Measuring animal intelligence is a complex task because it involves multiple cognitive abilities such as problem-solving, memory, social intelligence, and adaptability. Researchers typically use different methods to assess these abilities based on the species and their cognitive skills. Here are some common methods:

Problem-Solving
Puzzle Tests: Animals are given puzzles or obstacles to solve. The time taken and the complexity of the solution reflect their intelligence.
Crows and primates often excel in these tests.
Maze Tests: For example, the speed and path memory of mice navigating a maze demonstrate their learning and memory capabilities.Memory Tests
Delayed Response Tests: Animals need to remember an object or location and recognize it after a period of time.
Food Retrieval Tasks: Observing whether squirrels can remember where they have hidden food.Social Intelligence
Cooperation and Communication: Evaluating how animals cooperate in group tasks, such as the cooperative behaviors of dolphins and
wolves.
Theory of Mind: Testing whether animals understand that others have different thoughts and intentions, commonly used with crows and
primates.Tool Use
Tool Making and Use: Observing how animals use or create tools to solve problems, such as chimpanzees and crows.Self-Awareness
Mirror Test: Determining if animals can recognize themselves in a mirror, indicating self-awareness, as seen in elephants and dolphins.

Each animal’s intelligence is shaped by its ecological environment and evolutionary pressures, leading them to exhibit unique forms of intelligence suited to their survival needs.
