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.
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.
