“…The guillemot breeds colonially on sea cliffs and normally members of a pair alternate incubation shifts of the single egg (the invariate clutch) or guard shifts of the chick, to provide continuous protection from predators and adverse weather (details of biology in Ainley et al 2002). Guillemots are singleprey loaders and thus a successful foraging trip results in the delivery of 1 fish to the chick.…”

“…Both species of Murres and Atlantic Puffins, similarly to Razorbills, eat schooling pelagic fishes including sand lance (Gaston and Hipfner, 2000;Ainley et al, 2002;Lowther et al, 2002;Bond and Diamond, 2006), and, though we lack dietary data from these species in our study area, it seems reasonable that part of their recent increases reflects increasing sandlance abundance. Black Guillemots also eat fish, including sand lance, but they feed in much more inshore waters than any of the other five species and therefore also take a variety of benthic species (Butler and Buckley, 2002).…”

Climate and changing winter distribution of alcids in the Northwest Atlantic

Population level impacts upon seabirds from changing climate are increasingly evident, and include effects on phenology, migration, dispersal, annual survivorship, and reproduction. Most population data on seabirds derive from nesting colonies; documented climate impacts on winter ecology are scarce. We studied interannual variability in winter abundance of six species of alcids (Charadriiformes, Alcidae) from a 58-year time series of data collected in Massachusetts 1954-2011. We used counts of birds taken during fall and winter from coastal vantage points. Counts were made by amateur birders, but coverage was consistent in timing and location. We found significant association between winter abundance of all six species of alcids and climate, indexed by North Atlantic Oscillation (NAO), at two temporal scales: (1) significant linear trends at the 58-year scale of the time series; and (2) shorter term fluctuations corresponding to the 5-8 year periodicity of NAO. Thus, variation in winter abundance of all six species of alcids was significantly related to the combined short-term and longer-term components of variation in NAO. Two low-Arctic species (Atlantic Puffin and Black Guillemot) peaked during NAO positive years, while two high Arctic species (Dovekie and Thick-billed Murre) peaked during NAO negative years. For Common Murres and Razorbills, southward shifts in winter distribution have been accompanied by southward expansion of breeding range, and increase within the core of the range. The proximate mechanism governing these changes is unclear, but, as for most other species of seabirds whose distributions have changed with climate, seems likely to be through their prey.

“…The population has a bimodal distribution, with breeding centers in northern California through northern Oregon (24%) and in Alaska (~70%; Ainley et al 2002). The post-breeding distribution is poorly known, although a general movement to inshore waters within the CCS, including Monterey Bay and the Strait of Juan de Fuca, has been noted (Briggs et al 1987).…”

Seabirds have often been proposed as environmental indicators. Beached bird data may provide an additional data source and such data is efficacious because it can reliably be collected by volunteers. In addition to anthropogenic factors, such as oil spills, changes in the ocean-atmosphere can affect carcass beaching rate in 3 non-exclusive ways: (1) direct mortality following storms, (2) mortality via bottom-up food web processes, and (3) increase in carcass delivery due to shifts in surface water movement. We used data from 3 volunteer-based beached bird data sets collected within the California Current System (CCS) to (1) examine the level of response to anomalous ocean conditions in 2005 and (2) explore the degree to which long-term beaching patterns could be explained by one or more of our proposed mechanisms. In 2005, anomalous die-offs of Cassin's auklet Ptychorhamphus aleuticus and the rhinoceros auklet Cerorhinca monocerata occurred in the winter in Monterey. By spring, anomalous die-offs of Brandt's cormorant Phalacrocorax pencillatus and the common murre Uria aalge occurred throughout the CCS. Over the longer term, increases in beaching were associated with changes in the timing and intensity of upwelling and, secondarily, with zonal winds aloft -a potential proxy of shifts in pelagic community composition. These results suggest that a bottom-up food web mechanism best explains seabird beaching, at least in the spring. Correlations of local measures of storminess to seabird beaching rates were weak to non-existent. Correlations were much stronger at the California site (8 yr) and weaker to non-existent at the Oregon site (26 yr). Collectively, these data suggest that relationships between ocean physics and beached bird response may be site specific and/or may reflect choices live birds make vis-à-vis non-breeding distribution.
