Despite being the most numerous species of Flamingo, Lesser Flamingo is classified as near threatened due to this declining population and the low number of breeding sites, some of which are threatened by human activities.(Mehra, 2011). Previous sighting of flamingos around Ajmer was reported by Choudhary, (2007). Another study on avifaunal diversity was also carried out in Ajmer district by Sharma et.al.(2013) ; Dutt and Prakash (2018) where the species was only sighted once throughout the year.

After seriously rescanning the lake one more Flamingo was spotted to be standing at one side of water . Out of these four individuals, the two foraging flamingos were adult while the lone one was an immature.
The identification of bird was confirmed by using field guide Grimmett, et al. (1999); Hasan (2001) and Kumar, et al.(2005) .
