We too got a couple of these Ruffs in Jamnagar last December, and I understood from the chain of comments then from experts, that those were male Ruffs moulting.

Rajneesh there were thousands of Ruffs there but these 2 were different. As far as I understand Environmental Factors uni- formally stimulates Internal Factors ( Endocrine System+ Hypothalamus) I am of the opinion for Leucism and variation in the plumage coloration and that too like these 2 specimens which is not uniform in deposition of melanin and carotinoids itself is self explanatory of leucism with my little knowledge of genetics .I have been observing these birds from 2010 Feb -March till today Feb 2014 on every migration for this particular reason.

This seems to be another example for Ruffs discussed in separate threads earlier. These seem to be birds in molt or just a cause of varied plumage and not leucism
