Taxonomy

Order	Procellariiformes
Family	Diomedeidae
Genus	Phoebetria
Species	P. fusca

Order       Procellariiformes

Family     Diomedeidae

Genus     Phoebetria

Species   P. fusca

The genus Phoebetria was created by Reichenbach in 1853, but included only one species, P. fuliginosa.  Although the Sooty Albatross (P. fusca) was first collected in 1822 and the similar Light-mantled Albatross (P. palpebrata) in 1795, it was not until 1913 that Cushman Murphy revised the genus to include both P. fusca and P. palpebrata ^[1 ]. More recent analyses of complete mitochondrial cytochrome-b gene sequences have confirmed the placement of both species within this genus ^{[2 ]}.

Breeding Biology

Phoebetria fusca is a biennial breeder and lays a single egg with no replacement laying.  This species nests solitarily or in small colonies or clusters, building pedestal nests along sheltered cliff edges ^[18, 19 ].  Birds show high fidelity to nesting colonies and arrive on Marion and Gough Islands and Iles Crozet in late August but one month earlier at the main group of Tristan da Cunha Islands.  Egg laying ranges from mid-September to late October (Table 1), although synchronised within each colony, and incubation duties are shared ^{[19 ]}.  Eggs hatch in early to mid-December after incubation periods averaging 70-71 days (range 66-71 days on Iles Crozet ^{[18 ]} and 69-73 days on Marion Island ^{[19 ]}); chicks are brooded for an additional 21 days.  On Iles Crozet, the average age of first breeding is 11.8 years ^{[20 ]}.  Chicks fledge in May.
