The rooks are watching the plough turning the earth and gathering on the power lines waiting for the inevitable worm feast.
Their behaviour is strange to watch, they fly down and grab a snack and then rush back to the temporary roost; the look-out spots us approaching with the two terriers and the restless, skittish clamour are airborne again. Obviously rooks don't get indigestion by eating on the run!
Why don't they just stick to working the furrows with the seagulls and enjoy an uninterrupted feed? Maybe it's a sixth sense of some kind but if it is a sixth sense the seagulls have not been blessed with it.
Maybe they aren't rooks at all but crows but then that would disprove my farming uncle's definition that three crows means they are rooks and one rook means it's a crow. Now stay with us at this point, because if they're a flock of rooks it's a 'clamour' and if it's a flock of crows it's a 'murder' but is a murder one or two?
We're now definitely 'confused' of West Norfolk!
