Stunning pictures have emerged of Nico the gorilla getting in a strop with an unwanted visitor to his island at Longleat safari park in Wilthsire.

Europe’s oldest gorilla ended up getting his feathers well and truly ruffled after the bizarre confrontation with a stroppy goose.

Nico, a silverback lowland gorilla, who's about 55, clearly didn’t take kindly to a pair of Canada geese who attempted to invade his island home at Longleat Safari Park.

The amazing encounter was captured on film by amateur photographer Michael Metchen during a visit to the Wiltshire safari park.

He describes what happened.

I was on the Jungle Cruise boat and as we got to Nico’s island, I couldn't see him; but there were a couple of geese there.

It seems Nico isn't too good at controlling his temper.

Although he is now a very old man, Nico is still extremely active and in amazingly good condition.
