I am glad that our world is so rich in variety of animals and birds as well as flora too. Otherwise it would be too boring. The feathers even of the same bird but on different part of body or wings are various. On wings are strong and robust on the chest are soft like fuzz, the colour pattern differs too. Thank you for beautiful examples on your photo and the name of owls, I am not good in that so it was interesting to find our more :)
