4/4 #WSTC8 #DigSesh1 We show that the combination of a cheap drone, together with the use of a free access program, allows for an accurate and efficient monitoring of island breeding seabirds, and that this method is three to five times faster compared to the manual alternative

3/4 #WSTC8 #DigSesh1 We obtained similar values of agreement between manual and semi-automated counts (99.1%), reducing the analysis time fivefold. In addition, we propose a correction factor to detect breeding birds in the colony, with a 103.5% accuracy

2/4 #WSTC8 #DigSesh1 Whereas there are different (semi-) automated counting processes that have been recently developed (i.e. #ARCGis, #MachLearn), they usually involve the use of expensive software. We show that similar results can be achieved using the free software #ImageJ

1/4 #WSTC8 #DigSesh1 Long-term monitoring of breeding seabirds is fundamental for assessing conservation status of the populations. While using drones as monitoring tools reduces human presence (and disturbance!) in the field, handling the obtained data can be time consuming

How do I get hold of this ‘Prof Mike Harris and I’ software ??? Fantastic effort processing all those camera trap images 👏🏻 #WSTC7 #DigSesh1

@EllieBowler32 Wow, yep - huge effort! But will hopefully save a lot of time in the future if results are consistent - I'll keep my eyes peeled for the paper. It will be great to see this method applied to more datasets in the future. Fantastic stuff! #WSTC7 #DigSesh1

@animal__alice @zooniverse @seabird_watch Thanks for a great presentation, @animal__alice! Why do you think the biggest difference was with chicks? Are they harder to see / difficult to tell apart from adults? And is there anyway to improve this? #WSTC7 #DigSesh1

What a wonderful session! Big thanks to our #DigSesh1 presenters @_jezbird @bennett_sophie @EllieBowler32 & @animal__alice. If you’re after more Digital Imaging #seabird research, make sure you catch the second session #DigSesh2 later today at 13:40 UTC! #WSTC7

Thanks @animal__alice. It’s great to see results coming from all the hard work of the citizen scientists (& you, of course)! Now is the time to ask your Qs #WSTC7 #DigSesh1 & if you fancy helping count seabirds… head to https://t.co/Ptiq6jkHC9 to join in!

@EllieBowler32 Great work @EllieBowler32. It's quite fascinating to know how we can integrate #UAV and #MachineLearning techniques for studying seabirds. #WSTC7 #DigSesh1

@_jezbird Lovely presentation, thanks Jez! Did you have any breeding attempts that failed - were you able to pick these up? And was it easy to tell apart advanced fledglings from adults? #WSTC7 #DigSesh1

4-4 #WSTC7 #DigSesh1 #Cameratrap deployment and analysis is time consuming and has challenges. For longer studies it could reduce uncertainty when estimating occupancy and br-success, but for short surveys it’s impractical.

3-4 #WSTC7 #DigSesh1 Phenology and breeding success can be determined direct from activity patterns. Metrics like time between activity peaks were used for Linear Discriminant Analysis. Promising results suggest discrimination between breeding + non-br burrows is possible.
