A flock of these in my field this afternoon.

About the size of a partridge, foraging alongside Redwings, which are much smaller.  There are distinctive yellow spots on its back, long thin beak and white chest.

A Plover of some kind?

Thanks Steve, that's the conclusion I came to after thumbing through a few more books.
