Bird Ringing Codes. Recoveries of birds in the list where ring number and details are not included are published in atlases by those schemes. The Bird Banding Laboratory BBL is an integrated scientific program established in 1920 supporting the collection archiving management and dissemination of information from banded and marked birds in North America.
Bird ringing generates information on the survival productivity and movements of birds helping us to understand why populations are changing. This helps in keeping track of the movements of the bird and its life history. 45 35 32 10 29.

The new code builds on EURINGs previous work in the area providing conventions that are closer to the current working practices of most ringing schemes while minimising the need for disruptive changes.

When Ospreys are ringed they are usually fitted with two rings a metal BTO ring which has a unique number and an address so that finders can send finding details to the BTO as part of the national bird ringing scheme and a plastic ring known as a Darvic ring which can be viewed from a distance with binoculars or a scope. They allow quicker data entry than filling out the full English or scientific name of a species and they can also serve to cross-check other recorded names or numeric data.
