Noisy begging by nestlings to be fed by a parent is said to be an honest signal when it entails high costs. And if the begging calls are indeed costly, which of the following predictions is least likely to occur? A. Parents will deliver more food in response to stronger begging. B. A parents will provide more food in response to an offspring that cries the least. C. Noisy crying is more likely to attract the attention of predators. D. Begging intensity reflects the hunger level of the nestlings.
