Rat can't forage easily a crow biting its tail

The rat is looking for something to eat, and a crow is making small unsuccessful attacks against it and it tries to catch it by pecking at it with its beak. The crow is a species of omnivorous bird from the Corvidae family of birds that includes ravens rooks, nutcrackers, jays, and magpies that eat various animals and carrion for their meat-eating diets and a variety of seeds and grains, fruits and nuts, and almost anything they can find when they are foraging and feeding. Crows have a predatorial instinct to attack hunt and eat other animals they can handle, such as rats, mice, and other small mammals, reptiles, and amphibians. The crows will also eat other birds and their babies, especially in the avian breeding seasons, and this type of predator eats animal prey feeding behaviour has evolved over millions of years to enable them to have an extensive menu of wild protein-rich food. Food eaten without chewing is how crows and all birds eat their food because they have no teeth for crushing, and dining on big or small portions by swallowing in gulps is how they feed. Many problem-solving tests have been done with crows to prove that they are a bird with high intelligence. The crows are brilliant problem-solving birds. The crows are avian animals that can be found living and breeding in many habitats throughout the world.
