Petrel parents shunt all experimentally increased reproductive costs to their offspring
Article Abstract:
The impact of control of adult nutritional situations was calculated to examine parent offspring conflict in Oceanodroma leucorhoa employing ptilochronology, and the impact on offspring nutritional situation was calculated by examining chick growth. There was no difference between treatment and control parents in nutritional situation. Treatment chicks acquired mass more slowly and spent a greater part of nights without being fed by either parent. The storm-petrel parents seemingly shunted that cost to their offspring when confronted with an increased cost of parental care.

Experimental evidence for regulation of food delivery to storm petrel, Hydrobates pelagicus, nestlings: the role of chick body condition
Article Abstract:
It appears that the storm petrel provisions food to its chicks based upon the chicks' body condition and appearance of health. Part of a group of chicks being fed by their parents were given supplemental food by researchers, while another part of the group relied for the parents for all of its diet. The parent petrel, soon after some chicks started receiving food from other sources, began to feed that group less. The parent did not know that the group had been receiving food from elsewhere. The total amount of food received by both groups turned out to be very similar.
