Travelling south on the M5 just past the Clevedon exit, on Friday (2nd March), I noticed in the field off to the left about 25+ swans seemly grazzing in the middle of the field ( not on water). Having not seen this before i am interested to know why or what they were. It seems that it is habit of Bewick swans rather than the more usual Mute swans. Could anyone confirm this please.
