Population fluctuation, Species variation and habitat utilization pattern of water birds belongs to the family Rallidae, Jacanidae and Charadriidae at selected perennial and non-perennial water bodies of Nalgonda district of Telangana State
Abstract: The present study was aimed to study the population fluctuation species variation and habitat utilization pattern of small and medium sized wetland birds belonging to the families Rallidae, Jacanidae, and Charadriidae at selected water bodies in Nalgonda of Telangana state. The perennial and non-perennial water bodies provide food, shelter, nesting and breeding for many winter and local birds. The population and species richness of these families showed difference in relation to perennial to non-perennial tanks during the study period. A total of 8 species belongs to family Rallidae were recorded at perennial tanks, among which the maximum mean value was recorded for Coots (292.4 ± 119.84) at Dameracharla and the minimum was for Little Crake (3.75 ± 1.91) at Vemulakonda tank. Whereas, in non-perennial tanks the maximum number of coots (86.7l ± 60.67) were recorded at Raigir tank and the minimum number (35.79 ± 14.78)was atBhongir tank. In case of family Charadriidae, a total 9 species were recorded at both perennial and non-perennial tanks. The maximum mean number at perennial tanks was observed for Common Sandpiper at Thummalaguda (208.79 ± 244.04) and minimum for Kentish plover (12.2±6.34) at Vemulakonda, while in non-perennial tanks maximum mean number was observed for little ringed plover (36.29 ± 18.91) and minimum in Green shank (4.75 ± 2.22) at Raigir tank. The percent habitat utilization pattern of different water birds showed similar trend in relation to availability of various habitat types at both the situations.
