Not much movement

Well, since the last post...

• 130393 has moved a bit SW to near Wau on the 21st then SE to near Riani, South Sudan. That brings it back near to where it was on 13 November.  
• 130394 is presumably well in South Sudan, and we are waiting for new data.
• We still have not heard from 130395. It has missed three transmission cycles. We are working with Saudi collaborators to gather more information.
• 130396 is also worrying us.  It has missed 1 transmission cycle and was last heard over the Red Sea about 60 km from the African mainland at about 1900 hrs.
• 130397 is still hanging around the Eritrean coast south and east of Asmara.

Movements of migrating sooty falcons 12-22 November 2013

It is interesting to note that the migration pattern of sooty falcons tracked by us and Dr. Marion Gschweng in 2010 (http://sootyfalconoman.blogspot.co.at/) is similar to what we seem to be seeing. Birds seem willing to stop and wander around areas instead of constantly pushing south.  Presumably this is because while migrating the birds encounter good foraging conditions and just decide to take advantage of them.   So far the migration paths of the birds since they have been in Africa are different that the birds tracked in 2010, which may suggest that sooty falcon migration does not concentrate at any locations.  As far as we are aware no concentrations of migrating sooty falcons have been reported
