Up on the forest, snow covers the ground. I flush an adult male Goshawk from the roadside and it keeps flying in front of me for quite some time before it actually perches in a treetop when we come to a clearing. 

    Not far from that I stop to investigate a track of footprints crossing the road. 

    I am just realising that they come from a small Grouse, when I hear a Hazelgrouse cock whistling some 20 meters away in the dense forest. I use my whistle to imitate it and it answers me back for around 15 minutes or so, without moving out into the open to give me a clear view. 

Funny, because at this very spot  I had a male who behaved just like this a couple of years ago. The same?
