While we may hesitate a moment in believing the strict identity of this now-extinct bird with the hero character in one of the creation tales, it nevertheless seems […]

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 […]

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 […]

Distribution of Murres outside the Breeding Season

Thick-billed Murre (Uria lomvia) Science Article 1 abstract The main purpose of this document is to propose a coordinated international banding plan for Thick-billed Murres and Common Murres. Banding is an essential tool for describing with mapping the winter distribution of different murre populations, identifying overlapping distributions, determining the timing of migration, and ascertaining impacts […]

Sexing Razorbills Alca torda breeding at Machias Seal Island, New Brunswick, Canada, using discriminant function analysis.

Razorbill (Alca torda) Science Article 5 abstract In 2000 and 2001, we determined the sex of 80 adult Razorbills Alca torda caught on Machias Seal Island, New Brunswick, Canada, 71 birds in 2000 and 9 in 2001. Sex was determined for the 2000 birds using DNA from feathers, and for the 2001 captures using behavioural […]
