Abstract

Quantifying abundance of wildlife is key for sound management and conservation. Much effort has been invested into freshwater dolphin surveys in the Amazon basin. However, river dimensions and complex logistics limit replication of such studies across the region. We evaluated the effectiveness of using Unmanned Aerial Vehicles (UAVs) for surveying two Amazon dolphin species, tucuxi (Sotalia fluviatilis Gervais & Deville, 1853) and pink river dolphin (Inia geoffrensis de Blainville, 1835), in tropical rivers. Compared to estimates derived from visual surveys, the use of UAVs could provide a less expensive and more accurate estimate of Amazon River dolphins. The aerial survey provided higher accuracy in counting individuals during the detection of groups.
