Description

This report describes the method, output and learning from a trial of a high-definition video survey technique for census of seabirds and windfarm sites. The technique utilises a gyroscopically stabilised camera mount to eliminate aircraft vibration enabling the use of high magnification lenses. This in turn enables the helicopter to fly at a significant distance from the birds, while still maintaining sufficient image quality to identify them and assess certain aspects of their behaviour. The video is coupled with a GPS logging system that associates a geographical location with each video frame, enabling subsequent statistical analysis of the spatial distribution of birds.
