Guillemot (Uria aalge) Science Article 3
The main purpose of this document is to propose a coordinated international banding plan for Thick-billed Murres and Common Murres. Banding is an essential tool for describing with mapping the winter distribution of different murre populations, identifying overlapping distributions, determining the timing of migration, and ascertaining impacts of various mortality factors, such as hunting, upon these.
