Many migratory seabird species are in trouble. Of the 22 species of albatross, 15 are threatened with extinction, while the remaining seven species are near threatened, according the International Union for Conservation of Nature (IUCN). More than half of
all petrel species are threatened with extinction. The most significant threat to these species is from bycatch in longline fisheries, especially from foreign fleets in the Pacific Ocean and illegal, unreported and unregulated fisheries (IUU). Other threats
include marine pollution and invasive predators on nesting islands.
