Bardsey is owned freehold by a charitable trust, but the main lease is held by the RSPB and the Island also has an active Bird Observatory. So, the study of birds is an important part of island life. To help with this there are many nets in which birds are trapped, bagged, identified, weighed, recorded and then ringed for future reference. From this information a picture can be established of trends in bird life, longevity, migration patterns, population growth and the like.
First the bird is identified and aged and checked for any previous ringing.
Then the bird is weighed
Meticulous records are kept
The birds are then released and seem none the worse for wear.
Are these birds edible?
