These birds do not have very positive associations. They do not arouse sympathy, they have a sinister appearance resembling scavengers. Besides, ravens are not typical inhabitants of London. They come to the Tower either from breeding or from donations. Meanwhile, one of the current raven guardians, Christopher Skaife, has a completely different view of these birds. He wrote a book based on many years of observing them in the London fortress. It turns out that ravens are very intelligent birds. They live in a hierarchical community and have different characters, personalities, and behaviors, a sense of humor, and the ability to show various emotions. They can lie, cheat, play, and think abstractly. Ravens are the most intriguing birds on Earth.
