What critical factor regarding prey intake is deemed more important than the volume consumed daily for sustained flight?

The quality and density of the squid and fish in their diet

The foraging success of the Wandering Albatross is fundamentally linked to energy maximization per unit of effort, given their phenomenal energy conservation during flight, often achieved through dynamic soaring across thousands of kilometers. Because their energy expenditure during sustained flight is extremely low relative to the potential caloric gain from a successful meal, the importance shifts from sheer volume to caloric density. A diet rich in fatty organisms, such as oily fish and squid, provides far more calorically dense energy, which is efficient for long-haul navigation and can be converted into stored stomach oil, making quality paramount over quantity in daily intake.
