Ravens may also consume the undigested portions of animal faeces, and human food waste. They store surplus food items, especially those containing fat, and will learn to hide such food out of the sight of other common ravens.

Group-foraging common ravens hoard their food in a number of places, and also raid the caches made by others. Cachers withdraw from conspecifics when hiding their food and usually place their caches behind structures, out of sight of potential observers.
The common raven lives in a wide variety of climates. Due to its habitat and food, the common raven has unique features that allow it to regulate osmotic challenges. Common ravens can be observed in oceans consuming water. However, when birds consume salt loaded prey or drink salt water, the body’s internal osmoregularity increases.
