One of the reasons for colour-ringing a bird is to track its relations with other birds, such as partners, offspring, siblings, and so on.
In the Marked Birds Database this can be tracked by using the ‘Relations’ feature.
The following types of relations can be tracked:
Relations are tracked based on the year in which they took place. This makes it possible to for example follow which partner a bird had for each year. For relation types other than ‘partner’, the birth year can be used.
- Bird A was a partner of bird B in 2019.
- Bird A was born in 2019 and has bird B as a father and bird C as a mother.
- Bird A and bird B had bird C as a son/daughter in 2019.
Relations can be created for known birds that exist in the database, or for unknown birds which are:
- Have a metal ring only which has not been read
- Have color rings which have not been read
How to access
Relations are shown in the following locations:
- On the Bird Overview screen as a tab together with the Notes field
