- •
We used giving up densities to measure habitat and patch selection.
- •
When food was equal across habitats, oribi preferred feeding in the safest habitats.
- •
As food availability increased, oribi started to forage in the risky woodlands.
- •
In addition, oribi increased their use of risky patches in these woodlands.
- •
This led to an increase in risk-taking behaviour over multiple spatial scales.
