Looking at the photos of the first bird again, I agree that there is a white collar ring around it's neck. But at first glance, the bill looks too big for a Kentish. I thought about the bird's angle to the camera which could distort the neck patterns, but I looked through a lot of images and no Greater Sand Plover have a white collar ring going this far back.
So yes, I will say you are right on this one, this is a Kentish Plover!! Sorry for the incorrect identification.
