More of a wader ID quiz?

I grabbed these shots at Merkinch Local Nature Reserve just outside Inverness last week. I knew there was something different over on the left end, I now know what but, there seem to be a couple of other odds and ends mixed in. Could anyone have a look through and let me know what they see please?

For example, there's a duck just right of centre and far right, what looks like a smaller wader? Thinking
