#WSTC8 #DigSesh #ToolSesh Big applause and many thanks to all the presenters for a super interesting combined session on Digital Imaging and Tools and Techniques in #seabird #research @AlexCoCastro @nattenstein @sweet_starling @CostagliolaRay @seabirdK

#WSTC8 #Toolsesh Again, further reading available for those interested! jstor.org/stable/1623?se… link.springer.com/article/10.100…

4/4 #WSTC8 #ToolSesh #Yearofterns Finalizing 2021 analysis &report; In 2022 address issues of colony accessibility (need helicopter) and estimate of detection probability before we scale up to a statewide effort in 2023. Please share any info you may have on tern colony locations

#WSTC8 #Toolsesh Apparently! I wasn't expecting it when we set out, we were looking for pellets mostly (on the ground), but saw so much more poop we decided to scoop it up and try to sift through it for identifiable bits. Worth it!😄

3/4 #WSTC8 #ToolSesh We surveyed 2,293 of 3,786 cells (61%) in Stratum 1 and covered almost 2700km of coastline; estimated density of 23 Aleutian Terns per 100km; 10 of 49 colonies had Aleutian Terns; estimated 1,485 ALTEs. Statewide estimate was ~5,000 ALTEs (Renner et al. 2015)

2/4 #WSTC8 #ToolSesh Goal: develop scalable colony (aerial) survey protocol. Objectives: estimating colony prevalence & tern abundance. Study design included Phase 1-with 2 Strata (coastal, 1 km inland; 1km x 1km grid) & Phase 2 ground counts at colonies located during Phase 1.

1/4 #WSTC8 #ToolSesh #Yearofterns The Aleutian Tern (ALTE) is one of Alaska's most imperiled seabirds owing to population declines of >80% at known colonies in recent decades. In 2021, we tested a colony survey and monitoring framework in southwest Alaska.

4/4 #WSTC8 #ToolSesh We also aim to uncover particular scanning protocols observers can adopt to ensure that counts of #seabirds are as accurate as possible. For example, changing the speed at which observers scan and the direction of scans (i.e. with or against the current).

Thank you so much @CostagliolaRay Are there any questions for Melissa? #WSTC8 #DigSesh #ToolSesh

3/4 #WSTC8 #ToolSesh This work will use individual-based modelling (IBM) to assess the influence of different dive times of #seabirds and different current speeds (high, medium, & low) on the accuracy of seabird counts made by observers undertaking traditional VP surveys.

2/4 #WSTC8 #ToolSesh These biases are exaggerated within high energy environments due to the dynamic nature of these areas. This is of particular relevance to tidal stream and wave energy generation. #ornithology #marinerenewables

1/4 #WSTC8 #ToolSesh Land-based vantage point (VP) surveys are a widely used method of collecting #seabird abundance and distribution data for environmental impact assessments. However, VP surveys are prone to biases due to detectability issues.

#WSTC8 #DigSesh The next presenter in #ToolSesh is Melissa Costagliola-Ray @CostagliolaRay From @ERI_UHI @BrydenCentre_EU Using individual-based modelling to investigate the potential biases of land-based vantage point surveys for assessing seabird abundance #Monitoring

Thank you very much Emma @sweet_starling for this great presentation! There is still time for questions Remember to add #WSTC8 #DigSesh #ToolSesh

#WSTC8 #ToolSesh no worries, good question!🦀such as velvet & edible (main prey found) are found at bottom of seafloor, which is also where most commercial tidal turbine structures are...incidentally saithe also known to aggregate at offshore structures so attraction relevant!

#WSTC8 #Toolsesh Nope! I've heard metabarcoding could have been an option (do you know more?) but we opted for cost & logistic effectiveness in this one😅

#WSTC8 #ToolSesh Next on #DigSesh we have Emma Caulfield @sweet_starling from University College Cork presenting “Semi-automated counts on drone imagery of breeding seabirds using free accessible software” #DigitalImaging #Conservation

#WSTC8 #ToolSesh, Sorry ab this question since it's not the objective of the presentation, but any idea why the overlap btw prey sp and turbine?...

#WSTC8 #Toolsesh Did you run DNA tests on the shags' poop?

2/4 #WSTC5 #ToolSesh Time-lapse photography is most applicable to study animals frequently present at a location or to study frequently repeated behaviors, SO it is particularly relevant to study colonial animals such as seabirds and seals, breeding in large groups.

3/4 #WSTC6 #ToolSesh We identified 23 🐟 species in the diets of Common Terns, with an average of 2.5 species per 💩. Adult and chick diets were largely similar. We also collected Roseate Tern 💩. They showed a preference for sand lance (sand eels) at this colony. #TeamTern

4/4 #WSTC6 #ToolSesh Comparing poop 💩 data to visual observations, we found similar proportions of the main prey. ➡️Faecal #metabarcoding would be a reliable method to track changes in diets over time. ➕We can identify more species and monitor adult diets for the 1st time.

1/4 #WSTC6 #ToolSesh CIAs exclude rapid #ClimateChange impacts thus lack spatial-temporal appropriate baselines linking ecosystem components to #Seabirds population dynamics #cumulative #impact #assessment #offshorewind @BEScott_abdn @TrifonovaNeda @JNCC_UK @beisgovuk @UoABioSci

I hope you're enjoying the #WSTC5 so far. Next up, we've got our 'Tools and Techniques' session, with 6 amazing presenters. Don't forget to include the conference and session (#ToolSesh) hashtags when asking questions & presenting. Here we go! 🐧🐧🐧 #Seabirds #Ornithology

3/4 #WSTC5 #ToolSesh 34% of chicks ready to fledge (colonies and rescued), showed a low #WettabilityIndex. For the birds tracked in 2018, only those with an index indicating a #WaterproofPlumage successfully dispersed, others stopped transmitting soon after landing on water.

3/4 This work aims to address the current limitations of VPS techniques (e.g. investigating factors known to influence observer detection). The real-world relevance of such questions increases as our use of these habitats increases #WSTC6 #ToolSesh #marinerenewables #aquaculture

2/4 A widely used technique for assessing seabird abundance and distribution within nearshore areas is vantage point surveys (VPS) from the shore. However, the ability of VPS to gather data can be compromised by several limitations. #WSTC6 #ToolSesh #ornithology #seabirds

1/4 #WSTC5 #ToolSesh Tech to collect data from birds in flight is often adapted, rather than developed, for, this use. Validation & performance testing before deployment can help inform the usefulness & limitations of such tools. One such tool is the ornithodolite (LRF) @ERI_UHI
