When you lift the bonnet of a tractor you would ordinarily expect to hear the roar of an engine rather than the chirping of chicks.

But the latter sounds is what filled the ears of Upper Sheringham man Jon Dorey, who found five baby blackbirds nesting on top of the exhaust manifold in one of the tractors on his property.

Mr Dorey, who runs a joinery business, said: "There sat five little blackbirds - I couldn't believe it when I saw it. I needed to use that tractor, but luckily I've got another one exactly the same so I parked it up next to it and gently moved the nest.

"They've now got their eyes open, their mother has been feeding them and they look ready to fledge."

Mr Dorey said he would continue to keep an eye on the birds to make sure they were OK.

It follows the discovery of another unusual nesting spot in north Norfolk - a bird has taken up residence inside a letter box in Bodham.
