east wind better for Marsh Harrier


















this 2cy male Marsh Harrier is a real beauty -- but in addition it has a strange hunting technique in that it flies along cold searching in typical harrier manner then it suddenly stalls and goes almost vertical , tail down and wings up a bit like a hovering Osprey but it continues to do this every 20 - 40m while passing over the reedbeds though it seldom even drops down as if to strike --a search mechanism but seems to be energy inefficient -
