Predation imposes strong selection on the expression of a multitude of avian life history traits as well as habitat selection decisions. Recent studies have even shown that many species of wadding birds and some species of passerines migrate at times and in places that differ from that of migrating raptors. Yet despite the apparent importance of predation, little is known about how predation shapes where individual choose to stop during migration. We hope to develop experiments that examine the role of predation in shaping habitat selection decisions during migration.
