Figure 2

Provisioning of nestlings. (a) Provisioning rates of parents to offspring across the three study sites per 30 min. Rates are expressed per nestling, that is, number of visits per brood/brood size. (b) Proportions of total provisioned items for different groups of dietary components at each of the three study sites. Data for both panels were obtained from a total of 2 h of video footage combined from 4 different 30-min intervals recorded on the same day.
