Optimal foraging theory proposes that animals obtain the highest rate of reinforcers for the least effort and momentary … behavior that was biased towards the weighted alternative, yet the bias was less than that predicted by optimal foraging theory … reinforcers earned per-visit and included elements of optimal foraging and momentary maximizing theories of choice. …

The likely factor limiting their foraging activity is finding their nest entrance on return from a foraging trip. The …, they leave the nest at dimmer light levels in the morning than in the evening.
