Caspian Gull n-F|C 5CY (which is offspring of y-PNED at colony Lelystad, HY=2019) breeding with partner Caspian Gull n-F|L 5CY (which is offspring of g-XLDT at colony Lelystad, HY=2019).

Season 2020 seems to be an unsuccessful breeding year for green XLDT & partner. However, in 2019 one chick of this nest was ringed black F|L, now one year old and hanging around in the neighbourhood.
All characteristics okay for a fine cachinnans.
