IJmuiden Lesser Black-backed Gulls in Morocco – January 2019

During our recent gull reading trip to Morocco last month (about which more in a later post), I was happy to come across several Lesser Black-backed Gulls from our IJmuiden Forteiland project in the Netherlands:

  • Second-calendar years Green YCSP and YCTL
  • Fourth-calendar year Green YCDU
  • Adults Green YBMF, Green YCJW, and Red RWN

Some of them I was able to photograph, as shown below.

Green YBMF

Our first sighting of an IJmuiden Gull was adult YBMF at the salt pans at Lagune de Sidi Moussa, north of Oualidia, on January 13, 2019

We saw it at the exact same spot where we observed it 2 years ago.

Note the active primary moult: P10 is not yet fully grown.

After our observation in 2017, YBMF actually returned to the Netherlands but even though it was observed just south of the IJmuiden colony, it was never observed it there.

Green YCSP

We came across second-calendar year YCSP at the landfill of El Jadida, on January 14, 2019, in a group of about 10,000 other gulls.

YCSP is one of 39 juvenile Lesser Black-backed Gulls that we colour-ringed in July 2018 and I have fond memories of it because it photographed well while it was still in the colony.

Red RWN

Ringed as a pullus by Mike Marsh in Suffolk, United Kindom, in 2005, Red RWN has been breeding in our Dutch IJmuiden colony since 2010 and is therefore very much part of our project.

We came across her at the landfill of El Jadida, on January 15, 2019, and she was actually first observed there during her first calendar year back in 2005. It is likely that she is wintering there every year.

We know her well because her territory is in a visible location in the colony.

It will be great to see her back again in a few months (if she returns), knowing that I have seen her all the way in Morocco.
