Since October of 2013 all seagulls recovered in CRAM-Q are released with a blue colour ring, making it possible to followed them by sighting, without the need of recapture.
Three years after, we reach the goal of the ring 100.
Of these 100 birds released with colour ring, we collect information from 132 sightings for 41 birds, nine of them in foreign countries such as England, Holland and Morocco.
A good indicator of the success of recovery of these birds.
