What common upper range for the wingspan of the Wandering Albatross is referenced when discussing foraging efficiency?

Answer

3.5 meters

The physical attributes of the Wandering Albatross, specifically its massive wingspan, directly influence its energy conservation strategy during foraging over vast oceanic distances. While the text notes the maximum recorded wingspan is nearly 11 meters, it specifies that the more common upper range frequently referenced in discussions of flight efficiency and energy expenditure calculations is 3.5 meters. This large span allows for phenomenal energy conservation during gliding, meaning that the caloric density of the food they consume must be high enough to sustain a lifestyle that requires covering thousands of kilometers between successful feeding bouts.
