Table 2 Summary table of the best models (Julian day only (A), Julian day + sex (B), Julian day + breeding status (C) and Julian day + study area (D)) for daily distance travelled (km), mean daily speed (km/h), and proportion of active time (%). Values represent estimated parameters ± standard error (factor variables) or estimated degree of freedom (numeric variables). Reference category = female for sex, breeding for breeding status and Hochstetter for study area; S(Julian day) = spline of Julian day
