The IWSG Colour-mark Register
The IWSG Colour-mark Register is the definitive database of all schemes for waders in the East Atlantic flyway. All ringers conducting colour-marking studies throughout this flyway first register their schemes with the Register to ensure no overlap with existing schemes. The Register is also a means to discover the origins of a marked bird you may have seen.
