The explanation for birds moving on even when there are still seeds left is based on the principle of optimal foraging theory. This theory suggests that animals, including birds, will forage in a manner that maximizes their net energy intake per unit of time. When the density of food (in this case, seeds) becomes too low, the energy expended to find and consume the remaining seeds may not be worth the energy gained from eating them. Therefore, the birds move to a new area where food is more abundant, and they can forage more efficiently.
