Colour code
The birds of this project have 1 color ring with 3 characters.
The color code consists of 3 consecutive elements:
- the letter of the color
- a hyphen ("-")
- the inscription (always 3 characters)
Example W-AAA. This bird has a white colour ring with the inscription AAA on it.
In some projects there may be a special sign (eg a dot) on the ring that may be important in recognizing the bird. Example W-A.AA
