You may come across an unusual number of sick or dead animals of a particular species or several species of wild animals.
In such cases, please notify the DWHC of this observation, using this submission form, sending an email (dwhc@uu.nl), or by giving a call (030-2537925).
In most cases of dead birds, DWHC will be able to investigate the cause of death, but occasionally this should be done through another organisation, as detailed here.
