Progress of our satellite tagged birds

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.

    More great news about the tagged Ospreys everywhere. It seems to have been a comparatively good year for Autumn migrations in 2019.
    Well done those Ospreys 🙂

    Is there any news on Blue 30 or does she have a faulty transmitter.

    1. Katy Smart

      Hi Sue, we can confirm Blue 30 is alive and well. Her transmitters unfortunately is no longer sending location data to us. Most transmitters have an average lifespan of a few years and we were very lucky as her transmitter had already been used on another osprey! However, we still have osprey migration information of two Rutland males S1 and 4K that we know have arrived at their overwintering grounds safely. Many thank, the osprey team.

    I am so pleased that they have both arrived safely. I thought two ospreys were satellite tagged in 2018?

      Hi Wendy, the two male ospreys S1 and 4K from Rutland Water were fitted with satellite transmitters in 2018. It is lovely to see they have arrived safely at their overwintering grounds. Many thanks, the osprey team.
