For Pygmy Owl is no clear sexual dimorphism, only the female is slightly larger than the male. Today, filmed female Pygmy Owl in Białowieża Forest. How I can you be sure? Only female call like the bird in the movie. For a moment I saw 2 Pygmy Owls next to each other and the female is about 1/4 larger than the male. Bialowieza Forest spring begins to develop its wings 🙂
