Table 2. Model selection assessing the influence of an Ovenbird’s origin on wing loading and homing time of translocated individuals.

Model QAICc Δi wi
Wing loading
Log(body mass [g]) + Julian date + time of day (h) 8.4 0.0 0.75
Log(body mass [g]) + Julian date + time of day (h) + origin (boreal or not) 10.5 2.1 0.25
Homing time
log(distance [m]) + forest cover (%) 913.1 0.0 0.83
log(distance [m]) + forest cover + origin (boreal or not) + forest cover × origin 916.3 3.2 0.17

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.
