As Kayleigh reported earlier today, things have been turning distinctly autumnal at Rutland Water in the past few days. One by one the Ospreys have been heading south, and we now know that our satellite-tagged bird, 30(05) is one of them. The latest data from her satellite transmitter shows that at 6am this morning, 30 was in northern Spain, 20 kilometres to the east of San Sebastiàn having set-off from Rutland on Sunday morning.
We don’t know exactly what time 30 left the Rutland Water area on Sunday, but it must have been fairly early because at 10am her transmitter showed that she was in northern Buckinghamshire, midway between Banbury and Milton Keynes, flying purposefully south at an altitude of 550 metres. She made excellent progress over the next four hours, continuing south through Oxfordshire, Berkshire and Hampshire at altitudes of between 500 and 1000 metres. By 2pm she had flown 151 km in four hours and was 1230 metres above the Isle of Wight with the English Channel in her sights. She made light work of the crossing to France and by 6pm GMT she was flying south through Lower Normandy. She eventually settled to roost for the night on the edge of a small wood, 55km west of Le Mans after a day’s flight of at least 520 kilometres.
Next morning 30 was on the move at first light because at 7am local time (6am GMT) she was already 46km south of her overnight roost site, and was flying due south at 31kph. She paused briefly on the edge of a small copse at 8am, but by 9am she was on the wing again, passing over the River Loire soon afterwards. Four hours later she was passing just to the west of La Rochelle at an altitude of 1500 metres. She had already covered 210 kilometres but was showing no signs of letting-up. Using the west coast of France to guide her, 30 flew another 290 kilometres during the afternoon and by 7pm she was just north of the town of Capbreton in the south of France. On Google Earth the area around Capbreton looks good for fishing and by 9pm 30 had settled for the evening in a forested area just north of Ondres having almost certainly caught a fish in one of the nearby lakes. Over the course of the day she had flown another 510 kilometres; another excellent day’s migration.
This morning 30 was on the move early again. Like the previous day, she had already flown another 40km by 7am local time, passing Biarritz and then across the Spanish border. By this evening she may well be close to Madrid. It will be fascinating to see how far she has flown when the next batch of data comes in.
