Hummingbirds Jewelled Messengers

Rockport, Texas is being invaded: 14 million Ruby-throated hummingbirds fly into this suburb of Corpus Christi in a period of 48 hours. They are about to undertake the most remarkable journey, flying non-stop over 1,000 kilometres across the waters of the Gulf of Mexico. The trip will take 25 hours without a possibility to pause.
