Abstract

Four species of vultures were surveyed using road transects in two parts of the Moyar Valley, three of these are Critically Endangered by IUCN criteria and one is Endangered.  The vulture study was done for the first time in Nilgiri North Forest Division and Sathyamangalam Tiger Reserve of Moyar Valley to determine the flock size in the three species of vultures and also to get a rough estimation of vultures. The results show higher flock size and higher densities in Nilgiri North Forest Division than in Sathyamangalam Tiger Reserve and the most numerous of these was the White-rumped Vulture.  There is also evidence of seasonal movements in Nilgiri North Forest Division.  These data represent the first systematic survey results from the area and demonstrate the significance of the Moyar Valley for all four Endangered vulture species, probably the main stronghold remaining in southern India.  They are White-rumped Vulture Gyps bengalensis, Indian Vulture Gyps indicus, Red-headed Vulture Sarcogyps calvus and Egyptian Vulture Neophron percnopterus.  The study recommends that immediate long-term conservation efforts should be taken to save the Critically Endangered vultures in the Moyar Valley.
