TUFTED PUFFINS (FRATERCULA CIRRHATA) RESPOND TOPREDATION DANGER DURING COLONY APPROACH FLIGHTS

Tufted Puffin (Fratercula cirrhata) Science Article 2 abstract In spite of their putative importance in the evolution of certain traits (e.g., nocturnality, coloniality, cliff nesting), the effects of aerial predators on behaviorof adult seabirds at colonies have been poorly investigated. We hypothesized that Tufted Puffins (Fratercula cirrhata) respond to danger posed by aerial predators by […]

Ornaments and overflight behaviour of Tufted Puffins (Fraterculacirrhata) breeding on Triangle Island, British Columbia.

Tufted Puffin (Fratercula cirrhata) Science Article 3 abstract Tufted puffins (Fratercula cirrhata) are unusual among seabirds in that they bearmultiple colourful ornaments during the breeding season. They also engage in colony overflights when approaching the colony with food for their chicks. Blackburn, G., Simon Fraser University, Burnaby, BC. 74 pp Download article download full text […]

Nestling growth and parental provisioning of Tufted Puffins (Fratercula cirrhala) on Triangle Island, British Columbia

Tufted Puffin (Fratercula cirrhata) Science Article 1 abstract I studied the reproductive performance of tufted puffins (Fratercula cirrhata) on TriangleIsland, British Columbia during two years when reproduction was successful. Completereproductive failures are common for this population. I report on the timing of breeding, nestling growth, fledging behaviour, nestling diet, and parental provisioning, and discuss the […]

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 […]

Relationship between wing length and body mass in atlantic puffin chicks

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 […]

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 […]
