Bird ringing in Britain and Ireland in 2007.

The article reports on the European bird ringing schemes organization EURING which partnered with a web-based application to develop the mapping migration routes of waterfowl species which are identified with the highest potential to carry Highly Pathogenic Avian Influenza H5N1 across Europe. It states that the Constant Effort Site (CES) ringing demonstrated how the heavy rainfall during summer of 2007 had a negative effect on the breeding success and present recoveries of birds and their migration patterns and longevity records. It suggests that the total number of birds ringed was 7% lower than the mean of previous years due to the heavy rainfall that affects their breeding success.
