In February 2020 we trapped seven adult Egyptian vultures at the Tadjoura abattoir, and fitted them with GPS loggers. Of the seven, at least six seem to be still active in March 2021. One may have died, but may still be alive, but outside the GSM network. It may also have dropped its tag. The birds displayed different patterns of behaviour. Some appeared to settle into territories, others wandered widely, and at least one seemed to settle for rather short periods in areas, then move on (See maps below). Their use of the abattoir at which they were captured varied: some birds visited regularly, some irregularly, some rarely.
The ranging of the birds overlapped considerably (maps below), which is to be expected from scavenging birds, even though many birds were tied to territories.
