Balearic Shearwater

The Balearic Shearwater (Puffinus mauretanicus) is a species in the genus Puffinus. Typically found in various aerial, terrestrial, and aquatic environments. Like other members of its genus, this species plays a role in its native ecosystem.

Christmas Shearwater

The Christmas shearwater (Puffinus nativitatis) is a medium-sized seabird in the family Procellariidae, distributed across the tropical Pacific Ocean. It is entirely dark — sooty brown to black — with no contrasting pale underparts, distinguishing it from most other shearwaters. The species breeds on tropical Pacific island groups including the Hawaiian Islands, Johnston Atoll, the Phoenix Islands, the Line Islands, and several other central Pacific atolls, nesting in coral rubble, dense vegetation, or rock crevices. Like other shearwaters, it is a pelagic species that spends most of its life at sea, foraging for fish and squid in tropical Pacific waters. Christmas shearwaters fly with stiff, shearwater-style wing beats interspersed with gliding, following wave contours close to the ocean surface. Breeding colonies are vulnerable to introduced predators such as rats and cats, which have severely affected many Pacific seabird colonies. The species is generally considered stable within its extensive oceanic range, though individual island populations can be threatened by predator incursions. Conservation of Pacific island nesting sites through invasive mammal eradication programs has benefited this and many other tropical seabird species.
