We are delighted to report that our ospreys with satellite tags, 4K(13) and S1(15) are both in their wintering grounds in West Africa, the map outlines S1’s route over the Sahara Desert.
The desert’s vast and desolate expanse presents a demanding challenge to all our migrating birds. They will typically take a westerly route from southern Morocco, through Western Sahara arriving in northern Senegal up to five days later. Because of satellite technology, we now have a better understanding of their journeys. They migrate across the desert using a soaring and gliding flight, using strong thermals to gain altitude, gliding onwards, then slowly losing height before they reach the next updraft. This method conserves their energy. Remarkable.
