    Description: Chile holds globally important colonies of endangered and endemic seabird species, and globally vulnerable nonbreeding species visit its waters. One of the major threats for seabirds in Chilean waters is the impact of fishing activities, both industrial and artisanal, which overlap with seabird breeding and foraging areas. Bycatch in fisheries threatens 27 identified species and two groups of unidentified albatrosses and penguins, with the Black-browed Albatross Thalassarche melanophrys as the species most related to bycatch events. Responding to the international call for the voluntary adoption of a plan to reduce the impacts of fisheries on seabirds, Chile generated a National Plan of Action (PAN-AM/Chile) to monitor seabird bycatch, and to mitigate threats to seabirds with emphasis on industrial longline fisheries. Following the successful reduction of seabird bycatch in the demersal longline fishery for Patagonian toothfish Dissostichus eleginoides , with zero individuals caught during 2006, Chile is extending the PAN-AM/Chile to include other fisheries that use gear known to cause incidental mortality, such as trawl, purse seine, and gillnets. This initiative is supported by actions associated with the creation of a national scientific committee for biodiversity, and new collaborative research platforms under the auspices of the Chilean Undersecretariat for Fisheries and Aquaculture
    Description: Chile cuenta con importantes colonias a nivel global de especies de aves marinas endémicas y en peligro, así como especies no reproductivas globalmente vulnerables que visitan sus aguas. Una de las mayores amenazas para las aves marinas en aguas chilenas es el impacto de las actividades pesqueras, tanto industriales y artesanales, las cuales se sobreponen con áreas de reproducción y alimentación de aves marinas. Estas amenazan 27 especies identificadas y dos grupos de albatross y pingüinos no identificados, con el Albatros de ceja negra Thalassarche melanophrys como la especie más relacionada a eventos de captura incidental. Respondiendo al llamado internacional para la adopción voluntaria de un plan para reducir los impactos de las pesquerías en aves marinas, Chile generó un Plan de Acción Nacional (PAN-AM/Chile) para monitorear la captura incidental de aves marinas y mitigar amenazas con énfasis en pesquerías industriales de palangre. Seguido a la exitosa reducción de la captura incidental en la pesquería demersal de palangre para Bacalao de profundidad Dissostichus eleginoides, con cero individuos capturados durante 2006, Chile está ampliando el PAN-AM/Chile para incluir otras pesquerías que usan artes de pesca con conocida mortalidad incidental, tales como arrastre, cerco y redes agalleras.

    Notes: Summary Water and sodium turnovers of 6–7 week old gentoo penguin chicks and breeding adults were measured using isotopically labelled water and sodium. Influx rates for chicks averaged 188 ml·kg-1·day-1 and 13.9 mmol·kg-1·day-1 for water and sodium, respectively. Chicks consumed an estimated 228 g·kg-1·day-1 fresh food or 886 kJ kg-1 day. These values correspond to 761 g·day-1 or 2945 kJ·day-1 for a gentoo chick mid-way through the growth period. Flux rates for adults attending chicks ranged from 199 to 428 ml·kg-1·day-1 for water and from 15 to 36 mmol·kg-1·ay-1 for sodium.

    Notes: Abstract The diet composition of king penguins (Aptenodytes patagonicus) at Heard Island (53°05′S; 73°30′E) was determined from stomach contents of 98 adults captured as they returned to the island throughout 1992. During the two growth seasons, the diet was dominated by the myctophid fish Krefftichthys anderssoni (94% by number, 48% by mass). The paralepidid fish Magnisudis prionosa contributed 〈1% by numbers but 17% by mass. Mackerel icefish (Champsocephalus gunnari) accounted for 17% by mass of chick diet in late winter, when chicks were malnourished and prone to starvation, although its annual contribution to the penguins' diet was only 3%. Squid was consumed only between April and August; Martialia hyadesi was the commonest squid taken, comprising 40–48% of the winter diet. The remainder of the diet consisted of the squid Moroteuthis ingens and fish other than K. anderssoni. The energy content of the diet mix fed to the chicks varied seasonally being highest during the growth seasons (7.83 ± 0.25 kJ g−1) and lowest in winter (6.58 ± 0.19 kJ g−1). From energetic experiments we estimated that an adult penguin consumed 300 kg of food each, of which its chick received 55 kg during the 1992 season. The chicks received large meals at the beginning of winter (1.2 ± 0.3 kg) and during the middle of the second growth season (1.2 ± 0.3 kg), and their smallest meals in late winter (0.4 ± 0.1 kg). The gross energy required to rear a king penguin chick was estimated to be 724 MJ. The potential impact of commercial fisheries on the breeding activities of king penguins is discussed.

    Notes: Abstract The diving and foraging behaviours of Adélie penguins, Pygoscelis adeliae, rearing chiks at Hukuro Cove, Lützow-Holm Bay, where the fast sea-ice remained throughout summer, were compared to those of penguins at Magnetic Island, Prydz Bay, where the fast sea-ice disappeared in early January. Parent penguins at Hukuro Cove made shallower (7.1–11.3 m) but longer (90–111 s) dives than those at Magnetic Island (22.9 m and 62 s). Dive duration correlated with dive depth at both colonies (r 2 = 0.001 ∼ 0.90), but the penguins atg Hukuro Cove made longer dives for a given depth. Parents at Hukuro Cove made shorter foraging trips (8.1–14.4 h) with proportionally longer walking/swimming (diving 〈 1 m) travel time (27–40% of trip duration) and returned with smaller meals (253–293 g) than those at Magnetic Island, which foraged on average for 57.2 h, spent 2% of time walking/swimming ( 〈 1 m) travel, and with meals averaging 525 g. Trip duration at both colonies correlated to the total time spent diving. Trip duration at Hukuro Cove, but not at Magnetic Island, increased as walking/swimming ( 〈 1 m) travel time increased. These differences in foraging behaviour between colonies probably reflected differences in sea-ice cover and the availability of foraging sites.

    Notes: Abstract The seasonal variation in the foraging behaviour of king penguins (Aptenodytes patagonicus) was studied at Heard Island (53°05′S, 73°30′E) during 1992/1993. On seven occasions throughout the breeding cycle, time-depth-light recorders were deployed on breeding adults to record the dive activities and foraging. Foraging locations changed with season: in autumn and spring 1992, adults foraged between 48–52°S and 74–78°E, about 370 km NNE of Heard Island close to the Polar Front. Two penguins tracked in winter travelled 2220 km east of Heard Island (95°E) along the northern ice limit, and 1220 km south of Heard Island to approximately 65°S, respectively. In spring (October), the penguins again foraged further north than during winter. The foraging area utilised in October overlapped the area where the penguins foraged in March/April. The penguins' diving behaviour also varied seasonally: the modal depth of deep dives (〉50 m) increased from about 100 m in February to 220 m in October. Mean dive depths increased from 70 ± 52 m in March 1992 to 160 ± 68 m in August 1992. Penguins dived deep (〉50 m) only during daylight hours (16 h in February, 9 h in July). Mean dive durations ranged from 2.9 ± 1.1 min in March 1992 to 5.1 ± 1.2 min in August 1992. Associated with changes in foraging location and dive behaviour was a change in diet composition: during summer the penguins ingested mainly myctophid fish (〉90%) while in winter the most important diet item was squid.
