What type of bird is this?

I was on a walk and I saw a bird, I was wondering if anyone could identify it for me please? :) It was quite a plump bird, short. It's feathers were a mixture of overlapping creams, blacks, browns and reddy-browns. The head was white with a black strip and a red ring around the eye. The beak was quite short and the tail feathers were fairly long and skimmed the floor. I think I saw two as one time I noticed it had thorn like spikes on the back of its legs, and then it didn't. I saw it by Gower. We were on the common in a field of spiky dark green bushes.It was on a mountain/hill next to the sea. I do not think it was a Partridge, Pheasant, Quail or Grouse, although it did bear some similarities. Thanks for any help nd sorry I could not be more detailed.
