imonacan,
Were you able to rule out woodpeckers for the knocks? The recordings were awsome to listen to! Very easy on my ears and crystal clear. Nice recording job. These all came from a H2 recorder? If so, I need to get one of those.
The scratching was very interesting and I thought I may be able to hear another inhale around the 2.30 mark, but not sure. Anything else Squatchy happen to you on that outing? MarkB

MarkB,
I can't completely rule out woodpeckers on the second and third clips with the percussive sounds, which occured after sunup on the overnight recording. I've heard and recorded woodpeckers gently foraging on trees, as I do some nature recording. I've never (yet) heard the tone of the pecking change.... like in those clips, and that's what causes me to think otherwise. Yes, the recordings were all from the built in mics (set on 2 channel surround) with a Zoom H2. I would not hesitate to recommend the recorder.
There was nothing seen, or no physical evidence found on the outing. There were strange movements around the perimeter of our camp noted, as well as sounds heard...including knocks, followed by a possible tree crash, and a loud thud...sounding as if something very heavy was slammed on the ground.

Thanks imonacan. That scratching sound seems almost delicate. Maybe a curiosity instead of anything aggressive. Could it have been a tongue? Any moisture on the webbing? MarkB

Barb,
I never knew bears (or any other muzzled animals) could produce popping or clicking sounds with their mouth. It's another thing to consider when monitoring the recordings, and some good info.

Here's a report that talks about "jaw popping" by agitated bears or wolves (farther down in the follow-up):

I've read other reports of agitated bears making that noise, but I've never heard it first-hand, fortunately. I still don't believe that your recording is a bear snooping around.

That's an interesting question, MarkB. I didn't notice anything wet or odd about the recorder or fake fur when I retrieved it, which was 6-7 hours after the clip of interest sounds were recorded. I agree, the scratching noise does seem delicate. I might have to try another experiment to attempt to reproduce the sound, although I'll probably never know exactly what caused it. Paying more attention to the recorder and surrounding details when I retrieve my recorder...is in my stars for the future. The area around the placement tree was swampy, buggy, and full of branch and leaf litter, and it wasn't possible to rake out a footprint trap...unfortunately. |

Barb, Thanks for the link to the report...which made for some interesting reading, and field knowledge gained. This agitated jaw popping is something we all need to be aware of, and hope we're never close enough to the source, to hear it live.
Agreed, I don't believe my recording was sounds made by a curious bear .

One thing we've found here is that Whiskey Jacks, Stellar Jays or Blue Jays are very curious birds and we've had our recorders knocked over by them and played with on more than one occasion. Is it possible that it could have been a bird?

We have heard bears produce a sound very close to a semi-jake braking,this is a sound of serious aggitation.

I once had a Coyote smack his teeth together when I loosened an arrow under him when he/she was also hunting my bait pile. The Coyote did not know where the danger was coming from and jumped, then smacked his/her teeth together a few times. I really was amazing to see predators adapt their hunting styles, it made perfect sense to me that they would frequent deer baiting areas. MarkB

In the first clip with the banging set of knocks, I am guessing the vocalization came from a Barred Owl...or else something sounding like one. I'm thinking the set of knocks and vocalization were from two different sources, but really difficult (if not impossible)to tell for sure.

imonacan,
I'm looking at the spectrum of this recording now and can see that the vocalizer is picked up equally well on both the left and right stereo channels. But the wood knocks are almost exclusively in channel 1, the left channel. You can actually pick it up in a pair of stereo head phones if you listen closely. The vocalizer is equal in both ears and the wood knocks are about 80% in the left ear.
This tells me that the vocals and the wood knocks are from two different sources.

I just went through the same recording, taking a much closer look. In the middle of the first vocalization, there is a wood knock. Hard to hear, but it's there. It's audible in both channels unlike the multiple knocks in the second vocal, which are really only audible in the left.
Vocalizations and wood knocks together always peak my interest. Unfortunately I just can't say much about the vocal, other than I've never heard one like that before. It could be a barred owl, they're supposed to be capable of some really weird sounds. But it could be something else as well.
There are also some other, fainter, wood knocks throughout the recording, and one big wood knock right after the end of the second vocalization. It can be confused with the end of the vocal, but if you slow down the playback it becomes more apparent.
Great recording.

PB, I know what you mean about the Jay family of birds being curious and bold. I had a Grey Jay grab my breakfast bar snack one morning ,in a boreal forest location.
On the fourth recording, with the scratching, crunching steps, and tongue pop sounds...it was clipped out from around the 2AM time frame on the overnight recording, so I'm doubting it was a bird. The strange thing about it, is that I never heard anything move in, or move back out....in the entire overnight recording. Whatever made the sounds... had some amazing stealth...almost unbelievable, like it came out of no where. I thought maybe a mouse or raccoon on the scratching sound, but then it doesn't account for the louder crunching steps or tongue pop. There was more scratching and what I think was a tap on the mic, a while later...but then things went silent, until the birds sang just before sunrise.

Good work on that...and I suspected two different sources on the sounds, but wasn't sure. You've picked out some other fainter details that I never noticed. Your time and effort spent, is appreciated ! |

imonacan,
My pleasure, glad I can help.
And while we're on the subject of tree knocks, BFRO just published an amazing report from a witness who saw the actual squatch, with club in hand, beating on the tree. This is a fascinating read: http://www.bfro.net/GDB/show_report.asp?id=27075

| This morning I was drinking my coffee and flipping channels and came across a show on the Planet Green channel that was discussing the seasons and animals of Russia's Ural Mountains. Sure enough, as soon as winter came, they started talking about the extremely cold temperatures and had recordings of the trees popping. It was very interesting. I was amazed at the almost continuous and similar, yet different, sounds. |
