The bird known for its intelligence and tool usage is the New Caledonian crow. These remarkable birds exhibit advanced cognitive abilities, including problem-solving skills and the capacity to create and use tools effectively. Research has shown that New Caledonian crows can fashion tools from twigs, leaves, and other materials to extract insects from tree bark or crevices. Their ability to innovate and adapt to their environment demonstrates a level of intelligence comparable to that of primates. Studies of these crows have provided valuable insights into animal cognition and behavior, helping scientists understand the evolution of intelligence and tool-making in birds and other species.
