Nagi Dam and Nakti Dam Bird Sanctuary[2] Site description: The Nagi Dam (791 ha) and Nakti Dam (332 ha) are two sanctuaries so close to each other that they can be taken as one bird area. Nagi is 7 km from Jhajha in the Jamui District, and Nakti is a further 4 km from Nagi, occupying similar habitat. These notified sanctuaries are surrounded by rocky hillocks, formed by the damming of streams. Both these waterbodies are quite deep, with a clear water surface. These dams were built to supply water to local farms. There are cultivable lands adjacent to both the waterbodies.
Birds: About 1,600 bar-headed geese (Anser indicus) have been recorded from this site. According to Wetlands International (2002), 1% threshold of this species is 560; accordingly about 3% of the population is found at this IBA site. This site could also attract more than 20,000 birds, if fishing and other disturbances are curtailed during winter when most of the migrants are found in India. Beyond the cultivated areas, these waterbodies are surrounded by barren, rocky terrain. Consequently, dryland birds are also seen, such as the Indian courser Cursorius coromandelicus, chestnut-bellied sandgrouse (Pterocles exustus), yellow-wattled lapwing (Vanellus malabaricus) and Indian robin (Saxicoloides fulicata). The site falls in Biome-12, i.e. Indo-Gangetic plains, but species of Biome-11 are also sighted.
