In both January and February 2023, a Eurasian sparrowhawk (Accipiter nisus) was examined by the DWHC. Both sparrowhawks had inflammations of the oral mucosa, and one also had an inflammation of the crop. In both birds these inflammations were caused by the nematode (roundworm) Eucoleus dispar.

At this moment – February 2023 – there are signals of high-pathogenic avian influenza (HPAI) causing death in black-headed gulls in France, Belgium, Germany and the Netherlands.

The Netherlands Food and Consumer Product Safety Authority (NVWA) has confirmed avian influenza H5N1 in two fox cubs found in the province of Groningen.

Since October 2020 The DWHC and Sovon have collected more than 400 dead wild birds to be tested for avian influenza virus at WBVR in Lelystad, The Netherlands.  Most of the collected birds were individuals, because the NVWA deal with the reports of 3 or more dead waterbirds.

Overview of test results of submissions via DWHC and Sovon between October and December 2020

Every week, the NVWA* creates a new map with the locations of dead wild birds that tested positive for the highly pathogenic avian influenza (bird flu) H5N8.

In the undermentioned wild birds is highly pathogenic avian influenza (HPAI) H5N8 or HPAI  H5N1 confirmed.
This list is based upon reports of the Dutch government to OIE this autumn/winter until November 17.
