@LilianLieber @BrydenCentre_EU @AlexNimmoSmith @PlymUni @RolandLangrock @unibielefeld #WSTC8 #ForSesh - Brilliant, Lilian! Super neat. Do you know if there is empirical evidence of surface slicks influencing marine top predators other than seabirds? (Ooops, a slight topic detour...😅)

What a fantastic work at #WSTC8 #ForSesh by @LilianLieber The use of #drones for studying #seabird fine-scale foraging behaviour in surface slicks

1/4 #WSTC8 #ForSesh #ForagingEcology Seabird foraging is often driven by dynamic #physical processes enhancing prey accessibility. Surface #slicks are ubiquitous coastal #ocean features where convergent flows accumulate flotsam, concentrating marine organisms & plastics. #SciComm

4/4 #WSTC8 #ForSesh This research can also help us to assess how seabirds interact with slicks in areas exposed to pollutants (oil spills & plastics). Do terns select slicks for foraging? Watch this space! @BrydenCentre_EU @AlexNimmoSmith @PlymUni @RolandLangrock @unibielefeld

3/4 #WSTC8 #ForSesh Here, we use aerial #drone surveys to investigate such fine-scale interactions. We track foraging terns in the presence of meandering slick lines & visualise and extract dynamic slick signatures using computer vision techniques. @DJIGlobal #remotesensing #UAV

2/4 #WSTC8 #ForSesh Slicks can manifest on the sea surface as meandering lines and seabirds often associate with slicks. However, how slicks influence the fine-scale foraging behaviour of #seabirds is only coarsely resolved.🔊= audio recording of a #tern plunge-diving.

3) #WSTC8 #ForSesh All trips were short (-24hours), mostly placed within 11km from the colony. Cumulative distance, trip duration, number of dives and bottom duration decreased throughout the season(Dec-Feb), followed by a quadratic trend in mean and maximum depth.🐧🦐🇦🇶

1) #WSTC8 #ForSesh Breeding #seabirds need to adjust their #foraging behaviour according to their chicks’ requirements. In the #AntarcticPeninsula, #penguins time their reproduction so the chick-rearing coincides with the period of higher resource availability🐧🦐🇦🇶

8-9 #WSTC8 #ForSesh Additionally, we found that #TrophicLevel of Magellanic penguins estimated based on δ15N values increased with latitude, which matches to the size-distribution of both #ForageFish prey species, indicating the size-age of prey they feed on
