Aln

There has been no new data from Aln’s GSM/GPS transmitter since early on Thursday 9 November, when she was setting out to cross the High Atlas Mountains.

Her southerly course was well to the east of most migration flyways. The image below shows the route taken by UV, now quite experienced. Many ospreys use a similar route across Western Sahara.

Aln’s last roost shown in red, course likely to take her to near or E of the circled area

There will be few cell towers along Aln’s expected path far inland – if she negotiated the High Atlas range successfully. Several days of no data were likely, but by now we should have received some information, even if only a partial upload.

Very sadly, absence of data suggests Aln has not survived. Let’s hope she proves that fear wrong. Ospreys so often amaze us.

    Oh no not another osprey, fingers still crossed for both of them.

  2. Jo says:

    You know me Joanna ……. glass half full …….. Here’s to Aln ………

  3. Ann Norman says:

    No news is hard to take. All fingers crossed. Ann

  4. Starling says:

    Oh no, please not Aln! I always hope for tracker failure of some kind. Would be awful to have lost them both.

  5. Vivien Finn says:

    Really hoping for some good news for you, Joanna. Thoughts are with you.

  6. Gerry Valliere says:

    This is not a case of ‘no news is good news’. Still hoping for the best.

  7. P Gilson says:

    So sad. Hope she makes a miraculous reappearance.

  8. Sal Lloyd says:

    Could she have gone even further east, perhaps? There is at least one osprey (No. 14 from the LDOP) who has been tracked overwintering in Bioko for the last few years, which is way east of the usual wintering grounds……

      It is unlikely, Sal, in Aln’s case. The winds in the first part of the week were from the east, hence the circle on the image in the post being somewhat west of Aln’s course on 8 November.

      • Sal Lloyd says:

        Thanks for the reply Joanna, just trying to hold onto any possible explanation for her disappearance. Hard to believe she has endured the twists and turns she has, then made a conscious decision to stay put in Spain to maybe build up her reserves, went South again seemingly quite suddenly but with good progress, only to perish soon after. Very sad if this is the case, but I’ll give her a few more days to show that it isn’t.
        I suppose with only 30-40% of ospreys surviving their first year, the reality is starkly illustrated on tracking.

  9. joannadailey says:

    Aln was on the main flyway, then on 8 November went S, rather than continued SW. Unfortunately, that was probably not a good decision – higher mountains, deeper into the desert – although as you say she has made many sound ones too.

    I’m hoping too, naturally, but the lack of data is a significant concern.

  10. Vic Paine says:

    Unfortunately that is the catch 22 of tracking Ospreys, only a few are tracked so they are closely followed and any losses are keenly felt. The upside is that we have an immense amount of data on Osprey migration. It is thanks to the dedication of Joanna and Paul that we know so much about the migration of Kielder Ospreys.

  11. I’m so so sorry. All one say is that we’ve had bird whose transmitter failed in the summer turn up six month’s later, so finger’s crossed.

  12. Mike Simmonds says:

    Vic sums it up so correctly. Sometimes the reasons are established but many times they are not. Phil’s point is equally valid and it is that view which provides some hope.
    Thank you Jaydee and Paul for all your work and updates.
