“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.”
