Terns & Gulls Part 2

Following on from Part 1, I have a few more photographs to show you.

Above: Our method of transport. I still got my feet wet by chasing after juveniles that had got into the water.

The one Common Tern that I ringed today. This year, the terns were colour ringed to identify individual birds. On the right leg, the BTO metal ring (that gives the bird a unique number) sits on the leg above the white (plastic) ring. On the left leg, the white ring sits above the black ring. It is possible to have many different ring combinations. Which leg the rings are on & their combination (e.g. white on top of black) helps BTO (British Trust for Ornithology who are informed about sightings) identify the group of birds which an individual came from or (in this case) a specific individual. This means that with binoculars/telescopes, people can identify a ringed bird & pass the information on without having to recapture the bird. A huge advantage.

Above: Again, me and the Common Tern with the rings on it. I am holding the bird in the 'ringers grip.' The Common Terns are smaller than the black headed gulls and they also have a white front.
