Divergent post-breeding spatial habitat use of Laysan and black-footed albatross

Frontiers in Ecology and Evolution, 2022
Understanding the at-sea movements of wide-ranging seabird species throughout their annual cycle is essential for their conservation and management. Habitat use and resource partitioning of Laysan (Phoebastria immutabilis) and black-footed (Phoebastria ...
