Key Concepts
The Relationship between Ravens and Wolves
Mutualism: Ravens are commonly known as "wolf birds" due to their relationship with wolves.
Food Source: Ravens benefit from wolves by consuming carrion left by wolf kills.
Ravens often arrive at carcasses soon after a kill or are present during the hunt.
Up to 135 ravens have been observed feeding on a single carcass.
They not only consume but also cache (store) the food.
In some cases, ravens may harvest more from a carcass than wolves.
Social Interactions: Ravens display advanced social skills and communication.
They draw attention to carcasses by making noise, allowing larger scavengers to access the food.
Ravens have playful interactions with wolves, especially pups and yearlings, such as playing tug-of-war with sticks or teasing them by pulling tails.
Some ravens may develop bonds with specific wolves in a pack.
