He doesn't scoff all the best bits and he rarely interrupts the conversation.
So Robby the rabbit is more than welcome at the rhino dinner table.
The 2lb bunny has become a daily visitor to the white rhinoceros compound at the Western Plains Zoo in New South Wales, Australia.
Though tentative on his first few trips, he now hops straight up to two-ton Umquali - and her ferocious-looking horn - when the morning meal arrives.

He waits until Umquali gets his supply of hay before bobbing through the fence and joining his huge friend for a shared meal.
Robby leaves the hay to her and the rest of the herd and nibbles at the seeds that drop down.
Zoo keeper Kevin Milton said:'It's quite a sight to see this little furry thing tucking into food beside the rhino with its tough skin.
'You usually find some bird or rabbits hanging around trying to get the seed that's in the rhino feed.'
But Robby has shown he has more courage than the rest of the colony of rabbits which live in the surrounding plains, venturing closer each day until deciding that the massive beast isn't going to cause him any serious damage.

Umquali has been in the spotlight at the zoo in recent months since giving birth in April to a calf named Nadira, making it the sixth rhino to be born in the zoo's white rhino breeding programme.
It began in 2003 when the species was brought from the Kruger National Park in South Africa.
Already Nadira is piling on the pounds. Weighing 'only' 8 stone at birth, she now stands at around 32 stone.

'Her mother is a very dominant female in the herd and Nadira uses that to her advantage,' said Mr Milton.
'In a feeding frenzy Nadira pushes the other rhinos around and usually gets away with it. But once they object, Umquali the mother steps in.' Except, of course, if a little rabbit called Robby happens to drop by for a snack.
That's when Umquali stops throwing her weight around and welcomes him to the 'table'.
