- •
We validated use of animal-borne accelerometers to detect prey encounter events.
- •
Longer bottom duration of seals did not always mean greater foraging success.
- •
Seals' foraging behaviour only supported some optimal foraging models.
- •
Seals swam faster during transit when they encountered prey.
