Interrelationships within a raptor guild in the central Canadian Arctic

Canadian Journal of Zoology, 1988
The interrelationships of an arctic raptor guild comprising golden eagles (Aquila chrysaetos), gyrfalcons (Falco rusticolus), peregrine falcons (Falco peregrinus), rough-legged hawks (Buteo lagopus), and common ravens (Corvus corax) (a functional raptor) were studied from 1983 to 1986.

Bayesian stable isotope mixing models effectively characterize the diet of an Arctic raptor

Journal of Animal Ecology, 2020
Abstract Bayesian stable isotope mixing models (BSIMMs) for δ13C and δ15N can be a useful tool to reconstruct diets, characterize trophic relationships, and assess spatiotemporal variation in food webs. However, use of this approach typically requires a priori knowledge on the level of enrichment occurring between the diet and tissue of the consumer ...

Linking pre-laying energy allocation and timing of breeding in a migratory arctic raptor

Oecologia, 2017
For migratory species, acquisition and allocation of energy after arrival on the breeding grounds largely determine reproductive decisions. Few studies have investigated underlying physiological mechanisms driving variation in breeding phenology so far.

Causes of differential migration distance: test of seven mechanistic hypotheses in an arctic raptor

Behavioral Ecology
Abstract Exploring the causes of differential migration, or variation in migration distance, has increased our understanding of the remarkable variation in migratory behavior exhibited by birds more generally. However, considerable uncertainty exists regarding the mechanisms underlying differential migration distance in birds despite it ...
