In a songbird species, defending a territory saved the bird 584 calories a day in reduced foraging activity, but cost the bird 656 calories in defense of the territory. Is defending the territory consistent with the prediction from optimal foraging theory, and what can explain this?
A. Yes, because a bird of this species will minimize predation risk by defending the territory. B. No, but there may be non-nutritional benefits to defending territory. C. No, so it is likely that the researcher made a mistake in data collection. D. No, so that demonstrates that optimal foraging theory is not useful. E. Yes, because the bird will save 72 calories per day due to defending the territory.
