Elephant listening project and WWF CAR are working on elephant identification in Dzanga Baï (clearance in the forest) since several years now. We would like to compare our genealogy trees based on individual identification with DNA sampling, and understand forest elephant social and mating system.
The problem is that we would need DNA sampling of the specific individual observed in the baï after a defecation. But there is something 150+ elephant at the same time, and we can't disturb them. The terrain of the Baï is wet with water flows, mud, holes, grass, so something flying seems to be more adapted. But elephant are scared of conventional drones (such as DJI) so it will need to be smaller and silent or maybe display a bird call find in the baï (duck?).
So any ideas how we could sample in the context? Anyone use a drone that could also work here, or know an engineer team that would be interested?
