Bird-borne cameras reveal seabird/fishery interactions.

<p>All tracked gannets photographed fishing vessels, often in the company of large groups of other scavengers.</p

Bird-borne cameras reveal intra- and inter-specific interactions, and fishing vessel type.

<p>93% of vessel encounters illustrated that northern gannets foraged with other birds, including conspecifics above (A) and below the water (B), as well as northern fulmars (<i>Fulmarus glacialis</i>) (C). Fishing vessels were visited during crepuscular foraging (D). The vast majority (95%) of fishing vessels encountered were trawlers, including stern trawlers (E) and beam trawlers (F).</p

Daily horizontal distances, daily number of prey catch attempts and daily body densities across the trips of 4 SESs.

<p>Colours indicate the predominant oceanographic domain visited during each day: (1) habitat 1 in green, (2) habitat 2 in blue and (3) habitat 3 in red. See supporting information for plots for all individuals (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0166747#pone.0166747.s002" target="_blank">S2 Fig</a>).</p

Distribution of the 3 oceanographic domains (habitat types) along each of the 10 trips performed by SESs: habitat #1 (green) is north of the sub-Antarctic front (yellow line), habitat #2 (blue) lies between the sub-Antarctic front and the polar front (cyan line) and habitat #3 (red) is south of the polar front.

<p>Frontal locations were defined using temperature and salinity measurements taken at 200m depth [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0166747#pone.0166747.ref026" target="_blank">26</a>–<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0166747#pone.0166747.ref028" target="_blank">28</a>].</p
