Sharma 2 1 Puspaswini, 1830-Mahatab Road, Old Town, Bhubaneswar, Odisha 751002, India 2 Natonal Chambal Sanctuary, Morena, Madhya Pradesh 476001, India 1 [email protected] (corresponding author), 2 [email protected] Abstract: River Chambal, in northwestern India, is a tributary of the Gangetc River system. It fows through the states of Rajasthan, Madhya Pradesh (MP) and Utar Pradesh (UP), and the Natonal Chambal Gharial Sanctuary (NCGS) encompasses a 572km stretch of the river from Keshoraipatan in Rajasthan to Pachhnada in UP. The sanctuary includes about 15km of river Yamuna afer confuence with Chambal. During annual monitoring of Gharial in Chambal the Indian Skimmer, Rhynchops albicollis numbers were also counted in 12 study zones for 17 observaton years spread between 1984–85 and 2015–16. The number of skimmers was below 355 for 15 of the 17 observaton years. Skimmer counts were higher in 1995 at 555 individuals. The count for diferent study zones is not uniform, but with reference to Rajghat at the crossing of Natonal Highway number-3, the count upstream is lower than downstream with an excepton in the year 2011. The river downstream appears to be a beter skimmer habitat with beter availability of fsh, and long stretches of fowing water along low-lying sandy banks. The study calls for contnued, coordinated and strengthened atenton to NCGS for added conservaton of locally migratng birds. The research and management connect in NCGS is a model where long term ecological monitoring has been possible because of simple and implementable protocols that were used unchanged over such a long period by a set of identfed feld personnel.

Populaton studies and radio tracking of Gharial Gavialis gangetcus were started in the winter of 1983– Natonal Chambal Gharial Sanctuary 84 in Natonal Chambal Gharial Sanctuary (NCGS) (Singh There are two sanctuaries on Chambal for the 1985; Habib et al. 2010). This study gave emergence conservaton of Gharial Gavialis gangetcus. The to ancillary feld observatons and conservaton Jawahar Sagar Sanctuary in Rajasthan was gazeted recommendaton for various other indicator species in October 1975, followed by the Natonal Chambal (Singh 1999). One of the highlights from 1983–1985 Gharial Sanctuary by the states of UP, Rajasthan and MP is the richness of wetland birds in Chambal (Sharma & in three separate notfcatons between January 1979 Singh 1986). Long-term monitoring untl recent tmes and September 1983. NCGS starts from Keshoraipatan, has ofered the scope to beter understand the scenario about 18km afer Kota Barrage, and extends up to related to the birds of Chambal. The present study on Pachhnada (Fig. 1). The length of the sanctuary is 572km the Indian Skimmer Rhynchops albicollis is one such that includes about 15km of Yamuna afer confuence long duraton study. It gives an account of the trend of with Chambal. The width of the sanctuary extends out number of skimmers observed in NCGS based on the of the riverbank, to cover adjacent important areas in data collected during Gharial surveys conducted untl UP, but is limited to 1km on either banks in Rajasthan 2015–16. and MP. In 1983, the Government of India established a River Chambal feld camp of the erstwhile Central Crocodile Breeding River Chambal in northwestern India originates and Management Training Insttute of Hyderabad at from the Singar Chori peak of Vindhya Range near Deori Campus in Morena District of MP.
