Must have been at least 40 swans in the fields.
No interactions present.
They will most likely be one of the migrating species feeding up for the flight to there breeding ground. It is getting close to the nesting season for our native swans and they are very territorial.
The strongly curved neck visible on all of the swans, and the relatively long tail visible on many of them, are good indicators that they are Mute Swans - and if you zoom in on the full sized images you can see the orange bills on many of the adults.
I don't see any that look likely to be Whooper Swans (and as they are all similar in size none are Bewick's Swans).
Ilooked carefully at the images and agree with Roy
Certainly not breeding adults. About half of them are in fledgling plumage. Teenage Mute Swans...
I had the advantage of a pair of binoculars as well as my camera and they were all mute swans as far as I could see. There were certainly a lot that weren't adults.
