Encountered a couple new and old sounds this weekend and wondering what they are?
1) It sounds the same tone as a grouse drumming, maybe a little deeper. The pace is that of dropping a rubber ball on the table... as the energy decreases, each bounce is lower, hence an increasingly rapid beat. I have heard this before, but thought it was my own pulse. I heard it a lot this weekend and thought I was having a jammer or something until caddisgirl tells me she hears it too. Feels like an artery clogging up in my brain and makes me all dizzy. Is this some kind of grouse auditory attack?
2. This one sounds like your classic Hollywood submarine. Very loud and all through the night. BOOP.... BOOP... BOOP... about 3-5 seconds in between. Very loud, enough to echo. Was thinking some kind of owl or night hawk? Pretty sure a feathered UFO of some kind.
