# Food Chain Hazing (DD-692)

> Lions and spotted hyenas are Africa's two largest carnivores. They eat many of the same prey, so they compete directly for food. Lions often kill hyenas and their cubs, but they usually don't eat them. The killing removes a competitor rather than providing a meal. In Namibia's Etosha National Park, lions caused 71% of recorded hyena deaths in a one-year study (Trinkel & Kastberger, 2005). The rivalry runs both ways. Spotted hyenas are skilled hunters that kill most of their own food, and in some places they take carcasses from lions, especially when no adult male lions are around. Hyenas also 'mob' lions in groups to drive them away from dens.

## Quick facts

- **DD-692-F01**: In one Etosha study, 71% of hyena deaths were caused by lions. _(Write-up · Exhibit A (Competitors, not prey))_
- **DD-692-F02**: Spotted hyenas kill most of the food they eat. _(Write-up · Exhibit A (Competitors, not prey))_

## Write-up

Rivals, not dinner. Lions kill hyenas to cut competition, but rarely eat them.

1. **Competitors, not prey**: Lions and spotted hyenas overlap heavily in diet. Lions kill hyenas to reduce competition for food, and in some ecosystems they're the main cause of hyena deaths.
2. **Not just scavengers**: Spotted hyenas are excellent hunters that feed mainly on hoofed animals they kill themselves. Working together, they can bring down prey as large as a buffalo or giraffe.
3. **Theft goes both ways**: Each species steals from the other. In Ngorongoro Crater, hyenas took every lion kill they contested when adult male lions were absent. In Etosha, lions took the carcass in every observed case where hyenas had made the kill.
4. **Numbers and males matter**: Who wins depends on the ratio of hyenas to lions at a carcass and on whether adult male lions are present.
5. **Mobbing**: Hyenas sometimes gang up on lions even when there's no food involved, which researchers interpret as a way to drive them away from dens and protect cubs.

## Reel vs. record

- **Wrong label**: spotted hyenas aren't mainly scavengers. They kill most of their own food, though they also scavenge and steal (Current Biology; The Conversation).
- **Missing context**: lions usually kill hyenas to remove a competitor, not to eat them.
- **Note**: Two-way rivalry: hyenas also take kills from lions. In Ngorongoro they won every contest when no adult male lions were present (Trinkel & Kastberger, 2005).
- **Scale**: in Etosha, lions caused 71% of recorded hyena deaths over a one-year study.
- **Missing behavior**: hyena clans 'mob' lions as a group, apparently to protect their dens and cubs.

### Transcript

DID YOU KNOW? Lions are apex predators that sometimes target hyenas, using their superior strength and coordination to dominate or even cripple rival scavengers. When competing over food or territory, a pride of lions can overpower a hyena, delivering powerful bites to the legs, shoulders, or neck, which can immobilize or severely injure it. NOW YOU KNOW!

## Questions & answers

**Q: Do lions usually eat the hyenas they kill?**  
A: They usually kill hyenas to remove a competitor, not for food. _(Source: Write-up · Exhibit A (Competitors, not prey) · Trinkel & Kastberger (2005), Competitive interactions between spotted hyenas and lions in the Etosha National Park, Namibia, African Journal of Ecology)_

**Q: Where does most of a spotted hyena's food come from?**  
A: Spotted hyenas are skilled hunters. _(Source: Write-up · Exhibit B (Not just scavengers) · Holekamp & Dloniak / Current Biology (2006): Spotted hyenas (quick guide); The Conversation: In defence of hyenas, they're not just scavengers)_

**Q: What share of hyena deaths did lions cause in the Etosha study?**  
A: 71%. _(Source: Write-up · Exhibit A (Competitors, not prey) · Trinkel & Kastberger (2005), Competitive interactions between spotted hyenas and lions in the Etosha National Park, Namibia, African Journal of Ecology)_

**Q: What decides who wins at a carcass?**  
A: The hyena-to-lion ratio and whether adult males are present. _(Source: Write-up · Exhibit D (Numbers and males matter) · Trinkel & Kastberger (2005), Competitive interactions between spotted hyenas and lions in the Etosha National Park, Namibia, African Journal of Ecology)_

**Q: What is 'mobbing'?**  
A: Hyenas confront lions as a group, often near their dens. _(Source: Write-up · Exhibit E (Mobbing) · Trinkel & Kastberger (2005), Competitive interactions between spotted hyenas and lions in the Etosha National Park, Namibia, African Journal of Ecology)_
