摘要

The BBC astounded the world with its revelation early last year that the Adelie Penguin had evolved to take flight in the Antarctic region around McMurdo Sound. Further research by workers studying the effects of global warming in the area has led to the astonishing discovery of a larger framed and heavily feathered cross breed (Aptenodytes foresteri X Pygoscelis adelie) for which a northbound migration has just become evident. It is believed that the warmer Antarctic summer, now so familiar through screening of ice flow break-up, has forced this genetic mutant to over summer in the Northern hemisphere.rnQuite why these migrants make first landfall on the Channel Island of Jersey is as yet unknown but local ornithologists suggest it may be the reflection of the lights at St. Helier Bay attracting the weary birds to land, albeit on the colder north beach at Greve de Lecq. After a few days recovery between Boxing Day and New Year the congregation can be seen massing and wheeling in the still air at sunrise before re-grouping astern the red-eye flight heading for Southampton, Eastleigh, birthplace of the Spitfire.
