are very sensitive to habitat modification (Laurence et al. 2004) and they seem to become confined to locations with significantly less disturbance (Tvardikova 200). Normally, insectivores have high habitat specificity. They may be additional strongly restricted towards the forest interior than other avian feeding guilds, in particular inside the tropical forest exactly where habitat loss and its consequences are largely impacted (Sekercioglu 2002). Insectivorous birds 
show a sturdy tendency to turn into far more specialised and sensitive to prey abundance and behaviour since, unlike fruits, flowers and seeds, invertebrates actively prevent insectivores (Snow 976). The negative correlation in between the species richness of insectivorous birds along with the degree of impact from habitat loss may possibly be because of the high degree of ecological specialisation amongst insectivores, meals scarcity within the disturbed habitat, adjustments in microclimate and in predation prices, and interspecific competitors.Figure 3: Numbers of insectivorous, frugivores and other individuals bird species in three zones; forest edge, forest intermediate and forest interior.Habitat Loss Impact on Malaysian BirdsTable : Numbers of bird species found in PP58 chemical information lowland tropical forest habitats.

Because of this, they are far more sensitive to subtle modifications (Canaday 997). As a result, insectivorous birds have created a lot of specialised niches and forage in certain narrowly defined microhabitats (Sekercioglu 2002). The higher abundance of insects in Sarawak’s forest causes insectivorous birds to hunt within a wide range of microhabitats but in specific niches (Fogden 972). Inside the subtropical forest in Hong Kong, microhabitat utilisation differs involving Parus big and Sitta frontalis.
