Capercaillie mating gliff

I found few days ago nice mating cliff of Capercaillie. I spend a night there in tent hide listening to sounds of spring time forest. I was ready with my tent and equipment at 17.30 and started to wait. At 18.10 arrived big male Capercaillie and landed very noisy way to place on branch of pine tree. Two hours later arrived two birds more to place little bit further behind threes from me. I only heard they arrival noisy way.  I went to sleep to my warm sleeping back at 21.15 wondering coming morning and nice shots. I woke up 03.30 am, settled up my camera and did make more space to move in tent. At 03.45 started black grouses singing further around me. At 03.55 arrived to site big male Capercaillie similar noisy way as evening. Were very silent a moment, sang few line only and flew away. Then those other birds (females) followed him and suddenly the place vere empty. I was sad a bit, but knew that birds went to the main legging place somewhere nearby. I waited to 05.05 sun rise and collected my staff away and went to looking for that main legging place. I drove trough all back roads nearby listening to birds sounds, but without success. I arrived back to cliff hoping that Capercaillie comes back to his territory. Now I settled up only my camouflage net for the hide and wearing on my camouflage suit. I was ready at 07.30, when at 07.45 heard a enormous noisy way taking down my Capercaillie just on top of the mating cliff. And suddenly started very intense dancing and singing out there. I took several shots and were happy, I knew it happens.  It takes about 15 minutes and suddenly bird and two others who followed that male bird was gone.. Wildlife is marvelous..! The Caip were lost  half of his tail on mornings fights somewhere.
