“…High survival suggests efficient foraging strategies or sufficient foraging opportunities during the immature phase. Yet, juvenile short-tailed albatrosses are still the most vulnerable portion of the population to mortality at sea (Suryan et al 2007, Deguchi et al 2014. This can partially be explained by higher fisheries overlap (Suryan et al 2007).…”

This can partially be explained by higher fisheries overlap (Suryan et al 2007). Adult short-tailed albatrosses forage over both oceanic and neritic habitats across the North Pacific (Hasegawa & DeGange 1982, Suryan et al 2006, concentrating along biologically productive shelf-break areas (Piatt et al 2006), while juveniles appear to use shelf-based habitats more, especially in the Sea of Okhotsk, Bering Sea, and along the US west coast (Suryan et al 2007, Deguchi et al 2014.…”

“…Finally, the breeding frequency, moulting pattern and foraging areas of the 4 Pacific albatrosses of the genus Phoebastria illustrate well the moultbreeding trade-offs in relation to marine productivity. Like their southern counterparts, waved and short-tailed albatrosses (P. irrorata and P. albatrus, respectively), which are annual breeders, forage over neritic waters during their short moulting period (Gales 1993, Suryan et al 2007, ACAP 2011). By contrast, the Laysan and black-footed albatrosses (P. immuta bilis and P. nigripes, respectively) favou red more oceanic waters at that time (Gales 1993, Fisher et al 2009, ACAP 2011, and they consequently show unusual moulting and breeding patterns by alternating large (long) and small (short) primary moults that determine their breeding fre quency, with individuals showing both annual and biennial breeding patterns (Edwards 2008).…”

Investigating the foraging ecology of seabirds is especially challenging given their wide-ranging movements and the practical difficulties of obtaining unbiased information on their feeding behavior. Despite the development of animal-borne tracking devices, several limitations preclude investigations at the scale of a whole community in a given season or year, and, until recently, during the non-breeding period. Here we analyzed δ 13 C and δ 15 N in feathers of chicks and adults to investigate inter-and intra-specific variation in the foraging habitat and trophic position of 9 large procellariiform seabirds from 6 southern breeding localities during the breeding and non-breeding periods. Isotopic ratios of each species were generally consistent among different breeding populations, despite the large geographical scale and potential variation in oceanography in surrounding waters. Both spatial and trophic segregation apparently allowed the coexistence of sympatric species in most breeding localities, except at South Georgia, where both δ 13 C and δ 15 N in chicks showed high overlap among species, probably resulting from the superabundance of alternative food resources during the summer. Low variance in stable isotope ratios among adults in several species indicated high overlap between individuals in feeding habits and trophic levels (i.e. isotopic specialist populations) during the non-breeding period. By contrast, large isotopic variances and the high within-and between-individual components of the trophic niche width suggested that grey-headed and light-mantled sooty albatrosses are generalists. Based on δ 13 C, the species that breed in the Southern Ocean can be categorized as residents or subtropical migrants, with the latter including oceanic and neritic subtropical migrants. Albatrosses meet the high energetic challenge of feather synthesis by foraging in different habitats, depending on the length of the non-breeding period. Annual breeders renew their plumage in productive neritic waters in ~4 mo, whereas biennially breeding species moult in less productive oceanic waters over much longer periods (~12 to 16 mo).

“…For example, Suryan et al (2007) documented the use of 6 EEZs by short-tailed albatrosses Phoebastria albatrus along the rim of the north Pacific and assessed by-catch risk in each. The Caribbean Sea, Gulf of Mexico, and waters adjacent to the southern Gulf Stream, as well as international waters, contain ca.…”

The black-capped petrel Pterodroma hasitata is an endangered seabird with fewer than 2000 breeding pairs restricted to a few breeding sites in Haiti and the Dominican Republic. To date, use areas at sea have been determined entirely from vessel-based surveys and opportunistic sightings and, as such, spatial and temporal gaps in our understanding of the species' marine range are likely. To enhance our understanding of marine use areas, we deployed satellite tags on 3 black-capped petrels breeding on Hispaniola, representing the first tracking study for this species and one of the first published tracking studies for any breeding seabird in the Caribbean. During chick rearing, petrels primarily used marine habitats in the southern Caribbean Sea (ca. 18.0° to 11.5°N, 70.0° to 75.5°W) between the breeding site and the coasts of Venezuela and Colombia. Maximum distance from the breeding sites ranged from ca. 500 to 1500 km during the chick-rearing period. During the post-breeding period, each bird dispersed north and used waters west of the Gulf Stream offshore of the mid-and southern Atlantic coasts of the USA as well as Gulf Stream waters and deeper pelagic waters east of the Gulf Stream. Maximum distance from the breeding sites ranged from ca. 2000 to 2200 km among birds during the nonbreeding period. Petrels used waters located within 14 different exclusive economic zones, suggesting that international collaboration will benefit the development of management strategies for this species.
