Justification:
This species is classified as Near Threatened as it may be declining at a moderately rapid rate, owing to bycatch on longline fisheries and perhaps the impacts of introduced predators. Threats and population status both remain poorly known.

Geographic Range [top]

Range Description:	Phoebetria palpebrata has a circumpolar distribution in the Southern Ocean. It disperses over cold Antarctic waters in summer as far south as the pack ice (Weimerskirch and Robertson 1994) but ranges north into temperate and sub-tropical seas in winter. It breeds on South Georgia (Georgias del Sur), Auckland, Campbell and Antipodes islands (New Zealand), Amsterdam, St Paul, Crozet and Kerguelen islands (French Southern Territories), Heard Island (Heard and MacDonald Islands (to Australia)), Macquarie Island (Australia), and Prince Edward and Marion islands (South Africa).
Countries:	Native: Antarctica; Argentina; Australia; Chile; Falkland Islands (Malvinas); French Southern Territories (the); Heard Island and McDonald Islands; New Zealand; South Africa; South Georgia and the South Sandwich Islands Vagrant: Brazil; French Polynesia; Mauritius Present - origin uncertain: Bouvet Island

Population [top]

Population:	Information on population status and trend is most well known on Possession Island (Crozet Islands), where there were 916 pairs in 2006 (Delord et al. 2008) There are c.1,949 pairs in the Crozet group, 1,250 pairs on Macquarie Island (ACAP 2012), 5,000-7,500 pairs on South Georgia, 3,000-5,000 pairs on Kerguelen, c.5,000 pairs on the Auckland Islands, at least 1,600 pairs on Campbell Island, 170 pairs on the Antipodes Islands, 200-500 pairs on Heard Island (Croxall and Gales 1998; Taylor 2000), and 350 pairs on Marion Island and 129 pairs on Prince Edward Island (ACAP 2012). The total annual breeding population is estimated at 19,000-24,000 pairs, roughly equivalent to 58,000 mature individuals (and 87,000 individuals in total) in this biennially breeding species - Croxall and Gales (1998) estimated c. 21,600 pairs.
Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	Behaviour This species is a biennial breeder usually nesting solitarily or in small colonies. Most eggs are laid in October-November, hatch in December-January and chicks fledge in May-June (Croxall and Gales 1998). Egg laying is highly synchronous within each colony. Young birds are philopatric, returning to their natal colonies after 7 to 12 years (ACAP 2009). Breeding birds from Macquarie Island typically forage in shelf waters around the island; they also utilise sub-Antarctic and Antarctic waters south-west of Macquarie (BirdLife International 2004). During chick-rearing, adults from South Georgia feed in Antarctic shelf and shelf-slope areas along the southern Scotia Arc and to a lesser extent in oceanic waters in the mid Scotia Sea (Phillips et al. 2005). It employs a variety of feeding strategies, including surface-seizing, surface filtering and plunging. Habitat Breeding It nests on cliff ledges, on a pedestal nest of mud and peat, lined with grass. Diet The diet is primarily composed of cephalopods and euphausiids, but birds also take fish and carrion (Thomas 1982, Cooper and Klages 1995). Foraging range Five satellite-tracked incubating birds from Macquarie Island foraged south of the Antarctic Polar Front, an average of 1,500 km from their breeding sites. Four breeding birds from South Georgia (Islas Georgias del Sur) followed a typical flight path (38 trips) involving a clockwise route to and from high latitude waters along the southern Scotia Arc, on average travelling 3,800 km, to a maximum range of 920 km from the colony (ACAP 2009).

Threats [top]

Major Threat(s):	Reports from New Zealand, Australia and Japan indicate that it is caught in tuna longline fisheries (39 returned from observers in New Zealand fisheries in 1996-2005, but only three since 1996) (C. J. R. Robertson in litt.2008), although data on bycatch are sparse compared to other albatross species. Introduced predators are present at all New Zealand colonies except Campbell Island and they may affect breeding success and colony distribution (Taylor 2000). Cats also affect breeding success on the Kerguelen Islands (ACAP 2009).
