1. The benefits of helping behavior to recipients were studied by analyzing the factors that influence rates of feeding of nestlings by parents and helpers in Pomatostomus temporalis. 2. Considering the nestlings as recipients, no benefits were detected from helpers that would not have been received from the parents alone: total feeding rate was independent of the number of helpers. Total feeding rate was dependent on the energy needs of the nestlings and on environmental factors, such as… CONTINUE READING
