Atlantic Puffin (Fratercula arctica) Science Article 2 abstract Abstract.–Ages of Atlantic Puffin (Fratercula arctica) chicks are sometimes estimated by com-paring their wing lengths with a sample of known-aged chicks from the same colony. Thetechnique is reliable if the rate of wing growth is unaffected by variation in nutrition. Recentstudies suggest that wing growth may respond […]

Pretty patterns but a simple strategy: predator-prey interactions between juvenile herring andAtlantic puffins observed with multibeam sonar
Atlantic Puffin (Fratercula arctica) Science Article 4 abstract Predator-prey interactions between Atlantic puffins (Fratercula arctica) and newly metamorphosed herring(Clupea harengus) were studied in the Lofoten-Rost area in northern Norway using a high-resolution multibeam sonarsystem. Attacks from diving puffins and predatory fish induced massive predator-response patterns at the school level,including bend, vacuole, hourglass, pseudopodium, herd, and […]
Kinematics of diving Atlantic puffins (Fratercula arctica L.): evidence for an active upstroke
Atlantic Puffin (Fratercula arctica) Science Article 3 abstract To examine the propulsion mechanism of diving Atlantic puffins (Fratercula arctica), their three-dimensional kinematics was investigated by digital analysis of sequential video images of dorsal and lateral views. During the dives of this wing-propelled bird, the wings are partly folded, with the handwings directed backwards. The wings […]
Atlantic Puffin (Fratercula arctica) chick diet andreproductive performance at colonies with highand low capelin (Mallotus villosus) abundance
Atlantic Puffin (Fratercula arctica) Science Article 1 abstract We compared nestling diet and growth, breeding phenology, breeding success, and adult mass of AtlanticPuffins (Fratercula arctica) between two seabird colonies adjacent to ocean habitat with presumed high and low capelin(Mallotus villosus) abundance in 1996-1998. We hypothesized that puffins at their colony at Gannet Islands,Labrador, where capelin […]
