British race 'graellsii'
No interactions present.
Looks like a male with its summer coat.
Interesting to note that it does not have the bright yellow legs that are normally characteristic of this species. Presumably a 3rd year bird that has only just lost its last brownish flight feathers. I agree with gb5636 that this is probably a male, as the head and bill are so bulky.
There were two birds present and both had butterscotch-coloured legs. The MacMillan Guide to Bird Identification states that the legs are bright yellow in summer and creamy-yellow in winter.
The grey streaking starting to appear on the head and neck suggests that this bird is almost into winter-plumage.
