Albatrosses are among the most impressive birds whether you’re considering size, flight duration or life conditions. Albatrosses feed mainly on squids and fish that they catch at the surface of the Southern ocean, days and nights.

We overlaid here the path of an albatross tracked using Argos (H. Weimerskirch, CNRS/CEBC) with micronekton biomass every seven days, using the epipelagic, migrant and highly migrant variables of the Seapodym model (meaning either the micronekton living at the surface or near, the one migrating to the surface from intermediate and from deep layers at night).

This particular albatross seemed to stay in regions of higher micronekton biomass most of its round-the-globe trip (lasting about six months). Such comparisons can help to understand why and where we can find those predators, and thus try toprotect them.
