UV, one very interesting Osprey

There was another data drop from UV late today, again unexpected given lack of cell towers in Western Sahara. But as soon as the data file opened it was clear how this had happened. He has gone nowhere! Here is an image of him today.

That northern part of the bay is the area fish are most likely to be. His decision to stay could be wise because there is a large dust storm (equalization event in techspeak) in the mid Sahara. Thanks to Paul for this info.

Also today the backfill data on his journey from Portugal downloaded. Here is his sea crossing.

He flew non stop over ocean for just over 24 hours. And covered about 1100 km. But he didn’t pause when he reached Africa, carrying on (with possibly one very brief halt at 14.48) until 16.49 GMT.  He then roosted on the desert floor until sometime after 10.00 on 9 December when he set off again flying without a break (as far as quite frequent fixes show) until 15.50 when he had a half hour stop in the desert, then he flew a bit further before finding an overnight roost. Here is an image of the area.

The rest is history, as they say. He left the roost area at soon after 10.00 and was within range of a cell tower later that day which is when we first knew he had reached Africa.

The final image shows his overall travel from leaving Portugal until tonight. In that time he has flown about 2000 km.

    This really is fantastic data. Makes it feel as if we are flying with him almost.

    Very Interesting – A food stop at Dakhla or another stop over or the end of the journey.
    Google Images has many pictures of the area and bay.

      Keith, although some of the photos on Google Earth claim it is Dakhla, that is actually further up the coast. UV’s area is within a large bay, the Gulf of Cintra. There’ll be more about it in the next post.

        Many Thanks Joanna – Found the area (Gulf of Cintra) – an area many wintering sea birds frequent.
        Not far north from the Mauritania border and National Park of Banc D,Arguin where many ospreys visit for the winter (A few hours flight for UV).
        Look forward to your next post – so educational as well as the news of our ospreys.
