Cachinnans - nest Lelystad 042

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 042 discovered late in season (May 28th, 2021). Positioned at breakwater dam 2, between nest 15 and nest 48 (was nest 15B). On top of bunch of branches, which appears to be an old Spoonbill nest.
  • ID uncertain: both partners unknown.
