“…4A), which does support the 'stay on prey patch' hypothesis. Ostrand et al (1998) also found a positive relationship between marbled murrelet and prey distribution in Prince William Sound, Alaska, where birds selected small, dense fish schools in shallow waters that were associated with stratified water. The oceanography of Prince William Sound has fewer potential prey-aggregating mechanisms than the highly dynamic California Current, and may be similar to California waters when upwelling is low or relaxed.…”

“…Only the tufted puffin, however, exhibited near complete breeding failure in the warmest years, suggesting a sensitivity that surpassed that of the other species. Puffins tend to be diurnal foragers that provision young multiple times per day, a strategy that restricts parental foraging range (Ostrand et al 1998). In contrast, each rhinoceros auklet parent provisions its young at most once per night (max.…”

This paper presents time-series information on the diet composition and breeding performance of rhinoceros auklet Cerorhinca monocerata at Triangle Island, British Columbia, Canada, during 15 breeding seasons between 1976 and 2001. Three shifts in ocean climate occurred within British Columbia during this period (1976-77, 1989-90, 1998-99), allowing us to evaluate associations between marine environmental conditions and the reproduction of this piscivorous seabird. Lipid-rich Pacific sand lance Ammodytes hexapterus was the single most important prey delivered to chicks across years (15 yr avg. 38%; annual range 4 to 86%). Interannual variability was high, but in general breeding performance was strongest when 0+ sand lance predominated chick diets. Other annually important prey taxa included Pacific saury Cololabis saira, juvenile rockfishes Sebastes spp., Pacific herring Clupea pallasi and juvenile salmonid Oncorhynchus spp. The dietary importance of these prey also varied seasonally. Marine environmental conditions (evaluated using sea surface temperatures, SSTs) were clearly associated with reproduction of rhinoceros auklet, as both occurrence of sand lance in the diet and the growth rates of chicks diminished as spring SSTs increased (r = -0.680, p < 0.01, and r = -0.697, p < 0.01, respectively). We hypothesized that recruitment to local sand lance populations was temperature dependent. The strong negative relationship between dietary occurrence of 0+ sand lance and spring SST (r = -0.560, p < 0.05), coupled with the lack of a similar relationship for 1+ sand lance (p > 0.20), was consistent with the temperature-dependent recruitment hypothesis. Our data suggest that SSTs could interact with population age structure to affect the recruitment dynamics of Pacific sand lance. We estimated the annual dietary importance of 0+ sand lance to rhinoceros auklets using spring SST and the importance of 0+ sand lance in the diet the previous year.

“…The physiological requirements for survival, or time to starvation (Horne & Schneider 1994), is likely the most important determinant of the tracking scale of seabirds due to their high metabolic rates and low energy reserves compared to other marine animals (Gabrielsen 1994, Gaston & Jones 1998. Physical characteristics of the foraging environment of seabirds, such as hydrographic regimes, combined with prey behaviour, influence the spatial scale and density of prey patchiness (Mehlum et al 1996, Ostrand et al 1998) and the stability of prey patches in space and time (Cairns & Schneider 1990, Hunt & Harrison 1990, Irons 1998. These factors in turn affect predator tracking scales (Rose & Leggett 1990, Davoren 2000.…”

We examined the behavioural interactions of a mobile marine predator, the common murre Uria aalge, and its prey in a cold ocean regime in the context of shifting foraging constraints of the predator during various periods of the year. To do this, we explored the scale-dependent distribution patterns of murres in relation to their prey under 2 mobility regimes: (1) during the pre-breeding period when murres can fly and (2) during the post-breeding or moulting period when murres are flightless and are accompanied by flightless juveniles. In addition, we documented for the first time the relative contributions of different prey types in the diets of murres during moult using stable isotopic analysis. Flightless adult and juvenile murres were concentrated on a meso-scale (>100 km) in an area (nursery area) where significantly greater amounts of non-capelin, mainly crustaceans, were located in closely spaced aggregations. Accordingly, flightless murres had variable proportions of fish (capelin Mallotus villosus) and crustaceans in their diet, whereas breeding murres exclusively ate capelin. At fine-and coarse-scales (0.1 to 100 km), murres that could fly during pre-breeding tracked prey at smaller spatial scales (3 to 4 km) than flightless murres (6 to 9 km). We hypothesize that varying mobility regimes and energetic demands (activity levels) of murres during these 2 periods resulted in divergent perceptions of the foraging environment and subsequently in varying tracking scales of prey. This has important implications for the scale of study during different periods of the annual cycle of a predator, when varying constraints and trophic levels may interact to produce diverse behavioural responses to prey distribution and densities.
