No, ravens are not extinct. They are widespread and can be found in various habitats across the Northern Hemisphere. Ravens are known for their intelligence and adaptability, which has helped them survive and thrive in different environments. **

There are scarecrow-like devices specifically designed to deter ravens and other birds from nesting in certain areas. These devices often use visual and auditory deterrents to make the area less appealing for nesting. You can find these devices at garden centers or online retailers. It's important to follow local regulations and guidelines for deterring birds, as some methods may be restricted or require permits. **

Ravens are omnivorous birds and have a varied diet. They primarily eat carrion, insects, small mammals, and bird eggs. They are also known to scavenge for human food scraps and can be opportunistic feeders, consuming a wide range of items including fruits, seeds, and even garbage. Ravens are adaptable and resourceful when it comes to finding food, and their diet can vary depending on their habitat and the availability of food sources. **

Ravens are opportunistic feeders and have been known to prey on small animals, including young or injured cats. However, it is not common for ravens to actively hunt and catch healthy adult cats. Cats are agile and quick, making them difficult for ravens to catch. While there may be rare instances of ravens preying on cats, it is not a typical behavior for them. **

Ravens are highly intelligent birds and have been known to form strong bonds with humans. While they may not actively protect people in the same way a guard dog would, they can alert their human companions to potential dangers and threats. In some cultures, ravens are seen as protectors and symbols of good luck. Additionally, their keen senses and ability to communicate with humans could potentially be used to help protect people in certain situations. **

Ravens can be tamed to a certain extent, but they are not typically as easily domesticated as some other birds like parrots or doves. Ravens are highly intelligent and can form bonds with humans, but they still retain their wild instincts and may not always be predictable or obedient. With patience, consistency, and proper training, some ravens can learn to interact with humans in a controlled environment. **

Ravens are wild birds and cannot be bought or sold as pets. In many places, it is also illegal to keep ravens as pets due to their protected status as migratory birds. Additionally, ravens are highly intelligent and social creatures that require a specific environment and care that cannot be provided in a typical household setting. Therefore, it is not possible to buy ravens as pets. **

Ravens are considered to be highly intelligent birds due to their problem-solving abilities, complex social structures, and advanced communication skills. They have been observed using tools, planning for the future, and even showing empathy towards other ravens. Their large brains relative to their body size also contribute to their intelligence. Additionally, their ability to adapt to various environments and learn from their experiences further showcases their intelligence. **
