Bird flu found in Common Kestrel



In recent weeks, Common Kestrels infected with highly pathogenic bird flu (H5N1) have been found in several places in the Netherlands. In January 2025, seven Common Kestrels were examined at the DWHC, of ​​which three were found to be infected with bird flu (see map). Two of these birds were found in Friesland, and one in North-Holland.

It is remarkable that the virus is found in the Common Kestrel. Considering this bird species mainly feeds on field mice, it is likely that they rarely come into contact with infected prey. However, the supply of field mice is currently very small due to the wet weather earlier this winter, which means that it is possible that the common kestrels will switch to other prey. Barnacle Geese in particular are currently being affected by bird flu. Common Kestrels can get infected by the virus by eating infected carcasses.

Please keep reporting

It is important to continue to monitor the development of bird flu infections in the Common Kestrel. Reports of dead Kestrels can be submitted to Sovon (sovon.nl/dodevogels) or via our online form (dwhc.nl/meldingsformulier). Bird flu is a zoonosis (a disease that can be transmitted from animals to humans). The DWHC advises the public to be careful when approaching dead wild birds and to adhere to hygiene measures: Guideline for dealing with wild animals with bird flu | Report | Rijksoverheid.nl (only available in Dutch). Please be mindful not to touch the animal with your bare hands. Please read the message from Sovon for more information on the Common Kestrel.
