Predator defense is shaped by risk, brood value and social group benefits in a cooperative breeder

Niki Teunissen, Sjouke Kingma & Anne Peters
Predation is a major cause of mortality and nest failure in birds. Cooperative predator defense can enhance nest success and adult survival, but since it is inherently risky, dynamic risk assessment theory predicts that individuals modify defense behavior according to risk posed by the predator. Parental investment theory on the other hand predicts that reproductive payoffs (brood value) determine investment in nest defense. We propose that in cooperative breeders, fitness benefits deriving from survival of...
