Note: Ovenbird individuals were translocated in the boreal mixedwood forest of north-central Alberta ( n = 55; 19 right-censored cases) and in the temperate, northern hardwood forest of southern Québec ( n = 89; 20 right-censored cases). Log-transfomred wing loading was modeled using generalized linear models, and homing time was modeled using Cox proportional hazards regression models. Right-censored cases consisted of birds that did not return to their territory by 168 h post-translocation. The wi represents the weight of evidence in favor of model i as the best model in the set, given the data.
