Avian community structures in two artificial wetland habitats i.e., man-made marsh and lake were investigated to identify the suitability of the habitats for avian species, habitat preference and food resources. Distance sampling point count method detected 35272 bird individuals of 98 species from July to November 2010. Ninty four bird species were recorded from man-made marsh and thirty one species from the lake area. Acridotheres tristis (6.34% of all detections) was the most dominant bird species of man-made marsh and Passer montanus (0.41%) was the most dominant bird species of lake habitat. On the contrarily, Microhierax fringillarius and Turdoides earlei (each 0.01%) were the rarest species of man-made marsh and Dinopium javanense (0.02%) was the rarest species of the lake habitat. The bird relative abundance of man-made marsh and lake habitats was significantly different (F 1,194 = 50.3, p<0.05). Community analysis indicated that bird species of man-made marsh were more diverse i.e., Shannon’s index (N 1 = 3.92) and rich i.e., Margalef’s index (R 1 = 8.93) than the lake habitat. Insectivore (marsh; 21.13% and lake area; 1.21%) was the most dominant guild in man- made marsh and lake area. In contrast, Piscivore (0.14%) was the rarest guild comprised of only one species in marsh habitat. The results of this study revealed that the man-made marsh was more capable to attract a higher number of bird species and diversity than the lake habitat.

INTRODUCTION vegetation to trap the sediements from surrounded catchement areas and also to retain water for drinking or Worldwide, more than 50% of natural wetland areas irrigation purpose (Vymazal, 2010). As the wastewater have been lost due to human activities which had flows from catchment area through the length of the adversely affected hydro system, plant growth and avian aquatic habitat, suspended solids and matter settle out and communities that depend on wetland habitats directly bottom sediments trapped toxic contaminants and and indirectly for various activities (Fraser and Keddy, pollutants through microbial interaction (Kirby, 2002). 2005; Coleman et al ., 2008; Mitsch, 2010). Due to loss Vegetation plays a vital role in hydrological processes, and degradation of natural wetlands, man-made marshes reducing soil erosion, filter and trap sedimentation from and lake areas had become ecological important habitats catchment inflows, reduced turbidity that had for many avian species (White, 2003; Yaukey, 2011; contributed to high water quality and aquatic life Zakaria and Rajpar, 2013).

Bird Surveys can mitigate the adverse effects of wetland loss and degradation (Connor and Gabor, 2006; Sim et al ., 2008; Bird were surveyed employing the distance sampling Ma et al ., 2010; Rajpar and Zakaria, 2013). point count technique to determine the aian community Birds are the bioindicators of aquatic habitats such as structures i.e., relative abundance, diversity, feeding man-made marshes and lake areas. Their occurrence or guilds and habitat preference from July to November, absence of bird species may indicate the habitat 2010. A total of 89 point count stations (i.e., 45 point characteristics and productivity of the particular habitat count stations in man-made marsh and 43 point count (Noble et al ., 2008; Larsen et al ., 2010; Rajpar and stations in the lake habitat) were established at 300 m Zakaria, 2011a; BLI, 2013). Investigating avian intervals along the wetland edges. This distance was community structures (i.e., abundance, diversity, feeding selected to obtain more reliable data and avoid the guilds and habitat preference) is a crucial tool to determine detection of the same bird individual at more than one the habitat suitability and to detect the changes within station. The birds were surveyed in each month for eight particular habitat during specific period (DeSante et al., days and each point count station was surveyed for 10 2005). Information related to avian community structures min by walk along trails set along the dikes.

The distances from bird individual to observer suitability of artificial wetland habitats i.e., man-made was recorded using visual estimation for each bird marsh and lake area to understand the importance of each individual within the range of 100 m. The surveys were habitat as alternative habitat to natural one for future conducted by a single observer between 0730 and 1100 conservation and management planning. h. This period of time is an appropriate, as most birds are active early in the morning. The survey methodology 2.
