Project: Mapping & Quantifying Tern Nests in Senegal

Overview

The West African coast is a very important breeding and feeding area for large numbers of colonial breeding seabirds. It is crucial to know the numbers and distribution and reproduction success of these birds to be able to provide adequate protection. It is, however, difficult to obtain accurate counts without disturbing the colony. The purpose of this project was to develop methodology and test the use of drone photography for estimating colony sizes of colony breeding birds in general and Royal terns (Thalasseus maximus) specifically. The project took place in collaboration with BirdLife on Ansoukala island in the Saloum delta in Senegal.
