Description The Veluwe is home to many ravens. Since 2021, 24 raven offspring have been fitted with GPS transmitters. Of these, ten are still active, and new birds will be tagged next spring. Spatial data of all birds is accessible through a (live) Ornitela database. These devices are meant to give more insight into the habitat and food use of the ravens (e.g., do they profit from the carcasses left behind by wolves?). But many other exciting questions about raven (spatial) ecology can and should be addressed. For example:

- How does spatial behaviour, homerange and foraging behaviour change with age?
- Which foraging places/habitats are most popular (natural versus anthropogenic) and are there individual traits or factors that predict preference?
- How does social behaviour influence foraging
- Do ravens show temporal rhythms in their foraging behaviour?

Next to GPS data, there is also a database available with ringing and resighting data, which can be analyzed.

For this project, we work together with Ravenwerkgroep Nederland, and if desired, there is the opportunity to join ringing events in spring.

Open to Master Research Practice or MSc Thesis.
