“…Notwithstanding these views about bird-habitat relationship, studies have shown particular birds to be associated with particular habitats [21,22] and therefore they respond 2 International Journal of Ecology quickly to changing habitats [23][24][25]. Birds have been used as surrogates for assessing the impact of habitat changes [26] and considered as good predictors of habitat quality as they relate to changes that are associated with their habitats [27][28][29].…”

The study assessed factors that influenced bird-habitat preference, diversity, and spatial distribution in Mole National Park. Birds were identified using point count sampling method, while ordination techniques were performed to determine the influence of environmental factors on bird-habitat preference. A total of 4951 individuals belonging to 131 species were identified across the four habitat types in the wet (n = 3033) and dry (n = 1648) seasons. Despite the high abundance and richness of birds in the woodland and shrubland habitats, grassland habitat was the most diverse, due to the high spatial evenness distribution of the birds. Bushfire, patchiness, and animal trampling were the key environmental determinants in bird assemblages and habitat preferences and accounted for 62.02% and 81.82% variations in the two seasons. Rarer birds like White-Backed Vulture (NT) and White-Headed Vulture (CR), Bateleur Eagle (NT), and Woolly-Necked Stork (VU), with high conservation concern, suggest intensification of conservation effort, while the dominance of Sahel Bush-sparrow was probably due to their broad range habitat preferences and ability to adapt to environmental conditions across these habitats. These species could be used as indicators of habitat quality, if future scenarios restrict their movement or distribution in narrow range habitats.

“…Thus, birds are good bioindicators of wetland habitat quality, productivity, and stability. Birds often have correlation with their habitats [15] and have also been used as surrogates for assessing the impact of habitat changes [16,17]. Monitoring the species abundance, habitat preference, and correlationship between species abundance and habitat provides basic information for determining factors causing population fluctuation of bird species [18].…”

Birds are the most conspicuous and significant component of freshwater wetland ecosystem. Presence or absence of birds may indicate the ecological conditions of the wetland area. The objectives of this study were to determine bird species abundance and their relationship with microclimate and habitat variables. Distance sampling point count method was applied for determining species abundance and multiple regressions was used for finding relationship between bird species abundance, microclimate and habitat variables. Bird species were monitored during November, 2007 to January, 2009. A total of 8728 individual birds comprising 89 species and 38 families were detected. Marsh Swamp was swarmed by 84 species (69.8%) followed open water body by 55 species (17.7%) and lotus swamp by 57 species (12.6%). Purple swamphen Porphyrio porphyrio (9.1% of all detections) was the most abundant bird species of marsh swamp, lesser whistling duck-Dendrocygna javanica (2.3%) was dominant species of open water body and pink-necked green pigeon-Treron vernans (1.7%) was most common species of lotus swamp. Results revealed that the habitat characteristics such as vegetation composition (i.e. emergent and submerged vegetations, grasses, shrubs, and trees), vegetation structures (tree diameter and height) and microclimate variables (temperature, relative humidity and light intensity) were the key factors that influenced the distribution, diversity and density of the wetland bird species. This study also revealed that the wetland bird species have adapted a fairly unique set of microhabitat and microclimate conditions.

“…The heterogeneity of vegetation affects productivity (Belisle et al, 2001;Ishikawa et al, 2003;Currie et al, 2004) that potentially offer more niches for avian species through providing a wide range of resources such as food, suitable shelter and nesting sites and also safe roosting sites. Avian richness is associated with the abundance, distribution and diversity of food resources (Marquez et al, 2004;Novotny et al, 2006) and directly associated with vegetation composition and structure (Seymour and Simmons, 2008; AJAS Science Publications Lindenmayer et al, 2010). The difference in vegetation structure and food resources can attract bird species (Campbell et al, 2007;Holmes and Pitt, 2007) that prefers large areas of young sapling, regenerating and early successional vegetation (Costello et al, 2000;DeGraaf and Yamasaki, 2003).…”

Logging activities have encroached into the hill dipterocarp tropical rainforest area since the lowland dipterocarp forests have decreased in size. Hill dipterocarp tropical rainforest is rich in habitat diversity and provide a variety of resources for avian species such as food, habitat and shelter. Therefore it is important to examine the logging effects of hill dipterocarp rainforest on avian species. We compared the avian richness and diversity in different aged post-harvested hill dipterocarp tropical rainforest at the Berkelah Hill Dipterocarp Rainforest Reserve in Maran, Pahang, West Malaysia using mist-netting method. We captured a total of 1908 individuals representing 86 species and 29 families (i.e., 18.55% from two years postharvested forest, 25.10% from ten years post-harvested, 23.90% from twenty years post-harvested and 32.44% from thirty five years post-harvested forests). Forty nine species were caught in two years and ten years, 55 species in twenty years and 59 species in thirty five years' post-harvested forest. Seventeen species were common in all four types of forest. Pycnonotidae, Timaliidae and Nectariniidae were the most dominant families in all types of post-harvested hill dipterocarp tropical rainforest. Diversity analysis indicated that the bird species in twenty years post-harvested hill dipterocarp rainforest was most diverse (i.e., Fisher's Alpha Diversity Index; 16.34) and evenly distributed (i.e., McIntosh Evenness index E; 0.933) as compared to two years, ten years and thirty five years post-harvested forest. However, thirty five years post-harvested forest was richest in avian species (i.e., Margalef's Richness index R 1 ; 9.02) as compared to other post-harvested forest. The findings of this study revealed that logging and recovery process may affects on avian distribution and diversity. However, these effects may vary from species to species.
