Abstract
Present study was conducted in and around Nainital Lake to understand the status of raptors in forest habitats.Observational investigations carried out using avian study field binocular and DSLR camera and line transect method was adopted for bird counting. Fourteen species of raptors belonging to family Accipitridae and Strigidae were recorded during study period i.e.February 2017- March 2018. Steppe Eagle and Black-eared Kite have highest population and most dominant species in the study site,  whereas Brown Fish Owl, Oriental scops Owl, Tawny Owl were rarely observed. Field study was conducted in three different seasons i.e. winter, summer and rainy. Maximum number of individuals were recorded during winter (94) followed by summer (77) and rainy (50) season respectively. Data was analyzed by Shannon-wiener diversity Indies, species diversity (H=1.718), species richness (SR=2.408) andevenness (E=0.3983). Species diversity was more (1.794) in winter followed by summer (1.758) and rainy (1.406) season. In terms of distribution status of raptors 79% were resident, 14% winter visitor, 7% summer visitors. According to IUCN red list (2018) one species was Endangered (E), one species Near Threatened (NT) and twelve species were Least Concern (LC).
