Behavior

The Thick-billed Raven is a highly intelligent and social bird, usually found in pairs or small family groups. As the heaviest member of the crow family, it possesses a commanding presence in its native Ethiopian highlands. They are masterful fliers, often seen soaring on thermals along mountain cliffs, but they spend a significant amount of time on the ground foraging for food.

These birds have adapted remarkably well to human presence, often frequenting mountain villages and agricultural land where they scavenge for scraps. Their vocalizations are famous for being exceptionally deep and harsh—a low 'phruu-phruu' that can be heard from a great distance. Despite their size, they are playful and have been observed performing aerial acrobatics, diving and rolling in the wind for no apparent reason other than enjoyment.

Camera Tips

Capturing the Thick-billed Raven on a trail camera requires targeting their specific foraging habits in high-altitude environments. Because these ravens spend much of their time searching for insects and scraps on the ground, place your camera approximately 2 to 3 feet high, angled slightly downward. Look for flat, rocky outcroppings or areas near livestock enclosures where they are known to scavenge. In a backyard setting within their range, a stone wall or a large flat boulder serves as an ideal 'stage' for your camera to capture their massive profile.

To successfully lure this species, use high-protein baits like meat scraps or suet. Unlike smaller birds, Thick-billed Ravens are intelligent and may be suspicious of a new camera; it is often helpful to leave the camera in place for several days before expecting high-quality 'natural' behavior. Using a camera with a fast trigger speed is essential, as their movements—pecking at the ground or tossing stones—are surprisingly rapid and can lead to motion blur in slower devices.

Lighting is the biggest challenge when photographing jet-black birds. To avoid a 'black silhouette' effect, position your camera so the sun is behind it, particularly during the early morning hours. This front-lighting will help the camera sensor pick up the iridescent sheen of their feathers and the critical detail of the white patch on their nape. If your camera has adjustable exposure settings, bumping the exposure compensation up slightly (+0.3 or +0.7) can help reveal the textures in their dark plumage.

During the dry season, a water source can be an even more effective draw than food. A wide, shallow stone basin filled with fresh water can attract a pair for bathing or drinking. Be sure your camera is securely mounted; these birds are incredibly curious and strong enough to peck at or even move a camera that isn't firmly attached to a post or tree trunk. High-resolution video settings are recommended to capture their unique, deep vocalizations, which are just as impressive as their visual appearance.

Frequently Asked Questions

Thick-billed Ravens are diurnal, meaning they are active during the day. They are most frequently seen foraging in the early morning and late afternoon, taking advantage of the cooler temperatures before the midday sun.
In their native range, you can attract them by providing high-protein food like meat scraps or by having a large, flat stone area for them to land on. They are also drawn to water basins large enough for them to bathe in.
They are opportunistic omnivores. Their diet includes everything from beetle larvae found in animal dung and small mammals to carrion and leftovers from human kitchens.
Within the Ethiopian highlands, they are very common in suburban and rural mountain villages. They have little fear of humans and are frequently seen perched on rooftops or scavenging in gardens.
The easiest way is to look for the beak and the neck. The Thick-billed Raven has a much larger, deeper bill with a white tip, and a very distinct white patch on the back of its head, which the Common Raven lacks.
