The Gouldian Finch, a tropical bird measuring only about 15 centimeters in size, stands out with one of the most striking plumages in the entire animal kingdom. These vibrant birds often appear as if they were pieced together from colorful patches. As is often the case in the bird world, the males sport more eye-catching plumage. Among them, the red ones are the most aggressive. Fun fact: Gouldian Finches exhibit remarkable plumage diversity, with red males being particularly aggressive.
