Most albatrosses and procellariids use two techniques to minimise exertion while flying, namely, dynamic soaring and slope soaring. The albatrosses and giant petrels share a morphological adaptation to aid in flight, a sheet of tendon which locks the wing when fully extended, allowing the wing to be kept up and out without any muscle effort.

The genus Pseudobulweria was introduced in 1936 by the Australian born ornithologist Gregory Mathews with the Fiji petrel as the type species.Mathews suggested that petrels in his new genus Pseudobulweria had longer wings than those in Bulweria: "In Bulweria the wing measurement is less than twice the tail measurement; in Pseudobulweria the wing measurement is more than twice that of the tail."
