Goose photographed flying upside down

Paul Stancliffe, of the British Trust for Ornithology, based at Thetford, was able to explain the bird's bizarre behaviour.

"It looks like this bird is in mid-whiffle," he said.



"When geese come in to land from a great height they partake in a bout of whiffling, this involves the bird twisting and turning to spill air from their wings and thus lowering their speed prior to landing.

"In 36 years of birdwatching I have seen this many times, particularly when watching pink-footed geese on the north Norfolk coast coming in to roost in the late afternoon and evening. I have, however, never seen a photograph of a bird in mid-whiffle like this. It is an amazing photograph."
