Info on the use of breeding codes

For many bird species breeding season has started already. They are busily singing and displaying, inspecting potential nesting sites and transporting nesting material. The way these birds behave tells us if they are possible, probable or definite breeders. In order to allow comparable and automated analyses, standardized breeding codes have been established consisting of 20 different categories. The code was developed by the European Ornithological Atlas Committee (EOAC) and thus is applicable throughout the whole of Europe.
For not overlooking to enter this important information, ornitho.de gives you an automatic reminder when submitting your bird observations during the breeding season. These codes are valuable information for compiling species specific breeding distribution maps. Their correct usage therefore is essential.

To make everyone aware of cases when stating breeding codes is reasonable and when it is not, we have put together the most important facts and information in our new menu option “Breeding codes and their application”.

Key facts:

Please bear in mind the following when stating breeding codes
  1. Please do NOT state breeding codes when submitting data on:
    • bird assemblages which were not observed as a pair or a family,
    • roosting birds on migration or birds flying over and not showing territorial behavior or relation to a (known) territory,
    • foraging birds in unsuitable breeding habitat.
  2. Please state a breeding code only if
    • you are sure about the observed breeding behavior
    • you know the area and/or the species well enough to tell that it is definitely or very likely a breeding bird in the respective area.
  3. Please be especially cautious when stating codes A1 and B3 and only enter them in cases when it is at least very likely that the bird in question is breeding in the respective area (e.g. due to your knowledge of the area and/or the species).
  4. You do not have to state breeding codes!
    If in doubt, please choose “Ignore” (=no breeding code) when the system asks you to enter a code!
  5. Breeding codes should also be entered outside the pre-defined breeding season, e.g. when you observe breeding behaviour in winter. In these cases, please use the entry field “Breeding code” in the “Additional information” section.
  6. When observing autumn or winter song, please refrain from entering a code. Instead choose the option “singing/displaying” in the drop down menu of the entry box “Specifications (e.g. behaviour)” in the “Additional information” section.
  7. When stating definite breeding (all C-codes), we welcome any extra-added comments in the “Additional information” section. This facilitates analyses, e.g. regarding the number of families or regarding age status of the fledglings.

For a well-considered use of breeding bird codes – also in the name of the regional coordinators – thankfully yours

Patric Lorgé, Christopher König and Johannes Wahl
and the team of ornitho.de and ornitho.lu
