An object of class MoveStack
The vultures data comes from a study about search efficiency of vultures foraging on spatio-temporally unpredictable carcasses in the Etosha National Park in Namibia.
The MoveStack
object vulture_moveStack
represents a subset of the original
data set downloaded from movebank and contains trajectory data of three vulture individuals,
named X1 (Gyps africanus), X2 (Torgos tracheliotus) and X3 (Gyps africanus).
The permission to use the data was obtained from the owners of the data (Contact person: Orr Spiegel).
