| experimental evidence for innate predator recognition in the seychelles warbler. | nest predation is a major determinant of fitness in birds and costly nest defence behaviours have evolved in order to reduce nest predation. some avian studies have suggested that predator recognition is innate whereas others have stressed the importance of learning. however, none of these studies controlled for the genetic origin of the populations investigated and the effect of unfamiliarity with the predator. here we determined whether experience with a nest predator is a prerequisite for nes ... | 2000 | 11413640 |
