  abstract = {{U}nderstanding the at-sea movements of wide-ranging seabird species throughout their annual cycle is essential for their conservation and management. {H}abitat use and resource partitioning of {L}aysan ({P}hoebastria immutabills) and black-footed ({P}hoebastria nigripes) albatross are well-described during the breeding period but are less understood during the post-breeding period, which represents similar to 40% of their annual cycle. {R}esource partitioning may be reduced during post-breeding, when birds are not constrained to return to the nest site regularly and can disperse to reduce competitive pressure. {W}e assessed the degree of spatial segregation in the post-breeding distributions of {L}aysan (n=82) and black-footed albatrosses (n=61) using geolocator tags between 2008 and 2012 from two large breeding colonies in the {N}orthwestern {H}awaiian {I}slands, {M}idway {A}toll, and {T}ern {I}sland. {W}e characterized the species-and colony-specific foraging and focal distributions (represented by the 95 and 50th density contours, respectively) and quantified segregation in at-sea habitat use between species and colonies. {L}aysan and black-footed albatross showed consistent and significant at-sea segregation in focal areas across colonies, indicating that resource partitioning persists during post-breeding. {W}ithin breeding colonies, segregation of foraging areas between the two species was more evident for birds breeding at {T}ern {I}sland. {S}patial segregation decreased as the post-breeding season progressed, when spatial distributions of both species became more dispersed. {I}n contrast to studies conducted on breeding {L}aysan and black-footed albatross, we found that sea surface temperature distinguished post-breeding habitats of black-footed albatrosses between colonies, with black-footed albatrosses from {M}idway {A}toll occurring in cooler waters (3.6 degrees {C} cooler on average). {O}ur results reveal marked at-sea segregation between {L}aysan and black-footed albatross breeding at two colonies during a critical but understudied phase in their annual cycle. {T}he observed variation in species-environment relationships underscores the importance of sampling multiple colonies and temporal periods to more thoroughly understand the spatial distributions of pelagic seabirds.},
