Since Slyvester went, the rest of the geese have been behaving quite differently. They have been wandering more over their whole area (the Gathering and Collecting paddocks) and have been far 'chattier' too. Slyvester's brother (as yet un-named) seems to have stepped up to the mark and taken over as leader and as whole they do now seem, once again, to be a more cohestive group.
It's kind of sad. It reminds us of when Stlvester was well: leading his flock with real charcter and confidence. Through his brother, his 2 sons and Guivevere though, his memory and his line will live on.
