Fifth year in a row on different Capercaillie leks. This year started out slowly at 04.10 AM and about 5 males were displaying without much enthusiam until 07.30 when four females arrived. All of a sudden I had 15 males in front of the hide! Where did they come from. Wonderful recordings of the (almost) infrasound (32 Hz) when the males go "blind". If you listen carefully you will also hear mating of Pygmy Owl and hear when the Capercaillie males go quiet when a Goshawk calls in the distance.
