Singing Coyote

At 2 a.m. on Sunday the 31st of August, 2008 I recorded several groups of coyotes. I had placed three different recorders at different locations within a half mile of each other. My best recording was of a single male coyote. It was so close to the microphone that it almost overpowered the unit. I won’t ever record a better single coyote than this one. The first clip is the original and in the second clip I filtered out the cicadas.

These sounds may not be my desired target species but they are still wonderful sounds to hear and record. Hopefully I am increasing my recording skills and learning techniques to record other animals as well.

Who’s that knocking at my door?

On the 15th of August, 2008 I camped in a campground in Colorado where I heard screams earlier in June of this year.

At the time of the recording the campground had a lot of pine trees, today because of bark beetle destruction all the pines have been cut down and only leave a desecrated campground.

I placed the microphone next to my mirror on the drivers side and ran the cord inside the car and had the recorder on the dash. I covered the little red light with a piece of paper so it hopefully couldn’t be seen. I fell asleep immediately and I had a rather restless night, which is unusual for me. I did not hear anything unusual in the night and took off for Oregon the next day.

1 – at 4 sec and 7 sec you hear me moaning in my sleep.

2 – at 23 sec you can hear the latches on my car door being tried

3 – at 25 sec you hear a mumble or grumble from outside the car. This sound appears to be very similar to some other sound clips I have heard. This is the first recording I have of this type.

And now you know why I sleep in my car instead of a tent.

Colorado Recordings

The evening of Tuesday, the 22nd of July 2008 I was in Colorado where I was invited to join a fellow researcher as part of my 48 in ’08 project.

It was almost dark when I arrived at the site on Tuesday evening. I was concerned about driving down the rutted dirt road with my Toyota, not knowing for sure if I was at the correct location. So I drove back down the road and slept in my car at a small gravel pit. These sounds were picked up at 0330 a.m. I am not quite sure if they are coyote or not.

This sound clip was just before daybreak on Sunday morning. There were a lot of sheep on the hillside near our camp.

At 5 sec. there is a loud vocalization I believe designed to stir up the dogs and the flock. I can’t really describe the sound, not a howl, just strange. Then at 50 sec and 53 sec two words were spoken.

So. Illinois Sound

The evening of the 12th of July 2008 I was in Southern Illinois where I was invited to join a fellow researcher as part of my 48 in ’08 project.

After leaving the trail I recorded this most unusual sound.

Southern Illinois Sound

If any listener has an idea of what this could be please contact me. It is my opinion that perhaps it is a sound in the environment being mimicked.

Unusual calls

On the evening of the 17 of May, 2008 I was accompanied to my main research area by fellow researcher, Bob Eldridge, from New Hampshire.

We spent the next two hours walking along the roads and tractor paths that run through the oak – hickory forest. Other than several outbreaks of vocalizations from a: Barred Owl  Barred Owls  and the ever present: Whip-poor-wills   Whip-poor-wills   the evening was very quiet.

Upon returning to my vehicle I decided to try out a new sound blasting technique that I had been shown recently by John Andrews of Washington State. I had just purchased a Western Safety 50 watt battery powered megaphone. John Andrews does some awesome calls using this system and I was hoping to copy him. I did two or three calls but the night air was still without any type of response at all. So we drove four miles and got ready to try it again. I let out one call with no responses and then let out a second call. What we heard back was not what I expected. Upon first hearing the three short calls that we heard and recorded my thought was wow, someone is answering us from a ridge about a half mile away from us. I did another call but nothing further was heard.

It was now after midnight and we decided to call it a night. I drove home and uploaded the sounds on my computer. The calls I recorded were distant and faint, and most surprising short. My friend had mentioned to me in the field that the returned call almost sounded like my voice. I thought that odd but upon listening to them I tend to agree. Was someone or something a good enough mimic to not only return my call but also make it sound somewhat like my voice?

Sasquatch Sounds

One of the most significant new recordings was recorded by DB Donlon in April of 2007 in Ohio. This new sound clip soon became known to the bigfoot community.

The recording was brought to the attention of Ron Morehead of  Sierra Sounds, who thought it was significant enough to mention it in July of 2007 while a guest on

COAST TO COAST AM WITH GEORGE NOORY

Ron includes a link on his website to the sound clip.

Illinois Howl

This information was originally posted on my website about a year and a half ago.

When THE BLOGSQUATCHER started his blog this was the topic of one of his earlier posts. So you may want to check out this information also over on his blog for Thursday, October 11, 2007 titled:

The voice of bigfoot? The Illinois Howl

———————————————————————————
The Illinois Howl

This post will attempt to answer some of the following questions:

What is the Illinois Howl?
What animal is making these vocalizations?
What are its characteristics?
What does it sound like compared to other animals?
What does it look like graphically compared to other animals?
Why am I wasting my time on something so obvious?

What is the Illinois Howl?

The Illinois Howl is the vocalizations of presently an unseen and unknown animal. They were first recorded on the 4th of April, 2006. It was recorded five times that spring. I record nature sounds every night. The following five clips have been cleaned up to eliminate rumbling and hiss.

05.24.2006 Illinois Howl
This was recorded at 04:14 in the morning.

05.18.2006 Illinois Howl
This was recorded at 01:30 in the morning.

04.12.2006 Illinois Howl
This was recorded at 11:58 in the evening.

04.07.2006 Illinois Howl
This was recorded at 4:45 in the morning.

04.04.2006 Illinois Howl
This was recorded at 3:45 in the morning.

The complete series of recorded howls can be found at:

Illinois Howl Recordings

What animal is making these vocalizations?

There are many opinions as to the origins of these sounds. Opinions range from coyote, coy-dog, dog, wolf, fox, bigfoot, cow.

As an attempt to get an answer I posted this question and a poll on many of the outdoor forums on the internet. These discussions can be found at:

Unusual Howl – 24 Hour Campfire

What Do You Think Of This One? – Bigfoot Forums
What Kind Of Howl Is This?? – Bigfoot Forums
What Animal Do You Think This Is? – Bigfoot Forums

Unusual Howl – Jesses Hunting & Outdoors (JHO) Forum

What kind of howl is this? – Rimfirecentral
Unusual Illinois Howl – Shooters Forum
Unusual Howl – US Hunting Forums

What are its characteristics?

On the five recordings it exhibits several traits that are discernible on all five. The howl starts out as a low volume sound that seems like it is just clearing its throat. It then delivers three somewhat equal volume howls. The second and third howl are spaced a little bit further apart than the first and second howl. The waveform in Cool Edit 2 Pro looks like –

DB Donlon has done extensive research on this sound and has written the following analysis:

Stan’s sound has a main frequency of 689Hz and a fundamental of 344Hz, according to SoundRuler.

(SoundRuler is a free application, now several years old (a new version is promised this year) that does have limitations. I think it was made for birders, for instance, and may therefore be based on assumptions that aren’t so good for large mammals.)

In SoundForge, a completely different program (that costs money) you can look at prettier sonograms. I can also watch the PowerGraph in real time, and see where all the power of the call is going. By looking at the sounds in the SoundForge Powergraph window, I can see how the frequencies are interrelating. For instance, Stan’s howl gets “dirty” several times, where the voice is no longer producing a clear note, but instead is moving into the growly “noise” range. We know that dogs can do that, but so can any other mammal that has enough voice, including man, and anything that roars. The dog file I have does a little of it at the beginning of its call too. So there is a similarity between them. But they do not match in where they use this modulation of the sound. You might not expect them to, but then we also all know the classic wolf call, and how that modulates. It’s a classic because wolves do it, rather than using a completely chaotic repretoir of noises such that we can detect no pattern. This is not a major point, but so far as it goes, Stan’s sound isn’t matching what other dog calls I can find do in the way that it modulates its call. So it sounds like what a dog can do, but it sounds different from my dog examples. Make sense?

Here’s another difference. You can see that both calls are very close to the microphone, as nature sounds go, because the high end information is well preserved above the noise-floor. I limited my view to around 4.2KHz so that I could see the fine details of what was going on in there, and both sounds gave me numbers in the 3.8-3.9KHz range. So insofar as distance from microphone goes, it appears there isn’t a difference that makes a distinction. But the dog sound looks absolutely normal, hitting almost all its harmonics on the way up. These are the rough numbers in Hz:
Dog Howl:

420 648 850 1073 1269 1508 1720 2521 2997 3260 3417 3895

The fundamental frequency is at about 220Hz here, so every number above should be a multiple of 220. The differences are because of measurement errors and the fact we are using software that wasn’t designed to do exactly what we’re asking it to do. I have to hold the mouse cursor and read the number, write it down, etc. So 850 ought to be 860, or the fundamental was perhaps closer to the 215Hz that SoundRuler gave us (though SoundRuler was giving us the average, and I’m taking a snapshot of the “moving” sound, so we can expect this kind of difference).

Stan’s sound is a little different.

Illinois Howl:

xxx 662 971 1309 xxxx 1960 2270 2615 xxxx xxxx xxxx 3936

There are gaps, and the numbers don’t match the fundamental as closely as the dog’s sound did.

These are two important points, I think, to bear in mind. The sound sounds weird to us for these reasons — it doesn’t conform to what we normally expect. I can explain the fact that the numbers don’t match the fundamental, which ought to be around 340Hz according to SoundRuler, because the noise this animal is making is dirtier than the sound the dog is making. It’s much more like a roar than the dog’s howl is, even at those points where it sounds relatively clear. What this means is that when I move my cursor looking for the peak, I have a lot of wiggle room. In figurative words, I choose the highest relative peak on a plateau. The frequency looks like a plateau because the animal was introducing distortion into its voice — kind of like a guitar with a stomp box. Use enough of that distortion and you just get a noisey roar. Use a little, and it sounds cool. I don’t know enough about dogs and their barks to say that dogs don’t do this sometimes in exactly this way, but I don’t have any sound files of them doing it.

About the gaps I am just confused. I can explain the upper gaps away due to distance, although that peak at 3.9KHz was a good one. I expected the other peaks to be there. Maybe if I focused down in on those frequencies, I’d find them, but then we’d still have to explain why they had been so damped when other frequencies hadn’t. I checked some of Stan’s other files of other animals in the same location, and it doesn’t appear that there is any environmental reason for it. And I noted the same kind of gapping in the other files with this same animal doing its call. I don’t know what it means, but I am entertaining the idea that it means something.. The gap where the 1.6KHz peak should be is a strange one.

So while I won’t come out and say, “Yes, this is it, this is a bigfoot call,” I’m not writing these sounds off. I will say that I doubt this call was made by a coyote, as has been hypothesized elsewhere, or any other mammal smaller than a large dog. All the coyote calls I have have a fundamental at around 600Hz, much too high to be the Illinois Howler.

If it’s a dog or a wolf, we ought to be able to find matches for the Illinois Howl that have already been recorded, or get new clean recordings of the howls with the animals under observation.

What does it sound like compared to other animals?

For comparison let’s look at the Illinois Howl and three other known animals.

What does it look like graphically compared to other animals?

Visually each animals howl is seen in the waveform view. I have used Adobe Audition 2.0 as the sound editor:

Then each animal’s howl is seen in the spectral view:

Why am I wasting my time on something so obvious?

Many people have stated that it is quite obvious that the Illinois Howl is nothing other than a coyote or dog, certainly canine. They wonder why I would be so naive to suggest that this sound is anything else. On the other side of the coin are those people who have told me that they have spent a great deal of time in the woods and maintain that it is impossible to be a coyote.

My original interest in the sounds in the woods and along the creek behind my home started last spring. On the 23rd of May, 2005 I went out into my backyard to check on my dog, Belle. She had been barking for some time and would just not settle down. So I grabbed my 3rd gen night vision and proceeded to take her toward the creek and show her where I had seen deer bedding down. As I reached the edge of the yard I heard what sounded like a very large roar coming from the creek bottom. The call was very deep and full. The sound lasted for about 15 seconds and then all was quiet. It appeared to be coming from something with a huge chest. The call had a somewhat human quality to it. I went into the house to ask my wife to come and listen. Nothing else was heard. The dog settled down and did not bark again that evening.

Since that time I have been placing my audio recorder down near the creek or on the hill above it. Although this is Central Illinois we have a large deer population. Other wildlife seen along this creek include several sightings of mountain lion and bobcat. We also have a sizable population of coyotes. About 3 miles to the east of me is a state park with a large lake and lots of marshy areas. And about 10 miles north of our home the creek flows into the South Fork of the Sangamon River.

Will this riddle of the Illinois Howl ever be solved. Yes, of course!

A Quiz and a Challenge – What are These Sounds in the Night?

One of the most interesting areas of research in wildlife is sounds. Whether it is different frogs croaking, bird singing or coyotes howling we can make recordings and do computer analysis of these sounds.

In the area of bird identification when so many times the birder is not able to see the vocalist because of heavy brush, bird songs and calls have become a major resource. CD collections of American birds are inexpensive. Examples are:

Stokes Field Guide to Bird Songs

A Field Guide to Bird Songs: Eastern and Central North America (Peterson Field Guides)

The major institution that is deeply involved with bird sounds is:

Cornell Lab of Ornithology

When it comes to mammal sounds it is more difficult. Darkness does not lend itself to easy identification of sounds. Most birds are active in the daytime (owls and nighthawks and a few others being the exception). The mammals are a different story. Although all mammals are seen at different times of the day, other than the squirrel family, most are chiefly active in the night.

Numerous websites have collections of mammal sounds:

Guide to Animal Sounds on the Net

Naturesongs

JungleWalk

Sounddogs

Hunting websites often carry large collections of the more common mammals:

Varmint Al’s Coyote Hunting Page

Allpredatorcalls

Bioacoustics

According to Wikipedia:
Bioacoustics is the study of how animals use sound for communication and echolocation.

Major institutions that are involved in bioacoustics include:

Texas A & M University-Corpus Christ

Cornell Lab of Ornithology
Bioacoustics Research Program (note: also includes mammals)

Sound Analysis

The advent of computers has allowed scientists and amateur alike to study sounds in an objective manner. It is not enough to say “oh that sounds like a coyote or that is just a mountain lion screaming”. It needs to be recorded with high quality field recorders and microphones. It then needs to be analyzed by computer software.

There are many different programs for evaluating sounds:

Adobe Audition

Audacity

Soundruler

For a longer list of programs check out:

Sound Analysis Software for bioacoustics

A Quiz and a Challenge:

What is this animal? I recorded this sound during April and May in Central Illinois along a creek in a mixed oak-hickory forest.

Illinois Howl – Recording

To answer the challenge one must be able to have a recording that is good enough quality to be analyzed. A poorly recorded and distorted recording has no value. To be considered the same animal the recording must:

1. Display the same pattern.
2. Display the same resonant frequency and overtones.

If you think you know what this animal is please send me a recording for analysis. My email address is: stancourtney@hotmail.com
