Argenteus - nest Lelystad r-6.C

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 r-6.C positioned on breakwater dam 1 south, small Blackberry bush at edge of tarmac, 12 meters east of nest 128. Flagged pole placed next to nest.
• ID uncertain in 2022: one parent is adult Herring Gull argenteus, trapped as breeder in 2022 and ringed r[6.C]. Probably partner also Herring Gull.
