for details. It
certainly moved around the area with daily
locations up to 50 km apart, for example on 29/9 it
moved about 30km inland and was a similar distance
out over the Atlantic on 1/10. The position on 5/10, out to
sea, seems to have been the start of an onward
migratory flight. The location plotted on 6/10
indicates a movement of 873km in 28
hours. After a short stopover on the
coast south of Lisbon, he flew another 432km on
13th to reach Africa. Since then, R03's apparent
preference for coastal fishing seems to have been
abandoned. On 17th he crossed the Atlas Mts where
they are over 3000m high. The flight SE into
Algeria and then across Mali and eastern Mauritania
has taken R03 into some of the most desolate parts
of the Sahara. On 26/10, R03 entered the
region of Mali known as the Sahel and reached the
headwaters of the River Niger. We received
locations every 11 days or so throughout the winter
and spring but always from exactly the same spot.
No further movements were recorded and eventually
the radio transmitter produced no useful
data. |
