In coordination with Bangor University and the British Trust for Ornithology (BTO), a colour-ringing project has been set up on Oystercatchers in the Lavan Sands area. The aim of the project is to observe longevity, site-faithfulness, juvenile feeding dispersal e.g. fields rather than sands etc as well as a mark and recapture technique of counting the how many birds are in an estimated flock size. Several counts like these will be sufficient to estimate the population size of the important wintering population of this impressive pied-wader.
The rings are as shown above: Green ring with a white engraving and an orange ring above.
If you are to come across any birds, whether it be a full ring code, partial ring code, or just a count of ringed birds in an estimated flock, please email: oystercatchers 'at' fidhw.com

I've written a little article on our website called Bird Spotting Locations in North Wales. It would be great if more knowledgeable people, like yourself or your readers on here, could comment and perhaps add more locations in the Guest Book bit at the bottom. Thanks in advance.
