Table of tracking data; Plots of NND sex differences; Breeder tracking data; Immature tracking data; Failed breeder tracking data from Effects of age and reproductive status on individual foraging site fidelity in a long-lived marine predator

Table 1. Tracking data including in final analysis. Including here, the coefficient of relative plasticity (CRP), calculated for each individual as the ratio of the individual variance over the overall variance for each group. 0 = highly repeatable, 1 = low repeatability.; Figure 1. Plots of NND (mean±SE) for gannets tracked during multiple trips. (a) Within-individual route similarity for each group, by sex and (b) among-individuals only, for each group, by sex. Different females followed less similar routes than different males, in both breeders and immatures, and females also showing less route fidelity than males (at least in immatures, although less clear in adults).; Figure 2. Repeat foraging tracks of (n=46) chick-rearing northern gannets from Grassholm, UK July/August 2010, 2015 and 2016 generated from GPS loggers on a 2 minute duty cycle. Tracks are colour-coded by number: track 1=black; track 2=blue; track 3=red; track 4 = green; track 5 = purple; track 6=yellow. Data is presented for 15 females and 31 males.; Figure 3. Repeat central place foraging tracks of (n=15) immature northern gannets (aged 2-3 years) from Grassholm, UK, July and August 2010, 2015 and 2016 generated from GPS-PTT and GPS-GSM tags. Tracks are colour-coded by number: track 1=black; track 2=blue; track 3=red; track 4 = green; track 5 = purple. Data is presented for 8 males and 7 females. ; Repeat central place foraging tracks of (n=5) failed or sabbatical breeding northern gannets from Grassholm, UK, July 2015. Tracks are colour-coded by number: track 1=black; track 2=blue; track 3=red; track 4 = green.
