My favorite birds are the golden eagle and red kites. In my region, golden eagle do not exist, but in the alps, they do. When I was in Austria 2019, I really hoped to see them in natura and on my third day there, I finally saw my first golden eagle in the wild nature. Red kites on the otherside are really common here. I often see one flying over my house.
Another birds I like are other eagles owls, Parrots (we even have some parrots in free naure here in western germany), kingfisher, cranes, storks and grey herons.
