This study documents the common among all the species of famingos. Food and populaton structure and conservaton threats afectng the populaton and habitat of the famingos at Najafgarh Jheel Bird Sanctuary and suitable habitat are key factors afectng its distributon Basai wetland in Haryana, India. The study areas were surveyed (Ali 1987; Jenkin 1957). The Greater Flamingos primarily monthly between May 2019 to February 2020 at regular intervals. A Nikon 8 X 40 feld binoculars and a Nikon SX60 camera were used feed on phytoplankton, zooplankton, crustaceans, to observe focks of P. roseus. A total of 65 focks of famingo were molluscs, sedge seeds and the remains of higher plants observed, and 6,768 individuals were counted using point counts (Ali 1987; Tere 2005).

Najafgarh Jheel Bird Sanctuary holds a major proporton of their populaton comprising about 91.78 % and Basai wetland depth, and infuence of predator are some important holds about 8.21 % of their populaton, while 52.46 % of the total factors that infuence the populaton and distributon of populaton were classifed as adults, and 47.53 % were juveniles (sub- waterbirds (Arengo & Baldassarre 1995; Baldassarre & adults).

As untreated Populaton abundance and conservaton threats for sewage fows into it, the Jheel is one of the most Greater famingos were carried out in Gurugram District contaminated, though stll an important habitat for of Haryana. The current study recommends conservaton many species of birds and plants. measures to mitgate threats to famingos and other species of waterbirds in these IBA sites. Methods The selected sites were surveyed on a monthly Study area basis, from May 2019 to February 2020. The data were Basai wetland collected from sunrise to sunset. A combinaton of feld Basai wetland (28.468N, 76.981E; 216–219 m) is observatons, and tme series imagery were used to named afer the village Basai, in Gurugram District in identfy changes in the open water area. Observatons Haryana, India. The wetland close to Basai-Dhankot were carried out by using a Nikon 8 X 40 feld binoculars railway staton and 8 km from the Sultanpur Natonal and a Nikon SX60 camera. Birds were counted monthly Park. It is a perennial shallow water wetland with an area using the point count method (Sutherland 2006; Bibby of 250 acres and is an IBA that has global conservaton et al. 2000) and locatons of each sightng of focks signifcance as it supports populatons of several were recorded by means of a hand-held GPS device. endangered, vulnerable, and threatened bird species To construct a distributon map of the study area the (Islam & Rahmani 2004). geographic informaton system (GIS) sofware (Arc- GIS 10.5) was used. Various threats were determined Najafgarh Jheel Bird Sanctuary through direct observatons. A total of 17 people were Najafgarh Jheel Bird Sanctuary (28.498N, 76.946E), interviewed throughout the study period. To reach study located on the Delhi-Haryana border, and estmated sites at various locatons, diferent modes of transport around 7 km long, is the part of Sahibi River. The were used. Adults and immature (sub-adults) birds were Najafgarh Jheel Bird Sanctuary extends to two villages, identfed based on their plumage (Allen 1956; Johnson Kherki-Majra and Dhankot with an area of 298 acres, in & Cezilly 2007).

Najafgarh Jheel Bird Sanctuary holds a major proporton of their populaton comprising 91.78 % and Basai wetland holds 8.21% of their populaton (Table 1). Among 6,768 individuals of Greater Flamingos 52.46 % were classifed as adults and 47.53 % were juveniles (sub-adults), while chicks were not observed. Figure 2. Populaton age structure
