This is quite a rare recording where the infrasound of the lekking male capercaillie is clearly audible. This infrasound is thought to be an indication of male quality and the two bands of 35 Hz and 55 Hz probably travel much longer in the forest than the rest of lek. When males utter their infrasounds just after the "plop" they go temporarily deaf so it must be quite exhausting to produce. The males go directly under my microphone and the "crisp" sounds are from dry reindeer moss.

Infrasound in lekking Capercaillie

Sound recordist Colin Hunter 
Founder of the World Sounds project

I like sounds. wich are a lot more evocative than images . Rather naturals sounds, I appreciate artistic, sociological, ecological or contemplative aproach. Besides  I start to be really interested in bioacoustic studies. Making DIY microphones projects (multicanal technic , hydros, bat recorders..) and home made wind protections.
