Dear Bill, Dr. Yogesh, Savithri ma'am
These birds were also seen in Basai, on 7 February if I remember correctly. We (Savithri and I) felt the first one was dunlin. Length of the bill here is about the length of the head.
In the second photo I'm really not sure of which is Dunlin or if any is at all. The bird at the bottom shows a indistinct supercilium and an unevenly decurved bill though.These birds were also seen in Basai, on 7 February if I remember correctly.

regards BillAs I told you I first noted that Some Curlew Sandpipers have dark markings on their rumps when I hjandled birds for ringing at Basai and also at Point Calimere. In the BTO Guide 17 "Guide to identification and Aging of Holarctic Waders"(a British ringers' manual) it states "Also has a white rump although this may be partly obscured". Dark markings on the white rumps of adults are also mentioned in the seminal Handbook to the Birds of the Western Palaearctic (Vol111).This is something of a red herring but I just wanted you to be aware that the seemingly absolute certainties in many field guides often omit exceptions. Obviously the white rump on Curlew Sands is the norm. My concern is that recently there has been a tendency to claim Dunlins when most photographs I have seen show Curlew Sands (which are much the commoner in the Delhi area). However Dunlin do occur occasionally and usually as individuals in parties of the much commoner species. Just today two pics,one definite and one probable were posted for instance.--On Wed, Feb 18, 2015 at 7:38 AM, Yogesh Parashar <parasharyogesh@gmail.com> wrote:Dear Bill,I have re-looked at Grimmett, Krys, and the BNHS guide.All texts clearly say Dunlins have 'dark centre to rump' and Curlew Sandpipers have 'broad white rump band' or 'pure white rump'. This is listed as a distinguishing feature.Could you please share the references which say anything to the contrary.Regards,Yogesh Parashar.--
