An Ethiopian wolf licks nectar from the Ethiopian red hot poker flower Adrien Lesaffre
Ethiopian wolves feed on the sweet nectar of a local flower, picking up pollen on their snouts as they do so – which may make them the first carnivores discovered to act as pollinators.
The Ethiopian wolf (Canis simensis) is the rarest wild canid species in the world and Africa鈥檚 most threatened carnivore. Endemic to the Ethiopian Highlands, fewer than 500 individuals survive.

at the University of Oxford and her colleagues observed wild Ethiopian wolves lapping up the nectar of Ethiopian red hot poker (Kniphofia foliosa) flowers. Local people in the mountains have traditionally聽used the nectar as a sweetener for coffee and on flat bread.
The wolves are thought to be the first large carnivore species ever to be recorded regularly feeding on nectar.
鈥淔or large carnivores, such as wolves, nectar-feeding is very unusual, due to the lack of physical adaptations, such as a long tongue or specialised snout, and because most flowers are too fragile or produce too little nectar to be interesting for large animals,鈥 says Lai.
The sturdy, nectar-rich flower heads of the poker plant make this behaviour possible, she says. 鈥淭o my knowledge, no other large carnivorous predator exhibits nectar-feeding, though some omnivorous bears may opportunistically forage for nectar, albeit rarely and poorly documented.鈥
Some of the wolves were seen visiting as many as 30 blooms in a single trip. As they lick the nectar, the wolves鈥 muzzles get covered in pollen, which they could potentially be transferring from flower to flower as they feed.

鈥淭he behaviour is interesting because it shows nectar-feeding and pollination by non-flying mammals might be more widespread than currently recognised, and that the ecological significance of these lesser-known pollinators might be more important than we think,鈥 says Lai. 鈥淚t鈥檚 very exciting.鈥
Lai and her colleagues at the聽 now hope to dig deeper into the behaviour and its ramifications. 鈥淭rying to confirm actual pollination by the wolves would be ideal, but that would be quite challenging,鈥 she says. 鈥淚鈥檓 also very interested in the social learning aspect of the behaviour. We鈥檝e seen this year adults bringing their juveniles to the flower fields, which could indicate cultural transmission.鈥
