Crested Goshawk, scientific name Accipiter trivirgatus, is a common eagle species in Taiwan. After the heavy rain today it flew to the antenna near my house to dry its wings. Wow, it's really a rare picture, its wings are fully unfolded, and the lines on the wings are very clear, it's really beautiful! In the recorded video, he will shake his whole body after drying his wings, and he looks like an angry bird during the process, which is very interesting and cute.
