“…Seabird dietary studies can inform ecosystem risk assessments for fishery management by identifying interactions between fisheries and seabirds for different populations (Phillips et al, 1999a). Understanding the dietary flexibility of seabirds is also fundamental for predicting the responses of individuals and populations to spatial and temporal changes in natural prey abundance, and availability from fisheries, and hence for the effective management of marine resources (Constable et al, 2000).…”

“…Unfortunately, we did not sample known breeding birds very late into the breeding season at Cape Vera, but our data did not suggest a significant increase in fish consumption in August samples (0.3 to 0.4 fish bird -1 at Cape Vera, Cape Searle and the North Water Polynya). Phillips et al (1999), studying the diet of fulmars near Disko Island, Greenland, recorded a similar proportion of birds consuming fish (38%), but these were mostly capelin Mallotus villosus. Like our study, they did not observe an increase in fish consumption as the breeding season progressed (in fact, fulmars shifted to crustaceans and pteropods later in the breeding season).…”

“…We found polychaete remains in 41% of the fulmars at Cape Vera, but occurrence was lower in May than in the latter months of the breeding season. Presumably, this temporal pattern is attributable to the availability of the worms at the surface; Nereis are more common at the surface when spawning in the warmer summer waters (Phillips et al 1999). Arctic fulmars could be ingesting polychaetes directly, or could be getting their remains secondarily by consuming fish that had eaten polychaetes; our data do not allow us to distinguish between these possibilities.…”

“…Fisher (1952) famously proposed that the huge expansion in range and population size by northern fulmars since the 17 th century was linked to exploitation of offal and discards. While the validity of this hypothesis is difficult to test, more recent studies indicate that fulmar at-sea distribution is more closely linked to oceanographic features than to availability of discards (Camphuysen & Garthe 1997), and that while discards constitute an important fraction of fulmar diet in some areas, they are rarely the most important food item (Phillips et al 1999). It thus seems unlikely that the current range and population size of fulmars is limited by the availability of discards, and that current and future reductions in amounts of discards will have widespread negative effects on this species.…”
