-Some members of this species may toss eggs in some adverse situations, such as to make space for new eggs when a nest is full or when the egg is unfertilized. Recently, a new event was discovered to trigger egg toss: when predation levels are high and clutch size becomes too small, some gray-capped social weaver parents may toss their eggs as a strategy to maximize its reproductive success, which is alleged to be a new feature in social birds, and is called parental tossing.

+The hypothesis is that the investment in hatching and nurturing the remaining eggs and newborns of the reduced clutch has a high risk of no return, since these newborns may die before hatching or maturing.

+Therefore, the gray-capped social weavers would throw these eggs out and save the energy and resources to the next breed, in which the probability of success is higher, since the new breed would have a higher number of eggs. Another  hypothesis is that, through tossing their eggs, birds are actually removing the main resources of their eggs' predators, keeping its populational sizes under control and possibly enhancing the survival probability of the future clutch.
