Abstract
Spatio-temporal patterns of predator aggregations within their
settlement areas (i.e. temporary settling zones used during dispersal
or, more generally, foraging patches) were studied. By integrating the
main behavioural rules of juveniles of Spanish imperial eagles Aquila
adalberti during dispersal with the temporal availability of the eagles'
main prey, we have developed several individual-based models under
different simulation scenarios. The results suggest that the spatially
synchrony of the aggregation patterns that we observed were derived from
a combination of behavioural responses of the prey and the distances
between available settlement areas. These results are discussed in the
context of predator-prey relationships, optimal foraging and
self-organizing processes.
