Its only rarely you get the opportunity to view the legs and feet of gulls and wildfowl. This recent cold snap has done the trick by hosting those usually submerged 'pins' from the icy depths to a position where they can be checked for Ratner style jewellery. At Bryn Bach Park yesterday there were several hundred assorted gulls along with a smaller number of coot, mallard and mute swan all standing on the frozen lake. The two ringed mute swan blogged on 5 December were joined by three other ringed birds of consecutive numbers. Now present are numbers ZY4632-33-34-35-36. Also noted was the above coot with ring number GC60061.
For gulls more than wildfowl ringers will certainly get more 'bang for their buck' if they use Darvic or colour rings in conjunction with the standard metal rings. With optical advances these days reading and photographing birds with rings is easier than ever but often still requires the bird to be viewed from several angles to read a full number. Ringers would get back more data if colours and larger numbers were available to view in the field, after all plotting the movements of birds is what ringing is all about and anything that enhances this must be worth it. By example the two ringed herring gull at Dunlop Semtex Pond recently were too distance to read a small number on a discoloured metal ring but with a colour ring things may have been different.
