This video taken from a webcam by the Scottish Wildlife Trust shows a female osprey named Lady feeding in her nest on the banks of the Loch of the Lowes, a lake in Perthshire, Scotland. Birders were excited about a female osprey who has lived three times longer than average and has faithfully returned to the same Scottish loch for over two decades. Over 130,000 people watched the imposing bird of prey on a webcam the day after she returned to the banks of the Loch of the Lowes, last week. Lady had completed an annual 3,000-mile migration from west Africa to the banks of the same Scottish lake for the 21st consecutive year Photograph: AP

Bluebells at Ashridge near Berkhamsted, Hertfordshire. A mild start to the year is set to produce an early display of bluebells, experts predict. Although last December was the coldest for a century, it was followed by the mildest February for a decade and a mild, dry March, prompting bluebells to start flowering a couple of weeks earlier than normal.
