In late June 2016 I had the great fortune to spend some time with a Great Grey Owl family, also known as the silent hunter. For example, it often sits for long periods on a branch or pole in the middle of a field or in the forest as in my case, patiently waiting to hear a change in the grass. Its characteristic head shape with several black rings and the yellow eyes. The head can have a circumference of 50 cm and serves as a dish to amplify every sound. It is adapted for a quiet and efficient hunt.
