ABSTRACT
Presents a study that investigated the density-dependent effects on body condition and stopover patterns of northern saw-whet owls in relation to the irruptive nature of their migration. Primary cause of bird migration; Assessment of the body masses of the owls during migration years; Application of logistic regression to test the relationship between the probability of recapture and the body condition of the owls.

    The extent of post-juvenile moult in passerines is highly variable, but the causes and consequences of such variability remain poorly understood. We tested the hypothesis that the extent and symmetry of post-juvenile moult of Greenfinches Carduelis chloris may be used as reliable predictors of...
