“…In previous studies, loggers up to 27g had no discernible impacts on foraging, breeding site attendance or food delivery to chicks of either species (e.g. Monaghan et al, 1994;Benvenuti et al, 2001;Tremblay et al, 2003), although some adverse effects have been detected using other devices (Hamel et al, 2004;Paredes et al, 2005). In this study, time spent at the colony during daylight hours did not differ between individuals with loggers and unequipped controls either for guillemots (11.1±2.7h and 10.7±3.9h, respectively; GLM with year as a fixed effect and bird identity as a random effect; F 1,40 0.1, P0.8) or for razorbills (10.0±3.7h and 10.7±2.5h, respectively; F 1,16 0.4, P0.6).…”

SUMMARYSpecies of bird that use their wings for underwater propulsion are thought to face evolutionary trade-offs between flight and diving, leading to the prediction that species with different wing areas relative to body mass (i.e. different wing loadings) also differ in the relative importance of flight and diving activity during foraging trips. We tested this hypothesis for two similarly sized species of Alcidae (common guillemots and razorbills) by using bird-borne devices to examine three-dimensional foraging behaviour at a single colony. Guillemots have 30% higher wing loading than razorbills and, in keeping with this difference, razorbills spent twice as long in flight as a proportion of trip duration whereas guillemots spent twice as long in diving activity. Razorbills made a large number of short, relatively shallow dives and spent little time in the bottom phase of the dive whereas guillemots made fewer dives but frequently attained depths suggesting that they were near the seabed (ca. 35-70m). The bottom phase of dives by guillemots was relatively long, indicating that they spent considerable time searching for and pursuing prey. Guillemots also spent a greater proportion of each dive bout underwater and had faster rates of descent, indicating that they were more adept at maximising time for pursuit and capture of prey. These differences in foraging behaviour may partly reflect guillemots feeding their chicks single large prey obtained near the bottom and razorbills feeding their chicks multiple prey from the water column. Nonetheless, our data support the notion that interspecific differences in wing loadings of auks reflect an evolutionary trade-off between aerial and underwater locomotion.

“…Because resighting effort was very thorough at all five puffin breeding colonies in the Gulf of Maine (the three study islands as well as the nearby puffin colonies at Machias Seal Island, New Brunswick, and Petit Manan National Wildlife Refuge, Maine), we believe that we resighted most of the returning puffins. We use the return rate of banded birds as a metric that approximates survival, an approach that is common in avian studies (Hamel et al 2004;Oro et al 2011). To allow for maturation at sea by some individuals, we did not include chicks weighed and To determine if there was a difference in postfledging survival in relation to the chick condition, we used a T-test comparing the weight/wing cord ratio of 612 chicks that were later resighted at any breeding colony in the Gulf of Maine and 276 chicks that were not resighted.…”

We examined the diet of Atlantic puffin (Fratercula arctica) chicks at three midcoast Maine, USA, colonies during the years 2005-2014 and found that the puffins at each island have a distinct diet that has changed in recent years. White hake (Urophycis tenuis) is by far the most frequently delivered prey at each island. Atlantic herring (Clupea harengus) is the second most frequently delivered food, but has declined in recent years on two islands. In contrast, butterfish (Poronotus triacanthus), haddock (Melanogrammus aeglefinus), and redfish (Sebastes spp.) have increased in the puffin diet on all islands. Chick condition declined significantly from 1993 to 2009. We demonstrate that puffin chicks with greater body weight experience a higher chance of postfledging survival as compared to chicks with lower body weight. The years 2012-2013 were a period of extreme sea surface warming, in which puffin hatching success and productivity sharply declined. This study provides new insight into changes in marine communities, examining changes in chick diet. We discuss our findings in relation to warming sea surface temperatures, recent climate-related decline in puffin productivity in the Gulf of Maine, and the impact of commercial fisheries on forage fish.

The effects of loggers on the foraging effort and chick-rearing ability of parent little auks

et al. 2011

We studied the effects of loggers attached to chick-rearing little auks (Alle alle) on their daily time budget (proportion of time spent in the colony and at sea), foraging activity (duration and proportion of long and short foraging flights), chick provisioning rate and their growth and development on Spitsbergen. We found that experimental parent birds performed shorter but more frequent long foraging flights and reduced the frequency of short foraging flights. They spent more time at the colony and reduced chick provisioning rate compared to control birds. Nestlings reared by experimental parents weighed significantly less at their middle, peak and fledging age and departed colony later than chicks of control parents. Little auks depend on energy-rich copepods associated with cold Arctic waters and are expected to face the climate-induced worsening of the foraging conditions, which may have negative impact on their time/energy budget and survival. The study may help to determine the level of extra effort little auks need to invest to breed successfully.
