To validate UAV photogrammetry methods for measuring body size and condition in bottlenose dolphins.
Compared UAV-derived measurements with manual measurements of body dimensions.
Assessed accuracy and precision using dolphins under human care.
Calculated volume-based and mass-based body condition indices.
UAV measurements showed negligible differences from manual measurements.
High precision and accuracy were confirmed, especially for swimming dolphins.
Volume-based body condition index matched traditional mass-based metrics closely.
