Since 2014, I manage the collection of mammals and birds at Naturalis. Amongst other things, I ensure that this collection remains well conserved, that it is accessible for research, that everybody can make use of the digital data and that new specimens are added to the collection. Obviously, I also work on presentations for the public and I ensure that other museums can borrow collection items.

The birds and mammals collection consists of about 500,000 specimens. These include mounted skins and skeletons, but also individual bones, mounted zoological specimens, and specimens in alcohol.

The Naturalis collection contains 400,000 bird specimens and 100,000 mammal specimens, and is still growing. Animals that are found dead are often included in the collection. Besides recent specimens, there are also specimens present that have remained conserved in the collection for more than 200 years and were part of the collection of our first director, the ornithologist C.J. Temminck. These specimens were therefore already present in the collection at the start of Naturalis. The collection is frequently consulted by researchers but is also of immense value for our own exhibition and for those of other museums.

The subjects that I am currently working on include a catalogue for scientific categories and new acquisitions for the collections, such as the bearded vulture and golden Jackal.
