Lesser Black-backed Gull (graellsii) Y.CTX adult, May 2019 - May 2020, IJmuiden, the Netherlands. Picture: Maarten van Kleinwee.
Ringed as breeding adult in season 2019 at Forteiland, IJmuiden. Ringed by Fred Cottaar ringing team.
Partner is hybrid g-Y.BVA, which had an unringed partner already in 2016-2018 (which may well be the later, in 2019, ringed g-Y.CTX).
Faithful pair, both in partner choice and location, breeding at the very same spot in the colony back-to-back seasons, until g-Y.BVA suddenly didn't turn up anymore after May 30 2023. Despite being single parent, g-Y.CTX managed to raise both chicks in 2023 (very unusual).
