A murder is the collective noun for a group of crows.
Crows are large, black birds found throughout the world. They are highly intelligent and social animals, and live in large groups called ‘murders’. Crows are known for their loud calls, which can sound like a loud ‘caw’. They are omnivorous, and feed on a variety of food items, such as insects, seeds, and carrion. Crows are also known for their problem-solving abilities and are often seen using tools to obtain food.
