Cachinnans - nest Lelystad 072
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).
- Location marked with "red spot & white circle" on large block.
- Nest 072 on breakwater dam 1 at north side, section with dense vegetation. 2 meters north of nest 66 ("66" marked on blocks). But position unclear.
- ID for nest 072 uncertain in 2021, probably Caspian Gulls cachinnans. Limited data.
No images. Visits and data.

Uncertainty about location. Long intense search for nests 66 & 72, no eggs / no chicks, but alarming parent over head. Dense vegetation doesn't help. |
|
One block marked red spot with white circle, 5 meters behind this is an empty nest. Was 66??? |
|
Maybe nest 72 is nest 39-2020? |
