Description:

Two swans flew in on 14/12 with a couple of youngsters. I got the ring codes and sent them to our local recorder, he soon sent me the information back. FF6 ringed as an adult female New Springs, Wigan 10/12/2011. Probably on the canal.
SLI ringed as adult male on Heapy Lodges 4/9/2005. He also was on the canal last year, he also has a split in his top beak that makes him easy to spot in the water. VU6 our own resident female ringed this year with just one of her cygnets the rest avoided the catchers.

Rings

Hi. Very interesting info gathered from the rings. I must be getting old and grumpy but cant they remove the old ones from their left legs when they fit the new ones? I suppose that they gain other historical info from the old rings too.

Rings

They are not old and new rings, really. The BTO metal ring is the standard ring and will normally last the length of the bird's life. The colour rings are less durable and can become brittle and break off or can fade with time. They provide a good number of resightings, just as you have proved here, but they do not replace the metal ring, which also has the full finding requirement of an address for the ringing scheme.

Ringing

I am not a ringer but I can tell you the metal ring is still put on as it is the BTO one, the plastic or Darvic ring can be seen easily by the birders and people who like to take an interest and can then report them to their local group or the BTO, it is amazing how far some of these birds fly. I know some people do not agree with ringing for various reasons, I think the information gained can be useful.

Explanation

Thanks for the explanation for the different ring types and yes I can see that the plastic variety is not likely to be as durable and long lasting as the metal. Carry on the good work ringing.
