Patel said the nesting colony was around 60 km away from Flamingo City. “The nesting colony is on the periphery of Kutch Desert Sanctuary. It appears there was a large-scale breeding by greater flamingos in that area. After hatching chicks, generally females fly away while only a few males stay back to lead the flock of chicks,” the RFO added. “We are assuming that some birds of prey might have attacked the flock and the chicks would have got separated from the group during their bid to escape. It is also possible that they could not move as water dried in the area,” the RFO said.
