The adult and juvenile Lesser Black-backed Gulls that were fitted with GPS loggers recently are all doing well.
The adult that recently made a trip to France has not been seen since July 10 and is believed to be on its way to Malaga, Spain via France to spend the winter there.
The other 9 adults are still present in the colony doing their daily routines.
One change could be seen though in their daily tracks: during the week of 22 – 26 July temperatures in IJmuiden rose to the mid-30 degrees Centigrade and almost all adults could be seen making trips only to the North Sea with only a few adults also going to urban areas.
The juveniles are still very much tied to their home on IJmuiden Forteiland where they are being fed by their parents, but they are starting to explore their surroundings more and more.
It will not be long before they will leave the colony and head off to their wintering grounds in Spain, Portugal, or Morocco.
