This blue tit bird has chosen a smelly location for its nest - in a wall-mounted ashtray.

Workers at the Norfolk Carers' Helpline office in the Sprowston Road area are now thinking about christening their new feathered friend 'Benson'.

Signs have been put up asking people not to use the ashtray and the smokers in the office have now had to resort to using an old coffee canister.

Maria Plumb, the helpline co-ordinator, said: 'A couple of months ago there were all these cigarette butts on the ground around the ashtray and I thought it was down to the students who live nearby in a hall of residence.

'Then two weeks ago we noticed that that were some feathers and mess.

'This week I saw the blue tit there and I think there might be some eggs. It certainly seems very comfortable in there.'
