Table 3 Environmental predictor variables retained in the best models explaining the distribution of foraging bouts in black-browed albatrosses (BBA) and grey-headed albatrosses (GHA) during different breeding stages

From: Effects of age on foraging behavior in two closely related albatross species

 BBA Incubation  x     0.76 ± 0.11
 BBA Brood-guardx x, SST: Sex     0.89 ± 0.08
 GHA Incubation  x, SST: Sex: Age     0.76 ± 0.12
 GHA Brood-guard  x, SST: Sex: Age     0.81 ± 0.08
  1. Habitat preference models were constructed separately for both species and for the incubation and brood-guard breeding stages. An ‘x’ indicates terms retained in the best model for each combination of species and breeding stage. Where an ‘x’ is followed by a colon and either ‘Sex’, ‘Age’ or ‘Sex: Age’ indicates a two or three-way interaction of those terms with that particular environmental predictor variable. Mean Area Under the Curve (AUC) scores and standard deviations (sd) of those scores for each model are indicated in the final column. Values of 0.5–0.7, 0.7–0.9 and > 0.9 represent poor, reasonable and very good model performance, respectively
