Individual characteristics include whether or not high rank gives them access to valuable resources such as mates and food. High-ranking males have more access to fertile females and consequently partake in most of the matings within the group; in one population, three males were responsible for over 75 of matings. Thus, individuals with higher social status tend to have greater reproductive success by mating more often and having more resources to invest in the survival of offspring.

The elder, stronger chick almost always becomes the dominant chick. 46 In some ant species such as the carpenter ant Camponotus floridanus, eggs from queens have a peculiar chemical profile that workers can distinguish from worker laid eggs. 30 This is in stark opposition to the original suggestion stating that being subdominant was more stressful than being dominant within a hierarchy.

During times of food shortage, the dominant chick often kills the subordinate chick by either repeatedly pecking or by ousting the younger chick from the nest.

Functional Importance of Plumage Badges as Intraspecific Signals in White-Crowned Sparrows (zonotrichia Leucophrys Oriantha) : Deep Blue at the University of Michigan. Since nuptial flights are seasonal and workers are wingless, workers are almost always virgin, and (as gamergate ants or laying worker bees ) can only lay unfertilised eggs.
