Citizen science at Sa Dragonera Island! Saturady 24 April.

Do you like wildlife photgraphy? Suscribe for the Red Ring Challenge here and join our long-term research on the Yellow-legged gull at Sa Dragonera Island.

Take a picture of a marked gull and win an original T-Shirt. 

Presence-absence data of marked animals are extremely important as they can be used to estimate annual survival probability and movements of individuals within the breeding colony. 

The project, funded by the Spanish Ministery of Science and Education, will investigate how the management of discards from human activities influences the ecology of gulls.
