Images of our visit on 11 May 2020 to the gull colony at IJmuiden Forteiland, the Netherlands, as part of our research project.
This was my first visit since 16 March, and after staying home for 8 weeks due to the corona virus lock-down it was great to be back among the gulls again.

(presumed) hybrid Lesser Black-backed Gull x Yellow-egged Gull YCMP
It was great to see 4th-calendar year YCMP again. It was seen in January in El Jadida, Morocco, so it is good to know that it has safely returned.
Interestingly, it is an offspring of YBVA (see above).
