having little experience with lesser and greater crested terns, i still think you are right with Thalasseus bengalensis. mantle looks pale, bill orange-yellow and not so deep based. also size relative to the gull-billed tern looks to be in line with lesser-crested. greater crested are really huge in my memory.
 
Ditto to Lesser Crested; as well as the above notes, am I right that winter plumage Greater would also have rather less black on its nape?
 
Yes lesser crested. Just thought I'd note difference between preview on phone (where bill appears pale yellow=greater crested) and what I actually saw when I opened the image (orange=lesser)
