Obtaining data

EURING is keen to promote the maximum use of the data gathered by its member schemes and welcomes applications to analyse data held in the EURING databank (EDB). These data are suitable for addressing a range of questions concerned with migration and movements, population dynamics and dispersal. Examples of analyses of migration and movements can be found in the growing number of Migration Atlases. EURING has also been actively involved in promoting quantitative analyses of population dynamics and movements via the EURING technical conferences.

The data held in the EDB are principally recoveries of ringed birds that have either been found dead or recaptured alive away from their place of ringing. Some local recaptures are included but for many schemes this aspect of the data is very incomplete. (Schemes' practices for inclusion of data are described here.)

During 2011, the EDB began to accept data on ringed birds that have not been recovered or recaptured. At the same time, records which include biometric data, such as measurements, body mass and moult information, were accepted. These data represent only a small proportion of the EDB holdings at present, but will increase with time.

The data for most birds comprise two or more encounter records. The main fields provided for each encounter are ringing scheme, ring number, species, age, sex, date, place, co-ordinates and recovery circumstances (e.g. shot, captured by ringer).

Distance, direction and elapsed time relative to the original ringing record are also provided. Full details of the coding scheme are available here.

The application procedure is provided here.
