But all of a sudden they have taken a fancy to dead-heading the
primroses. Only the yellow flowers are affected and the poor birds are
no longer "our sparrows" but "YOUR sparrows".

Oh, it's the sparrows then? I wondered who was doing the damage, not
having caught anyone at it! But we now have a handful of sparrows after
some 8 or more years' absence, so I don't mind sacrificing a few
primroses! Wonder why, though - they aren't eaten or removed, just
decapitated.
