The EURING databank (EDB) holds a high proportion of the ringing recovery data that have been gathered by bird ringing schemes throughout Europe. The databank is hosted by the British Trust for Ornithology. The data are computerised according to standard protocols that are used by all EURING schemes. This index provides a summary of the information that is held in the EDB, including maps of the distributions of ringing and recovery locations.
EURING is very keen to promote more analyses of these data and welcomes applications to analyse particular data sets. Information on how to apply to analyse recovery data held in the EURING databank is available here. Information about the types of data that are included in the EURING databank (EDB) and about how the index was constructed maybe found here.
A list of published research that made use of EDB data can be found here.
Types of data held in the EDB
Contributing Ringing Schemes are expected to contribute at least the following types of data to the EDB:
- Ringing and final encounter details for all birds ringed in their country and recovered fresh or long-dead, sick or injured.
- Ringing and re-encounter details for all birds re-encountered alive more than 10 km from the ringing place.
In addition some schemes may also submit:
- Ringing and re-encounter details for all birds re-encountered less than 10 km from the ringing place.
- First encounter details of birds that have not been recovered.
Analysts are strongly advised to check that they understand the types of data being supplied by different Ringing Schemes. In particular, the extent to which some types of re-encounter data are available has increased dramatically in recent years; analysts should therefore pay careful attention to the temporal distribution of records. The exact distance threshold for the inclusion of short-distance live reencounters may vary between species and schemes within the above guidelines. The first table below (EDB contents – Scheme by Record Type) provides a useful summary of the types of encounter data that have been supplied by different schemes.
Contents of the EDB
The EDB index is currently being revised - new material will be added as it becomes available. Currently we have three main tables as follows:
Number of encounter records by Ringing Scheme and record type on 15 January 2020
Number of encounter records by species and record type on 15 January 2020
Number of encounter records by species and decade on 15 January 2020
