While falcons aren’t overly distinct from other birds of prey, you can recognize them by their smaller size or the dark, mustache-like markings on their cheeks.
You don’t have to be a falconer or an expert on birds of prey to recognize that the bird in your dreams is a falcon. In dreams, you often know what you’re dealing with without having much knowledge of the subject.
If you’re unsure that the bird from your dream is a falcon, they are similar to eagles and hawks. They are smaller in size and have excellent sight. Like other raptor birds, falcons are superb hunters and have a fair amount of symbolism associated with them.
