Laziness - Animals

Animals

It is common for animals (even those like hummingbirds that have high energy needs) to forage for food until satiated, and then spend most of their time doing nothing, or at least nothing in particular. They seek to "satisfice" their needs rather than obtaining an optimal diet or habitat. Even diurnal animals, which have a limited amount of daylight in which to accomplish their tasks, follow this pattern. Social activity comes in a distant third to eating and resting for foraging animals. When more time must be spent foraging, animals are more likely to sacrifice time spent on aggressive behavior than time spent resting. Extremely efficient predators have more free time and thus often appear more lazy than relatively inept predators that have little free time. Beetles likewise seem to forage lazily due to a lack of foraging competitors. On the other hand, some animals, such as pigeons and rats, seem to prefer to respond for food rather than eat equally available "free food" in some conditions.
