Picture from the BBC Radio 4 website for a series called "World on the Move".
I lost my patience with animal programmes decades ago.
I just don't care where these, for instance, Wildebeeste came from, or where they are going to, or why.
I haven't for decades.
Probably Radio 4 will boast some sound footage of Wildebeeste clomping around. And a commentator saying, in hushed tones, "these Wildebeeste are moving from somewhere to somewhere else - it's a world on the move."
Cloppity cloppity clop.
It's done with coconuts. A river of fire ants crossing the jungle floor; a wolf spider digging its burrow; why! here's a pantomime horse suffering from a demarcation dispute which may effect its breeding chances. All coconuts.
