Cachinnans - nest Lelystad 175Z
General remarks:
- Eggs: Volume measured by Stonehouse (1964) and Spaans & Spaans (1975), which make comparison possible with data from Texel (Camphuysen pers comm 16.04.2020).
- Nest 175 positioned on artificial breakwater 1 at blocks. Location is only visible from south, but behind huge bush.
- Uncertainty on ID in 2024, probably one Herring Gull argenteus.
